Flexibility of the axial central pattern generator network for locomotion in the salamander.
In tetrapods, limb and axial movements are coordinated during locomotion. It is well established that inter- and intralimb coordination show considerable variations during ongoing locomotion. Much less is known about the flexibility of the axial musculoskeletal system during locomotion and the neural mechanisms involved. Here we examined this issue in the salamander Pleurodeles waltlii, which i...
متن کاملThe mammalian central pattern generator for locomotion.
At the beginning of the 20th century, Thomas Graham Brown conducted experiments that after a long hiatus changed views on the neural control of locomotion. His seminal work supported by subsequent evidence generated largely from the 1960s onwards showed that across species walking, flying, and swimming are controlled largely by a neuronal network that has been referred to as the central pattern...
متن کاملOrganisation of the spinal central pattern generators for locomotion in the salamander: biology and modelling.
Among living tetrapods, salamanders are regarded as most closely resembling the first terrestrial vertebrates, and are therefore an interesting group in which the evolutionary changes in the locomotor behaviour from aquatic to terrestrial habitats can be inferred. Salamanders exhibit two locomotor modes: swimming and terrestrial stepping. The swimming is anguilliform and resembles closely that ...
متن کاملSerotonin modulates the central pattern generator for locomotion in the isolated lamprey spinal cord.
The central pattern generator for locomotion in the spinal cord of the lamprey can be activated in vitro by the addition of D-glutamate to the bathing saline. Serotonin has no effects when bath-applied alone, but it modulates the D-glutamate-activated swimming pattern. Three major effects are observed: a dose-dependent reduction in the frequency of rhythmic ventral root burst discharge; enhance...
