Overview
This is ECoG data from Matsuo T, Kawasaki K, Osada T, Sawahata H, Suzuki T, Shibata M, Miyakawa N, Nakahara K, Iijima A, Sato N, Kawai K, Saito N, Hasegawa I (2011): "Intrasulcal electrocorticography in macaque monkeys with minimally invasive neurosurgical protocols" Front. Syst. Neurosci., 5, p. 34. In this study, a newly-designed ultra-thin ECoG probe was introduced. The feasibility of the new ECoG protocol was demonstrated by the high signal-to-noise ratio of the signals and low (almost no) physical damage in the implanted areas.
Task
A macaque monkey was trained in a visual fixation task to keep the gaze within !^1!k from the fixation target. 24 photographs of objects from a wide variety of categories, including faces, foods, houses, cars, etc. were presented as stimuli. Each stimulus was presented for 300 ms followed by a 600-ms blank interval.
Data
128-channel ECoG data from the temporal lobe, recorded at 1000 Hz are included.
