Jasleen Gund (Postdoctoral Research Associate)
In the world of uncertainties and complexities all around, be it living cell or the entire universe, Jasleen chose to study the brain as a complex system that allows us to observe all the complexities. Her work profile broadly categorizes her as a computational neuroscientist. She has a biological background with Bachelors in Life sciences and Masters in Biotechnology. She has done her Ph.D. in computational neuroscience from Jawaharlal Nehru University. She has acquired experience in computational and mathematical techniques during her Ph.D. and applied this mathematical techniques to time-series data analysis in the field of neuroscience. She is always excited to study any aspect towards understanding of the brain functionality. She is currently working on the analysis of the EEG data of individuals with static and dynamic visual stimulus and their characterization with and without saliency conditions. Also, analyzing the MEG dataset of young and old individuals to decipher age -related changes in the functional brain dynamics. Apart from the research she invests her brain in poetry and listening to music. She likes to observe nature and do nature photography.
Abhishek Narvaria (Ph.D. student)
Abhishek completed his master’s degree from CBCS Allahabad University. Currently, he is working on behavioral experiments to study the relationship between top-down attention and working memory. In particular, he is interested in the theory of divergence and convergence zones in the brain. His longterm interest is to understand the neural dynamics to uncover the role of attention in memory in the human brain using EEG and fMRI.
Vanshika Singh (Ph.D. student)
Vanshika is a senior research fellow pursuing PhD in neuroscience, and finds her muse in the art of communicating science to a wider audience as a freelance science writer. Her research focuses on the causal dynamics of cortical and thalamo-cortical interactions within and between resting state functional networks and understanding the changes that occur therein with healthy aging. When not at the bench working through experiments, you’d mostly find her grooving to blues music behind her drum kit.
Azman Akhtar (Integrated Ph.d. student )
Azman did BSc in Zoology from Aligarh Muslim University. He continued to do PhD after MSc in Neuroscience from NBRC itself. Currently, he is interested in understanding the neural correlates of reading in different orthographies by multiliterates and the underlying anatomical characteristics. He is taking the help of the unique culture of North Indians to read and write two distinctly different orthographies, Hindi and Urdu, for the same language, Hindustani. His longterm interest is to understand the neural dynamics of language processing in the brain using EEG/fMRI in bilingual population.
Gargi Majumdar (Integrated Ph.d. student )
How do emotions play in our mind? Is it the puppeteer driving and directing us in most social scenarios or the other way around? These pressing questions led Gargi into the world of neuroscience after she finished her Master’s in Zoology. Ever curious about this enigmatic trait – emotions, she was amazed to find that even after all these years there exists no unanimous definition of emotion. Driven by her quest to study neuroscience of complex emotions, she is into investigating how suspense is played in human brain in the context of predictions. She is currently making people watch movies to study their emotions and looking into fMRI signals for the underlying cause. While not getting into other people’s head she can be found staring at the sky, chasing after birds or lost in the mountains.
Vinsea AV Singh (Masters student)
Perception causes interaction among the neural entities. In my master’s dissertation work, I have analyzed the pre-stimulus neural oscillations to explain the inter-individual and inter-trial variability in perception among the participants subjected to the McGurk illusion (incongruent visual and auditory syllables perceived as a completely different syllable). More precisely, I have studied the differences in the pre-stimulus electrophysiological (EEG) data between the ‘rare’ and ‘frequent’ group of perceivers of the McGurk effect. I have computed the power spectrum, global coherence, and FOOOF (Fitting Oscillations and One Over Frequency) to study the cortical dynamics in the pre-stimulus EEG signals of the participants, that were subjected to both the incongruent (McGurk- audio-/pa/, video-/ka/) and congruent (syllables /pa/, /ta/, and /ka/) AV-stimulus. The results show that there is indeed a difference in the neuronal dynamics of the two groups, suggesting that multisensory processing relies on different brain regions and that these regions have distinct developmental trajectories leading to a difference in the degree of perception at the individual level.
Priyanka Sigar (Project Assistant)

She has explored the field of Zoology as a bachelors’ student at Mumbai University followed by pursuing masters in Lifesciences (neuroscience) from Sophia Women’ College, University of Mumbai. She worked as an intern at the Foundation of Medical Research Centre, Mumbai. To get a better understanding of developmental disorders and therapies, she worked as a child counsellor and therapist at Little Pods, Mumbai. Currently, her focus is to study the dynamics of functional connectivity in the autistic brain to understand the underlying reasons for behavioral traits in Autism Spectrum Disorder. Apart from being a semi-nerd, she is also engaged in sketching, career counselling & music.
FAHD YAZIN (Project Assistant)
Contact : email@example.com
Fahd did his Bachelor of Medicine and Bachelor of Surgery- Calicut University, Kerala. He did an internship following his MBBS. After finishing medicine Fahd decided to plunge into this realm to understand the neural correlates of surprising and novel events happening in the days of our lives, and how they affect advanced aspects of cognition like Episodic Memory, Sequence learning, Imagination and Time perception. He is currently pursuing the relation between surprise and episodic sequence learning. He also loves consumer neuroscience. When his brain is not being used to research other brains, he uses it to play RPG games with friends, watch horror movies alone & teach kittens candy crush.
VIVEK SHARMA (Project assistant)

Vivek completed his bachelor’s degree in Zoology from Dyal Singh College, Delhi University. Later, he completed his master’s degree in BIochemistry from Jamia Millia Islamia, Delhi. With the motivation to learn more about signal processing and mathematical modelling, he joined Cognitive Brain Dynamics Lab, NBRC. Currently he is working on the overlap between MEG resting state and task networks on healthy ageing using Source Localization methods. He is using MEG data and python to study age-related changes in the brain.
