Activity at these sites increases their strength according to the Hebbian theory of learning. For 10 points each:
[10e] Neurotransmitters are released into what spaces between neurons? These sites have axodendritic, axosomatic, or axoaxonic types.
ANSWER: synapses [or synaptic cleft; reject “electrical synapses”]
[10m] This complex, which includes syntaxin and synaptobrevin, is responsible for mediating vesicle fusion in the presynaptic membrane. These zipper-like proteins have v- and t- types.
ANSWER: SNARE complex [or soluble NSF attachment protein receptor]
[10h] This principle states that a neuron uses the same neurotransmitter set at all of its synaptic outputs. Co-transmission, such as in striatal GABA neurons, is an exception to this rule.
ANSWER: Dale’s principle [or Dale’s law]
