Overview of the ECoG film-watching experiment. (a) Experimental setup. The audiovisual film was presented to each participant while their neural responses were collected with ECoG electrodes. (b) Total electrode coverage over 37 participants. The panel shows a clear bias toward covering the left hemisphere. Each single subject electrode location is projected onto the MNI common brain. (c) The surface representation of the coverage density. Each single subject electrode location was assigned a value of one and projected to a regular grid in the average Freesurfer space. The resulting overlay shows the density of coverage over all individual participants. The panel shows the same bias for the left hemisphere as well as better overall coverage of inferior frontal and temporal cortices. Considerable coverage of inferior temporal and fusiform regions can be seen, whereas calcarine sulcus and lingual gyrus are covered quite scarcely. See “Methods” for more details about the projection to a uniform regular grid on the average surface.
