WebStudies have shown that gamma oscillations (30-100 Hz) are relevant for neurocircuit function, behavior, and memory. To examine a possible causal contribution of gamma oscillations to cognitive function, recent studies have employed various types of brain stimulation to induce gamma oscillations. Te … WebApr 23, 2024 · Gamma oscillations appear to emerge when visual inputs contain features that match the tuning of local cortical neurons, and when these features are presented in a spatially coherent manner across the receptive field and its surround . The presence of these highly represented visual features in the stimulus creates a strong excitatory drive ...
WebNov 18, 2024 · Gamma oscillations are a prominent activity pattern in the cerebral cortex. While gamma rhythms have been extensively studied in the adult prefrontal cortex in the context of cognitive (dys)functions, little is known about their development.
