Chapter 24 Flashcards

amblyopia
Diminished visual acuity as a result of the failure to establish appropriate visual cortical connections in early life.
competitive interaction
The struggle among nerve cells, or nerve cell processes, for limited resources essential to survival or growth.
critical period
A restricted developmental period during which the nervous system is particularly sensitive to the effects of experience.
Hebb’s postulate
The idea that when pre- and postsynaptic neurons fire action potentials at the same time, the synaptic association between those cells strengthens. Sometimes catchily phrased as "cells that fire together wire together," the postulate provides one explanation for the formation of certain neural networks.
ocular dominance columns
The segregated termination patterns of thalamic inputs representing the two eyes in the primary visual cortex of some mammalian species.
strabismus
Developmental misalignment of the two eyes; may lead to binocular vision being compromised.
