Topic: Bilateral sensory information

Bilateral sensory information is indispensable for navigating the world. In most mammals, signals sensed by either side of the midline will ultimately reach the cortex where they will be integrated for perception and appropriate action selection. Even though information transferred across the hemispheres is routed through the corpus callosum, how and which microcircuits are key in integrating it across development is not well understood. Here we identify an essential role for layer 1 NDNF+ inhibitory cells of mice in controlling the bilaterally evoked whisker stimulation in layer (L)4 before,
