World-renowned brain cartographer Scientia Professor George Paxinos AO from Neuroscience Research Australia (NeuRA) has recently discovered a previously unknown hidden part of the brain. He found the region close to the brain-spinal cord junction.

Scientists have named this region the Endorestiform Nucleus. This discovery is expected to help scientists explore cures for diseases, including Parkinson’s and motor neuron disease.

Professor Paxinos identified the region almost 30 years ago, but due to the lack of better techniques, he was unable to make it clear. Now, using better staining and imaging techniques, he found that the Endorestiform Nucleus is located within the inferior cerebellar peduncle. The Inferior cerebellar peduncle integrates sensory and motor information to refine posture, balance, and fine motor movements.

Professor Paxinos said, “The region is intriguing because it seems to be absent in the rhesus monkey and other animals that we have studied. This region could be what makes humans unique besides our larger brain size.”

“I can only guess as to its function, but given the part of the brain where it has been found, it might be involved in fine motor control.”

Professor Peter Schofield, CEO at NeuRA, said, “Professor Paxinos’ atlases showing detailed morphology and connections of the human brain and spinal cord, provide a critical framework for researchers to test hypotheses from synaptic function to treatments for diseases of the brain.”

Natalie Farra, Senior Editor at Elsevier, said, “It is truly an honor for Elsevier to continue Professor Paxinos’ legacy of publishing with us. His books are world-renowned for their expertise and utility for brain mapping and for their contributions to our understanding of the structure, function, and development of the brain.”

The discovery of the Endorestiform Nucleus is detailed in Professor Paxino’s latest book titled Human Brainstem: Cytoarchitecture, Chemoarchitecture, Myeloarchitecture, available for order this November 2018.
