Role of Neurotransmitters on Memory and Learning

M. Sanmuga Revathi, Dr M. Parimala Fathima, Dr S. Mohan

Abstract :

The neurotransmitters responsible for the synaptic leap between ain cells are but one category of “informational substances” that carryout the process we call learning. The “informational substances” of the second, parallel system are a variety of transmitters, peptides, hormones and protein ligands. Travelling via intercellular pathways such as the bloodstream, these substances reach receptors on the outer surfaces of cells throughout the body. Some neuroscientists speculate that less than two percent of neuronal communication actually occurs at the synapses between neurons of the ain. The rest of the communication occurs through these informational substances.
