Description |
Achieving behavioral goals requires integration of sensory and cognitive
information, across cortical laminae and cortical regions. How this
computation is performed remains unknown. Using local field potential
recordings and spectrally resolved conditional Granger causality (cGC)
analysis, we mapped visual information flow, and its attentional
modulation, between cortical layers within and between macaque areas V1
and V4. Stimulus induced inter-laminar information flow within V1
dominated upwardly, channeling information towards supragranular
cortico-cortical output layers. Within V4, information flow dominated
from granular to supragranular layers, but interactions between
supragranular and infragranular layers dominated downwardly.
Low-frequency across-area communication was stronger from V4 to V1, with
little layer specificity. Gamma-band communication was stronger in the
feedforward V1 to V4 direction. Attention to the receptive field of V1
decreased communication between all V1 layers, except for granular to
supragranular layers interactions. Communication within V4, and from V1
to V4, increased with attention across all frequencies. While
communication from V4 to V1 was stronger in lower frequency bands (4-25
Hz), attention modulated cGCs from V4 to V1 across all investigated
frequencies. Our data show that top down cognitive processes result in
reduced communication within cortical areas, increased feedforward
communication across all frequency bands and increased gamma band
feedback communication.
