Interhemispheric inhibition can be manipulated by directly and bidirectionally modulating the bilateral sensorimotor excitabilities in a spatially bivariate Brain-Computer Interface-based neurofeedback paradigm.
A combined rehabitative protocol after stroke in the mouse normalizes transcallosal inhibition and promotes "true recovery" of forelimb motor function.
Humans showed the most widespread asymmetric connectivity between the inferior parietal lobule subregions and the rest of the brain compared to macaques and chimpanzees, which shapes hemispheric specialization in primates.
A complementary relationship exists between the hemispheric lateralization of inhibitory control (typically right) and speech (typically left), as observed in typically and atypically lateralized left-handed individuals.

In the brain at rest, the degree of coordinated activity within the motor network is inversely related to levels of the inhibitory transmitter GABA in primary motor cortex.
Excitation of contralesional cortex after stroke suppresses the expression of genes related to plastic neuronal reintegration and accordingly modulates perilesional remodeling and functional network communication at local and global scales.

Dimensionality reduction techniques reveal how the organization of neurotransmitter receptor and transporter co-expression in the human brain may bridge the gap between brain structure and function.
Studying the activity of cortical neurons in rats reveals the subcellular effects of transcranial magnetic stimulation, which is used for the non-invasive treatment of a variety of brain disorders.

An electrode-wise encoding model based on physiological recordings from the cortical surface revealed a striking hemispheric asymmetry where the encoding of ipsilateral movement was stronger in the left hemisphere compared to the right hemisphere.
Novel evidence for a role of feedback in the perception of uniform surfaces in the human brain suggests that feedback already re-enters at an early visual processing stage.
