Neural binding

From Wikipedia, the free encyclopedia

According to the neural binding hypothesis, neurons within neuronal assemblies fire in synchrony to link different features of neuronal representations together.[1] These features can include, shape, motion, color, depth, and other aspects of perception. Neural oscillations have been suggested as the mechanism of binding.

Concerning sensory awareness, neural binding accomplishes synchronization in the order of milliseconds via a process described as “dynamic binding by transient and precise synchronization of neuronal discharges”.[2] Individual neurons bound to one neural net can transition, joining another neural net, contingent upon the “coincidence-sensitive neurons” which recruit them.[2][3] Experimental confirmation for the existence of coincidence-sensitive neurons, has been offered by in vivo recordings of cortical auditory regions.[1][4] The experiment employed excitatory and inhibitory potentials to induce binding within a relatively small population of the primary auditory neurons. This produced a magnification of neuronal activity within their associated networks.[5] The outcome was measured by global output of neural oscillations.[1][4]
