A new technology that is able to translate our brain signals into speech has been developed by a team of neuroscientists, neurosurgeons and engineers at Duke University in North Carolina. The device—known as a speech prosthetic—is significantly faster than the best speech-decoding technologies available…
Researchers have identified the genetic pathway between the heart and brain responsible for fainting, revealing a two-way communication that could lead to new treatments for syncope-related disorders. Neurobiologists have discovered sensory neurons that regulate fainting, providing a foundation for targeted treatments for related disorders….
( Nanowerk News ) For the first time, a physical neural network has successfully been shown to learn and remember ‘on the fly’, in a way inspired by and similar to how the brain’s neurons work. The result opens a pathway for developing efficient…

Some cases of OCD are notoriously difficult to treat. Responsive deep brain stimulation may help. Making sure a stovetop isn’t left on or readjusting an askew picture frame is often a natural response when something feels off. Yet, for over two million Americans living…
Amber Pearson has had a severe form of obsessive compulsive disorder since she was in high school. She would wash her hands so much they became raw and bled. Her bedtime routine easily took 45 minutes because it involved checking that all the doors…
The first-line pharmacological treatment for major depressive disorder (MDD) is antidepressant drugs known as selective serotonin reuptake inhibitors (SSRIs). However, a significant proportion of people don’t respond to these drugs. Given that major depression is a global mental health problem that is on the…
In a collaborative study led by the University of California San Diego, scientists have examined over 1 million human brain cells to craft intricate maps of gene regulators specific to different brain cell types. This research not only demonstrates the intricate links between distinct…
Recent developments in neuroscience and brain-inspired artificial intelligence have opened up new possibilities in understanding intelligence. Now, a research team led by Tianzi Jiang at the Institute of Automation of the Chinese Academy of Sciences has outlined the key components and properties of an…
Advertisement An autopsy report has confirmed that a Neuralink implant ruptured the brain of a female macaque during an experiment, forcing scientists to end its suffering. According to an Oct. 4 report by Wired magazine , the implant “deformed and ruptured” the brain of…

Researchers have identified a unique biomarker in the brain that signifies recovery from treatment-resistant depression, utilizing deep brain stimulation and artificial intelligence to understand and enhance treatment outcomes. A breakthrough study reveals a unique biomarker in the brain that tracks recovery from severe depression,…
Blue micrograph shows the activity of neurons in the hippocampus of a rat as shown by white flecks Neurons, the brain cells responsible for relaying chemical and electrical messages , have long been considered the key players in memory formation — but new research…

A new study clarifies past conflicting observations on visual recognition memory (VRM), showing that increased visual evoked potentials (VEPs) during the recognition of familiar stimuli signal the brain’s rapid identification process, ultimately leading to decreased overall neural activity. Since determining what we observe as…
A new lightweight device with a wisplike tether can record neural activity while mice jump, run and explore their environment. The open-source recording system, which its creators call ONIX, overcomes several of the limitations of previous systems and enables the rodents to move more…
A complete map of all the connections in an entire mammalian brain may be in sight. Allen Institute researchers have just launched three new projects to construct large, detailed maps of neuronal connections in sections of the mouse and macaque brains, with an eye…
Bengaluru: The US Food and Drug Administration (FDA) has given the green light to Neuralink, a company founded by Elon Musk, to conduct human trials in brain-computer interface (BCI) technology. This technology involves implanting a tiny chip in the brain that can read and…
