Advances in Brain Implants Enable Reading and Listening to Inner Thoughts

A study published in Cell reveals that brain implants can decode not only attempted speech but also imagined inner speech, raising privacy concerns about mental privacy as technology advances. Researchers found that AI can translate faint brain signals associated with inner speech into words, which could make communication easier for paralyzed individuals but also pose risks of unintentional mind-reading. Protective measures like wake words were tested, but experts warn that the boundary between private and public thoughts may become blurred, especially with future consumer devices.

"The Unusual 'Signal' Humans Emit Before Telling a Lie, Unveiled by Scientists"

Scientists from the University of Pennsylvania and the University of Chicago have discovered that the hippocampus, a part of the brain involved in memory, sends a distinct electrical signal before a false memory or unintended lie is told. By studying the electrical activity in the hippocampus of epilepsy patients, the researchers found that the rhythm changed when subjects recalled a list of words correctly or incorrectly, indicating the ability of the hippocampus to distinguish between true and false memories. This research could contribute to understanding how the brain retrieves memories, particularly in cases of distress-related conditions like post-traumatic stress disorder.

Unveiling the Surprising Similarities in Decision-Making Between Insects and Mammals

Insects, contrary to previous beliefs, can make complex decisions based on experiences rather than just reacting to stimuli. The mushroom body in arthropod brains, responsible for memory formation and decision-making, encodes behavioral decisions during sensory-motor transformation. The study, conducted on American cockroaches, showed that the output neurons of the mushroom body take into account the animal's current state, such as hunger, enabling precise prediction of behavior. This research has implications for understanding not only insect behavior but also basic neurobiological principles that are similar in humans.

Scientists Use Brain Scans to Recreate Pink Floyd Song

Researchers at the University of California at Berkeley have used brain scans and AI to recreate a Pink Floyd song, "Another Brick in the Wall, Part 1," from neural signals. By recording the brain activity of 29 patients who listened to the song, the scientists decoded the data and reconstructed it into audio. This breakthrough could potentially help patients with speech impediments communicate and provide insights into how the brain processes sound and music. The study also opens up possibilities for composing music through thought and developing medical applications for decoding words patients want to say.
