The study of inter-laminar functional connectivity
within the primary somatosensory (S1) cortex provides
great depth of knowledge about input and output
information process in S1 cortex for somatic sensation,
but few studies have resolved the contributions of
different cortical layers to measured BOLD signals. In
this work, we performed sub-millimeter resolution
resting-state functional MRI in the S1 cortex in
anesthetized squirrel monkeys and examined the laminar
specific functional connectivity between sub-regions
(area 3a, area 3b and area 1) of the S1 cortex.
