Abstract: The adult brain is quite plastic and has the capacity to reorganize neural circuitries and even behavioural strategies as a result of experience. These phenomena have been demonstrated in both animal models and human subjects. Further studies have demonstrated the importance of interventions such as environmental enrichment paradigms, exercise, nutrition etc. in enhancing behavioural and cognitive functions. We have employed various such strategies to tap the properties of brain plasticity and cognitive reserves, using a rat model of cognitive impairment produced by selective lesioning of the ventral subiculum bilaterally. The subiculum is an important structure of hippocampal formation, involved in spatial cognition and motivation. Ventral subicular lesions have produced considerable deficits in spatial learning and memory functions. Degeneration of hippocampal formation, including the subiculum, has been implicated in Alzheimer’s Disease, which features progressive impairment of cognition. The importance of appropriate strategies in accentuating plasticity events and establishing functional recovery in ventral subicular-lesioned rats has now been widely established. Our studies, carried out over a decade, have stimulated us profoundly as well as challenged our understanding of the complexities of brain–behavior relationships. Although these studies provide significant insights into cognitive reserve, the onus is on us to explore such interventions in the management of cognitive deficits in neurodegenerative disorders such as Alzheimer’s Disease.

This is to remind you that NIAS has decided to establish an inter-institution Forum for Interdisciplinary Research and Studies (FIRST), with two principal aims:
1. Invite eminent scholars from various institutes and universities in and around Bengaluru to discuss recent work (their own or of others) in various disciplines that have adopted interdisciplinary approaches. We propose that these meetings be held once a month, on the afternoon of the last Friday of each month, at NIAS
2. Build up a virtual library or an electronic archive of interdisciplinary research manuscripts and publications, where it would be possible to upload relevant papers as well as download them, of course, only for academic purposes. We envisage that this archive be housed on the NIAS website
