Do auditory deviants evoke cortical state changes under anaesthesia? A proof‐of‐concept study

open access: yesExperimental Physiology, EarlyView.
Abstract Context‐dependent sensory processing within the predictive coding framework relies on detecting mismatches between incoming stimuli and internal predictive models. Sensory deviants elicit prediction errors, seen as enhanced neural responses, that update these models and influence attention and behaviour.

Evaluation of GABAergic and Glutamatergic Levels in the Dorsal Anterior Cingulate Cortex of Patients With Bipolar Disorder: A Cross‐Sectional 1H‐MRS Study

open access: yesNeuropsychopharmacology Reports, Volume 46, Issue 1, March 2026.
Using 1H‐MRS with MEGA‐PRESS, we found no significant differences in dACC GABA or Glx levels between bipolar disorder patients and controls. However, GABA levels were higher in lithium‐treated patients, suggesting medication effects on GABAergic tone. ABSTRACT Background Imbalances between excitatory and inhibitory (E/I) neurotransmitters in the brain ...

Developmental trajectories of visual temporal integration and segregation in children with and without developmental dyslexia

open access: yesBritish Journal of Developmental Psychology, Volume 44, Issue 1, Page 146-165, March 2026.
Abstract In the present study, 43 Italian school‐age children (age range = 7–14 years, 16 females) with (N = 19) and without DD (N = 24) were presented with pairs of visual displays separated by varying interstimulus intervals and performed either a temporal integration or segregation task despite an identical visual input.

Lesion Location and Functional Connections Reveal Cognitive Impairment Networks in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, Volume 13, Issue 2, Page 242-255, February 2026.
ABSTRACT Objective Cognitive impairment, fatigue, and depression are common in multiple sclerosis (MS), potentially due to disruption of regional functional connectivity caused by white matter (WM) lesions. We explored whether WM lesions functionally connected to specific brain regions contribute to these MS‐related manifestations.

Autosomal Recessive Spastic Ataxia of Charlevoix‐Saguenay in Two Half‐Siblings

open access: yesAnnals of Clinical and Translational Neurology, Volume 13, Issue 2, Page 413-417, February 2026.
ABSTRACT Autosomal recessive spastic ataxia of Charlevoix‐Saguenay (ARSACS) is caused by biallelic pathogenic variants in the SACS gene. We report the clinical, radiologic and neurophysiologic features of a pair of half‐siblings who presented with progressive cerebellar ataxia, peripheral neuropathy and upper motor neuron signs.

Deep cervical lymphatic–venous anastomosis attenuates cognitive dysfunction and biomarker abnormalities in severe Alzheimer's disease: A prospective single‐arm study

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION This study evaluated the efficacy of deep cervical lymphatic–venous anastomosis (dcLVA) for severe Alzheimer's disease (AD). METHODS A total of 139 severe AD patients undergoing dcLVA were enrolled, and changes in cognitive function and biomarkers were evaluated by comparing preoperative measures with postoperative outcomes over a

Associations between accelerometer‐derived physical activity complexity, cognitive function, and plasma biomarkers of Alzheimer's disease

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION While higher physical activity (PA) levels are linked to lower Alzheimer's disease (AD) risk, traditional PA measures overlook temporal activity patterns. METHODS We developed the activity complexity measure in 164 older adults (mean age = 65.3 years) who completed wrist‐worn accelerometry and neuropsychological tests.

Relationship between locus coeruleus and slow‐wave sleep in aging and Alzheimer's disease

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Sleep disruption, particularly loss of slow‐wave sleep (SWS), is common in Alzheimer's disease (AD), but its neurobiological underpinnings remain unclear. We investigated whether locus coeruleus (LC) integrity relates to SWS across the AD continuum and whether sex and perivascular spaces (PVSs) modify these associations.
