Why the left hemisphere of the brain understands language better than the right

(Ruhr-University Bochum) Nerve cells in the brain region planum temporale have more synapses in the left hemisphere than in the right hemisphere -- which is vital for rapid processing of auditory speech, according to the report published by researchers from Ruhr-Universit ä t Bochum and Technische Universit ä t Dresden in the journal Science Advances. There has already been ample evidence of left hemisphere language dominance; however, the underlying processes on the neuroanatomical level had not yet been fully understood.
