Abstract

Macaque monkeys were presented with continuous rapid serial visual presentation (RSVP) sequences of unrelated naturalistic images at rates of 14-222 msec/image, while neurons that responded selectively to complex patterns (e.g., faces) were recorded in temporal cortex. Stimulus selectivity was preserved for 65% of these neurons even at surprisingly fast presentation rates(14 msec/image or 72 images/sec). Five human subjects were asked to detector remember images under equivalent conditions, Their performance in both tasks was above chance at all rates (14-111 msec/image). The performance ofsingle neurons was comparable to that of humans anti responded in a similar way to changes in presentation rate, The implications for the role of temporal cortex cells in perception are discussed.
