Although we record and analyze different types of brain oscillations, our focus is on “gamma” oscillations (30-80 Hz). Our grand goal is to understand the neural mechanisms underlying high-level cognition. Gamma oscillations are modulated by...
We collected EEG data from a large cohort (350 recordings from 279 subjects) of elderly subjects (>50 years) while they viewed visual stimuli that induced gamma oscillations. This entire dataset and associated codes are available...
Meditation: Project Dhyaan Project Dhyaan: The goal of this project is to study the effect of various meditative practices on stimulus-induced gamma oscillations (30-80 Hz) recorded using electroencephalogram (EEG). EEG often shows rhythmic patterns at...
The brain can be stimulated in various ways. The first involves sensory stimulation. For example, by presenting flickering visual stimuli that produce a so-called steady-state visually evoked potential (SSVEP) response. The second involves electrical stimulation,...
The goal is to better understand the properties of brain signals using various signal-processing techniques for decoding and brain-machine interfacing applications. Decoding of the visual world from brain signals We studied how much information is...
