The Neurons are the living cells which are the storage units in our brain. They are microorganisms that store the information. There are about 200 Billion Neurons in the Brain. The Neuron is comprised of Synapse. There is more than 125 Trillion Synapse in our Brain. Each synapse stores information in it.

Memory is most likely stored in distributed collections of cortical processing systems that are also involved in the perception, processing and analysis of the material being learned. In short, each part of the brain most likely contributes differently to permanent memory storage.
