Recently, we have been able to read out a human/monkey face category-boundary from singleunit- activity (SUA) recorded from the inferior-temporal (IT) cortex of a macaque monkey brain. This data was collected in an experiment where monkeys have to fixate at pictures of human/monkey morphed faces at different levels of this ‘species-continuum’. Consistent with our previous psychophysical experiments in which human subjects have to categorize morphed faces as humans or monkeys, the perceptual boundary seems to be shifted towards the ‘own-species’ category (approximately 60% human/40% monkey in humans and the other way around in the monkey data). Similar to the ‘other-race’ effect, this effect suggests a perceptual bias that could be due to long-term learning. The local field potential (LFP) refers to the low-frequency (< 300Hz) component of signals recorded from the brain, and it has been associated with dendritic activity within a particular recording area. In this work we investigate to what extent these LFP signals are stimulus selective and weather they correlate with our previous results obtained from the simultaneously recorded spiking activity (SUA).To achieve that, we first extract different features from the LFP signals such peak amplitude,
