Virtual movement

From A conversation about the brain

The ideas described in these pages are primarily focussed on the sensory consequences of real movements in the world and what type of representation is useful for (i) guiding these movements and (ii) storing sensory information as the observer moves. Nevertheless, there are several points at which ‘virtual movement’ has been mentioned, e.g when imagining making a cup of tea rather than actually doing it. The assumption here has been that the paths through sensory+motivational space in imagining a sequence of movements (e.g. planning a chess move) are very similar to those involved in carrying out those movements, but this assumption needs to be examined carefully.
