Example of a layer II/III cell showing non-direction-selective facilitation. A, The cell was located at the septal region near E2 barrel column. B,Left and right columns, Whiskers were deflected in the rostral (left) and caudal (right) directions. Top andmiddle, Responses to single whisker stimulation of E1 and E2, respectively. Bottom, Response to simultaneous stimulation of E1 and E2. Similar magnitudes of responses were observed for both directions of deflections. C, ISI tuning curve. Other notations are as in Figure 2.
