TL;DR: Investigating the mouse whisker system, this work found an additional and equally direct pathway for cortical motor control driven by the primary somatosensory cortex, providing a rapid negative feedback signal for sensorimotor integration.

TL;DR: These long‐range connections of the barrel cortex with other specific cortical and subcortical brain regions are likely to play a crucial role in sensorimotor integration, sensory perception and associative learning.

TL;DR: Evidence is presented from studies on mouse cortex that modulation of vasomotion, i.e., intrinsic ultra-slow (0.1 Hz) fluctuations in arteriole diameter, provides this link between fluctuations in blood oxygenation and neuronal signaling pathways, which links neuronal pathways to functional connections.

TL;DR: It is concluded that FS GABAergic neurons play an important role in neocortical microcircuit function through their strong local synaptic connectivity, which might contribute to driving sparse coding in excitatory layer 2/3 neurons of mouse barrel cortex in vivo.

TL;DR: It is demonstrated that selective activation of cortical excitation and inhibition elicits distinct vascular responses and the vasoconstrictive mechanism is identified as Neuropeptide Y (NPY) acting on Y1 receptors, implying that task-related negative Blood Oxygenation Level Dependent fMRI signals in the cerebral cortex under normal physiological conditions may be mainly driven by the NPY-positive inhibitory neurons.
