Neurons that tracked a remembered smell turned up all over the mouse brain in a newly released dataset of 33,028 neurons recorded from 40 mice. The 2026 data paper makes those recordings free for other scientists to study how working memory works.1 Research Highlights Memory neurons in every well-sampled region: in all 34 brain regions …
In rats with toxin-damaged cerebellums, 4 weeks of the blood-pressure drug losartan reduced oxidative damage, inflammation and tissue injury. A nanoparticle version did better on several tissue and staining measures, but not on gene activity.1 Research Highlights A small rat experiment: 24 male rats in 4 groups of 6. Three groups received carbon tetrachloride (a …
Adding socioeconomic background to EEG brain recordings slightly improved how well a deep-learning model sorted 127 US university students by ADHD screening status. Accuracy rose on all 4 brain-recording tasks, but the gain was not statistically significant on any of them.1 Research Highlights About 9 in 10 classified correctly from EEG alone: tested on students …
Mice that only watched another mouse being attacked developed anxiety- and depression-like behavior, but milder and narrower changes than mice that were attacked themselves, according to a 2026 study in male mice.1 Research Highlights Both kinds of stress caused social avoidance: after 14 days, attacked mice and witness mice both spent less time near a …
University students with subthreshold depression, meaning real depressive symptoms that fall short of a major depression diagnosis, had stronger connections in 3 cingulate brain circuits and slightly higher levels of 3 inflammatory proteins than healthy students, according to a 2026 brain-imaging study from China.1 Research Highlights Stronger cingulate connections: resting brain scans of 126 students …
About 2 months after a concussion, adults had lower fiber density in a few white matter tracts linking the thalamus to the top of the brain, even though their thinking test scores looked normal. A 2026 study compared 39 people with mild traumatic brain injury to 28 people hurt in accidents without a head injury.1 …
Guanfacine, a non-stimulant ADHD medication, reduced hyperactivity in autistic children in a placebo-controlled trial. A 2026 review argues it may also steady prefrontal brain signaling and calm the brain’s immune cells, but that immune effect has never been tested with guanfacine itself.1 Research Highlights Hyperactivity fell in the largest autism trial: in 62 autistic children, …
