Kgnu - How On Earth

This week on How on Earth, we speak with Dr Paula Hoffman, a neuropharmacologist - she's scientist who studies what drugs do in the brain- who works on the genetics of alcohol and other drugs of abuse. Paula reviews the action of alcohol on different neurotransmitter systems of the brain then describes some of the genetic issues which predispose people to risk for becoming alcoholics. Finally she talks about research done in her lab which has resulted in preliminary understanding of genetic networks involved.
