Areas of Research: Understanding how embryonic neural precursors generate the neocortex, the seat of our highest cognitive functions, and devising methods of regenerating the principle neurons of the adult neocortex when they are lost.

Professional Interests

Generating and regenerating the neocortex

 

The Hébert lab has traditionally studied how the forebrain develops using conditional genetic methods in mice. Recently, the focus of the lab has transitioned to two new areas of interest. First, we are studying how homeostasis is maintained in the adult forebrain using primarily molecular genetic techniques to manipulate the expression of regulatory genes in neural stem and progenitor cells. Specifically, we are examining how neurogenesis is maintained in the hippocampus, how the myelination of axons is maintained through continuous oligodendrogenesis, and how cells become reactive to brain damage.

Second, we are devising novel methods to regenerate the damaged neocortex, the part of our brains that we use for our highest cognitive and perceptual functions. Neocortical damage can be local, due for example to stroke or trauma, or widespread, due for example to neurodegeneration or aging. Among the approaches we are taking, we are developing ways of replacing the principle neurons of the adult neocortex without significantly disrupting the function of existing neural circuits. These approches involve the use of mixed cell populations for transplantation and for widespread damage the use of cells that can disperse throughout the neocortex to repopulate and bolster existing neural circuits with new cells.
