Individuals with #NeurofibromatosisType1 (#NF1) frequently exhibit significant deficits in visuospatial and visuomotor abilities compared with those without NF1. Results in Neuropsychology Review. Read more: bit.ly/4n3xueg #RareDisease #Neuropsychology
Neuroscience shows that memory retrieval is not a replay it’s a reconstruction. Hippocampal CA1 ensembles don’t fire identically during recall; they generate a probabilistic pattern that approximates the original encoding. #neuroscience
How the Brain Selects Between Perception and Memory Everyday behavior depends on the brain’s ability to shift attention seamlessly between external sensory inputs and internal mental representations. External attention helps us select and prioritize incoming stimuli, while internal attention guides memory, plans, and imagination. Both rely on overlapping frontoparietal networks, though internal attention uniquely engages additional prefrontal regions. Research shows these shifts incur measurable behavioral costs, hinting at underlying neural bottlenecks or competition. Yet, spatial attention mechanisms appear equally fast across domains, suggesting bottlenecks may emerge at later processing stages. Understanding these dynamics could improve models of flexible cognition and reveal targets for addressing attentional deficits in disorders.
Psychologist Leonard Sax: "Neuroscientists have known for many years that every human brain is characterized by a “fingerprint” of brain activity at rest, unique to that individual. The Stanford neuroscientists used artificial intelligence techniques to determine the fingerprint of every one of those young adults and then compared females with males. Did females differ from males? Was there overlap? The results were astonishing. These findings strongly suggest that what’s going on in a woman’s brain at rest is significantly different from what’s going on in a man’s brain at rest. salvomag.com/article/salvo7…
According to this study of post-mortem brain tissue, the proliferation of neural stem cells and neuroblasts is impaired & Newborn neuron maturation is differentially affected in individuals with psychiatric disorders. Also,the homeostasis of the dentate gyrus is altered
These findings are from a study in @FrontPsychol which recorded brain electrical activity in 36 university students as they were handwriting visually presented words using a digital pen and typewriting the words on a keyboard. frontiersin.org/journals/psych… 2/10
New study finds that people with a genetic risk for psychosis have an imbalance of glutamate and GABA neurotransmitters in their brains. This imbalance is associated with hippocampal atrophy, which may lead to the development of psychotic symptoms. The findings could lead to new treatments for psychosis by targeting the glutamate-GABA imbalance. #psychology 1/3
Autism and ADHD Brain Patterns Reveal Shared Biological Roots The study reveals that autistic traits — rather than formal diagnostic categories — map onto shared patterns of brain connectivity across children with autism and ADHD. Stronger autistic symptoms corresponded to increased coupling between frontoparietal and default-mode networks, a deviation from typical developmental patterns. These neural signatures also aligned with expression of genes involved in neural development, indicating a shared biological basis across conditions. The findings support a dimensional approach to understanding neurodevelopment, grounded in brain–gene mechanisms. neurosciencenews.com/autism-adhd-ge…
A catalyst in neuropsychology both in Canada and around the world, multi award-winning Dr. Brenda Milner has transformed our scientific understanding of the human brain—especially through detailed case studies of patients who underwent brain surgery.
With infantile spasms, every moment matters. Early diagnosis and treatment can help decrease the chance of developmental delay and future seizure disorders. Learn more: hubs.la/Q03WHLS00 #TimeIsBrain #ISAW2025 #PediatricCare @Child_neurology
