NITI Aayog hosted a brainstorming session with the Directors of IISERs on ‘Catalysing R&D in IISERs in India’, chaired by Prof. Gobardhan Das, Member, NITI Aayog. The session reviewed the research and innovation landscape of IISERs, including key findings from Clarivate Analytics and institutional perspectives on emerging opportunities and challenges.
With the participation of the Secretary, Higher Education, discussions explored the proposed IISER Council, strengthening faculty and research capacity, and rationalising PhD fees to make doctoral education more attractive and comparable with leading premier institutions.
The deliberations emphasised strengthening IISERs as centres of excellence in science, research and innovation, while fostering an enabling environment to attract and retain high-quality faculty, researchers and doctoral talent. The need to promote translational research and convert scientific discoveries into technologies and solutions with real-world impact was also highlighted.
The session reaffirmed the commitment to a stronger, coordinated and globally competitive R&D ecosystem, with IISERs playing a greater role in India’s scientific and technological advancement.

The Principal Scientific Adviser to the Government of India, @AjaySoodIISc, joined the 6th Convocation of the Indian Institute of Science Education and Research, @IISER_BERHAMPUR, as the Chief Guest. The ceremony was attended by Shri Satyabrata Dey, Chairman, Board of Governors; Prof. @arvindnatu, Former Chairman and Member, Standing Committee; Prof. Ashok Ganguly, Director; and Shri P. K. Ray, Registrar, from IISER, Berhampur.
In his address, Prof. Sood underscored the importance of nurturing scientists who are not only researchers but also entrepreneurs, policy thinkers, and educators. He encouraged IISER Berhampur to strengthen interdisciplinary learning that prepares graduates for leadership across science and society.
Highlighting India's rapidly evolving innovation ecosystem, Prof. Sood applauded Skyroot Aerospace's successful Vikram-1 mission as a landmark achievement reflecting the capabilities of India's young innovators. He also commended the outstanding performance of Indian students at the 2026 International Science Olympiads as evidence of the country's growing scientific talent.
Speaking on the future of research, he emphasized the convergence of artificial intelligence, quantum computing, biotechnology, and advanced materials, noting that while AI can extend human capabilities, human intelligence must continue to provide ethical judgement, creativity, and purpose.
Prof. Sood also highlighted the Rural Technology Action Group (RuTAG) Smart Village Centres, citing initiatives such as the Gaushala Model and the 'Weed to Wealth' programme as examples of science driving sustainable livelihoods and inclusive development.
Concluding his address, Prof. Sood urged the graduating students to uphold IISER Berhampur's values of academic excellence, interdisciplinarity, diversity, development, and societal outreach. Emphasizing the "S-LIFE" framework, Prof. Sood called for embedding science into everyday life by promoting hands-on laboratories, integrating research with learning, celebrating science through cultural engagement, and leveraging digital platforms to foster scientific temper.

Indeed, a scientifically encouraging moment!! Bringing science to all, and for a purpose is humbling. Kudos to you Niraj @nirajgupta02 for your hard work. Deep regards to our institution @IISER_BERHAMPUR for the support. Thanks to the Scientific Editorial members of The Hindu. White matter connectivity and its integrity seems to be a really important brain event in the aging trajectory.
Well… this happened.
Our recent research on brain vascular and white matter changes with aging just got covered by The Hindu!
White matter isn’t just “wiring.” It reflects vascular health, resilience & biological ageing.

Parkinson’s as a Somato-Cognitive Action Network Disorder? A New Brain Circuit Model Emerges. Somato-cognitive refers to how the body and brain work together by integrating movement, motivation and internal body states in order to guide action. Ren, Zhang Dosenbach, Liu and colleagues describe in a new paper that just dropped in Nature how Parkinson’s disease may be better understood, not just as a movement disorder, but as a disorder of the Somato-Cognitive Action Network (SCAN). The team leveraged a massive multimodal dataset across six interventions to show how SCAN hyperconnectivity might explain both motor and non-motor symptoms and could guide future neuromodulation treatments.
Key Points:
– The SCAN links motor, cognitive, autonomic and emotional systems, and is more tightly connected to PD circuits than traditional motor-only areas.
– Folks w/ Parkinson’s showed hyperconnectivity between the SCAN and key subcortical structures (e.g., substantia nigra, STN, GPi), a pattern not seen in other movement disorders.
– Successful therapies like DBS, TMS, focused ultrasound, and levodopa reduced the SCAN to subcortex hyperconnectivity.
My take: This paper opens the door to rethinking Parkinson’s as a disorder of action readiness and integration, not just movement execution. This is a big step forward for brain network science in Parkinson's.
Here are 5 points that resonated w/ me:
1- Parkinson’s may be better framed as a whole-body network disorder rooted in the SCAN, not just a hand or foot movement issue.
2- Brain imaging showed that the subthalamic nucleus and other DBS targets are functionally linked to the SCAN, not just to movement effectors.
3- Reducing SCAN hyperconnectivity through neuromodulation or dopamine led to better motor outcomes.
4- Targeting cortical SCAN regions w/ repetitive transcranial magnetic stimulation (rTMS) doubled the benefit as compared to traditional motor cortex stimulation.
5- Future neuromodulation strategies have the potential to personalize therapy by matching treatment to SCAN hubs, rather than single motor targets.

Today we completed Neurobiology and biochemistry at @IISER_BERHAMPUR this courses enriched my understanding to next level and big thank to @iamvivekt sir (enthusiasm ,the energy) it was great learning Phineas Gage, the legendary railway worker (iykyk) happy faces.
Had a wonderful experience introducing Neurobiology as part of the BS101 course @IISER_BERHAMPUR . The new students, despite their diverse academic backgrounds, were highly attentive and curious. Their enthusiasm and the insightful post-class questions made the session truly rewarding. Loved the energy!

Adult human brains have between 86-100 billion neurons and every single one is unique - like snowflakes! ❄️
In this 3D rendering by our #ElectronMicroscopy team, we see 3 different shapes incl. (from left to right) a basket cell, tufted excitatory cell, and a Martinotti cell.
Same pinch Niraj; Equally excited. In this study, using multiple aging cohorts- including our @IISER_BERHAMPUR aging cohort- we demonstrate that periventricular white matter hyperintensity (PVWMH) volume increases nearly twice as fast with advancing age, with a clear inflection around 61 years. We identified that a PVWMH burden exceeding 2.3 mL, independent of chronological age, is associated with selective deficits in executive, attentional, and semantic cognitive domains, along with widespread cortical and subcortical atrophy involving the nucleus accumbens, rostral middle frontal, pre/postcentral gyri, lingual gyrus, and cerebral cortex.
We emphasize that we age differently because we accumulate PVWMH differently-and once this burden crosses a critical threshold, it rewires the neuroanatomic and cognitive trajectories of aging. academic.oup.com/cercor/arti… Congratulations Niraj and Neha.
Thrilled to announce that our paper entitled "Brain aging and cognitive decline accelerate beyond a threshold of periventricular white matter hyperintensity" is now published. Read it at:
