✦ Synopsis

El papel del sistema nervioso en la regeneraci6n de 10s turbelarios policlhdidos.

Planocera californica, Phylloplana littoricola y Leptoplana saxicola siguen la regla en la regeneracih de 10s policlhdidos. Pueden restaurar partes perdidas siempre que 10s ganglios cefhlicos est6n intactes. Si estos ganglios se destruyen parcialmente o hieren no se produce nuevo tejido nervioso para restaurar el cerebro a su tamaiio original, y se se extirpan por completo la regeneraci6n no puede tener lugar anteriormente, aun cuando puede llevarse a cabo posteriormente. Si permanece en el animal una porci6n del cerebro, tiene lugar una cierta cantidad de regeneraci6n anterior y 10s ojos se regeneran, pero no se afiade bastante material para restaurar la forma original y 10s nuevos ojos nunca alcanzan el tamaiio de 10s presentes antes de la operaci6n.

## Abstract The aim of this study was to evaluate peripheral nerve regeneration across a 15‐mm gap in the sciatic nerve of the rat, using a silicone rubber nerve guide filled with different concentrations of astragaloside (0, 50, 100, and 200 μM). Collagen was also filled in the chambers to prevent

Cholinergic control of locomotory muscles in chaetognaths is monitored by diffuse transmitter release through layers of collagen fibers that form the connective stratum of the hydroskeleton. Despite the lack of morphologically defined synaptic junctions, the control of locomotor activity in chaetogn

## Abstract Reactive astrocytes are one of the main impediments for axonal regeneration in the central nervous system of mammals. Using mice KO for GFAP and vimentin, we show that reinnervation occurs after an hemisection of the spinal cord, mainly through sprouting of controlateral intact serotoni
