We utilize optogenetic tools for a temporally and
spatially defined modulation of components of the
cortico-thalamic and the thalamo-cortical neuronal
network in nave rats and use BOLD fMRI as a global,
noninvasive readout. Our results show positive BOLD
activation of S1 sensory cortex upon optogenetic
stimulation of S1 or the posterior thalamic nuclei
group, and negative BOLD response upon inhibitory
stimulation.
