Transcranial magnetic stimulation of the occipital cortex interferes with foot movements in acquired but not congenitally blind individuals
Abstract Research has shown that the occipital cortex can be reorganized and repurposed for nonvisual perception and cognitive functions following visual loss in blind individuals. However, no studies have directly examined the involvement of the visual cortex in motor function. Here, we show that a rhythmic foot movement performed by acquired blind individuals can be disrupted by transcranial magnetic stimulation (TMS) to their primary and secondary visual cortex (V1/V2).
Gray matter volume increase in the retrosplenial/posterior cingulate cortices of blind soccer players
Abstract Spatial navigation is a crucial brain function that occurs when an individual moves from one location to another. This function normally relies on vision, and the retrosplenial/posterior cingulate cortices (RSC/PCC) and parahippocampal cortex (PHC) play crucial roles. However, an extraordinary adaptation can be observed in blind soccer players, where the human brain can perform spatial navigation without vision.
Theoretical proposal for restoration of hand motor function utilizing plasticity of motor-cortical interhemispheric interaction
Abstract After stroke, the poorer recovery of motor function of upper extremities compared to other body parts is a longstanding problem. Based on our recent functional MRI evidence on healthy volunteers, this perspective paper proposes systematic hand motor rehabilitation utilizing the plasticity of interhemispheric interaction between motor cortices and following its developmental rule.
Younger adult brain utilizes interhemispheric strategy of recruiting ipsilateral dorsal premotor cortex for complex finger movement, but not aging brain
Abstract The ipsilateral sensorimotor cortices (dorsal premotor cortex [PMd], primary motor cortex [M1], primary somatosensory cortex [S1], and superior parietal cortex of Area 2) are often activated when the healthy younger and older adult brains perform complex finger movements.
Structural and functional features characterizing the brains of individuals with higher controllability of motor imagery
Abstract Motor imagery is a higher-order cognitive brain function that mentally simulates movements without performing the actual physical one. Although many studies have dealt with motor imagery, neural bases that determine individual differences in motor imagery ability are not well understood.
