Post stimulus time histogram
|
|
Post stimulus time histogram A method for examining cell response to a particular stimulus. The time after stimulus onset is divided into a number of bins. The stimulus is then presented repeatedly and the count in each bin increased each time the cell fires during that time bin.
RELATED TERMS--------------------------------------
Cell
Fundamental structural unit of all life. The cell consists primarily of an outer plasma membrane, which separates it from the environment; the genetic material (DNA), which encodes heritable information for the maintainance of life; and the cytoplasm, a heterogeneous assemblage of ions, molecules, and fluid.
SIMILAR TERMS--------------------------------------
Post
Thin metal rod inserted into the root of a tooth after root canal therapy; provides retention for a "coping" that replaces lost tooth structure and retains crown.
Post partum
Post partum refers to the period after childbirth.
Post-core
Post and buildup to replace lost tooth structure and retain crown.
Post-crown
Single structure that combines post-core and crown.
Post-traumatic stress disorder (PTSD)
A syndrome caused by re-experiencing traumatic events while being unaware of or unresponsive to current events or, in other words, a "flashback." A child may experience sleeping problems, nightmares, intrusive thoughts, have difficulty concentrating, self-destructive behavior, hyperactivity or anxiety/panic disorder. Therapy is crucial in managing PTSD.
Postcholecystectomy syndrome
A condition that occurs after gallbladder removal. The muscle between the gallbladder and the small intestine does not work properly, causing pain, nausea, and indigestion. Also called biliary dyskinesia.
Posterior
At or toward the back.
Posterior parietal cortex
Concerned with the perception of the spatial relations among objects.
Postgastrectomy syndrome
A condition that occurs after an operation to remove the stomach (gastrectomy). See also dumping syndrome.
Postmarketing surveillance
ongoing safety monitoring of marketed drugs. See Phase 4 studies, Phase 5 studies.
Postmature
An infant born at 42 weeks or more is considered postmature. As withprematurity, being postmature can lead to complications; the baby may belarger and less able to pass through the birth canal or the placenta may nolonger be able to provide adequate oxygen or nutrition.
Postnatal care
Medical care for both newborn and mother during the first 6 weeks after birth.
Postnatal Depression
Depression in women occurring usually within four weeks after the delivery of a child. The degree of depression ranges from mild transient depression to neurotic or psychotic depressive disorders.
Postoperative
After surgery.
Postpartum
After childbirth.
Postpartum depression
More severe than the more common and milder baby blues, postpartumdepression is characterized by sadness, impatience, restlessness, and inability to care for the baby.
Postprandial
Occurring after a meal. Example: Blood taken 1-2 hours after eating to see the amount of glucose in the blood would be called a postprandial blood glucose test.
Postural Orthostatic Tachycardia Syndrome (POTS) (Neurocardiogenic Syncope, Dysautonomia)
Dysfunction of the autonomic nervous syndrome. Causes symptoms of fatigue, dizziness, increased heart rate, and other symptoms. See syncope.
Postural tremor
A tremor of a limb that increases when the limb is stretched.
Posturography
A force platform that evaluates somatosensory and visual influences on posture and equilibrium.
Postvagotomy stasis
Delayed stomach emptying; occurs after surgery on the vagus nerve.
PREVIOUS AND NEXT TERMS--------------------------------------
Pigment epithelium
Cells lining the back of the eye containing melanin which resynthesize photopigment for photoreceptors.
Pointspread
A measure of optical blur produced by natural imperfections of the lens of the eye. The response to a point of light produces a certain amount of blur, the amount of this blurring is known as the pointspread.
Poles (of optic flow field)
The two points in the optic flow field surrounding an observer moving through the environment at which there is no flow of optic texture. One is the point toward which the observer is moving and the other is the point away from which the observer is moving.
Pool hypothesis
Hypothesis for the mechanism for stereopsis. Suggests the visual system contains three pools, one for crossed disparities, one for uncrossed disparities and one for non-zero disparities. A particular depth is signaled by the relative activity of crossed and uncrossed pools rather than by a sharply tuned neuron coding a particular depth.
Pop-Out
Target items in a visual search that have features which allow them to be detected quickly regarless of the nummber of distractors presents are said to "pop-out".
Post stimulus time histogram
Prelunate cortex
Area V4 in rhesus monkey brain.
Pretectal area
Midbrain area just rostral to the superior colliculus. Receives input from the optic tract. Projects bilaterally to the preganglionic parasympathetic neurons of the accessory oculomotor nucleus. Mediates pupillary light reflexes.
Principle of univariance
The absorbtion of a long wavelength (low frequency, low energy) quantum has the same effect on a receptor as the absorbtion of a short wavelength (high frequency, high energy) quantum. It is the probability of absorption that changes photoreceptor sensitivity.
Prosopagnosia
A loss of the ability to identify members of complex categories such as faces.
Psychophysical function
A plot showing the variation in threshold (e.g. the dimmest light required for response) with some stimulus dimension (e.g. wavelength).
