A Woman Without Her Left Temporal Lobe Developed An Intricate Right-Brain Language Network That Did Not Impede Communication

The team of researchers was intrigued by EG’s uninhibited abilities and decided to use an fMRI machine to capture images of her brain during different activities.

EG practiced things like math and language processing so the researchers could understand her neuropathways.

In doing so, the team found that no language processing occurred in the left side of her brain. Instead, all of the processing happened on the right side.

The researchers believe the woman likely suffered from a stroke or related injury as a child, which caused her to lose her left temporal lobe. Cerebrospinal fluid had filled the region and forced her brain to compensate.

In turn, EG had developed a unique language network on her brain’s right side that allowed her communication to flourish.

Additionally, EG has a twin sister who does not have a right temporal lobe. She, too, displays no abnormal behavior or speech impediments.

So, the researchers believe that a genetic variable went hand in hand with the stroke and miraculous recovery of the twins.
