In Vivo Voltage-Sensitive Dye Study of Lateral Spreading of Cortical Activity in Mouse Primary Visual Cortex Induced by a Current Impulse. [PDF]

PLoS ONE, 2015
In the mammalian primary visual cortex (V1), lateral spreading of excitatory potentials is believed to be involved in spatial integrative functions, but the underlying cortical mechanism is not well understood.

Corticospinal Tract Development, Evolution, and Skilled Movements

Movement Disorders, Volume 40, Issue 7, Page 1221-1232, July 2025.
Abstract The evolution of the corticospinal tract (CST) is closely linked to the development of skilled voluntary movements in mammals. The main evolutionary divergence concerns the position of the CST within the spinal cord white matter and its postsynaptic targets in the grey matter.

Targeted Sensory System Neuromodulation Improves Sensorimotor and Cognitive Deficits After Brain Injury: Bridging Mechanisms to Practice

Neural Plasticity, Volume 2025, Issue 1, 2025.
Brain injury, including stroke and traumatic brain injury (TBI), is a leading cause of death and disability worldwide, and limited spontaneous neuroplasticity often results in persistent neurological impairments. Neuromodulation has the potential to enhance brain reorganization, but when targeting motor pathways, it might yield unsatisfactory ...

A Roadmap for Implanting Electrode Arrays to Evoke Tactile Sensations Through Intracortical Stimulation

Human Brain Mapping, Volume 45, Issue 18, December 15, 2024.
Functional imaging of the somatosensory cortex in people with spinal cord injury enabled planning for precise electrode array placement in the brain for a brain–computer interface. Stimulation through electrodes in the somatosensory cortex generated sensations of touch in digits that matched the functional imaging results used for placement.

Rat whisker motor cortex is subdivided into sensory-input and motor-output areas

Frontiers in Neural Circuits, 2013
Rodent whisking is an exploratory behavior that can be modified by sensory feedback. Consistent with this, many whisker-sensitive cortical regions project to agranular motor (MI) cortex, but the relative topography of these afferent projections has not ...
