Behavioral Neuro
Postsynaptic Potentials:Neural integration/Autoreceptors/other synapses
Term | Definition |
---|---|
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 |
