Central Nervous System
Memory formation process in the CNS involves all except (AIPG 2007)
|A||It involves change in neurotransmitter release at the synapse.|
|B||Increase in no. of synapses and dendrites|
|C||Recruitment of neurons and involvement of more neurons in a particular function as in somatosensory area of cortex.|
|D||Allocation of specialized nerve cells as occurs in hippocampus.|
Memory is of types
a. Short term memory
b. Long term memory
"Short term memory involves modulation of synaptic transmission by modification of pre existing proteins whereas long term memory involves formation of new synaptic connection and synthesis of new proteins"
Recruitment of neurons is called Cortical plasticity and is a established mechanism of Memory & learning. There is no concept of memory cells or specialized nerve cells and also hippocampus doesnot store memory. So the best answer is D.
