What structural changes occur in the neurons as a result of learning?
A) The neurons develop additional sodium ion gates to allow for faster action potentials.
B) The neurons develop additional Nodes of Ranvier and more myelination.
C) The axon terminals of presynaptic neurons grow new dendritic spines.
D) The dendrites of postsynaptic neurons grow new dendritic spines.

Question

Quizplus · Accepted Answer

Learning is associated with the growth of new dendritic spines on the dendrites of postsynaptic neurons, which increases the number of connections (synapses) between neurons. This allows for more efficient transmission of information and is a key process in the formation of new memories. Options A and B are incorrect because they pertain to changes in the structure of axons, not dendrites. Option C is incorrect because axon terminals do not typically form dendritic spines.
