The implication being that high level areas are involved in inhibition of imitative response tendencies.
And beyond that, even some higher level areas appear to be the same.
These findings extend those from previous studies in several ways: first, they target neurons in higher level areas in the visual hierarchy compared with previous intracranial BR studies in monkeys that did not surpass the inferior temporal cortex44.
Romo says the findings indicate that touch perception arises not in S1 but higher level areas such as MPC, where sensory signals merge with signals related to memory, expectation, and attention.
At this stage, visual areas decompose the visual input into separate feature maps (colour, orientation, motion).. Secondly, all of these signals converge towards higher level areas (e.g. FEF, PEF, PPC).
Oculomotor extrapolations were included to distinguish between potentially distinct extrapolation processes for perception and action, which may involve different higher level areas of the ventral and dorsal streams [22], [47] [49].
David et al. [62] proposed that increases in duration of activation may depend on the increased contribution of top down connections, reflecting re-entry of neural signals to lower-level processing areas, as EPs were found to be more enduring and dispersed in higher level areas [62].
Both kinds of information are integrated in higher level areas such as STS and fusiform areas, resulting in different responses depending on the order of the presented images.
Thus, motion aftereffects likely originate not from adaptation in one area or circuit but from many stages of processing both in early sensory areas and in higher level areas.
This is consistent with a role of top-down signals disambiguating activity in lower areas and enabling a more efficient processing of low-level visual attributes that conform to the processing established by higher level areas.
