We are very excited to feature a January issue Brain article, where we speak with senior author Dr Lasse M Giil entitled: Impaired glucose utilization in the brain of patients with delirium following hip fracture. Delirium is a common condition with significant impact on patient outcome. This episode discussed potential intrinsic brain mechanisms that may underly delirium. The team explores the evidence that delirium is more than just a systemic process that extends into the brain but may involve pathophysiological alterations of brain function. Listen to how this may change clinical practice.

In this episode we speak with Fu-Chin Liu, senior author of the article entitled: Speech- and language-linked FOXP2 mutation targets protein motors in striatal neurons. This article explores a potential genetic basis for disordered speech by a mutation in the transcription factor FOXP2. This was discovered in KE family members with speech disturbances was a landmark example of the genetic control of vocal communication in humans. The author and colleagues examine an animal model of the KE family FOXP2^R553H mutation to explore cellular pathomechanisms involving intracellular dynein-dynactin ‘protein motors’ in the striatum.

In this episode we speak with Josef Parvizi, senior author of the article entitled: Multisite thalamic recordings to characterize seizure propagation in the human brain. This article explores the role of the thalamus in seizure propagation and how multi-site intracranial electrode recordings identify new and unexpected findings regarding which thalamic nuclei may have the earliest involvement  in seizure propagation.

In this episode we speak with Ted Price, senior author of the article entitled: RNA profiling of human dorsal root ganglia (DRG) reveals sex differences in mechanisms promoting neuropathic pain. This article explores exciting findings around differences in the DRG transcriptome which were only apparent when stratifying participants by sex and how these differences may inform mechanistic targets for neuropathic pain.

In this episode we speak with Philip Insel, lead author of the article entitled: Tau positron emission tomography in preclinical Alzheimer’s disease. The article explores the utility of tau PET imaging in three independent, large cohorts of cognitively normal individuals with high levels of amyloid (on PET imaging). We discuss specific areas of the brain with high tau concentration and how this differs from the traditional Braak model from neuropathology data. Philip also details how tau PET imaging can play a role in clinical trials.

In this episode, we speak with Hideaki Nishihara and Britta Engelhardt, lead authors of the article entitled: Intrinsic blood–brain barrier dysfunction contributes to multiple sclerosis pathogenesis. This was a transcontinental recording with our guests dialing in from Japan and Europe. The article explores blood-brain barrier dysfunction as a pathogenic process of multiple sclerosis. The authors discuss the use of a novel in vitro model of the blood-brain barrier which was designed to capture the activity of adhesion molecules involved in leukocyte trafficking.
