40 percent of MRI signals misinterpreted

Interpretation of numerous MRI data may be incorrect: blood flow is not a reliable indicator of brain activity.

If a Meta AI model can read a brain-wide signal, why wouldn't the brain?

If a Meta AI model can read a brain-wide signal, why wouldn’t the brain?

In 2023, Meta researchers were able to decode images in thoughts from the brain's magnetic fields. What if that's how the brain coordinates it's own global state?

neuroTUM builds interface to the brain

For the Cybathlon, the neuroTUM student club connects the human brain with a computer. This enables pilot Leon to solve tasks despite being paralysed.

ADHD linked to disrupted brain signals involved in focusing attention

Disrupted brain signals have previously been linked to ADHD in children, with the link now being found in young adults, improving researchers' understanding of the condition

Seeing through the eyes of a mouse by decoding its brain signals

Is it possible to fully reconstruct what someone sees based on brain signals alone? The answer is no, not yet. But EPFL researchers have made an important step in that direction by introducing a new algorithm for building artificial neural network models that capture brain dynamics with an impressive degree of accuracy.
