What is Reentry?
Reentry in nervous systems is the ongoing bidirectional exchange of signals along reciprocal axonal fibers linking two or more brain areas.
.
Reentrant neural processes involve the simultaneous exchange of signals in a coordinated manner among multiple dispersed neuronal populations.

A second definitional point is largely a matter of taste. While from its inception as a cortical process (Edelman, 1978) reentry was used as the descriptor, other authors have since used different words, such as “recurrent” (Lamme and Roelfsema, 2000), “recursive” (Pollen, 2003) or “top-down” and “bottom-up” (Van Essen, 2005) to refer to the same process.
