Primary somatosensory cortex located
WebIn the rat whisker system, each whisker is represented by an individual cortical (barrel) column. Here, we quantified in awake, head-fixed rats the impact of natural whisker movements on action potential frequencies of single (identified) neurons located in different layers of somatosensory (barrel) cortex. WebThe highly conserved microRNA-9 (miR-9) is expressed in both neuronal precursors and some post-mitotic neurons, and we detected miR-9 expression in the axons of primary cortical neurons. We found that miR-9 controlled axonal extension and branching by regulating the levels of Map1b, an important protein for microtubule stability.
