[Effect of 5,6-dihydroxytryptamine and 6-hydroxydopamine on the maze behavior of the snail Helix lucroum].
One-trial Y-maze test in snails did not reveal any predominance of the right or left alley choice. The choice of the right alley (but not of the left one) was accompanied by a slowing down of forward motion. After the administration of 10 mg/kg of 6-hydroxydopamine 24 hr before the test, right alley choice without slowing down became more frequent. Administration of 5,6-dihydroxytrypamine (10 mg/kg) caused a reduction of motion rate along all parts of the maze and an increase in frequency of the orienting head movements towards the alley to be chosen.
