Abstract

Introduction and development. Alterations of sensory experience cause large-scale re-arrangements of cortical connectivity only early in life. After a critical period that roughly ends by puberty, comparable modifications requires more invasive manipulations, including deafferentation and cortical lesions. At a cellular level, the elementary mechanisms responsible for synaptic modification appear to be available throughout life. Thus, in adults, experience dependent plasticity might be constrained additional factors, like the maturation of inhibition or changes in the extra cellular matrix. Such view is consistent with a limited, but not absent, modifiability of adult cortical circuits. This view also has interesting therapeutical implications. Conclusion. In this scenario, manipulation of these limiting factors, for example reducing synaptic inhibition, might be a useful strategy to enhance plasticity and to restore function in the adult cortex.
