Laminat cytoplasmic bodies and annulate lamellae in the cat ventrobasal and posterior thalamus.

Abstract

AbstractLarge and small laminated cytoplasmic bodies are reported in neurons and dendrites of the ventrobasal and posterior (PO) nuclear groups of the thalamus of the cat. The bodies are more frequently seen in dendritic profiles than in nerve cell bodies. They differ in size, as well as in number and complexity of orientation of the constituent tubules. Their topographic relationship to endoplasmic reticulum, synapses and adhesion plaques is noted and their possible evolution is discussed.A single collection of annulate lamellae is described in the perinuclear soma of one neuron.
