Event Abstract Back to Event Adaptation: A functionalist perspective Karl J. Friston1* 1 Wellcome Trust Centre for Neuroimaging, University College London, United Kingdom We will ague that adaption (as a neurophysiological phenomenon) has an essential role from a functionalist perspective and try to understand it as part of perceptual inference in the brain. In brief, purely theoretical considerations suggest that perception has to optimize two things; the cause of a sensory inputs and the precision of that input. This is a bit like computing a t-test; using the difference in group means and standard error (inverse precision). We will suggest that adaption reflects the optimization of post-synaptic sensitivity to encode the precision of sensory information, while plastic changes in synaptic connections represent an optimization of the internal model of what caused that input.
