Credit: PixabayIt’s been just under two years since OpenAI introduced ChatGPT to the public, allowing anyone online to collaborate with an AI on tasks ranging from poetry and schoolwork to drafting letters for their landlord.Today, ChatGPT is just one of several advanced large language models (LLMs) capable of responding to basic queries in a...
Credit: PixabayNeurons, the brain’s essential cells, form intricate networks by exchanging signals, enabling learning and adaptation. Researchers at Delft University of Technology (TU Delft) in the Netherlands have created a 3D-printed environment that closely resembles real brain tissue. Using nanoscale pillars, they replicate the soft, fibrous structure that supports neurons. This innovation provides a...
Credit: PixabayChildren with attention deficit hyperactivity disorder (ADHD) are not lazy, undisciplined, or lacking manners. Instead, their brains develop and function differently, marked by unique neurological activity patterns and neurochemical imbalances. These differences classify ADHD as a neurodevelopmental disorder rather than a behavioral issue.The Neurological Basis of ADHDThe neurological variations in ADHD manifest as...
Credit: PixabayYour brain can still produce new neurons in adulthood, but how do these rare additions support cognitive function?Neurons, the cells responsible for brain function, are mostly formed before birth. While early life sees the bulk of brain development, certain regions continue generating neurons into adulthood, albeit at a slower pace. Scientists debate whether...
Memory storage and retrieval may be able to be targeted thanks to new discoveryBaylor College of MedicineRecent research into how "brain stars" (astrocytes) store memories has reshaped our understanding of memory retention in the brain.Previous Beliefs About Memory and NeuronsScientists at Baylor College of Medicine have been examining the role of astrocytes, star-shaped cells...
A study published in Neurology suggests that closely following the MIND diet may lower the risk of cognitive impairment, with a stronger effect observed in women and Black participants. While the study shows an association between the diet and reduced risk, it does not prove causation. Credit: PixabayA study published in Neurology, the journal...
No part of the body is immune to microplastic contamination.Image credit: SIVStockStudio/Komsan Loonprom/Shutterstock.com; modified by IFLScienceMicroplastics are omnipresent, wreaking havoc on the environment and infiltrating our bodies, including the brain. A new preprint study, not yet peer-reviewed, raises concerns about the extent of microplastics in the human brain and potential health risks.The study analyzed...
Some parts of the brain tend to atrophy and deform in concert with other regions. Credit: Zephyr/SPLA comprehensive analysis of nearly 50,000 brain scans has identified five unique patterns of brain atrophy linked to aging and neurodegenerative diseases. The study also connected these patterns to lifestyle factors such as smoking and alcohol consumption, as...
Credit: PixabayNeuroscientists believe they have pinpointed the extensive neural network that fuels the brain's creativity. Unlike specific movements or sensory responses, creative thinking is not limited to a single area of the brain's outer cortex. However, researchers from Baylor College of Medicine have identified the brain circuits crucial to certain types of creative thought.When...
Selective serotonin releasing agent is not negated by 5-HT1A supersensitivity, resulting in a rapid onset of pro-serotonergic activity. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-50394-xAccording to a new study in Nature Communications, increasing serotonin can alter how people learn from negative information and enhance their response to it.Researchers from the University of Oxford's Department of Psychiatry and...
