Table 1. Summary experimental results for VPM, L4 excitatory and L4 FS neurons.

Data are taken from [37]. The increase of the average spike rate of L4 excitatory neurons from non-whisking to whisking conditions was found to be insignificant. Values are reported as mean ± standard deviation. In comparison to VPM neurons, the average response of L4 excitatory neurons is reduced by a factor of 2 in response to touch and by a factor of 20–30 in response to whisking onset.
