Research

Changes to our bodies have a dramatic impact on our everyday life. Slow changes include development and aging, whereas fast changes often stem from the environment. We are interested in the internal representation of the body as we suspect it to be critical for coping with such changes.

In my first project we investigated whisker regrowth in rats as a model system for slow changes of the body. We found that follicle anatomy, peripheral innervation and cortical responses to whisker deflection are similar for regrowing and existing whiskers. We suggest that this congruence contributes to perceptual stability over whisker regrowth.

Furthermore, I would like to focus on internal responses to fast changes to the body. Ticklish behavior is such a response and neural correlates of ticklishness have already been studied in our laboratory. I would like to extent this knowledge using various experimental strategies.

Techniques:

-Extracellular and juxtacellular recordings in anesthetized, awake head-fixed and freely-moving rats

-Nano- and micro-stimulation

-Anatomical techniques: Tracing, identification of recorded cells, whisker follicle anatomy
