Italian Researchers Identifies Gesture Recognition Sites in Brain - Stroke Victims Benefitted
Italian researchers have brought fresh hope to stroke victims by identifying the part of the brain responsible for assessing actions and gestures.
Up till now, it was impossible to do this because stroke victims, who are usually impeded in their speech or other abilities to communicate, were unable to give feedback to researchers.
The breakthrough was made possible by ‘tricking’ the brains of healthy individuals to behave like those of stroke victims, without disturbing their capacity to communicate .
A team at the International School of Advanced Studies in Trieste used Transcranial Magnetic Stimulation (TMS) to pinpoint the frontal cortex as the part of the brain that interprets other people’s actions .
Researchers sent TMS current through various points while the person was asked to watch a film of someone picking up a box, and guess its heaviness.
In the end, it was discovered that estimates were wildly inaccurate when TMS was delivered to the frontal cortex.
Researchers led by Serbian-born Gorana Pobric say this will pave the way for significant advances in rehabilitation techniques for stroke victims.
