Brain-machine interfaces may be used to study and regulate mood

Brain-machine interfaces translate brain signals into information that can be used to control robotic limbs, and now even predict an individual’s mood state. Researchers envision using BMIs together with electrical stimulation, to regulate abnormal brain signals in patients with treatment-resistant neuropsychiatric disorders. Continue reading Brain-machine interfaces may be used to study and regulate mood

Pigs & Immortality: A Step Towards Reversing Death

Researchers from the Yale School of Medicine have developed a system capable of sustaining certain aspects of brain function for several hours, even if the host animal has been dead for up to four hours beforehand. While this by no means suggests that complete restoration of neurological function is on the horizon, it reveals the surprising resilience of post-mortem brain tissue, introduces a promising technique that could allow scientists to study certain biological functions outside of live animals, and highlights the important ethical considerations that must be discussed before any potential complete resuscitation of neurological activity is achieved.

Read My Mind: An Implant That Translates Brain Activity into Speech

For those who lose or lack the ability to speak, communication can be slow and painstaking. For example, towards the end of his life famed cosmologist Stephen Hawking communicated solely through the movement of a single cheek muscle as a result of his motor neuron disease (ASL). With the aim of finding a solution to this problem, a team at University of California have coupled … Continue reading Read My Mind: An Implant That Translates Brain Activity into Speech

Need to jog your memory? A zap to the brain could help

As you read this article, you may not be consciously trying to memorize each sentence, but the words do need to stick around temporarily. After all, you have to remember what you just read to understand the full article. This is your working memory, sometimes called “short-term memory,” and it allows us to remember things just long enough to complete a task. Its decline is … Continue reading Need to jog your memory? A zap to the brain could help

No, It’s Not Just You: Why time “speeds up” as we get older

How a clock measures time and how you perceive it are quite different. As we grow older, it can often feel like time goes by faster and faster. This speeding up of subjective time with age is well documented by psychologists, but there is no consensus on the cause. In a paper published this month, Professor Adrian Bejan presents an argument based on the physics … Continue reading No, It’s Not Just You: Why time “speeds up” as we get older

Scientists control rat’s movements with their minds

The concept of mind control sounds like something that only exists in sci-fi movies. Until now. Recent work from Zhejiang University on developing a system appears to allow human mind control over the rat’s movements. This “brain-to-brain interface”, or BBI, is achieved by wirelessly coupling the brains of a human operator and a “rat cyborg” and transmitting brain activity in real time. Brain cells communicate … Continue reading Scientists control rat’s movements with their minds

Double Vision: A Second Visual Pathway in Mice

A study of the mouse brain found that a region involved in processing visual motion does not depend on the area thought to be the primary source of visual information, but rather a separate structure. While a similar discovery in the analogous region of primates has yet to be made, this suggests the presence of non-conventional pathways in sensory processing and highlights that, even in widely studied areas, there is still much to learn. Continue reading Double Vision: A Second Visual Pathway in Mice

‘Pacemaker for the brain’ may help prevent seizures and treat movement disorders

Anyone who has ever been scolded for talking over someone knows that speaking and listening simultaneously is a hard thing to do. Conducting an intelligent conversation requires active listening, understanding the received knowledge, and crafting a meaningful response, which often requires blending the new information with one’s own experiences. On a microscopic scale, each neuron in the brain must do exactly this – listen to … Continue reading ‘Pacemaker for the brain’ may help prevent seizures and treat movement disorders
