27th October 2023: Professor Dipanjan Roy, Associate Professor, CBSA, AIDE School, has been elected as a fellow of National Academy of Sciences (NASI). NASI is the oldest Science Academy of India established in 1930 by a group of world-famous scientists led by Prof. Meghnad Saha (the Founder President). Prof. Roy has been bestowed with this honour for his outstanding contribution towards the study of the brain connectivity patterns in controls and subjects with neurodevelopmental disorders via neuroimaging techniques.
Two doctoral students Abhishek Narvaria and Gargi Majumdar have successfully submitted their PhD thesis from Cognitive Brain Dynamics Lab (CBDL) NBRC & IIT Jodhpur.

Senior Resrach Fellow Nisha Shastry PhD student’s recent article on the Stability of sensorimotor network sculpts the dynamic repertoire of resting state over lifespan is on the cover of recent issue of the Cerebral Cortex. You can find the article here: https://academic.oup.com/cercor/article/33/4/1246/6562686?login=true#.Y-z5z5vwY9Q.twitter
Very interesting media coverage about our recent work “Altered global modular organization of intrinsic functional connectivity in autism arises from atypical node-level processing”, which was authored by Priyanka Sigar (UCLA), Lucina Q. Uddin(UCLA), and Dipanjan Roy.” on the early alteration of atypical nodal information processing and hyper synchronization in Children with Autism and social symptom severity
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.

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.
