Title

Transcranial ultrasound stimulation relieves depression in mice with chronic restraint stress

Overall design

The aim of this study was to investigate the effects of transcranial ultrasound stimulating the dorsal raphe nucleus on antidepressant-like behaviors in mice. C57BL/6 mice were divided into the following 3 groups: (1) control group, (2) CRS group (CRS stress with sham transcranial ultrasound stimulating), and (3) CRS + transcranial ultrasound stimulating group (CRS stress with transcranial ultrasound stimulating). The CRS stress procedure lasted for 3 weeks (4 hours per day), then a head-mounted fixture was fixed on the skull of each successful mouse model by surgery. After one week of recovery, ultrasound stimulation was applied to freely behaving mice in the transcranial ultrasound stimulating group for 3 weeks. Liquid chromatography-mass spectrometry is performed to quantitatively detect the concentration of serotonin in the dorsal raphe nucleus.
