Identification of the possible sites of memory storage within live rodents

Different research in animal behavior demonstrate that amygdala, a heterogynous region in brain is related to sensitive response, incorporating input signals and initiating events associated to them. Impairment in this region can be responsible for emotional disorders in humans and social behavior. There are many experiments performed using rodents throughout the globe every day. Most of these experiments involve the death of rodents. These rodents are specifically kept for experiments related to immune system. The transgenic rodents have weak immune system as this system is disabled in them by manipulating the neurons and DNA associated with the immune system. Fear has been selected as a behaviour trait because it is widely considered as an attribute increasing survival and reproductive progress. This review article studies and highlights different research related to identify memory storage sites in rodents, its history, development and different procedures used for the process.
