Anti-Anxiety and Hallucination-Like Effects of Psychedelics Mediated by Distinct Neural Circuits

Andy Fell — November 14, 2024 - 10:06am

New research suggests that it could be possible to separate treatment from hallucinations when developing new drugs based on psychedelics. The anti-anxiety andhallucination-inducing qualities of psychedelic drugs work through different neural circuits, according to research using a mouse model. The work is published Nov. 15 in Science.

Brain-Computer Interface Allows Man With ALS to ‘Speak’

A brain-computer interface (BCI) developed by �ٺ��Ƶ Health accurately translates brain signals into speech. The device implanted in the brain of a man with ALS is the most accurate system of its kind.

New Method Tracks How Psychedelics Affect Neurons in Minutes

Andy Fell — August 05, 2024 - 10:22am

Researchers at the University of California, Davis have developed a rapid, noninvasive tool to track the neurons and biomolecules activated in the brain by psychedelic drugs. The protein-based tool, which is called Ca^2+-activated Split-TurboID, or CaST, is described in research published in Nature Methods.

Exploring Early Stage Alzheimer’s Disease

Research in nonhuman primates is opening the possibility of testing treatments for the early stages of Alzheimer’s and similar diseases, before extensive brain cell death and dementia set in. A study published June 21 in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association shows up to a six-month window in which disease progress could be tracked and treatments tested in rhesus macaques.

COVID-19 Virus Infects Neurons, Induces Inflammation in the Brains of Rhesus Macaques

Andy Fell — October 13, 2022 - 11:00am

SARS-CoV-2, the COVID-19 virus, caused significant neuron damage and inflammation within a week of infection in rhesus macaque monkeys, according to a new study. The researchers from the California National Primate Research Center at the University of California, Davis, also discovered that aged monkeys with Type 2 diabetes experienced worse virus-induced neurological damage. The findings, published in Cell Reports Oct.

Clinical Trial Aims to Develop New Methods to Restore Speech With Brain-Computer Interface

Andy Fell — August 19, 2022 - 10:19am

�ٺ��Ƶ Health is recruiting people for a clinical trial with the goal of building a “neurological prosthesis” for restoring speech to people who have lost — or are losing — the ability to speak. The research is aimed at people who have neurological injuries or progressive neurological diseases, such as spinal cord injury, stroke and amyotrophic lateral sclerosis, or ALS.

Air Quality Impacts Early Brain Development

Katherine E Kerlin — June 17, 2020 - 10:15am

Researchers at the University of California, Davis, have found a link between traffic-related air pollution and an increased risk for changes in brain development relevant to neurodevelopmental disorders. Their study, based on rodent models, corroborates previous epidemiological evidence showing this association.
