Dynamic Brain State Alterations in Narcolepsy: A Hidden Markov Model Approach to Thalamocortical Instability and Symptom‐Specific Neural Correlates

Brain and Behavior, Volume 16, Issue 4, April 2026.
This graphical abstract illustrates how Hidden Markov modeling of functional magnetic resonance imaging (fMRI) reveals five dynamic brain states in narcolepsy type 1 (NT1), with reduced thalamocortical arousal (State 1) and elevated REM‐like limbic‐motor (State 4) and reward‐introspection (State 5) states linking to hallucinations and daytime ...

Reduced Whole‐Brain Network Segregation and Dorsal Anterior‐Cingulate Cortex Neurochemical Alterations in Chronic Smokers

Brain and Behavior, Volume 16, Issue 4, April 2026.
Chronic smokers exhibited less segregated brain networks and shifts in centrality from executive to reward‐related regions. Additional spectroscopy measures revealed lower tNAA in the dorsal anterior cingulate cortex, highlighting network‐level and neurochemical alterations that may underlie smoking‐related vulnerability.

The Phase‐Amplitude Coupling Induced by Drug Cues in Individuals With Methamphetamine Use Disorder During Withdrawal

Brain and Behavior, Volume 16, Issue 4, April 2026.
Whole‐brain PAC and directed PSI analyses during a drug‐cue task in abstinent patients with methamphetamine use disorder revealed that drug‐related stimuli enhanced prefrontal and centro‐parietal PAC but disrupted top–down information flow from prefrontal to occipital regions.

Claustrum Sign in Hashimoto Encephalopathy Presenting With New Onset Refractory Status Epilepticus (NORSE): First Report of a Rare Phenotype

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT The presence of the bilateral claustrum sign in new‐onset refractory status epilepticus (NORSE) should prompt consideration of Hashimoto's encephalopathy, even without thyroid dysfunction. Early recognition and corticosteroid therapy can be lifesaving, emphasizing an autoimmune‐inflammatory mechanism underlying this rare presentation.

Pain-Related Nucleus Accumbens Function

, 2019
The nucleus accumbens (NAc) has been implicated in sleep, reward, and pain modulation, but the relationship between these functional roles is unclear. This study aimed to determine whether NAc function at the onset and offset of a noxious thermal stimulus is enhanced by rewarding music, and whether that effect is reversed by experimental sleep ...
