“Study of Gamma oscillations across varying scales of neural integration”
Brain signals often show oscillations at different frequencies, which are tightly coupled to different behavioral states. We are interested in a high-frequency rhythm called “gamma” (30-80 Hz), which is modulated by high-level cognitive processes such as attention, memory, and meditation, and is also highly dependent on the properties of the visual stimulus. In the first part, I will discuss some characteristics of gamma oscillations, in particular how varying the color, size, orientation and contrast of the stimulus can modulate gamma oscillations. In the second part, I will describe our recording setup to simultaneously record spikes, local field potential (LFP), electrocorticogram (ECoG) and electroencephalogram (EEG), which represent neural processing at four different levels, and discuss our efforts to understand the relationship between these brain signals.
