Direct Evidence of Plasticity within Human Primary Motor and Somatosensory Cortices of Patients with Glioblastoma

Figure 1

Mechanisms of plasticity. Plasticity occurred in three presumed mechanisms which are illustrated in this figure. Gain of function sites were negative to stimulation at the first surgery and positive to stimulation at the second surgery (Site 1); loss of function sites were the inverse (Site 2). Cross-modal sites were positive to stimulation at both surgeries, but function changed from motor to sensory function or vice versa (Site 3).
