Levodopa induced dyskinesia severity is linked to distinct microstructural alterations in nigrostriatal and brainwide neural circuits

This study investigates how L-DOPA-induced dyskinesia (LID) relates to microstructural changes in brain circuits, finding brainwide alterations beyond the nigrostriatal system.

Identification of low threshold off-target activation pathways during stimulation of carotid baroreceptor afferents in swine.

This study identifies off-target neural pathways activated during carotid baroreceptor stimulation in swine, contributing to side-effects of baroreflex activation therapy.

Assessing changes in whole-brain structural connectivity in the unilateral 6-hydroxydopamine rat model of Parkinson's Disease using diffusion imaging and tractography

This study uses diffusion imaging and tractography to analyze structural connectivity changes in a rat model of Parkinson's Disease, identifying lesion-specific and compensatory neural networks.

Epidural Spinal Cord Recordings (ESRs): Sources of Artifact in Stimulation Evoked Compound Action Potentials

This study identifies and characterizes sources of artifact contaminating evoked compound action potentials (ECAPs) in epidural spinal cord recordings, highlighting challenges in distinguishing neural signals from artifacts in a swine model.

μECoG Recordings Through a Thinned Skull

This paper demonstrates the acute and chronic performance of optically transparent μECoG grids on a thinned skull, showing stable impedances and reliable optogenetic activation and spatially distinct recordings.

Is Vagus Stimulation Brain Washing?

This study shows that cervical vagus nerve stimulation increases cerebrospinal fluid penetration into the brain, suggesting potential clinical implications for CNS disorders.
