Four types of sensory neuron
Sensory neurons also known as afferent neurons are neurons that convert a specific type of stimulus, via their receptors, into action potentials or graded potentials.[citation needed] This process is called sensory transduction. The cell bodies of the sensory neurons are located in the dorsal ganglia of the spinal cord.[1]
This sensory information travels along afferent nerve fibers in an afferent or sensory nerve, to the brain via the spinal cord. The stimulus can come from extoreceptors outside the body, for example light and sound, or from interoreceptors inside the body, for example blood pressure or the sense of body position.
Different types of sensory neurons have different sensory receptors that respond to different kinds of stimuli.

Types and function[edit]
External[edit]
Smell[edit]
The sensory neurons involved in smell are called olfactory receptor neurons. These receptor neurons contain receptors, called olfactory receptors, that are activated by the odor molecules in the air. The perception of these odor molecules is called a scent.
Taste[edit]
Similarly to olfactory receptor neurons, taste receptors (gustatory receptors) in taste buds interact with chemicals in food to produce an action potential.
Vision[edit]
Photoreceptor cells are capable of phototransduction, a process which converts light (electromagnetic radiation) into electrical signals. These signals are refined and controlled by the interactions with other types of neurons in the retina.
The five basic classes of neurons within the retina are photoreceptor cells, bipolar cells, ganglion cells, horizontal cells, and amacrine cells.
The basic circuitry of the retina incorporates a three-neuron chain consisting of the photoreceptor (either a rod or cone), bipolar cell, and the ganglion cell.
The first action potential occurs in the retinal ganglion cell. This pathway is the most direct way for transmitting visual information to the brain.
There are three primary types of photoreceptors: Cones are photoreceptors that respond significantly to color. In humans the three different types of cones correspond with a primary response to short wavelength (blue), medium wavelength (green), and long wavelength (yellow/red).[2] Rods are photoreceptors that are very sensitive to the intensity of light, allowing for vision in dim lighting. The concentrations and ratio of rods to cones is strongly correlated with whether an animal is diurnal or nocturnal. In humans, rods outnumber cones by approximately 20:1, while in nocturnal animals, such as the tawny owl, the ratio is closer to 1000:1.[2] Retinal ganglion cells are involved in the sympathetic response. Of the ~1.3 million ganglion cells present in the retina, 1-2% are believed to be photosensitive.[3]
Problems and decay of sensory neurons associated with vision lead to disorders such as:
Macular degeneration – degeneration of the central visual field due to either cellular debris or blood vessels accumulating between the retina and the choroid, thereby disturbing and/or destroying the complex interplay of neurons that are present there.[4]
Glaucoma – loss of retinal ganglion cells which causes some loss of vision to blindness.[5]
Diabetic retinopathy – poor blood sugar control due to diabetes damages the tiny blood vessels in the retina.[6]
Auditory[edit]
The auditory system is responsible for converting pressure waves generated by vibrating air molecules or sound into signals that can be interpreted by the brain.
This mechanoelectrical transduction is mediated with hair cells within the ear. Depending on the movement, the hair cell can either hyperpolarize or depolarize. When the movement is towards the tallest stereocilia, the Na+ cation channels open allowing Na+ to flow into cell and the resulting depolarization causes the Ca++ channels to open, thus releasing its neurotransmitter into the afferent auditory nerve. There are two types of hair cells: inner and outer. The inner hair cells are the sensory receptors .[7]
Problems with sensory neurons associated with the auditory system leads to disorders such as:
Auditory processing disorder – Auditory information in the brain is processed in an abnormal way. Patients with auditory processing disorder can usually gain the information normally, but their brain cannot process it properly, leading to hearing disability.[8]
Auditory verbal agnosia – Comprehension of speech is lost but hearing, speaking, reading, and writing ability is retained. This is caused by damage to the posterior superior temporal lobes, again not allowing the brain to process auditory input correctly.[9]
Temperature[edit]
Thermoreceptors are sensory receptors, which respond to varying [temperature]s. While the mechanisms through which these receptors operate is unclear, recent discoveries have shown that mammals have at least two distinct types of thermoreceptors.[10] The bulboid corpuscle, is a cutaneous receptor a cold-sensitive receptor, that detects cold temperatures. The other type is a warmth-sensitive receptor.
Mechanoreceptors[edit]
Mechanoreceptors are sensory receptors which respond to mechanical forces, such as pressure or distortion.[11]
Specialized sensory receptor cells called mechanoreceptors often encapsulate afferent fibers to help tune the afferent fibers to the different types of somatic stimulation. Mechanoreceptors also help lower thresholds for action potential generation in afferent fibers and thus make them more likely to fire in the presence of sensory stimulation.[12]
Some types of mechanoreceptors fire action potentials when their membranes are physically stretched.
Proprioceptors are another type of mechanoreceptors which literally means "receptors for self". These receptors provide spatial information about limbs and other body parts.[13]
Nociceptors are responsible for processing pain and temperature changes. The burning pain and irritation experienced after eating a chili pepper (due to its main ingredient, capsaicin), the cold sensation experienced after ingesting a chemical such as menthol or icillin, as well as the common sensation of pain are all a result of neurons with these receptors.[14]
Problems with mechanoreceptors lead to disorders such as:
Neuropathic pain - a severe pain condition resulting from a damaged sensory nerve [14]
Hyperalgesia - an increased sensitivity to pain caused by sensory ion channel, TRPM8, which is typically responds to temperatures between 23 and 26 degrees, and provides the cooling sensation associated with menthol and icillin [14]
Phantom limb syndrome - a sensory system disorder where pain or movement is experienced in a limb that does not exist [15]
Internal[edit]
Internal receptors that respond to changes inside the body are known as interoceptors.
Blood[edit]
The aortic bodies and carotid bodies contain clusters of glomus cells – peripheral chemoreceptors that detect changes in chemical properties in the blood such as oxygen concentration.[16] These receptors are polymodal responding to a number of different stimuli.
Nociceptors[edit]
Nociceptors respond to potentially damaging stimuli by sending signals to the spinal cord and brain. This process, called nociception, usually causes the perception of pain.[17] They are found in internal organs as well as on the surface of the body. Nociceptors detect different kinds of damaging stimuli or actual damage. Those that only respond when tissues are damaged are known as "sleeping" or "silent" nociceptors.
Thermal nociceptors are activated by noxious heat or cold at various temperatures.
Mechanical nociceptors respond to excess pressure or mechanical deformation.
Chemical nociceptors respond to a wide variety of chemicals, some of which are signs of tissue damage. They are involved in the detection of some spices in food.
Connection with the central nervous system[edit]
Information coming from the sensory neurons in the head enters the central nervous system (CNS) through cranial nerves. Information from the sensory neurons below the head enters the spinal cord and passes towards the brain through the 31 spinal nerves.[18] The sensory information traveling through the spinal cord follows well-defined pathways. The nervous system codes the differences among the sensations in terms of which cells are active.
Classification[edit]
Adequate stimulus[edit]
A sensory receptor's adequate stimulus is the stimulus modality for which it possesses the adequate sensory transduction apparatus. Adequate stimulus can be used to classify sensory receptors:
Baroreceptors respond to pressure in blood vessels
Chemoreceptors respond to chemical stimuli
Electromagnetic radiation receptors respond to electromagnetic radiation[19]
Infrared receptors respond to infrared radiation
Photoreceptors respond to visible light
Ultraviolet receptors respond to ultraviolet radiation[citation needed]
Electroreceptors respond to electric fields
Ampullae of Lorenzini respond to electric fields, salinity, and to temperature, but function primarily as electroreceptors
Hydroreceptors respond to changes in humidity
Magnetoreceptors respond to magnetic fields
Mechanoreceptors respond to mechanical stress or mechanical strain
Nociceptors respond to damage, or threat of damage, to body tissues, leading (often but not always) to pain perception
Osmoreceptors respond to the osmolarity of fluids (such as in the hypothalamus)
Proprioceptors provide the sense of position
Thermoreceptors respond to temperature, either heat, cold or both
Location[edit]
Sensory receptors can be classified by location:
Cutaneous receptors are sensory receptors found in the dermis or epidermis.[20]
Muscle spindles contain mechanoreceptors that detect stretch in muscles.
Morphology[edit]
Somatic sensory receptors near the surface of the skin can usually be divided into two groups based on morphology:
Free nerve endings characterize the nociceptors and thermoreceptors and are called thus because the terminal branches of the neuron are unmyelinated and spread throughout the dermis and epidermis.
Encapsulated receptors consist of the remaining types of cutaneous receptors. Encapsulation exists for specialized functioning.
Rate of adaptation[edit]
A tonic receptor is a sensory receptor that adapts slowly to a stimulus[21] and continues to produce action potentials over the duration of the stimulus.[22] In this way it conveys information about the duration of the stimulus. Some tonic receptors are permanently active and indicate a background level. Examples of such tonic receptors are pain receptors, joint capsule, and muscle spindle.[23]
A phasic receptor is a sensory receptor that adapts rapidly to a stimulus. The response of the cell diminishes very quickly and then stops.[24]It does not provide information on the duration of the stimulus;[22] instead some of them convey information on rapid changes in stimulus intensity and rate.[23] An example of a phasic receptor is the Pacinian corpuscle.
Drugs[edit]
There are many drugs currently on the market that are used to manipulate or treat sensory system disorders. For instance, Gabapentin is a drug that is used to treat neuropathic pain by interacting with one of the voltage-dependent calcium channels present on non-receptive neurons.[14] Some drugs may be used to combat other health problems, but can have unintended side effects on the sensory system. Ototoxic drugs are drugs which affect the cochlea through the use of a toxin like aminoglycoside antibiotics, which poison hair cells. Through the use of these toxins, the K+ pumping hair cells cease their function. Thus, the energy generated by the endocochlear potential which drives the auditory signal transduction process is lost, leading to hearing loss.[25]
Neuroplasticity[edit]
Ever since scientists observed cortical remapping in the brain of Taub's Silver Spring monkeys, there has been a lot of research into sensory system plasticity. Huge strides have been made in treating disorders of the sensory system. Techniques such as constraint-induced movement therapy developed by Taub have helped patients with paralyzed limbs regain use of their limbs by forcing the sensory system to grow new neural pathways.[26] Phantom limb syndrome is a sensory system disorder in which amputees perceive that their amputated limb still exists and they may still be experiencing pain in it. The mirror box developed by V.S. Ramachandran, has enabled patients with phantom limb syndrome to relieve the perception of paralyzed or painful phantom limbs. It is a simple device which uses a mirror in a box to create an illusion in which the sensory system perceives that it is seeing two hands instead of one, therefore allowing the sensory system to control the "phantom limb". By doing this, the sensory system can gradually get acclimated to the amputated limb, and thus alleviate this syndrome.[27]
Other animals[edit]
Hydrodynamic reception is a form of mechanoreception used in a range of animal species.

Power of 10
From Wikipedia, the free encyclopedia
Jump to: navigation, search
This article is about the mathematical concept. For other uses, see Power of 10 (disambiguation).
Visualisation of powers of 10 from one to 1 billion.
In mathematics, a power of 10 is any of the integer powers of the number ten; in other words, ten multiplied by itself a certain number of times (when the power is a positive integer). By definition, the number one is a power (the zeroth power) of ten. The first few non-negative powers of ten are:
1, 10, 100, 1,000, 10,000, 100,000, 1,000,000, 10,000,000. ... (sequence A011557 in the OEIS)

Positive powers[edit]
In decimal notation the nth power of ten is written as '1' followed by n zeroes. It can also be written as 10n or as 1En in E notation. See order of magnitude and orders of magnitude (numbers) for named powers of ten. There are two conventions for naming positive powers of ten, called the long and short scales. Where a power of ten has different names in the two conventions, the long scale name is shown in brackets.
The positive 10 power related to a short scale name can be determined based on its Latin name-prefix using the following formula: 10 [(prefix-number + 1) × 3]
Examples: billion = 10 [(2 + 1) × 3] = 10 9 ; octillion = 10 [(8 + 1) × 3] = 10 27

Negative powers[edit]
The sequence of powers of ten can also be extended to negative powers.
Similarly to above, the negative 10 power related to a short scale name can be determined based on its Latin name-prefix using the following formula: 10 -[(prefix-number + 1) × 3]
Examples: billionth = 10 -[(2 + 1) × 3] = 10 -9 ; quintillionth = 10 -[(5 + 1) × 3] = 10 -18

Googol[edit]
Main article: googol
The number googol is 10100. The term was coined by 9-year-old Milton Sirotta, nephew of American mathematician Edward Kasner, popularized in his 1940 book Mathematics and the Imagination, it was used to compare and illustrate very large numbers. Googolplex, a much larger power of ten (10 to the googol power, or 1010100), was also introduced in that book.
Scientific notation[edit]
Main article: Scientific notation
Scientific notation is a way of writing numbers of very large and very small sizes compactly when precision is less important.
A number written in scientific notation has a significand (sometime called a mantissa) multiplied by a power of ten.
Sometimes written in the form:
m × 10n
Or more compactly as:
10n
This is generally used to denote powers of 10. Where n is positive, this indicates the number zeros after the number, and where the n is negative, this indicates the number of decimal places before the number.
As an example:
105 = 100,000[1]
10−5 = 0.00001[2]
The notation of mEn, known as E notation, is used in computer programming, spreadsheets and databases, but is not used in scientific papers.

Powers of Ten (1977). Nine-minute film. US Public Broadcasting Service (PBS), made by Charles and Ray Eames. "An adventure in magnitudes. Starting at a picnic by the lakeside in Chicago, this film transports the viewer to the outer edges of the universe. Every ten seconds we view the starting point from ten times farther out until our own galaxy is visible only as a speck of light among many others. Returning to Earth with breathtaking speed, we move inward - into the hand of the sleeping picnicker - with ten times more magnification every ten seconds. Our journey ends inside a proton of a carbon atom within a DNA molecule in a white blood cell."

I Don't Know Why (I Just Do)
From Wikipedia, the free encyclopedia
Jump to: navigation, search
"I Don't Know Why (I Just Do)" is a 1931 popular song.
The music was written by Fred E. Ahlert, the lyrics by Roy Turk. The song was published in 1931. It had three periods of great popularity: in 1931, right after its publication; in 1946; and in 1961[1] into 1962.
In 1931, the biggest-selling version was either by Russ Columbo[1] or by Wayne King;[2] both versions and recordings by Benny Krueger's orchestra (with a vocal by Smith Ballew) and by Kate Smith all had significant popularity.[1]
In 1946, three versions, by Tommy Dorsey's orchestra (with a vocal by Stuart Foster), by Frank Sinatra, and by Skinnay Ennis, all contended for popularity.[1]
In 1961, a US hit recording was issued by Linda Scott. It reached a peak position #12 in 8 weeks on the Billboard chart;[3][4] in early 1962, Eden Kane reached the British Top 10 with his version.
The song has been recorded by many artists (ranging from country-blues legends like Moon Mullican and Jerry Lee Lewis to Dean Martin) and is now a standard.
Recorded versions[edit]
The Andrews Sisters and Vic Schoen's orchestra (recorded May 8, 1946, released by Decca Records as catalog number 18899A, with the flip side "Azusa"[5])
The Aristocrats (recorded September 1, 1931, released by Romeo Records as catalog number 1711, with the flip side "Let's Drift Away on Dreamer's Bay"[6])
