MRI Tracks Hippocampal Damage and Recovery in Rat Epilepsy Model
A longitudinal study in rats reveals acute hippocampal volume loss after status epilepticus, followed by partial recovery over 30 days.
Activities Counter Negative Affect in Depressed, Anhedonic Youth
Real-world data show leisure and social company improve mood primarily by decreasing negative affect, not by increasing positive affect.
Adolescent Nicotine Rewires Brain Circuitry to Boost Opioid Reward in Mice

Peri-Ictal MRI Abnormalities Predict 60% Seizure Risk After Status Epilepticus
Transient DWI and FLAIR changes within 48 hours of a first status epilepticus episode identify patients at high risk for epilepsy.
Lactate Enzyme Overexpression Enhances Remyelination in Animal Models
Restoring glycolysis and lactate production in oligodendrocyte precursors overcomes epigenetic silencing to stimulate myelin repair.
