WebOct 1, 2024 · Here, we review the genetic and activity-dependent mechanisms of cortical wiring focussing on the importance of their interaction. Cortical circuits emerge from an initial set of neuronal types that engage in sequential forms of embryonic and postnatal activity. ... enabling activity-dependent refinement of retinotopic maps (Fig. 2 D). … WebSep 2, 2009 · One possibility is that sensory-driven activity, which is essential for the proper formation and refinement of neocortical maps (Katz and Shatz, 1996), also drives the desynchronization of cortical network activity. Alternatively, experience-independent (but neuronal activity-dependent factors) could trigger the transition, via mechanisms ...
