Decoding Individual and Shared Experiences of Media Perception Using CNN Architectures

Johri, Riddhi (author), Pandey, Pankaj (author), Miyapuram, Krishna Prasad (author), Lomas, J.D. (author)

The brain is an incredibly complex organ capable of perceiving and interpreting a wide range of stimuli. Depending on individual brain chemistry and wiring, different people decipher the same stimuli differently, conditioned by their life experiences and environment. This study’s objective is to decode how the CNN models capture and learn...

Experimental and numerical study of Conoscopic Interferometry sensitivity for optimal acoustic pulse detection in ultrafast acoustics

Robin, M.P. (author), Guis, R.H. (author), Arabul, Mustafa Umit (author), Zhou, Zili (author), Pandey, Nitesh (author), Verbiest, G.J. (author)

Conoscopic interferometry is a promising detection technique for ultrafast acoustics. By focusing a probe beam through a birefringent crystal before passing it through a polarizer, conoscopic interferences sculpt the spatial profile of the beam. The use of these patterns for acoustic wave detection revealed a higher detection sensitivity over...

Stronger correlation of music features with brain signals predicts increased levels of enjoyment

Pandey, Pankaj (author), Bedmutha, Poorva Satish (author), Miyapuram, Krishna Prasad (author), Lomas, J.D. (author)

Music recommendation systems struggle with predicting the aesthetic responses of listeners based solely on acoustic characteristics, which are dependent on the listener's perception. This research correlates acoustic music features with brain responses to report the neural aesthetic hypothesis that the intensity of an aesthetic experience can...

Classifying EEG Signals of Mind-Wandering Across Different Styles of Meditation

Chaudhary, Shivam (author), Pandey, Pankaj (author), Miyapuram, Krishna Prasad (author), Lomas, J.D. (author)

In the modern world, it is easy to get lost in thought, partly because of the vast knowledge available at our fingertips via smartphones that divide our cognitive resources and partly because of our intrinsic thoughts. In this work, we aim to find the differences in the neural signatures of mind-wandering and meditation that are common across...

EEG Spectral Correlates of Rapid and Deep Slow Breathing States and classification using ML

Patnaik, Siddesh (author), Pandey, Pankaj (author), Arun, Ishita (author), Yadav, Goldy (author), Miyapuram, Krishna Prasad (author), Lomas, J.D. (author)

One interpretation of breathing exercise is to enforce mind-body harmony, when someone feels well and healthy, different organs of our body function harmoniously. One dysfunctional organ may disturb the resonating mechanism across multiple organs. There are different breathing techniques, and recent scientific evidence encourages...

Music identification using brain responses to initial snippets

Pandey, Pankaj (author), Sharma, Gulshan (author), Miyapuram, Krishna P. (author), Subramanian, Ramanathan (author), Lomas, J.D. (author)

Naturalistic music typically contains repetitive musical patterns that are present throughout the song. These patterns form a signature, enabling effortless song recognition. We investigate whether neural responses corresponding to these repetitive patterns also serve as a signature, enabling recognition of later song segments on learning...
