Medical Xpress / Common neuroscience sensors sometimes get their signals crossed
Cells in the brain communicate in different ways. The classical mode involves tight connections between individual cells that signal only to each other. But over the last decade, new tools have allowed scientists to focus ...
Medical Xpress / Language models identify psychiatric symptoms nearly as accurately as early-career clinicians
A study led by the Central Institute of Mental Health (CIMH) provides initial evidence that large language models can identify complex psychopathological findings in transcripts of psychiatric interviews with accuracy comparable ...
Medical Xpress / Study uses living human brain tissue to map how electric stimulation affects neurons and genetic activity
Neurons that once encoded a person's memories are now helping researchers identify genetic targets that may one day help preserve memory and slow cognitive decline in others.
Medical Xpress / AI companions may worsen loneliness for vulnerable users
AI companions are becoming increasingly popular, with millions of users forming deep connections with persona-based chatbots and simulated AI partners. But if you're considering leaning on an AI companion for emotional support, ...
Medical Xpress / New model maps where HIV is concentrated and the disease is more advanced
A new biostatistical modeling approach has the potential to support health decisions by pinpointing where HIV is concentrated and where people living with HIV are showing signs of severe immune suppression or delayed treatment. ...
Medical Xpress / Early split in brain precursors creates two neuron lineages, mouse study finds
The cerebral cortex is densely packed with different nerve cells that enable us to perceive, think and act. Yet how these cell types arise as the brain develops is still not fully understood. Irene Varela-Martínez, a postdoctoral ...
Medical Xpress / Cancer Dependency Map now includes next-generation 3D cancer models
For nearly a decade, the Cancer Dependency Map, or DepMap, at the Broad Institute has helped scientists uncover new cancer dependencies—the genetic changes some cancers need to thrive that can potentially be targeted by new ...
Medical Xpress / International project delivers hundreds of next-generation models for cancer research
Ten years and thousands of patient samples later, the National Cancer Institute (NCI) has published its results from the Human Cancer Model Initiative (HCMI) on the development of 665 organoid models of 25 types of cancer ...
Medical Xpress / Pretrained AI could help clinics analyze brain MRIs with few labeled scans
When it comes to medical imaging, a chatbot doesn't know its backside from its elbow. Or, at least, it can't tell a spine from a knee. But if a Boston University research team is successful, a smarter AI system for evaluating ...
Medical Xpress / IL-1 pathway may stop Candida fungus from turning fatal in weakened immunity
An immune pathway has been discovered that prevents a normally harmless fungus from developing into a fatal infection. The King's College London study, published in Nature Microbiology, provides the first potential clue as ...
Medical Xpress / Why laughter can trigger sudden muscle weakness in people with narcolepsy
Narcolepsy is a chronic neurological condition characterized by disruptions in the regulation of sleep-wake cycles. People with this condition often experience extreme sleepiness during the day and, in some cases, a sudden ...
Medical Xpress / Cannabis-derived THC shows promise for treating PTSD-related nightmares
Drastic or even life-threatening events can have lingering effects, like an echo. This is referred to as post-traumatic stress disorder (PTSD). The brain is unable to process these overwhelming experiences and stores the ...
