Serotonin improves behavioral contrast sensitivity of freely moving rats
Fig 2
Effects of FLX on CS in the 2AFC-VDT combined with the staircase method.
(A)–(B) Typical data from one session of the 2AFC-VDT at two different SFs: 0.1 cpd (A) and 0.5 cpd (B) for one rat (black circles, control; white squares, FLX). Solid and dotted horizontal lines indicate the Cthreshold of the control and FLX conditions, respectively. (C)–(D) Average contrast changes over all sessions for the same rat as (A)–(B). Black circles and white squares indicate the mean contrast value calculated for each trial number. Horizontal lines indicate the geometric mean of Cthreshold (solid line, control; dotted line, FLX). Error bars are SEM.
