Topic: Transcranial ultrasound neuromodulation

Transcranial ultrasound neuromodulation (TUS) is a fast growing non-invasive brain stimulation method allowing reversible and local perturbation of the neuronal activity in superficial but also deep-brain structures. Although TUS efficiency has been shown at the circuit and behavioral levels, its precise impact on the neuronal tissue remains a subject of ongoing investigation. Using resting-state fMRI (rs-fMRI) and MRI spectroscopy (MRS), we characterized both the functional and metabolic effects of TUS on a subcortical structure, the amygdala.In two anaesthetized non-human primates, We select
