| Popis: | Golgi and electron microscope studies on the cat's LP-pulvinar formation of the thalamus reveal the presence of two characteristically different cell populations: principal (or relay) cells and Golgi type II interneurons. These two cell types show little if any difference, both at the light and electron microscope level, from the characteristics of the similar cell types and the ultrastructural arrangement found in the sensory relay nuclei. Characteristic synaptic glomeruli (or encapsulated zones) are found in abundance in the LP-pulvianr complex. Four different types of terminal profiles containing synaptic vesicles can be identified in these glomeruli:RL = large axonal terminals with spheroid vesicles;RL = small axonal terminals with similar vesicles (relatively rare in the glomeruli and abundant in the general extraglomerular neuropil);F 1 = probably axonal profiles with flattened vesicles (present both in the glomeruli and in the general neuropil); andF 2 = profiles interpreted as of dendritic nature and belonging to Golgi type II interneurons. The numbers, percentages of different types of terminal profiles and of various combinations of interprofile contacts have been determined. |
