A step has been taken toward the possibility of tuning the strength of memory by manipulating one of the brain's signaling memory mechanisms, a neurotransmitter called acetylcholine.
A team of researchers has recorded the brain activity of 50 people wearing an electroencephalogram headset while they looked at a series of 500 images. They found that participants' brains reacted differently to each image, enough that a computer system was able to identify each volunteer's 'brainprint' with 100 percent accuracy.
EPFL scientists propose a new way of understanding of how the brain processes unconscious information into our consciousness. According to the model, consciousness arises only in time intervals of up to 400 milliseconds, with gaps of unconsciousness in between.
Scientists harnessed a man’s brain waves to help him move his paralyzed hand again.
Bionic convergence and psychic uploading won’t be possible unless we crack the neural code, science’s hardest problem.
Researchers seeking to unlock the secrets of how the brain works have created the largest and most detailed map of connections between brain cells ever produced.
Our neurons are derived from progenitor cells, which are specialized stem cells that have the ability to divide to give rise to neurons. Today, neuroscientists shed light on the mechanisms that allow progenitors to generate neurons.
It’s a case of life imitating art. Much as the sci-fi film “The Matrix” depicted a device capable of enhancing skill acquisition, researchers at HRL Laboratories, LLC, have discovered that low-current electrical brain stimulation can modulate the learning of complex real-world skills.
A dial-like structure found on brain cells called astrocytes means they are "actually incredibly flexible and potentially modifiable," says Keith Murai.
Researchers at Johns Hopkins Bloomberg School of Public Health have produced tiny brains made of human neurons and cells. These mini-brains could radically change how drugs are tested, replacing the many animals currently being used for neurological scientific research.
DARPA wants to develop a tiny device that would translate the electrochemical language of the brain into the 1s and 0s of computers.
The brain's memory capacity is in the petabyte range, as much as entire Web, new research indicates. The new work answers a longstanding question as to how the brain is so energy efficient and could help engineers build computers that are incredibly powerful but also conserve energy.
Our brains are arguably one of evolution's greatest achievements, composed of many regions that each have unique configurations of cells and patterns of connectivity that together bestow us our mental prowess. But what is it about our genes that makes this organ so distinct from those of others?
Researchers at the University of Wisconsin, Madison, led by Minrui Yu, have successfully induced nerve cell tendrils to grow through semiconductor tubes
Northwestern University scientists have discovered that axons can operate in reverse: they can also send signals to the neuron cell body, too. Previously, it
