The experimental system, developed and tested in just one patient so far, relies on brain signals associated with handwriting to achieve the fastest communication yet seen with BCI.

The California-based company Humm has developed a “bioelectric memory patch” to improve working memory, but some experts question the efficacy of the device.

The surprising finding comes courtesy of two study participants with implanted electrode arrays that record activity at single-neuron resolution.

Slowing to just two beats per minute, the animals’ heart rate shows how they survive plunging far below the ocean’s surface to eat.

A newly developed device can better measure brain waves such as those used to control a robotic car.

A proof-of-principle study raises hopes that technology can give a voice to paralyzed people unable to speak.

Researchers record neurological changes in a region called the mushroom body in the brains of bees completing a maze in a virtual environment.

A perception of sustained focus may actually be the result of cycles of fluctuating rather than continuous neural activity, according to new behavioral and neurological data from studies in humans and macaques.

Software that can separate signals from noise brings neuroscientists a step closer to understanding neurons’ patterns of communication.

In people with epilepsy, transcranial alternating current stimulation (tACS) does not affect memory-related brainwaves as widely claimed, researchers report.

Micrometer-size magnetrodes detect activity-generated magnetic fields within living brains.

Newly designed sensors detect the magnetic fields generated by electrical activity within cat brains.

Current can guide implanted cells away from rats’ noses toward a region deep in their brains.

Two chips implanted in a quadriplegic patient’s motor cortex and 36 electrodes in his right arm allow the man to control the movement of his right arm and hand.

Imaging and manipulating the brain has come a long way from electrodes and the patch clamp, though such traditional tools remain essential.

Activity in the anterior cingulate cortex corresponds with observing the behavior of others when their actions, or the subsequent outcomes, don’t match one’s expectation.

Flexible patches of silicone that stick to skin and conduct electricity could serve as the basis for a new, reusable electrode for medical applications.
