PUTTING CRAVING INTO CONTEXT: EFFECTS OF PERCEIVED SMOKING OPPORTUNITY ON THE NEURAL RESPONSE TO CIGARETTE CUE EXPOSURE [PDF]

, 2005
Recent years have seen the emergence of research applying functional neuroimaging to the study of cue-elicited drug craving. This research has begun to identify a distributed system of brain activity during drug craving.

Whole‐Brain Fractional Anisotropy, Centered on the Superior Longitudinal Fasciculus, Is Positively Correlated With Urban Aesthetic Perception

Brain and Behavior, Volume 16, Issue 5, May 2026.
This study examines the association between urban aesthetic perception and white matter microstructure in healthy adults. Diffusion tensor imaging reveals that both whole‐brain fractional anisotropy and superior longitudinal fasciculus integrity are positively related to subjective evaluations of urban aesthetic quality, suggesting that everyday ...

White Matter Tract Alterations in Bipolar Disorder: A Systematic Review and Meta‐Analysis of Diffusion Tensor Imaging Studies

Brain and Behavior, Volume 16, Issue 5, May 2026.
This systematic review and meta‐analysis synthesizes diffusion tensor imaging evidence of white matter microstructural abnormalities in bipolar disorder. Across published studies, patients with bipolar disorder showed reduced fractional anisotropy in several major white matter tracts, including the corpus callosum, cingulum bundle, corona radiata ...

Regional Brain Activity Alterations in Social Anxiety Disorder Revealed by Seed‐Based d Mapping With Permutation of Subject Images

Brain and Behavior, Volume 16, Issue 5, May 2026.
This SDM‐PSI meta‐analysis identified consistent regional brain activity alterations in social anxiety disorder, including hyperactivity in the left superior parietal gyrus, right cerebellum, and right supramarginal gyrus, and hypoactivity in the left insula and right supplementary motor area, with age and symptom severity modulating specific regions ...

Correspondence of Basal Forebrain Resting‐State Functional Connectivity and Cerebral Glucose Metabolism Alterations With Neurotransmitter Maps in Alzheimer's Disease

CNS Neuroscience &Therapeutics, Volume 32, Issue 5, May 2026.
Altered functional connectivity of basal forebrain subregions (Ch1‐3, Ch4) and widespread cerebral hypometabolism were identified in Alzheimer's disease using simultaneous PET/MRI. Spatial correspondence with normative neurotransmitter receptor and transporter maps suggested that serotonergic and dopaminergic systems may contribute to AD‐related ...

Natural Products as the Modulators of Gut Microbiota: A Pool for the Development of New Treatment Against Obesity?

Food Frontiers, Volume 7, Issue 3, May 2026.
Natural compounds regulate gut microbiota by improving microbial balance and increasing probiotics, which boost short‐chain fatty acid production to alleviate insulin resistance and inflammation. Additionally, they stimulate appetite‐suppressing hormones through bile acid signaling, while inhibiting pathogenic bacteria to repair intestinal barrier ...

Directed Communication in Theta and Alpha Networks Supports Content Handling in Working Memory

Human Brain Mapping, Volume 47, Issue 7, May 2026.
We examined mental rotation and delineated the role of directed communication in theta and alpha band activity in cortical networks. ABSTRACT Executive functions enable flexible control of behavior by dynamically coordinating perception, memory, and action.

No Evidence of Moderated Impulsivity Following Administration of the IMPase Inhibitor Ebselen in Healthy Adults

Human Psychopharmacology: Clinical and Experimental, Volume 41, Issue 3, May 2026.
ABSTRACT Objective Impulsivity is a transdiagnostic risk factor for numerous health morbidities and is strongly associated with early relapse and poor treatment outcomes in addictions and mood‐disorders. Lithium carbonate can be helpful in moderating the impulsive behaviors associated with mania, possibly mediated by reduced myo‐inositol activity ...
