In a fantastic new work, graduate student Indra Nair demonstarted using classic double rotation experiment with reward flavour-landmark cue conflict while processing memory that Hippocampus maintains a flexible and coherent map while competeing between two modalities. This is now published in Frontiers in Neural Circuits.

Hippocampus maintains a flexible and coherent map under reward flavor-landmark cue conflict.” Nair, Indrajith R., and Dipanjan Roy. Frontiers Neural Circuits (2022)

More recent works got published in various forum. Mainly, we are getting increasingly excited about understanding preservation of neural sysnchronization at various frequencies of interest with healthy aging and stability of the structural core. This may have huge implication for brain functions and behavior in the face of continuous changes in White matter structures in various areas. This is now accepted Communication Biology.

Preservation of neural synchrony at Peak Alpha Frequency via global synaptic coupling compensates for white matter structural decline over adult lifespan Anagh Pathak, Vivek Sharma, Dipanjan Roy, Arpan Banerjee doi: https://doi.org/10.1101/2021.10.24.465613 (2022) Communication Biology (accepted in May)

In a separate study, we have shown that a large part of age-associated alterations of dynamic configurations and repertoire in the whole brain resting state is governed by the stability of sensorimotor network.
