Molecular logic for cellular specializations that initiate the auditory parallel processing pathways.

The cochlear nuclear complex (CN), the starting point for all central auditory processing, encompasses a suite of neuronal cell types highly specialized for neural coding of acoustic signals. However, the molecular logic governing these specializations remains unknown. By combining single-nucleus RNA sequencing and Patch-seq analysis, we reveal a set of transcriptionally distinct cell populations encompassing all previously observed types and discover multiple hitherto unknown subtypes with anatomical and physiological identity.

Inflammatory disease in people with multiple sclerosis treated with immune checkpoint inhibitors.

This study evaluated disease activity in people with Multiple Sclerosis (PwMS) who received immune checkpoint inhibitors (ICIs) compared to PwMS not treated with ICIs. There were 108 PwMS included (27 PwMS+ICIs and 81 PwMS controls), matched on age, sex, disease duration, DMTs, and MS disease course. Of 27 PwMS+ICIs, one (4%) had a relapse and four (15%) developed new MRI lesions without clinical symptoms.

Aperiodic spectral slope tracks the effects of brain state on saliency responses in the human auditory cortex.

Alteration of responses to salient stimuli occurs in a wide range of brain disorders and may be rooted in pathophysiological brain state dynamics. Specifically, tonic and phasic modes of activity in the reticular activating system (RAS) influence, and are influenced by, salient stimuli, respectively. The RAS influences the spectral characteristics of activity in the neocortex, shifting the balance between low- and high-frequency fluctuations.

Improving Access to MS Care Through Technology.

People with multiple sclerosis (PwMS) experience many barriers to accessing multiple sclerosis (MS) care that lead to diagnostic delays, delayed treatment, interrupted care, and significant economic burden. These barriers include limited geographic healthcare resources, financial burden, physical limitations, and inequities within the healthcare system. Telemedicine has the potential to reduce these barriers and improve access to care.

A digital version of the nine-hole peg test: Speed may be a more reliable measure of upper-limb disability than completion time in patients with multiple sclerosis.

Background: A digital adaptation of the nine-hole peg test (9HPT) was developed with the potential to provide novel disability features for patients with multiple sclerosis (PwMS).

Objectives: The objectives were to evaluate the 9HPT features based on reliability, prognosis, and discrimination between treatment groups.

Methods: The MS partners Advancing Technology and Health Solutions (MS PATHS) cohort data were used to derive new features including completion time and speed.
