Fig. 5.
Mean normalised rms (root-mean-square) amplitude and SD of the flickering components of responses to a light stimulus (intensity indicated in the abscissa in log quanta μm−2 s−1). Apomorphine, 200 μM, n = 7; SKF, 200 μM, n = 5; Quinpirole, 300 μM, n = 5; grey: control; black: drug. Responses indicated by a star are significant in a MANOVA post hoc—comparison with Bonferoni correction of control and drug-influenced amplitudes.
