Behavioral Neuro

Postsynaptic Potentials:Neural integration/Autoreceptors/other synapses

TermDefinition
neural integration the interaction of the effects of excitatory and inhibitory synapses on a particular neuron.
axon hillock located at the base of the axon. If the EPSP's reach it the axon will fire
neural inhibition an inhibitory postsynaptic potential
behavioral inhibition inhibition of inhibitory neurons will make the behavior more likely to happen. Excitation of neurons that inhibit a behavior suppresses that behavior
autoreceptors located on the terminal button, regulate amount of neurotransmitter produced and released.
axoaxonic are synapses that occur on axons (do not contribute directly to neural integration)
presynaptic inhibition when the activity of the axoaxonic synapse "decreases" the release of the neurotransmitter
presynaptic facilitation when the activity of the axoaxonic synapse "increases" the release of the neurotransmitter
dendrodendritic synapses synapses between dendrites. M any very small neurons have extremely short processes and lack axons
gap junction for electrical synapses, where the membranes meet and almost touch
reuptake reentry of a released neurotransmitter back into the presynaptic cell
Enzymatic deactivation destruction of a neurotransmitter by an enzymeafter its release
hormones 1.secreted by glands and organs into extracellular fluid 2. distributed widely via bloodstream 3. can affect neurons as well as other target cells throughout the body
steroid hormones can travel into nucleus of cells
