Brain implant lets man with paralysis move and feel with his hand

A brain implant has restored movement and a sense of touch in the hand of a man with a severe spinal cord injury.

Patrick Ganzer at Battelle Memorial Institute in the US and his colleagues have developed a brain-computer interface (BCI) that     1     (allow) 28-year-old Ian Burkhart to grasp and feel objects again.

Burkhart has a severe upper spinal cord injury and has complete paralysis in his hands and legs,     2     can move his elbows and shoulders. He had a brain implant inserted in 2014 as part of research aiming to restore movement in     3     right arm.

The BCI uses the implant     4     (record) brain activity that is sent to a processor that decodes these signals into movements, which in turn feed in to bands around the forearm which electrically activate his hand muscles.

“We’ve made a lot of progress in the last six years: he can play [the video game] Guitar Hero, swipe a credit card and do about 20 different hand grips,” says Ganzer.

But because Burkhart had no sensation in his hands, he previously had no sense of touch or pressure when     5     (grasp) objects, and if blindfolded, was not able to detect small objects such as a pencil.

The researchers discovered that     6     Burkhart’s hand cannot feel anything, the brain implant stills registers a faint sensory signal when he touches an object.

They boosted this signal by incorporating a band around the bicep which vibrates when Burkhart’s hand receives sensory information.

As a result, Burkhart is able to detect objects by touch alone. The BCI is also able to detect different levels of touch and adjust the strength of Burkhart’s hand movements depending on the object – a light grasp, for example, for a paper cup.

The researchers believe it is the first BCI     7     can simultaneously restore movement and touch.

When the brain implant was inserted, it     8     (intend) solely for controlling movement, but the     9     (add) touch is possible because there is some overlap     10     the sensory and motor areas in Burkhart’s brain, says Ganzer.

Water doesn't currently exist on Mars' surface, but it used to. About 4 billion years ago, something happened to Mars' atmosphere, and most of the liquid water     1    （disappear） due to harmful radiation. But some of     2     may still be underground. Could those ancient water holes contain life?

China's Tianwen-1 mission will search     3    the existing water by radar fixed on the rover （月球车）.The European Space Agency's spacecraft found evidence for subsurface water,     4    （use） radar from space, but this will be the first time a rover has searched from the ground.

Tianwen-1 will also give China     5    （value） Mars experience and lay foundation for a sample return mission planned for     6    end of the 2020s. Getting Martian samples back to Earth is a top priority for the scientific community. Despite the impressive advances     7    （make） in placing science instruments on spacecraft, only the technology on Earth,     8    can test samples accurately, is to verify the presence or absence of life in a sample.

As of 2020, only NASA has landed and operated spacecraft on Mars     9    （successful）. More countries exploring Mars means more     10    （opportunity） for global cooperation. Space exploration brings out the best in us all. When more nations work together, everyone wins.
