New paper: Auditory Object

My latest paper published recently demonstrates how the brain detects the emergence of a new sound in an ongoing acoustic scene.

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.
