UrduChildren with chronic nausea and a condition known as orthostatic intolerance (OI) (dizziness when standing up) exhibit brain connectivity changes in areas related to sensory external and internal awareness resulting in over self-monitoring, according to a study published in the journal Neurogastroenterology & Motility.

‘Brain Surfing’: Ultrasound waves focused on prefrontal cortex elevate mood and change brain connectivity in human volunteers
A team of researchers at the University of Arizona has found that low-intensity ultrasound waves directed at a particular region of the brain’s prefrontal cortex in healthy subjects can elevate mood, and decrease connectivity in a brain network that has been shown to be hyperactive in psychiatric disorders. The method uses transcranial focused ultrasound (‘tFUS’), a painless, non-invasive technique to modulate brain function comparable to transcranial magnetic stimulation (‘TMS’), and transcranial direct current stimulation (‘tDCS’). This study shows, for the first time, a correlation between tFUS-induced mood enhancement, and reorganization of brain circuits.
