We used functional magnetic resonance imaging to examine the representation pattern for repetitive voluntary finger movements in the primary motor cortex (M1) and the supplementary motor area (SMA) of humans	I. Indovina; J. N. Sanes. On somatotopic representation centers for finger movements in human primary motor cortex and supplementary motor area. NeuroImage 13(6 Pt 1):1027-34, 2001. PMID: 11352608. DOI: 10.1006/nimg.2001.0776. WOBIB: 11.
Within the primary motor cortex, a hand region was preferentially active in the task in which the stimulus was painful heat	P. A. Gelnar; B. R. Krauss; P. R. Sheehe; N. M. Szeverenyi; A. V. Apkarian.

WOBIB: 75.
Electrodermal activity was positively related to rCBF in the left primary motor cortex (MI, Brodmann's Area 4) and bilaterally in the anterior (Areas 24 and 32) and posterior cingulate cortex (Area 23)	M.

Cerebral blood flow (CBF) increases just below the threshold for statistical significance were seen in the contralateral sensorimotor cortex [primary motor cortex (M1)/primary somatosensory cortex (S1)]	K.

RESULTS: Brain regions in which activity was significantly correlated with tic occurrence in the group included medial and lateral premotor cortices, anterior cingulate cortex, dorsolateral-rostral prefrontal cortex, inferior parietal cortex, putamen, and caudate, as well as primary motor cortex, the Broca's area, superior temporal gyrus, insula, and claustrum	E.
