abstract：:The firing patterns of alpha and gamma efferent fibres and of group I and group II afferent fibres innervating the gastrocnemius muscle were observed during spontaneous locomotor movements in the thalamic cat. Multi-unit discharges of each kind of fibre were obtained by electronic sorting of the action potentials from...

abstract：:Visual input has a profound effect on the development of binocular maps in the tectum of the frog Xenopus laevis. Input from the ipsilateral eye, which is relayed to the tectum via the opposite nucleus isthmi, is normally in register with the retinotectal map from the contralateral eye. However, if one eye is rotated ...
