Brain implants predicted to revolutionize the future of language learning.

In the field of optogenetics, scientists investigate the activity of neurons in the brain using light. A team led by Prof. Dr. Ilka Diester and Dr. David Eriksson from the Optophysiology Laboratory at the University of Freiburg has developed a new method to simultaneously conduct laminar recordings, multifiber stimulations, 3D optogenetic stimulation, connectivity inference, and behavioral quantification on brains. Their results are presented in Nature Communications. “Our work paves the way for large-scale photo-recording and controlled interrogation of fast neural communication in any combination of brain areas,” Diester explains. “This can help us unravel the rapid and multilayered dialogs between neurons that maintain brain function.”

The research group, in collaboration with Dr. Patrick Ruther of the Department of Microsystems Engineering (IMTEK) at the University of Freiburg, is developing a new method for the controlled interrogation and recording of neuronal activity in the brain. To do this, the team is taking advantage of thin, cell-sized optical fibers for minimally invasive optogenetic implantation. “We combine side-emitting fibers with silicon probes to achieve high-quality recordings and ultrafast, multichannel optogenetic control.”

They call the system Fused Fiber Light Emission and eXtracellular Recording, or FFLEXR. In addition to optical fibers that can be attached to any silicon probe, the team uses linear depth-resolved stimulation, a lightweight fiber matrix connector, a flexible multifiber ribbon cable, an optical commutator for efficient multichannel stimulation, a general-purpose patch cable, and an algorithm to manage the photovoltaic response.

A large new study shows people who contracted #COVID19 faced substantially higher risks of neuropsychiatric ailments 1 year later, including brain fog, depression, and substance use disorders.

Dozens of papers have examined the lingering mental health effects of COVID-19, but many have measured conditions such as depression and brain fog only a few months after infection. Now, a giant new study shows people who contracted COVID-19 faced substantially higher risks of neuropsychiatric ailments 1 year later, including brain fog, depression, and substance use disorders. The report, based on millions of people who used the U.S. Department of Veterans Affairs (VA) health system early in the pandemic, is published today in.

“Most of us experienced some sort of mental distress during the pandemic, but this shows that people with COVID-19 had a much higher risk of mental health disorders than their contemporaries,” says senior author Ziyad Al-Aly, a clinical epidemiologist at Washington University in St. Louis and chief of research at the VA St. Louis Health Care system. “It’s a wake-up call.”

TAMPA, Fla. (WFLA) — Following multiple news organizations covering allegations of animal abuse at Neuralink, Elon Musk’s brain chip company, the tech developer issued a statement on its animal welfare policies.

Earlier this month, the Physicians Committee for Responsible Medicine announced lawsuits against the University of California, Davis and Neuralink over its treatment of the macaque monkeys used to test the experimental brain implants developed by Musk’s company.

Ability of immune system to destroy Alzheimer’s-related protein oscillates with daily circadian rhythm.

The brain’s ability to clear a protein closely linked to Alzheimer’s disease is tied to our circadian cycle, according to research published recently in PLOS Genetics. The research underscores the importance of healthy sleep habits in preventing the protein Amyloid-Beta 42 (AB42) from forming clumps in the brain, and opens a path to potential Alzheimer’s therapies.

“Circadian regulation of immune cells plays a role in the intricate relationship between the circadian clock and Alzheimer’s disease,” said Jennifer Hurley, an expert in circadian rhythms, and associate professor of biological science at Rensselaer Polytechnic Institute. “This tells us a healthy sleep pattern might be important to alleviate some of the symptoms in Alzheimer’s disease, and this beneficial effect might be imparted by an immune cell type called macrophages/microglia.”

Ion channels are crucial for neural communication; they control the flow and gradient of charged particles, creating electrical signals. Recent work report | Neuroscience.

In this study, the researchers assessed how dense ion channels were packed in the membranes of neuronal cells from ten species of mammals, including mice, rats, rabbits, ferrets, macaques, marmosets, macaques, humans, and one of the smallest known mammals, an animal called the Etruscan shrew. The team focused on a type of excitatory neuron typically found in the cortex of the brain, and three ion channels that are in the membranes of those cells; two are voltage-gated ion channels that control the movement of potassium, another is called the HCN channel and both potassium and sodium ions can flow through it.
