DISCLAIMER: Although we sometimes compare certain symptoms in zombies to real neurological patient populations, we are in no way implying that patients with these other disorders are in some way “part zombie”. Neurological disorders have provided critical insights into how the brain gives rise to behavior and we bring them up for the sake of illustration only. Their reference in this context is in no way meant to diminish the devastating impact that neurological diseases can have on patients and their caregivers.In order to understand how studies on patients, brain regions, and behavior all link together, check out BrainScanr ( http://www.brainscanr.com/ ), a meta-analytic program designed to show relationships between brain systems and behavior.For more information on the syndromes described in the video, including how to help, please check out the following support societies:Parkinson’s Disease Foundation: http://www.pdf.org/ The National Ataxia Foundation: http://ataxia.org/ The National Aphasia Foundation: http://www.aphasia.org/ To learn more about the basal ganglia, cerebellum, and language networks, please check out the following open-access reviews:Schwartz MF, Dell GS.
