Analysis on Bilateral Hindlimb Mapping in Motor Cortex of the Rat by an Intracortical Microstimulation Method
Intracortical microstimulation (ICMS) is a technique that was developed to derive movement representation of the motor cortex. Although rats are now commonly used in motor mapping studies, the precise characteristics of rat motor map, including symmetry and consistency across animals, and the possibility of repeated stimulation have not yet been established. We performed bilateral hindlimb mapp...
متن کاملThe somatotopic organization of the supplementary motor area: intracortical microstimulation mapping.
The somatotopic organization of the supplementary motor area (SMA) is commonly held to consist of a rostrocaudal sequence of orofacial, forelimb, and hindlimb representations. Recently, however, this somatotopy has been questioned. Studies of regional cerebral blood flow in humans and the movements evoked by intracortical electrical stimulation in cynomolgus monkeys have been unable to reveal e...
متن کاملDiscriminability of Single and Multichannel Intracortical Microstimulation within Somatosensory Cortex
The addition of tactile and proprioceptive feedback to neuroprosthetic limbs is expected to significantly improve the control of these devices. Intracortical microstimulation (ICMS) of somatosensory cortex is a promising method of delivering this sensory feedback. To date, the main focus of somatosensory ICMS studies has been to deliver discriminable signals, corresponding to varying intensity,...
متن کاملTypes of monocular eye movements studied by intracortical microstimulation in the cat's coronal sulcus.
To study the types of the monocular eye movements, intracortical microstimulations were applied to the fundus of the cat's coronal sulcus where the monocular movements of the contralateral eye were evoked. The monocular eye movements were saccadic and directed toward the nasal side converging on a horizontal line from various eye positions. The average threshold and latency were 18.0 microA (ra...
متن کاملComplex movement topography and extrinsic space representation in the rat forelimb motor cortex as defined by long-duration intracortical microstimulation.
Electrical stimulation of the motor cortex in the rat can evoke complex forelimb multi-joint movements, including movement of limb and paw. In this study, these movements have been quantified in terms of 3D displacement and kinematic variables of two markers positioned on the wrist and middle digits (limb and paw movement, respectively). Electrical microstimulation was applied to the motor cort...
