Distributed brain-spinal cord dynamics during micturition revealed by functional ultrasound imaging

This study uses functional ultrasound imaging to map brain and spinal cord activity during micturition in rats, revealing region-specific hemodynamic responses and decoding bladder pressure dynamics.

Single-chip End-to-End Ingestible Electronics for Gut Neurotransmitter Sensing

This paper develops an ingestible pill for real-time in vivo sensing of serotonin and dopamine in the gut using a fully integrated electrochemical sensor and ASIC.

Human spinal cord activation during filling and emptying of the bladder

This study uses functional ultrasound imaging to observe spinal cord activity during bladder filling and emptying, identifying pressure-responsive regions correlated with bladder pressure.

Immediate and Long-Term Electrophysiological Biomarkers of Antidepressant Behavioral Effects After Subanesthetic Ketamine and Medial Prefrontal Cortex Deep Brain Stimulation Treatment

This study examines electrophysiological biomarkers of antidepressant effects from ketamine and mPFC DBS in rats, finding correlations between specific brain activity patterns and behavioral improvements.

Comparison of image registration techniques in functional ultrasound imaging

This study compares image registration techniques for functional ultrasound imaging, finding that Imregdeform provides the best alignment of 2D fUSI brain data.

Frequency- and circuit- specific effects of septohippocampal deep brain stimulation in mice as measured by functional ultrasound imaging.

This study uses functional ultrasound imaging to show that septohippocampal DBS at theta frequency increases hippocampal CBV after stimulation offset, unlike high-frequency DBS.
