Summary: Neurons generated during adult neurogenesis in the dentate gyrus continue to grow and mature over many months, becoming larger and more complex than neurons born in infancy. These long-maturing adult-born neurons likely contribute disproportionately to hippocampal plasticity and may serve distinct functional roles throughout life. Source: SfN Adult-born neurons continue developing for months and … Read more

Summary: Targeted sleep therapy for autistic adults shows encouraging results, with reductions in insomnia symptoms and related anxiety. Source: La Trobe University La Trobe University researchers have completed the first pilot study worldwide testing a sleep-focused intervention specifically adapted for autistic adults. The findings point to meaningful reductions in insomnia severity and improvements in co-occurring … Read more

Summary: Repeated listening to personally meaningful music promotes brain plasticity and improves cognitive performance in people with mild cognitive impairment and early-stage Alzheimer’s disease. Source: University of Toronto Researchers at the University of Toronto and Unity Health Toronto report that repeated exposure to personally meaningful music can induce beneficial changes in the brain and improve … Read more

Summary: Researchers have used CRISPR gene-editing to reprogram stem cells so they can detect joint inflammation and produce an anti-inflammatory biologic to combat arthritis. Source: WUSTL. Goal is a vaccine-like therapy that targets inflammation in joints Scientists have engineered mouse stem cells using CRISPR/Cas9 genome editing to create cells that sense inflammatory signals and respond … Read more

Summary: Researchers examined whether people are judged more positively and even rewarded at the ballot box when their name matches the shape of their face. Source: Springer. New research finds that a well-matched name and face can help a politician win more votes. Researchers David Barton and Jamin Halberstadt of the University of Otago in … Read more

Different regions of the brain specialize in processing distinct aspects of our sensory experiences. How those cortical areas communicate and route sensory signals to support perception and behavior has been a longstanding question in neuroscience. By studying touch in mice, researchers at the University of Zurich demonstrate that the flow of sensory information from one … Read more

Summary: Among veterans with traumatic brain injury (TBI), poor sleep was linked to larger MRI-visible perivascular spaces and an increase in persistent post-concussive symptoms. Source: Oregon Health and Sciences University Sound, restorative sleep appears vital to recovery after traumatic brain injury, according to a new study of military veterans. Published in the Journal of Neurotrauma, … Read more

Summary: Researchers apply a mathematical framework to clarify healthy brain function and to explain how neuropsychiatric disorders may arise. They propose that problems in processing prior beliefs can cause incorrect interpretations of sensory data, producing pathological perceptions and behaviors. Source: Frontiers Every second, our brains receive a flood of information from the five senses. To … Read more

Summary: New research shows that listening to and practicing music can slow cognitive decline in older adults by stimulating increases in grey matter in key brain regions. Source: University of Geneva Normal aging often brings gradual cognitive decline. But can targeted activities help preserve mental abilities? Researchers from the University of Geneva (UNIGE), HES‑SO Geneva … Read more

Summary: New preclinical research from Weill Cornell Medicine indicates that dysfunction in astrocytes—non-neuronal support cells in the brain—may drive cognitive decline and memory loss in dementia. The study links accumulation of the protein TDP-43 in astrocytes to abnormal antiviral immune activity, excessive chemokine signaling, neuronal hyperactivity, and progressive memory impairment.
