Fig. 7. The depth profile of the response to afferent nerve (Aff) and parallel
fibers (PF) stimulation. (A,B) The responses to Aff nerve stimulation (A) and
PF stimulation (B) at different locations along a single path of the
microelectrode through the dorsal ventral axis of the DON. Each record is an
average response to eight consecutive stimuli delivered at a rate of 0.1 Hz.
The depth from the DON surface is indicated. (C,D) The changes in the
responses to Aff (C) and PF (D) stimulation, as a function of the depth of
recording. The relative voltage was measured at three times along the response
as indicated on the corresponding insets. In C, the voltage was measured at 3,
6 and 8 ms from the time of stimulation and it is represented as diamonds,
squares and triangles, respectively. In D, the voltage was measured at 8, 12
and 16 ms from the time of stimulation and it is represented as diamonds,
squares and triangles, respectively. These specific times were selected to
denote the three phases of the triphasic response.
