Recovery time and sensorimotor cortex lesion effects
Physiology & Behavior, 1982Rats received one-stage, bilateral lesions of the individual sensorimotor cortex areas (Sm-1, Sm-2) and were compared to sham operated rats or rats with lesions of Sm1 + 2 in learning a series of 5 ridge-smooth tactile discriminations. Some rats began testing 1 or 2 weeks after surgery, while others remained in their home cages for 1 month, 6 months, 1

Functional somatotopy in sensorimotor cortex
NeuroReport, 2005In an effort to understand the highly distributed somatotopy of primary motor cortex, this review draws on principles derived from studies of auditory, visual and somatosensory cortical areas. In each case, a behaviorally important feature or function is overlaid in multiple locations on an underlying topographic map of the peripheral sensory surface ...

The Concept Of A Sensorimotor Cortex
Brain, 1978A brief account has been given of the events during the last quarter of the nineteenth century which led to the concept of the sensorimotor cortex. An early review by Frederick Mott has served as a useful guide. Particular attention has been paid to two early startlingly prescient papers by W. Bechterew.

The premotor corte× and nonstandard sensorimotor mapping
Canadian Journal of Physiology and Pharmacology, 1996We often gaze at and attend to an object while preparing to reach toward and grasp it, and continue doing so when the plan is executed. Elaborate machinery, much of it in the brainstem and spinal cord, provides control systems for the spatially congruent guidance of the eyes, limbs, and body toward targets in visual space. We will use the term standard

Primary Afferent Depolarization Evoked from the Sensorimotor Cortex
Acta Physiologica Scandinavica, 1963AbstractStimulation of the sensorimotor cortex evokes dorsal root potentials (DRP) in the lumbo‐sacral cord. Primary afferent depolarization is evoked in group Ib and group II muscle af‐ferents and cutaneous afferents but not in Ia afferents. The effects are mediated by the pyramidal tract.

Functional subdivisions of the rat somatic sensorimotor cortex
Behavioural Brain Research, 1990The behavioural impairments and subsequent recovery were studied in rats with circumscribed unilateral lesions in the somatic sensorimotor cortex (SMC). Lesions were made in the caudal forelimb region (CFL), the rostral forelimb region (RFL), the anteromedial cortex (AMC) or the hindlimb area.

Focal brain hyperthermia: Evoked responses in sensorimotor cortex
Experimental Neurology, 1978Abstract Focal cerebral hyperthermic methods were used for the study of induced changes in evoked responses of the sensorimotor cortex. (i) Responses induced by electrical stimulation of the dentate nucleus were enhanced by focal cerebral hyperthermia of the responding region.

Invasive Studies of Sensorimotor Cortex Epilepsy
2018Intracranial exploration of the sensorimotor cortex exemplifies the balance of preserving function while optimizing the surgical quest for seizure freedom. While surgical intervention in the sensorimotor region is certainly a ‘high-stakes’ undertaking, positive results can be obtained for carefully selected patients.

Depth EEG in Sensorimotor Cortex Epilepsy
2018Surgery for intractable seizures originating from the sensorimotor cortex is associated with a risk of permanent deficit and a risk of incomplete epileptogenic tissue removal. Depth electrode implantation in the sensorimotor region has been performed over several decades with acceptable morbidity. Motor, sensory, premotor, supplementary motor area, and

Decoding bipedal locomotion from the rat sensorimotor cortex
Journal of Neural Engineering, 2015Decoding forelimb movements from the firing activity of cortical neurons has been interfaced with robotic and prosthetic systems to replace lost upper limb functions in humans. Despite the potential of this approach to improve locomotion and facilitate gait rehabilitation, decoding lower limb movement from the motor cortex has received comparatively ...
