Term
neural integration
Definition
info processing w/in Nervous system; includes decision making and memory mechanisms
Term
EPSP response
Definition
excitatory as NA+ enters during depolarization
Term
IPSP response
Definition
inhibitory as Cl- enters during hyperpolarization
Term
3 fators determining postsynaptic response
Definition
1. neurotransmitter
2. receptor present
3. activity of cell when stimulated
Term
temporal summation
Definition
quick succession of EPSP's that reach threshold together
Term
spatial summation
Definition
several local potentials from several sourches reach threshold
Term
faciliatation
Definition
1 presynaptic neuron helps another stimulate
Term
presynaptic inhibition
Definition
1 presynaptic neuron makes it harder for another to stimulate
Term
neural coding
Definition
pattern of action potentials occuring as a result of one recruitment
Term
neuronal pool
Definition
composed of 1,000's to 1,000,000's interconnected neurons that are responsible 4 a secific function w/in the body
Term
neuronal circuit
Definition
series of neurons creating a pathway 4 neural info
Term
diverging circuit
Definition
multiple presynaptic neurons which synapse w/a single postsynaptic neuron
Term
reverberating circuit
Definition
circular neuronal pathway
Term
parallel after-discharge circuit
Definition
single neuron which stimulates several sequences of neurons which converge on a single postsynaptic neurons
Term
memory
Definition
storage and retrieval of aquired info
Term
synaptic plasticity
Definition
altering the synapses
Term
short-term memory
Definition
impulses are repeated but quickly lost
Term
long-term memory
Definition
growth of more synaptic knobs, more receptors
