Question

Spike-timing dependent plasticity with acetylcholine but no norepinephrine leads to:

a) Facilitated plasticity
b) Impaired plasticity
c) No change in plasticity
d) Irregular plasticity patterns

Answer 1

Spike-timing dependent plasticity with acetylcholine but no norepinephrine does not lead to any change in plasticity.

Step-by-step explanation:

Spike-timing dependent plasticity (STDP) is a process in the brain that involves changes in the strength of synapses based on the timing of the electrical activity in the neurons. Acetylcholine is a neurotransmitter that can modulate synaptic plasticity. Norepinephrine is another neurotransmitter that can also modulate synaptic plasticity. However, in the absence of norepinephrine, STDP with acetylcholine alone can still lead to plasticity changes.

So, the answer to your question is: c) No change in plasticity
