Pyramidal Cell Response to Patterns of Synaptic Input Believed to Underlie Gamma Oscillations
The fast oscillations induced in the piriform cortex in response to olfactory stimuli were first recorded some 50 years ago . Since then, 30–80 Hz oscillations (also called gamma) have been found in many other cortical areas as well . The ubiquity of stimulus-induced oscillatory activity in the brain suggests that the neural activity that underlies such oscillations might be critical to neural computation . The question then becomes: How does one elucidate the neural activity that gives rise to these oscillations?
