Fig. 2.

Cortical responses to airflow stimulation are diminished after depilation. The averaged poststimulus multiunit responses (time 0, end of air puff) to 10 air puff stimulations are shown for four different wing locations (see color-matched circles in bat schematic; open line, before depilation; filled area, after depilation). During the recording after hair removal, it was first tested whether the center of the tactile receptive field was still in the same location on the dorsal wing surface as before the depilation.
