4) Active motor tasks are the most robust and established, although it is interesting to note that recent studies have also reliably identified motor regions
using passive tasks (5) and even at rest using functional connectivity fMRI.
There is, for instance, considerable evidence of invariant representations in the workings of the visual cortex, but it is not yet clear whether the concept applies broadly to other sensory areas and to motor regions
of the cortex.
A study suggests that those who began early had stronger connections between motor regions
- the parts of the brain that help you plan and carry out movements.
That is, individuals who scored higher in their ability to empathize with other people showed more activity in motor regions

Most of the motor regions
of the EU, Mexico, Singapore, Korea, Canada were there but only one company seemed to be flying the flag for Wales.
However, although some studies have suggested that while people are listening to speech, they silently articulate the words in order to understand them, the authors found no involvement of motor regions
when people were listening.
Itzhak Fried, a UCLA professor of neurosurgery and of psychiatry and biobehavioural sciences, Roy Mukamel, a postdoctoral fellow in Fried's lab, and their colleagues have recorded both single cells and multiple-cell activity, not only in motor regions
of the brain where mirror neurons were thought to exist but also in regions involved in vision and in memory.
So increased empathic ability is linked to the ability to perceive prosody as well as activity in these motor regions
, said authors Lisa Aziz-Zadeh and Tong Sheng of USC, and Anahita Gheytanchi of the Pacific Graduate School of Psychology.
Washington, Aug 19 (ANI): Researchers have found that the nerve fibres that link perception and motor regions
of the brain are disconnected in tone-deaf people.
