Biopsych Vocab Review
21
dendrites: tree-like projections from the soma that receive information
electrical gradient: a difference in the electrical charge between inside and outside of the cell
concentration gradient: difference in the concentration of ions inside and outside of the cell, energy is required
action potential: positive charge driven down the axon
polarization: membrane maintains an electrical gradient
depolarization: positive going change in cell's membrane potential, less polarization
temporal summation:several impulses from several neurons at the same time
spatial summation:impulses from several neurons at the same time
neurotropin: chemical that promotes the survival and activity of neurons
plasticity: the changing of neurons, anything not fixed
somatosensation: a family of perception specific to experiences that we have on our skin
labeled line principle: each receptor responds to a limited range of stimuli and sends a direct line to the brain
reflex: very specific type of movement that once initiated it cannot be stopped
basal ganglia: composed of the caudate nucleus, the putamen, and the globus pallidus
across fiber patterning principle: each receptor responds to a wider range of stimuli and contributes to the perception of each of them
iris: colored part of eye, band of muscles that controls the constriction and dilation of the eye
lens: bends light to focus image on light passing through the eye
frequency:speed of the sound wave, related to the pitch of the sound
fovea: point of central focus with a high density of photoreceptors
amplitude: height of the sound waves, related to the loudness of the sound
blind spot: a region of the retina with no photoreceptors
