Figure 4

Frequency indexes of anxiety-like behavior testing following foot shock stress. (a) The time spent in the open arms (Time in OA %) in the EPM test. (b) The number of open arm entries (OA Entries %) in the EPM test. (c) The time spent in the inner area (Time in IA %) in the OFT. (OA= open arms, IA = inner area; values expressed in (means ± SEM)%; for each group, = 9, = 6; < 0.05, < 0.01 versus corresponding group of without shock; #< 0.05, ##< 0.01 music groups versus corresponding control groups after shock).
