Effects of neonatal splitting of the optic chiasm on the development of feline visual callosal connections.

abstract：:We examined the characteristic features of galanin (GAL)-containing nerve afferents in the intermediolateral nucleus (IML) of the rat lumbosacral spinal cord (L6, S1), i.e., spinal parasympathetic nucleus, by immunocytochemistry at both light and electron microscopic levels. Firstly, the types of synapses formed by GA...

abstract：:In frogs, each lobe of the midbrain optic tectum receives two spatially aligned maps of binocular visual space, one through each eye. The map from the contralateral eye is the product of direct retinal input to the tectum, while that from the ipsilateral eye is mediated by a commissural system of connections that rela...
