000155949 520__ $$aTo elucidate the laminar organization of ongoing neural activities and its functional relevance in visual object recognition, we examined spatio-temporal patterns of local field potentials (LFPs) recorded from the inferior temporal cortex of analgesized macaque monkeys using linear electrode arrays (32 probes spanning 1.55 or 3.1 mm). During the recordings the animals were presented with 128 visual objects (shapes, gratings, faces, fruits, etc.) on a gray background. Stimulus duration was 0.5 s with an inter-stimulus interval (ISI) of 1 s. We found that during the ISIs the LFPs showed strong oscillatory fluctuations in the alpha-beta frequency band (10  – 20 Hz). These oscillations had the strongest power at the lowermost probes, supposedly located in the infra-granular layers. These LFP oscillations were considerably suppressed during the stimulus presentation period. In the initial ~0.2 s of the stimulus presentation the LFPs showed a stimulus-evoked excitatory modulation that first occurred in deep layers and then propagated to the superficial layers. The spatio-temporal patterns of the modulation were specific to the presented stimulus. We will discuss the functional implications on the laminar organization of our observations in respect to ongoing and evoked activities and the suppression of ongoing fluctuations by stimulation.
