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

Question

Quizplus · Accepted Answer

Molecular and structural changes at synapses are crucial for learning and memory. Synaptic plasticity, which refers to the ability of synapses to change their strength and connectivity, is the cellular basis of learning and memory. Additionally, disorders such as Alzheimer's disease and Parkinson's disease are associated with synaptic dysfunction and loss, which contribute to cognitive impairments such as memory loss. Therefore, if a disease or disorder interferes with learning and memory, it is likely that the mechanism of the disease involves molecular and structural changes at synapses.
