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

Table 3

Mechanisms and sensorimotor representation of plasticity. We categorized the stimulation sites into plastic or nonplastic. Overall, 63% of sites were plastic, with motor and sensory plasticity distributed as shown. The cross-modal plasticity seen was a motor-to-sensory change. Based on the observed mechanism of plasticity, either distant or near recruitment was assigned.

Patient #	Plasticity % (of total sites)	Motor sites (of plastic)	Sensory sites (of plastic)	Cross-modal sites (of plastic)	Recruitment
1	50%	50%	50%	0%	Distant
2	36%	25%	75%	0%	Distant
3	74%	22%	64%	14%	Near
4	60%	67%	33%	0%	Distant
5	0%	0%	0%	0%	None
6	90%	67%	33%	0%	Distant
