Electronic chip, interacting with the brain, modifies pathways for controlling movement

ochip records the activity of motor cortex cells," Fetz explained, "It can convert this activity into a stimulus that can be sent back to the brain, spinal cord, or muscle, and thereby set up an artificial connection that operates continuously during normal behavior. This recurrent brain-computer interface creates an artificial motor pathway that the brain may learn to use to compensate for impaired pathways."

Jackson found that, when the brain-computer interface continuously connects neighboring sites in the motor cortex, it produces long-lasting changes. Namely, the movements evoked from the recording site changed to resemble those evoked from the stimulation site.

The researchers said that a likely explanation for these changes is the strengthening of pathways within the cortex from the recording to the stimulation site. This strengthening may have been produced by the continuous synchronization of activity at the two sites, generated by the recurrent brain-computer interface.

Timing is critical for creating these connections, the researchers said. The conditioning effect occurs only if the delay between the recorded activity and the stimulation is brief enough. The changes are produced in a day of continuous conditioning with the recurrent brain-computer interface, but last for many days after the circuit is turned off.

"This unusually long-lasting plasticity may be related to the fact that the conditioning is associated with normal behavior," Fetz said.
