Which statement is true regarding the effects of heterosynaptic changes? A) They can happen independently of activity-driven inputs. B) They are solely due to postsynaptic receptor changes. C) They require coordinated activation of both synapses. D) They only affect the stimulated input synapses.
Understand the Problem
The question is asking about the effects of heterosynaptic changes, which refers to changes in synaptic strength or efficiency that occur due to the activity of neighboring synapses. The respondent must evaluate the statements provided to determine which one is true.
Answer
Heterosynaptic changes can happen independently of activity-driven inputs.
Heterosynaptic changes can happen independently of activity-driven inputs.
Answer for screen readers
Heterosynaptic changes can happen independently of activity-driven inputs.
More Information
Heterosynaptic plasticity involves changes at synapses that were not active during induction and can be regulated independently of the activity that initially triggers synaptic changes.
Tips
A common mistake is assuming heterosynaptic changes are only activity-driven or impacting only stimulated synapses.
