“…The nature of autonomous recovery as a result of pattern completion of lesioned circuits is strikingly demonstrated in the phenomenon known as the serial lesion effect. There are several studies showing that following certain types and location of brain damage, a given lesion created on a single occasion will have more detrimental behavioral effects than exactly the same type and size of lesion created in a stepped fashion over a number of occasions (deCastro & Zrull, 1988;Finger & Stein, 1982;D. R. Meyer, 1988;Nonneman & Kolb, 1979;Travis & Woolsey, 1956).…”

Rehabilitation of the damaged brain can foster reconnection of damaged neural circuits; Hebbian learning mechanisms play an important part in this. The authors propose a triage of post-lesion states, depending on the loss of connectivity in particular circuits. A small loss of connectivity will tend to lead to autonomous recovery, whereas a major loss of connectivity will lead to permanent loss of function; for such individuals, a compensatory approach to recovery is required. The third group have potentially rescuable lesioned circuits, but guided recovery depends on providing precisely targeted bottom-up and top-down inputs, maintaining adequate levels of arousal, and avoiding activation of competitor circuits that may suppress activity in target circuits. Empirical data are implemented in a neural network model, and clinical recommendations for the practice of rehabilitation following brain damage are made.
