Question

Experiment on mechanism of actions of low concentrations of alcohol induced hyperactivity in zebra fish larvae.

Answer 1

The experiments involving zebrafish showed that the alcohol acts as both the CNS (Central Nervous System) stimulant and depressant at different concentrations. The zebra fish larvae exposed to low concentrations of alcohol (such as ethanol) shows increased locomoter activity than the control larvae who were not exposed to alcohol. On the other hand, increased concentrations of alcohol decreased the locomoter activity of the larvae.

This shows that alcohol at low concentrations act as CNS stimulant while at high concentrations act as CNS depressant.
