Prelay
Prelay is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): troglitazone.
Prelone
Prelone is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): prednisolone.
Preludin
Preludin is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): phenmetrazine hydrochloride.
PREVIOUS AND NEXT TERMS--------------------------------------
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
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.
Prelunate cortex
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).
Posterior parietal cortex
Concerned with the perception of the spatial relations among objects.
