Figure 10.
Signal Strength as a function of depth and time. a) Mean SU voltage amplitude. b) Mean voltage amplitude + 2*STD of activity dependent unsorted units. Note: greater amplitude is detected around layer IV and in CA1. c) LFP Peak Power of the ON response. Note increase in peak power occurs at same depth and days as SNLPR increase is seen in Figure 8c. Zeroes were separated in the heat maps to better illustrate the signal quality across layers. Probability of recording a significant signal can be examined via the yield plots.
