A study published today in the prestigious journal Nature by Dr. Michael Petrides and colleagues at the Montreal Neurological Institute (MNI) at McGill University, challenges current thinking that speech developed as a result of new structures that evolved in the human brain. Dr. Petrides and colleagues have identified a distinct brain region that controls jaw movements in macaque monkeys that is comparable to Broca’s area - the region in the human brain critical for speech production. This discovery is important as it suggests that this area of the brain evolved originally to perform high-order control over the mouth and the jaw, and that as humans evolved this area came to control the movements necessary for speech.
“Our study shows that nonlinguistic monkeys possess an area comparable to Broca’s area – it is located in the same region and has the same anatomical characteristics as Broca’s area in the human brain“, explained Dr. Michael Petrides, Coordinator of the Cognitive Neuroscience Unit at the MNI and Professor in the Department of Neurology and Neurosurgery, McGill University.
"The researchers performed quantitative microscopic analysis of the cytoarchitecture of the region of interest and electrophysiological stimulation and recording within this region.

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
