title: Human quadrupedalism is not an epiphenomenon caused by neurodevelopmental malformation and ataxia creator: Tan, Prof. Dr. Uner subject: Behavioral Neuroscience subject: Neurology subject: Neurophysiology subject: Neuropsychology description: Two cases with quadrupedal locomotion (QL) were presented. In both cases, cognitive and psychiatric functions were normal and, no neurological deļ¬cits were observed, except for a sequel paralysis of left leg in Case 2. It was suggested that human QL (1) should not be considered as an epiphenomenon caused by neurodevelopmental malformation and ataxia, but (2) may be considered as a re-emergence of the ancestral diagonal QL, and (3) it may spontaneously emerge in humans with entirely normal brains, by taking advantage of neural networks such as central pattern generators that have been preserved for about 400 million years. publisher: Frontiers contributor: Karaca, Dr. Sibel contributor: Tan, Prof. Dr. Meliha contributor: Tan , Prof. Dr. Uner date: 2012-10-25 type: Journal (Paginated) type: PeerReviewed format: application/pdf identifier: http://cogprints.org/8982/1/UTS%20IS%20NOT%20AN%20EPIPHENOMENON.pdf identifier: Tan, Prof. Dr. Uner (2012) Human quadrupedalism is not an epiphenomenon caused by neurodevelopmental malformation and ataxia.
