Welcome to the NeurOscillations Lab

Our lab studies the neural basis of high-level cognition such as selective attention and meditation, with a focus on a brain rhythm called “gamma” (30-80 Hz), which is thought to be associated with high-level cognitive processes. We record from both humans and non-human primates using a variety of neurophysiological techniques while they are engaged in cognitive tasks. In humans, we record brain signals using electroencephalogram (EEG) from healthy people of different age groups, people with mild-cognitive impairment (MCI) or early Alzheimer’s Disease (AD), as well as long term meditators, to study how neural oscillations are modulated with healthy aging, mental disorders and with meditative practices. In non-human primates, we record using microelectrode chips implanted in the brain and study how vision, cognition and brain stimulation affects brain oscillations, allowing us to understand the mechanisms underlying these processes. This cross-species and cross-modality study of brain signals has applications in Brain-computer Interfacing (BCI) and clinical diagnosis of brain disorders.
