Longer action potential duration in the Purkinje network than in the ventricular myocardium delays retrograde activation of the human His‐Purkinje system

The Journal of Physiology, EarlyView.
Abstract figure legend Activation time (AT) maps from right ventricular apical pacing in a human ventricles model with longer action potential duration in the His‐Purkinje system (HPS) than in the myocardium (MYO). For pacing with a long S1S2 coupling interval (CI), the AT from the myocardial pacing site to the first AT of the HPS (ATMYO) is longer ...

A Novel Gain‐of‐Function ITPR1 Variant Associated With a Movement Disorder Characterized by Tremor and Dystonia

American Journal of Medical Genetics Part A, Volume 200, Issue 6, Page 1261-1266, June 2026.
ABSTRACT The 1,4,5‐trisphosphate receptor type 1 (ITPR1) gene encodes an endoplasmic reticulum calcium release channel, in which loss‐of‐function mutations have been associated with spinocerebellar ataxias and related neurological phenotypes. Only one gain‐of‐function mutation in the highly conserved suppressor domain of ITPR1 has been previously ...

Unveiling a New Link: Cholesterol Deficiency in Smith–Lemli–Opitz and Niemann–Pick C as a Driver of Ciliopathies

American Journal of Medical Genetics Part A, Volume 200, Issue 6, Page 1179-1191, June 2026.
ABSTRACT The ciliopathies are a group of genetic disorders caused by defective function of either the primary cilia (a large number) or the motile cilia (a much smaller number). These have been defined as diseases with mutations in genes encoding individual ciliary or cilia‐associated proteins.

Structural Characterization of Cardiac Free‐Running Purkinje Fibers Using Inhomogeneous Magnetization Transfer (ihMT): A Proof of Concept MRI‐Histology Approach

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
The cardiac Purkinje network is essential for synchronized ventricular activation but remains difficult to visualize with conventional MRI due to limited structural contrast. This study demonstrates that inhomogeneous magnetization transfer imaging provides enhanced contrast that differentiates free‐running Purkinje fibers, Purkinje‐Myocardial Junction,

Cerebellar models of associative memory: Three papers from IEEE COMPCON spring 1989 [PDF]

Three papers are presented on the following topics: (1) a cerebellar-model associative memory as a generalized random-access memory; (2) theories of the cerebellum - two early models of associative memory; and (3) intelligent network management and ...

Combination Versus Monotherapy in Acute Anti‐LGI1 Encephalitis: A Real‐World Dose Optimization Analysis

Neuropsychopharmacology Reports, Volume 46, Issue 2, June 2026.
Combined IVIg and 500 mg/day IVMP achieve superior efficacy over monotherapies in anti‐LGI1 encephalitis, with optimal safety. Higher‐dose IVMP (1000 mg) accelerates response but increases adverse events, particularly in diabetic patients. Cognitive deficits persist post‐treatment, necessitating long‐term management.

Transcranial Calcium Macro‐Imaging From the Auditory Cortex of Thy1‐Cre‐Driven GCaMP8 Transgenic Rats

Neuropsychopharmacology Reports, Volume 46, Issue 2, June 2026.
We generated Thy1‐Cre–driven GCaMP8 transgenic rats by mating Thy1‐Cre rats with knock‐in rats carrying a floxed GCaMP8‐STOP cassette in the β‐actin locus. Robust neuronal GCaMP8 expression enabled transcranial calcium imaging of the auditory cortex, establishing this model as a powerful tool for minimally invasive cortical macro‐imaging and functional

Dystrophinopathy with a DMD exon 49–50 deletion in a female patient who developed schizophrenia: An autopsy case

Psychiatry and Clinical Neurosciences Reports, Volume 5, Issue 2, June 2026.
Abstract Background Mutations in DMD affect not only muscles but also the brain. Cases of schizophrenia with DMD mutations have been described previously. Although female dystrophinopathy often has a milder phenotype, some affected females also have intellectual disabilities and psychiatric disorders.
