Fig. 1.

A neuron in the amygdala with a selective excitatory response to an image of one of the researchers running studies with the patient at UCLA. (A) A sampling of 10 pictures eliciting the large responses and their corresponding raster plots and peri-stimulus time histograms (PSTH). Please note that due to copyright issues, the exact images of famous people used in the study were replaced by similar photographs in this figure. Dotted lines mark stimulus onset and offset, 1 sec apart. (B) Median number of spikes (across trials) for each of the pictures presented to the patient. The horizontal line marks the threshold for defining responsiveness (see Methods). Image numbers correspond to the ones shown at the top of each picture in (A).
