Researchers have pinpointed the brain area that
controls our ability to correct our movement after we have been hit or
bumped.
The fact that humans rapidly correct for any
disturbance in motion shows the brain understands the physics of the
limb.
“To say this process is complex is an
understatement,” said Stephen Scott, neuroscience professor and motor
behaviour specialist at the Queen’s University.
“Voluntary
movement is really, really hard in terms of the math involved. The best
physicists cannot solve these complicated equations, but your brain can
do it incredibly quickly,” he added.
For example, a
soccer player who collides with an opponent during a game has to respond
quickly to correct the movement and remain upright, according to a
university statement.
Strokes that take place in the
primary motor cortex may cause varying levels of damage to this
corrective movement pathway.
This varying damage may
explain why some stroke patients are able to improve their movement
skills in rehabilitation and why some patients remain uncoordinated and
unsteady.
