A decoder
translates these neural signals into commands that move computer cursors and prosthetic limbs.
But Kennedy collaborator Frank Guenther, associate professor of cognitive and neural systems at Boston University, and his colleague Jonathan Brumberg recently worked out a system that
translates neural signals from Ramsey's implant into vocal form via a synthesiser that produces the corresponding sound.
As for those patients whose brains are trapped in inanimate bodies, implants that pick up electrical impulses can already
translate neural signals to control a cursor, move a wheelchair, or say hello, although they are not now suitable for people with severe brain injuries.
Not exact matches
By matching her intended movements with their corresponding
neural signals, the researchers were able to write a computer code that
translated her thoughts into directions for the robotic arm.
A tiny sensor implanted in Nagle's motor cortex reads
neural signals associated with arm movement, transmitting them via fiber - optic cable to processors that
translate thoughts into actions.
Resulting
neural signals from the motor cortex were electronically extracted by the embedded recording devices, transmitted to a computer and
translated by Shenoy's algorithms into commands directing a cursor on an onscreen keyboard to participant - specified characters.
The
neural signals recorded by the electrodes are transmitted via a cable to a computer where algorithms developed in Shenoy's lab decode the participant's intentions and
translate the
signals into movements of a computer cursor.
The
signals can be localized in the brain and
translated into digital images that portray
neural activity level as a ratio of oxygenated to de-oxygenated hemoglobin, the iron - containing pigment in red blood cells.
The scientific community has learned a great deal about molecular
signals that can support regeneration of damaged
neural connections, but there is an urgent need to identify as many pro-regenerative
signals as possible because it is not clear which of these might actually
translate to use in patients.
