Thalamocortical convergence in the secondary motor cortex supports adaptive decision-making
Juan Manuel Dafauce Garcia, Angélique Faugere, Mathieu Wolff · FENS Forum 2024
The secondary motor cortex (M2) of rodents appears as a highly integrative brain region, with functions beyond motor processing. It indeed features prefrontal-like thalamocortical connectivity, with prominent innervation from thalamic nuclei involved in adaptive decision-making, namely the mediodorsal thalamic nucleus (MD) and the ventral anterior/ventral lateral thalamic nuclei (VA/VL). To study the functional connectivity between the M2 and the thalamus, we performed tracing experiments and behavioral assays in rats. Through a classic retrograde tracing approach, we identified convergent pro
