The designs of fear conditioning experiments. (A) Schematic drawings of experimental contexts A and B are shown. (B) The schedules of five experiments are listed. White and black rectangles represent the context A and B, respectively. (C) The composition of CS and US presentations is shown. The CS was an 8 kHz continuous tone burst (20 s) and the US (foot shock, 1 s) was delivered immediately after the CS termination. Inter-trial intervals were 60–75 s.
