is facilitated. The primary suspect in
suppressing PrV is a neighboring brainstem
nucleus, the nucleus interpolaris (SpVi). A
set of direct inhibitory connections from the
caudal part of SpVi to the PrV have also been
reported recently2. Lee et al.1 tested whether
SpVi indeed mediates PrV suppression by
pharmacologically inactivating it while
stimulating the follicle. Inactivating SpVi
reversed the effects of whisking and facilitated
VPMdm responses. These results suggest that
the motor system suppresses PrV during
whisking via neurons in SpVi.
SpVi receives direct projections from the
somatosensory cortex but is unlikely to receive
