Effects of the pre- and post-needle insertions on spatiotemporal fluorescence activities. a The peak activated fluorescence signals were not changed between pre- and post-needle insertions. b The maximal activated areas in S1 cortex were compared. Maximal activated areas between pre- and post-needle insertions were not significantly different (n = 4)
