If a disease or disorder interferes with learning and memory,which of the following should the mechanism of the disease should involve?
A)changes in the concentration of ions in the extracellular fluid surrounding neurons
B)changes in myelination of axons
C)changes to the chemical structure of neurotransmitters
D)molecular and structural changes at synapses
E)structural changes to ion channels in axon

Question

Learning and memory involve the formation and strengthening of synapses between neurons. Therefore, any disease or disorder that interferes with this process is likely to involve molecular and structural changes at synapses. Other options such as changes in the concentration of ions or chemical structure of neurotransmitters could certainly affect neuronal function, but they would not necessarily disrupt learning and memory specifically. Axon myelination and ion channel structure are also important for proper neuronal function, but they are not directly involved in the formation and maintenance of synapses necessary for learning and memory.
