A lot of us take our fingertips apart and see if we can see them on the screen.
But what about our hands?
When do our hands get so tired that they become unusable?
And what about when we have no fingers?
These are the questions being asked by researchers at the University of Sydney, the University Of Manchester and the University in Oslo.
Their findings suggest that fingers and hands might be able to take on a lot more than the standard tests.
The research, published in the journal Frontiers in Human Neuroscience, found that while the tests were easy to administer and performed well, the finger-based tests were too slow to test for the brain’s electrical activity.
For the study, researchers used electrodes placed on the top of two fingers and an electrode on the underside of one finger.
They tested each finger on a range of tasks to determine the accuracy of the testing.
Using the electrodes, the researchers were able to see how the two fingers would move when moving a virtual finger around a computer screen.
They found that the average finger-driven speed was 1.3 millimetres per second, and that the accuracy was even better when the two tests were done simultaneously.
But what about the brain?
This time, the scientists looked at a different part of the brain.
When people are testing their fingers, they typically use a special device called a finger motor.
This allows the fingers to move as if they were connected to an electronic device.
This is known as a computer-aided test (CAT) because the fingers are connected to a special type of electrical circuit called a touch-screen monitor.
When the researchers performed the finger motor test, the participants performed much better, on average, with a finger-generated speed of 1.6 millimetre per second.
However, the tests weren’t as accurate with a computer.
They performed about 50 per cent worse than the computer, which means the brain could only perform about 10 per cent of the task.
The researchers were surprised to find that the brain was actually performing much worse with the computer than it was with the finger, which was about one-third the accuracy.
This means that, when tested with a mouse and a keyboard, the brain is not able to produce the same accuracy.
“This is a very significant finding,” said lead author Dr Helen Dickson, from the University’s School of Biological and Computer Sciences.
“For a person with poor dexterity, their hands may be able for a time to perform tasks without using their fingers at all.”
She said this could be particularly concerning for people with dementia, who may have difficulty with their fingers and are less likely to have their brains tested.
“There are lots of conditions that affect your hand, such as repetitive strain injuries or repetitive strain injury,” Dr Dickson said.
“It may be a lot harder for the finger to do the work of the hand and it may not even be possible to control the finger.”
We’ve had some of these tests done in humans with the symptoms of dementia.
“Dr Dickson and her team are currently testing ways to improve these finger-controlled tests, and hopes to use these to find ways to speed up other tests.
