a) the percentage of rats in control (top row) and ACRS (bottom row)
that interacted with the lever cue only (white), cup only (black), both lever
and cup (light grey), or neither stimulus (dark grey) on the first ever lever
extension on sign/goal tracking training day 1 (left column), or the first cue
presentation on the 8th training day (right column). b)
In each panel, m+SEM hand-scored interactions with the food cup (top
left), cue lever (top right), or inactive lever (bottom right), or rears (bottom
left) are shown during the first 5, or last 5 cue presentations on sign/goal
tracking training days 1, 2, and 3. *p<0.05, interaction of ACRS
× cue block. c) m+SEM rate of CS+ lever
depressions (depressions/sec) on each training day in control (black line) and
ACRS rats (grey line). d) m+SEM rate of food cup entries
during cues (solid black, grey lines) or in non-cue periods (dashed black, grey
lines). *p<0.05, ACRS group × day interaction.
