    Notes: [Auszug] Sleep has been shown to favour retention6 but it is not known how. If REM sleep is a positive process of consolidation and does not merely protect the trace from new input (as the "interference theory" of forgetting would predict) it might provide either a simple "setting" of the trace or an active ...

    Notes: Summary Human averaged visual evoked potentials (VEPs) have been recorded to the onset, reversal and offset of the motion of a visual noise pattern. The VEPs have been analysed into components, distinguishable by their different scalp distributions, and by their distinct dependences on the retinal area stimulated and the pattern velocity. The effects of varying the form and the scale of the pattern have been investigated. The VEPs were almost invariant with respect to changes in the brightness, the direction of motion, and the sharpness of the boundary of the visual field. Under some circumstances the motion-reversal VEP was very similar to the sum of the motion-onset and the motion-offset VEPs. These VEPs will qualify as a useful tool for investigating the processing of movement information only if they can be shown to be genuine responses to changes in the motion as such. Discussion of this question has been deferred to the following paper.

    Notes: Summary Human averaged visual evoked potentials (VEPs) have been recorded to the onset, reversal and offset of motion of a visual noise pattern as in the previous paper; and to the appearance and disappearance of stationary and of moving noise patterns. These VEPs have been compared. The VEPs to motion-reversal and -offset and pattern-appearance were very similar in waveform and scalp-distribution, and in inter-subject variation; and all three components of each of these VEPs reversed polarity between upper and lower half-field stimulation. Motion-onset and pattern-disappearance VEPs were similar to each other but very different from the former group of VEPs; and they did not clearly exhibit polarity reversal between the upper and lower half-fields. The pattern-appearance and -disappearance VEPs were largest for stationary patterns, and all components were steadily reduced as the stimulus velocity was increased. Previous research implies that the motion-reversal VEPs are genuine responses to changes in the motion as such. From the data presented in this and the previous paper it is concluded that the motion-offset and -onset VEPs likewise may be largely the product of motion-sensitive mechanisms when the stimulus velocity is less than about 10dg/sec.
