Networks in the parietal and premotor cortices enable essential human abilities regarding motor processing, including attention and tool use. Even though our knowledge on its topography has steadily increased, a detailed picture of hemisphere-specific integrating pathways is still lacking. With the help of multishell diffusion magnetic resonance imaging, probabilistic tractography, and the Graph Theory Analysis, we investigated connectivity patterns between frontal premotor and posterior parietal brain areas in healthy individuals.

- - The review evaluated how repetitive transcranial magnetic stimulation (rTMS) affects unilateral spatial neglect (USN) in post-stroke patients, revealing significant improvements through various testing methods (e.g., line bisection test, cancelation test).
- - It was found that excitatory rTMS on the same side of the brain as the stroke is generally more effective in reducing neglect symptoms compared to inhibitory rTMS on the opposite side.
- - Additionally, rTMS was particularly beneficial for patients at the acute stage post-stroke (within 3 months), suggesting that earlier treatment could lead to better recovery outcomes for USN.
Introduction: Transcranial Magnetic Stimulation (TMS) can modulate fronto-striatal connectivity in the human brain. Here Positron Emission Tomography (PET) and neuro-navigated TMS were combined to investigate the dynamics of the fronto-striatal connectivity in the human brain. Employing 18F-DesmethoxyFallypride (DMFP) - a Dopamine receptor-antagonist - the release of endogenous dopamine in the striatum in response to time-spaced repeated bouts of excitatory, intermittent theta burst stimulation (iTBS) of the Left-Dorsolateral Prefrontal Cortex (L-DLPFC) was measured.
