Neural Network

In a new survey, 76% of scientists said that scaling large language models was "unlikely" or "very unlikely" to achieve AGI.

The first-ever "biological computer" powered by human cells, which form an ever-learning neural network, has been launched. It's an entirely new kind of AI – Synthethic Biological Intelligence – and not even its creators can predict its full potential.

Interests can modulate language processing in children's brains, according to a new MIT study. The approach paves the way for personalized brain research.

We're told that they give us a mental workout, but the evidence suggests it's a bit more complicated …

MIT researchers have found surprising patterns of dopamine signaling that suggest neuroscientists may need to refine their model of how reinforcement learning occurs in the brain.

Rats will choose to take a longer route if it means they get to enjoy the ride to their destination.

By digitally mapping the whole brain of a fruit fly, scientists hope to gain insight into human brain disorders

A better understanding of the process could lead to better pain treatments.

This week's reading is a mix of innovation, brainy body connections, and a dash of debunking. Apple engineers are turning AirPods into hearing aids—why stop at music when you can reinvent healthcare? Meanwhile, the vagus nerve is doing its mysterious thing, linking brain and body. And it turns out, that in the Blue Zones, living forever might just be creative bookkeeping.

Researchers at Cornell University tapped into fungal mycelia to power a pair of proof-of-concept robots. Mycelia, the underground fungal network that can...

Precision psychiatry is replacing the one-size-fits-all, trial-and-error approach with objective, biologic measures to determine optimal, individualized treatments.

The "Transformational Strategies in Mental Health" 2024 Spring Symposium at MIT stressed interdisciplinary collaboration and emerging technologies in advancing understandings of mental health and neurological conditions.

Harvard scientists developed a virtual rat model with an AI brain to study how brains control the movement of real rats.

MIT researchers developed a way to perform deep brain stimulation using ultrasound waves instead of electricity. The approach may offer a safer way to deliver deep brain stimulation, and could be a valuable tool for researchers seeking to learn more about how the brain works.

Scientists harnessed a new method to precisely measure the amount of information the brain can store, and it could help advance our understanding of learning.

When some people with autism spectrum disorders experience an infection that sparks a fever, their autism-related symptoms seem to improve. A joint MIT Picower Institute/Harvard Medical School study will investigate the "fever effect" in an effort to devise therapies that mimic its beneficial effects.

MIT associate professor Mark Harnett studies the electrical properties of neurons and how they enable neural circuits to perform the computations that give rise to brain functions such as learning, memory, and sensory perception.

Spinal circuits are central to movement adaptation, yet the mechanisms within the spinal cord responsible for acquiring and retaining behavior upon experience remain unclear. Using a simple conditioning paradigm, we found that dorsal inhibitory neurons ...

News and commentary from the world of neurology and neuroscience

Artificial intelligence (AI) has the potential to transform technologies as diverse as solar panels, in-body medical sensors and self-driving vehicles. But these applications are already pushing today's computers to their limits when it comes to speed, memory size and energy use.
