Homeostasis is the process by which the brain integrates the regulatory and restorative systems in the body to maintain health and adapt to environmental challenges. New visualization evidence from a magnetic resonance imaging (MRI) study of the human brain demonstrated previously unidentified structural connections between the brainstem and the forebrain.
Specifically, the investigators found neuroanatomic connections between the brainstem regions involved in autonomic and cardiorespiratory function and forebrain regions involved in homeostatic control. This research supports the concept that together these brain regions form an integrated central homeostatic network in the brain, as described in Brain Connectivity.
In 'The Structural Connectome of the Human Central Homeostatic Network', authors Brian Edlow, Jennifer McNab, Thomas Witzel, and Hannah Kinney, Harvard Medical School, Massachusetts General Hospital, Boston Children's Hospital (Boston, MA) and Stanford University (CA), present the results of MRI visualization in healthy adults to identify specific connections between six brainstem sites and seven forebrain regions that play a role in the critical function of homeostasis.
Christopher Pawela, Co-Editor-in-Chief of Brain Connectivity and Assistant Professor, Medical College of Wisconsin, said, "These investigators have detected neural anatomy previously undescribed in the literature using the MGH-USC Human Connectome MRI scanner. This study demonstrates the power of this unique instrument to unravel structural connections in brain regions that were previously difficult to image with conventional MRI scanners."
