Such kinaesthetic activation during perception produces an implicit and pervasive reference to one's own body.
But the researchers found that each participant's recall brain activity closely matched the group average during perception.
These measures represent worst-case conditions for simple perceptual behaviors, but fail to account for the kind of challenges faced during perception under real world complexity and variability.
Further, there was enough correspondence between imagery and perception to allow discrimination of individual imagined objects based on the response during perception.
While much is known about the functional architecture of the visual system, little is known about its large-scale dynamics during perception.
A framework introduced in the late 1980s proposed that mental images arise from neural activity in early sensory cortices both during perception and recall.
Also, leaf rolling occurs typically in most grasses including rice, maize, and sorghum during perception of drought induced by increased production of salicylic acid signal (Kadioglu and Terzi 2007).
This thread of research revealed that humans reuse those brain structures that are active during perception when mentally imagining an object or action (Barsalou, 1999, 2003, 2008; for an overview on this aspect, see Anderson, 2010).
Probabilistic learning is a fundamental mechanism of the brain, which extracts and represents regularities of our environment enabling predictive processing during perception and acquisition of perceptual, motor, cognitive, and social skills.
Talking or thinking about objects have been suggested to imply the reactivation of previous experiences, and the recruitment of the same neural circuits involved during perception and action towards those objects would allow the re-enactment of multimodal information (color, size, width, etc).
These patches get integrated during perception in a process called "optical mixing" where your brain combines them.
