“…In these electrophysiological studies, using an experimental approach very similar to the one described here, electric and magnetic responses evoked by pursuit-induced retinal image motion attributed to MT+ did not show a dependency on the reference signal. A noteworthy point of difference between our results and previous work relates to the already mentioned study of Tikhonov et al (2004). In that study, reference-signal-related evoked magnetic fields were attributed to a single equivalent current dipole located on the medial aspect of the parietooccipital cortex (PO), absent in the present investigation.…”

“…This is in line with previous electroencephalogram (Haarmeier & Thier, 1998) and magnetoelectroencephalogram (Tikhonov, Haarmeier, Thier, Braun, & Lutzenberger, 2004) studies. In these electrophysiological studies, using an experimental approach very similar to the one described here, electric and magnetic responses evoked by pursuit-induced retinal image motion attributed to MT+ did not show a dependency on the reference signal.…”

“…Moreover, this latter study demonstrated an inverse interaction between PO and the PIVC during the perception of self-rotation. The lack of activation of PO in our study could be due to differences in stimulus size (Previc, Liotti, Blakemore, Beer, & Fox, 2000): Both Tikhonov et al (2004) and Brandt et al (1988) used visual stimuli considerably larger ($900% and $1700%, respectively) than the visual background employed here.…”

Despite smooth pursuit eye movements, we are unaware of resultant retinal image motion. This example of perceptual invariance is achieved by comparing retinal image slip with an internal reference signal predicting the sensory consequences of the eye movement. This prediction can be manipulated experimentally, allowing one to vary the amount of self-induced image motion for which the reference signal compensates and, accordingly, the resulting percept of motion. Here we were able to map regions in CRUS I within the lateral cerebellar hemispheres that exhibited a significant correlation between functional magnetic resonance imaging signal amplitudes and the amount of motion predicted by the reference signal. The fact that these cerebellar regions were found to be functionally coupled with the left parieto-insular cortex and the supplementary eye fields points to these cortical areas as the sites of interaction between predicted and experienced sensory events, ultimately giving rise to the perception of a stable world despite self-induced retinal motion.

“…Second, the parieto-occipital cortex contains functional areas associated with the visual control of body effectors [72]. Regions of the superior and medial portions play a critical role in proximal and distal aspects of reaching/grasping movements, pointing gestures, head movements and eye-gaze shifts [73]–[75]. Motion selectivity has also been observed within this region [76], indicating dorsal visual stream involvement [77].…”

Event-Related Alpha Suppression in Response to Facial Motion

et al. 2014

While biological motion refers to both face and body movements, little is known about the visual perception of facial motion. We therefore examined alpha wave suppression as a reduction in power is thought to reflect visual activity, in addition to attentional reorienting and memory processes. Nineteen neurologically healthy adults were tested on their ability to discriminate between successive facial motion captures. These animations exhibited both rigid and non-rigid facial motion, as well as speech expressions. The structural and surface appearance of these facial animations did not differ, thus participants decisions were based solely on differences in facial movements. Upright, orientation-inverted and luminance-inverted facial stimuli were compared. At occipital and parieto-occipital regions, upright facial motion evoked a transient increase in alpha which was then followed by a significant reduction. This finding is discussed in terms of neural efficiency, gating mechanisms and neural synchronization. Moreover, there was no difference in the amount of alpha suppression evoked by each facial stimulus at occipital regions, suggesting early visual processing remains unaffected by manipulation paradigms. However, upright facial motion evoked greater suppression at parieto-occipital sites, and did so in the shortest latency. Increased activity within this region may reflect higher attentional reorienting to natural facial motion but also involvement of areas associated with the visual control of body effectors.

“…A second component occurred around 300 ms occipitotemporally. Tikhonov et al [148] compared two conditions where the same stimuli and eye movements yielded different percepts due to changes of a reference stimulus and obtained an effect with the same latency as the N2 in Hoffmann and Bach's study, but with a different scalp distribution and a likely origin in the medial parietooccipital sulcus.…”

Motion visual evoked potentials (motion VEPs) have been used since the late 1960s to investigate the properties of human visual motion processing, and continue to be a popular tool with a possible future in clinical diagnosis. This review first provides a synopsis of the characteristics of motion VEPs and then summarizes important methodological aspects. A subsequent overview illustrates how motion VEPs have been applied to study basic functions of human motion processing and shows perspectives for their use as a diagnostic tool.
