Optimizing parameters for terminating cortical afterdischarges with pulse stimulation
GK Motamedi, RP Lesser, DL Miglioretti… - …, 2002 - Wiley Online Library
Purpose: We previously reported that brief pulses of electrical stimulation (BPSs) can terminate

Functional mapping of human sensorimotor cortex with electrocorticographic spectral analysis. II. Event-related synchronization in the gamma band.
…, DL Miglioretti, B Gordon, RP Lesser - Brain: a journal of …, 1998 - academic.oup.com
It has been shown in animals that neuronal activity in the 'gamma band' (>30 Hz) is associated
with cortical activation and may play a role in multi-regional and multi-modal integration of …
