... poorly understood. All of this is beginning to change. This Review provides a comparative perspective on mechanisms of wound healing and regeneration, with a focus on lizards as an emerging model. Not only are lizards able to regrow cartilage and the spinal cord following tail loss, some species can also...

...Ian T. Gordon; Patrick J. Whelan SUMMARY Networks within our spinal cord generate the basic pattern underlying walking. Over the past decade, much progress has been made in our understanding of their function in a variety of vertebrate species. A significant hurdle has been the identification...

...Milka Radmilovich; Anabel Fernández; Omar Trujillo-Cenóz SUMMARY The spinal cords and brains - comprising dorsal cortex (DC), medial cortex(MC) and diencephalon (Dien) - of juvenile turtles acclimated to warm temperature [27-30°C; warm-acclimated turtles (WATs)] revealed higher density values...

...Richard B. Borgens; Riyi Shi; Debra Bohnert SUMMARY Topical application of the hydrophilic polymer polyethylene glycol (PEG) to isolated adult guinea pig spinal cord injuries has been shown to lead to the recovery of both the anatomical integrity of the tissue and the conduction of nerve impulses...

...Li Guan; Tim Kiemel; Avis H. Cohen SUMMARY A semi-reduced, minimally restrained lamprey preparation was used to investigate the impact of movement and movement-related feedback during d -glutamate-induced locomotion. The preparation consisted of the trunk alone with the spinal cord exposed...

... with the observed body temperature displacements and our knowledge of regional cold sensitivity. When T a was lowered from 28 to −10 °C, the threefold increase in MR was accompanied by a significant increase in deep-body and spinal cord temperatures. Cold exposure also resulted in a distinct rise in breast skin...

...Nelson L. Daló; John C. Hackman; Kenneth Storey; Robert A. Davidoff ABSTRACT The effects of sudden cooling of the spinal cord were studied in three species of amphibians – a cold-sensitive tropical toad ( Bufo marinus ), a cold-resistant, aquatic, hibernating frog ( Rana pipiens , northern leopard...

...S. K. A. Woodward; J. M. Treherne; G. W. Knott; J. Fernandez; Z. M. Varga; J. G. Nicholls ABSTRACT The ability of neurites to grow through a lesion and form synaptic connections has been analyzed in a developing mammalian spinal cord in vitro . After isolation of the entire central nervous system...

...Jan E. Østnes; Claus Bech ABSTRACT In the present study we compared the metabolic responses to selective cooling of the cervical (C 9 –Th 1 ) and the thoracic (Th 1 –Th 5 ) parts of the spinal cord of pigeons. To obtain selective cooling of the two parts, two thermodes (4.5 cm) were inserted...

...S. R. Soffe; K. T. Sillar ABSTRACT Intracellular recordings have been made from ventrally located neurones in the spinal cord of Rana temporaria embryos at around the time of hatching. Both short-latency ‘reflex’ and more prolonged rhythmic motor responses can be elicited by stimulation of the skin...

...T. M. Jessell; K. Yoshioka; C. E. Jahr ABSTRACT Intracellular recording techniques have been used to provide information on the identity of excitatory transmitters released at synapses formed between dorsal root ganglion (DRG) and spinal cord neurones in two in vitro preparations. Explants...

..., a primitive vertebrate, can be produced in the isolated spinal cord in vitro ( Cohen & Wallén, 1980 ; Wallén & Williams, 1984 ). The capacity to generate the rhythmic pattern is distributed throughout the spinal cord, and short pieces of just a few segments may produce a coordinated pattern ( Cohen...
