At the level of the central nervous system an aqueous extract of the marine microalga Chlorella stigmatophora (Butcher) (Chlorophyceae) showed anti-dopaminergic-type activity in assays of its effects on spontaneous motor response, rectal temperature, motor coordination, amphetamine-induced hypermotility, exploratory conduct, muscle relaxation, catalepsy,(More)
We report the effects of aqueous extracts of the microalga Skeletonema costatum Greve (Cleve) (Bacillariophyceae) on spontaneous motor activity, rectal temperature, motor coordination, amphetamine-induced hypermotility, exploratory behaviour, muscle relaxation, catalepsy, conditioned avoidance responses, oxotremorin-induced cholinergic syndrome, and(More)
In the course of our continuing pharmacological studies of marine microalgae, we look now at Tetraselmis suecica Stewart (Prasinophyceae) and Isochrysis galbana Demart (Haptophyceae), assessing the effects which aqueous extracts of these algae exert upon the central nervous system. To this end, we have tested for effects upon the following: spontaneous(More)
