New paper: Neural entrainment to speech in early stage Schizophrenia
My latest paper accepted in Neuroimage: Clinical journal aimed to assess whether neural entrainment to speech is reduced in early state psychosis.
Summary: Language processing impairments in Schizophrenia are well known. We tested whether entrainment of neural oscillations to speech are impaired in subjects at risk of developing psychosis. To investigate this possibility, we employed Magnetoencephalography to establish whether theta band neural entrainment is impaired during story listening in participants at Clinical High Risk for psychosis and First Episode Psychosis Patients. We found theta band responses from left primary auditory cortex were less entrained during speech tracking in the clinical at-risk group, suggesting that neural entrainment during language processing could help in the early detection and diagnosis of Schizophrenia.

Published by Glasgow Natural History Society
My two games on trees entitled Tree-ID (a hangman game of identifying trees from its bark, buds and leaves) and Treeple (N.Y.Times style visual connections game on the images of barks, buds, and leaves) were published in the quarterly newsletter of Glasgow Natural History Society in Aug 2024 edition.
Summer School on ‘Brain Disorders Research’
I was selected to attend the 14th annual Summer School on ‘Brain Disorders Research’ organized by Centre for Neuropsychiatric Genetics and Genomics (CNGG), Cardiff University. The 4 days of summer school held on July 8-11, 2024 in Cardiff, Wales covered topics relating to genetics, genomics and neuroimaging of psychiatric and neurological disorders. I am grateful to CNGG for organizing such an excellent event and giving me an opportunity to participate in it since I learnt so much about such varied topics. I hope to take the learnings to help me further my research.
My interview on Clyde Samvada
The South Indian Cultural Centre of Scotland based out of the Hindu Temple of Scotland at Rutherglen hosts 'Clyde Samvada' - a weekly video podcast where they interview people who are subject matter experts or folks who work on topics connected to Indian culture.
On their 33rd episode released recently, they interviewed me to know the work done by iSeek in the form of Indic game development.

Winner of Maths Inside 2023 photo competition
I won a prize in the adult level for my photo submission entitled "Hollow Mask Illusion" under "the 'why' of shapes" category in the Maths Inside 2023 photo competition that aims to popularize scientific thinking in the general public.
My submission discusses why people do not perceive the obverse side of a mask as a concave face but as a regular face instead. This illusion is robust in general and everyone can be surprised at this trick on the brain unless they suffer from Schizophrenia.
New paper: MMN in early stage Schizophrenia
My latest paper published in Biological Psychiatry: CNNi journal aimed to assess whether Mismatch Negativity (MMN) is reduced in early state psychosis.
Summary: MMN is an event-related potential that occurs when repetitive sounds are interrupted by an occasional sound that differs in frequency or duration. Many studies have shown that patients with schizophrenia are impaired in this process. Moreover, there is evidence that MMN-deficits may be present in early-stage psychosis. To investigate this possibility, we employed Magnetoencephalography to establish whether MMN-responses are impaired in participants at Clinical High Risk for psychosis and First Episode Psychosis Patients. Contrary to our hypothesis, MMN-responses were intact, suggesting that MMN may not constitute a biomarker for early detection and diagnosis of psychosis.

New paper: EEG on Figure-Ground
My latest paper published in Hearing Research journal aimed to assess potential clinical electroencephalographic (EEG) measures of central auditory grouping (stochastic figure-ground test) and speech-in-noise perception (speech-in-babble test) with and without relevant tasks.
We convey that the brain response to listening in noisy situations can be studied without using speech and in the absence of a relevant task.

New paper: Time Window
My latest paper published in Cerebral Cortex journal aimed to identify the cortical organisation of analysis window in primates. A comparative study of this anatomical organisation of time window processing revealed interesting similarities and differences between humans and non-human primates.
New paper: Auditory Object
My latest paper demonstrates how the brain detects the emergence of a new sound in an ongoing acoustic scene.
https://onlinelibrary.wiley.com/doi/10.1111/ejn.15471
Executive Summary:
Our brain can identify any new sound as it appears, separate it from other sounds and represent it as a distinct object in our mind. Since sounds may contain multiple components that vary in frequency and time, this process requires a mechanism that monitors the statistics of the frequency-time space. This work employs artificial sounds and records neuromagnetic signals to demonstrate a specific mechanism in auditory cortex that enables the brain to detect changes in spectro-temporal coherence.
New paper: Misophonia
My latest paper on functional connectivity in fMRI data acquired from Misophonia sufferers while at rest and when presented with sounds is published in the Journal of Neuroscience. We argue that Misophonia is not a disorder of sound emotion processing but it is a result of hyper mirroring by a part of the motor cortex involved in producing these trigger sounds.

STEM for Britain 2021
On March 1st 2021, I presented my work to the Houses of UK Parliament as a finalist of the STEM for Britain 2021 contest. My work entitled "A monkey model of auditory scene analysis: How does the brain solve the 'cocktail party problem'?" was presented in the Biological and Biomedical Sciences category.
Here is my presentation:

New paper: Cocktail party effect
In my paper, published in Nature Scientific Reports, I explored whether monkeys are a good model of human brain mechanisms underlying auditory segregation colloquially known as the cocktail party effect. I show that monkeys recruit similar regions of the auditory brain as humans to segregate overlapping sounds. So I propose that monkeys are a good model to understand how single neurons accomplish separation of sounds that overlap during auditory scene analysis.
Thesis Defended
On October 25th 2018, I successfully defended my Neuroscience PhD thesis titled "A primate model of human cortical analysis of auditory objects".
Pradeep_Dheerendra-Thesis.pdfNew paper: Bird brain
In my new paper published in European Journal of Neuroscience, we investigated bird brain to confirm whether gamma oscillations exist in their hippocampus - a part of the brain that facilitates spatial memory which is known to be excellent in birds viz. seasonal migration, homing, food burial and retrieval etc. We employed invitro electrophysiology (i.e. record electrical activity from brain slices which have been artificially kept alive for few hours) and neuropharmacology (selectively bathe the brain slices in specific neurochemicals to elicit an electrical response) to address this question. We found gamma oscillations in juvenile chicken hippocampus, which were elicited by chemicals that activate cholinergic receptors (agonists). This is unlike in adult mammals where both cholinergic and glutamatergic mechanisms are known to exist. The goal of this line of work is to identify any similarities and differences in the neural circuitry generating gamma rhythms in birds and mammals that can help us identify the evolutionarily conserved and divergent aspect of rhythm generation in the brain.

New paper: Auditory Motion
In my new paper published in PLOS Biology, we investigated the brain mechanisms underlying auditory motion processing in the primate brain. We address an important question: Is auditory motion perception deduced from processing individual static sounds, or are there mechanisms in the auditory domain dedicated to detecting motion? We find specific auditory motion detectors located in the auditory cortex of primates located near visual motion detectors suggesting coordination between these areas to achieve limb and eye movement.
