These parts are responsible for integrating touch and vision into a coherent perception.
86, 87 Taken together, it is interesting to speculate whether there is a commonality in the way that the brain deals with temporal and spatial information to create a meaningful and coherent perception of the world around us.
It assembles simple linear segments, each aligned in a specific direction, obtaining outlines that define the borders of an image, and builds up coherent perception of the shape of an object.
How these widely spaced neuronal responses are "bound" together into the coherent perception of a rolling apple is, as yet, unknown.Some neuroscientists, notably Wolf Singer, at the Max Planck Institute in Frankfurt, think the brain achieves perceptual binding by combining the activities of disparate groups of nerve cells into one synchronised, wavelike processing unit.
This supports the hypothesis that theta-modulated gamma-band synchronizations are essentially related to perceptual experience and define discrete 'frames' of consciousness, consistent with results from attentional blink experiments and those investigating coherent perception of visual images [19], [24].
The brain's amazing capacity to filter sensory information is critical to forming coherent perceptions of the world.
The road from multineuronal activity patterns to coherent perceptions of dynamic visual scenes probably involves also processes related to visual memory such that timescales operant for stimulus representation (<100 ms) could be bridged with behaviorally relevant timescales (>500 ms).
As these conditions also increase the perception of sense of ownership, it makes sense to assume that bottom-up information (provided through synchrony) and top-down information (provided by modality) are integrated into a coherent percept (Zhang & Hommel, 2016).
Uhlhaas and colleagues [ 12] investigated schizophrenic patients during a Gestalt perception task and discovered a reduction of beta-band phase synchrony that might be related to their impairment in grouping stimulus elements together to form a coherent percept.
