Sternal Vibration Plus Mindfulness Improves Body Awareness, White Matter in Trauma
A study in trauma-exposed adults found sternal vibration combined with mindfulness meditation enhanced interoceptive awareness and increased neurite.
Simvastatin Rescues Cognitive Impairment in Alzheimer's Model via Epigenetic and Synaptic Pathways
A preclinical study in mice identifies specific molecular mechanisms by which simvastatin may improve cognitive function in Alzheimer's disease.
Fentanyl Differentially Modulates Dopamine Patterns, Impairing Reward Seeking in Mice
Acute fentanyl administration simultaneously increases tonic dopamine while reducing phasic dopamine responses to non-drug reward cues.
THC Disrupts Rat Fear Memory via Sex-Specific Microglial and Receptor Pathways
In male rats, THC requires microglial recruitment and dual receptor signaling, while female effects depend on the estrous cycle and CB1.
Sleep Efficiency Improvements Drive Antidepressant Response to CBT for Insomnia
A mechanistic trial shows that objective sleep gains, not changes in brain emotional circuits, correlate with improved mood symptoms.
Brain FAAH Levels Rise During Short-Term Cannabis Abstinence
PET imaging shows enzyme increases in the ventral striatum correlate with depression and impulsivity during early withdrawal.
Prenatal SRI Exposure Linked to Altered Fetal Brain and Placental Growth
MRI data show reduced hippocampal volume and cortical folding in fetuses exposed to antidepressants or high maternal depression scores.
Involuntary Prenatal Oxycodone Exposure Increases Addiction Risk in Rat Offspring
A rat study shows that non-contingent maternal opioid use leads to higher motivated drug-seeking in adult progeny than voluntary intake.
Type 2 Diabetes Linked to Reduced Effort-Based Motivation Unchanged by Semaglutide
A computational study finds metabolic dysfunction drives a cognitive shift toward energy conservation regardless of GLP-1 agonist use.
Schizophrenia Subtype Shows Low Striatal Dopamine and Iron Accumulation
A frontotemporal dementia-like phenotype in schizophrenia patients challenges the universal hyperdopaminergic model of the disease.
Luvadaxistat Fails to Improve Schizophrenia Cognition in Phase 2 Trial
The ERUDITE study found no significant cognitive benefit from adding the D-amino acid oxidase inhibitor to stable antipsychotic therapy.
