Abstract

A morphometric analysis of the effect of LSD on synapses was performed in the habenulae and the interpeduncular nucleus of the frog. The OsO4-fixed nervous tissue was treated with ethanol phosphotung-stic acid (EPTA). Intersection of lattice lines with synapses were counted as a proportion of the total length of lines. LSD-treated frogs had a higher total area of synaptic contact than control frogs. Exocytosis profiles were observed only in LSD-treated frogs. Other qualitative changes in the ultrastructural characteristic of synapses were appreciable after LSD administration.
