Presentation on theme: "Plate 1. A topographical mapping of the Nc component that occurs during sustained attention and inattention for the frequent familiar, infrequent familiar,"— Presentation transcript:

1 Plate 1. A topographical mapping of the Nc component that occurs during sustained attention and inattention for the frequent familiar, infrequent familiar, and infrequent novel stimuli. The data in each figure represent an 80ms average of the ERP for the Nc component at the maximum point of the ERP response. The data are plotted with a cubic spline interpolation algorithm, with an averaged electrode reference, and represent absolute amplitude of the ERP (from Richards, 2000c).

2 Plate 3. Equivalent current dipole analysis of the presaccadic ERP potential occurring at 50ms before a target in an expected location. The equivalent current dipole (bottom) generated a scalp topographical potential map (top right) that matched the recorded ERP (top left).

6 Plate 8. Left: Visual cortex is composed of columns of cells responsive to lines of different orientation (see colour code at right). In normal developing cats, a dramatic sharpening of the borders occurs between postnatal (P) days 21 and 33. In cats whose eyes have been sutured shut, the orientation columns develop normally until P26 and then their responses deteriorate rapidly. Patterned stimulation is only necessary for maintenance, not for formation, of the orientation columns (reprinted with permission from Crair et al. (1998).
