Functional and Dysfunctional Sensorimotor Anatomy and Imaging

Publication date: Available online 22 May 2015 Source:Seminars in Ultrasound, CT and MRI Author(s): John L Ulmer , Andrew P Klein , Leighton P Mark , Ibrahim Tuna , Mohit Agarwal The sensorimotor system of the human brain and body is fundamental only in its central role in our daily lives. Upon further examination, it is a system with intricate and complex anatomical, physiological, and functional relationships. Sensorimotor areas including primary sensorimotor, premotor, supplementary motor, and higher order somatosensory cortices are critical for function and can be localized at routine neuroimaging with a familiarity of sulcal and gyral landmarks. Likewise, a thorough understanding of the functions and dysfunctions of these areas can empower the Neuroradiologist and lead to superior imaging search patterns, diagnostic considerations, and patient care recommendations in daily clinical practice. Presurgical functional brain mapping of the sensorimotor system may be necessary in scenarios with distortion of anatomic landmarks, multiplanar localization, homunculus localization, congenital brain anomalies, informing DTI interpretations, and localizing non-visible targets.
