Figure 2

Typical examples of shifts of orientation tuning curve peaks.

Tuning shifts are underlined by horizontal colored arrows. The downward red arrow heads indicate the adapting orientation in this and all figures. Upper left insert shows the respective positions of three receptive fields. Only receptive field A was adapted. Waveforms of respective sorted out action potentials are shown below the insert. Tuning curves pre- and post-adaptation are illustrated for each stimulated site (Upper right row: site A, lower left row: site B, lower right row: site C). The curves represent raw data and Gaussian fits. Light colors indicate error bars. Orientations of gratings are depicted on X-axis. OSI's and R-squared are indicated for each tuning curve.
