We have investigated the properties of neurons in inferior temporal (IT) cortex in monkeys performing a pattern matching task. Simple back(cid:173) propagation networks were trained to discriminate the various stimulus conditions on the basis of the measured neuronal signal. We also trained networks to predict the neuronal response waveforms from the spatial pat(cid:173) terns of the stimuli. The results indicate t.hat IT neurons convey tempo(cid:173) rally encoded information about both current and remembered patterns, as well as about their behavioral context.
