Summary Introduction

To discuss:

The neural mechanism thought to be involved in these different forms of memory and in forgetting.

Introduction:

The “memory cells “in the brain are not the storage site, for what we learn and remember. There is no neuron which is assigned to remember your mobile number. The memory trace is the pathway through the brain for the physical basis of memory. The number of synapses is not fixed, depending on the experience synapses can be deleted or added or even modified. In other words synapses can be deleted or created within 1 or 2 hours. The capability of the synapse to change is known as synaptic plasticity. So learning involves the modification of the synapses of existing neurons and not the population of neurons.
