Explants of fetal mouse cerebral cortex, continuously exposed to the local anesthetic Xylocaine from the time of explantation to the time of fixation, were examined in the electron microscope to determine whether morphologically normal synapses and p

Afferents often form synapses on restricted regions of their target cells. The connections between vestibular axons and the Mauthner cell are an example of this sort of specificity. The Mauthner cells are a pair of identifiable central neurons in cer

Vestibular axons form synapses on a restricted area of the lateral dendrite of the Mauthner cell, a large, identified brainstem neuron found in fish land amphibians. The differentiation of the vestibular nerve, medullary neuropil, and Mauthner cell o

In the developing amphibian, the formation of extra vestibular contacts on the Mauthner cell (M-cell) enhances dendritic branching, while deprivation reduces it (Goodman and Model, 1988a). The mechanism underlying the interaction between afferent fib

SYNOPSIS. In premetamorphic amphibians, the Mauthner cells (M-cells), a single pair of large neurons, are present in the medulla. M-cells differentiate early, are easily recognized morphologically, and in the axolotl embryo, may be approached experim

In the amphibian embryo, beginning in the late neurula and continuing through midtailbud stages, the developing medulla exerts an inductive influence on the prospective ear, effecting its determination. Fine structural analysis of the region of close

In early tailbud embryos of the axolotl ( Ambystoma mexicanum ), cells of the anterior myotomes begin to elongate and align along the longitudinal axis of the animal. Soon thereafter, gap junctions appear between the differentiating myotubes. These j

To see whether phenylalanine serves as a substrate in melanogenesis, hanging drop explants of neural crest from amphibian (Ambystoma maculatum and A. mexicanum) embryos were subjected on the seventh day in vitro to treatment with phenylalanine-3H and

Migration of trunk neural crest cells in axolotl embryos has been followed by autoradiography using grafts of [3H]thymidine-labeled neural folds. Crest cells form melanocytes, dorsal fin mesenchymal cells, spinal ganglion cells, and reach the sympath
