The effect of injection of serotonin (5-HT), dissolved in 2 mul of bidistilled water, into hippocampus was studied in rabbits with chronically implanted electrodes and cannulas. Bioelectric activity of gyrus cinguli, amygdaloid nucleus, and dorsal hippocampus was recorded. 5-HT (10--20 mug) inhibited the electrical activity of the structures investigated, and this inhibition was accompanied by a suppression of locomotor activity or sleep.

Brain tissue from rats perfused with a mixture of glyoxylic acid and formaldehyde was frozen and sectioned in a cryostat. The cryostat sections were incubated in glyoxylic acid, dried and reacted with formaldehyde vapor. Using this technique cortical noradrenaline and dopamine containing nerve terminals could be visualized with high sensitivity in a reproducible way. The importance of several critical parameters was evaluated and it was found that the incubation of the cryostat sections in glyoxylic acid effectively inhibited the diffusion of catecholamines, particularly dopamine. Thus the fixation effect of glyoxylic acid was considered important besides the fluorophore formation. This modification of the Falck-Hillarp fluorescence technique is rapid, simple and reproducible and might be of value especially for quantitative measurements of the fluorescence.
