This study was made to identify the inhibitory interneurons belonging to the spinal circuitry activated by the Mauthner axons in the tench (Tinca tinca L.). The histological investigations were focused on a segmental pair of commissural interneurons

The effects of 4-aminopyridine (4-AP, 1 mg/kg i.v.) on the distribution of intramembranous particles in spinal motoneuronal synapses was examined in anesthetized (pentobarbital sodium, 50 mg/kg, i.p.) rats by freeze-etching electron microscopy. The p

Protoplasmic fracture faces of vesicle attachment sites (VSA) in the presynaptic active zone of rat spinal motoneurons were classified morphologically on the basis of particle-to-membrane relationships. Intramembranous particles are absent in type 1,

Impulse generation and propagation was previously shown to occur in skin epithelium of newt (Cynops orientalis) embryos during certain stages of development and to be correlated with morphological changes of gap junctions. These properties are not de

The distribution of membrane-associated particles in the presynaptic membrane was investigated in the spinal cord of unanesthetized and anesthetized rats by freeze etching electron microscopy. Both ‘external’ face (EF) and ‘protoplasmic’ face

In a light microscopic study the ferric ion-ferrocyanide staining of the squid giant axon was investigated. In other neurons this stain is known to indicate excitable membranes with high sodium channel density, such as the node of Ranvier or the init

Possible morphological correlates of dendritic release sites for dopamine have been investigated in the rat substantia nigra. Electronmicroscopic and freeze etching studies show that nigral dendrites fail to form dendrodendritic contacts but on the c

Summary The zinc iodide-osmium tetroxide (ZIO) stain of synaptic vesicles has been improved by combining it with aldehyde prefixation. The method used by Martin et al. in cephalopod nerves has been adapted for mammalian tissues. All nerve terminals o
