Where in the nervous system are memories stored?
A
sensory neurons.
B
spinal cord.
C
peripheral nervous system.
D
brain.
Explanation: 

Detailed explanation-1: -For explicit memories – which are about events that happened to you (episodic), as well as general facts and information (semantic) – there are three important areas of the brain: the hippocampus, the neocortex and the amygdala. Implicit memories, such as motor memories, rely on the basal ganglia and cerebellum.

Detailed explanation-2: -The brain stores memories by changing how neurons talk to each other. When one neuron fires an actional potential, another neuron activates. Over time, this connection gets stronger. Scientists can watch this play out in real time by stimulating and recording slices of brain tissue.

Detailed explanation-3: -Memories are stored by changing the connections between neurons. A five-year-old child will activate a certain group of neurons (Ensemble A); whereas adults will activate a different ensemble (Ensemble A’) with the same stimulus.

Detailed explanation-4: -When a memory is created, information flows from the cortex, the part of the brain rich in nerve cells, to the hippocampus, the central switching point for memories in the brain.
