Alcoholism At Large

Effects of 'hair of the dog' studied

Neuroscientists from the University of Southampton's School of Biological Sciences investigated alcohol dependency and withdrawal in worms and found that while withdrawal symptoms could be relieved by small doses of alcohol, easing the effects could increase dependency. The study was published in the journal PLOS ONE on May 3, 2010.

The 1 mm long C. elegans worms used in the study exhibited alcohol-dependent behavior similar to humans. In humans, the symptoms are manifested in anxiety, agitation and, in extreme cases, seizures. The worms became overactive in withdrawal and showed spontaneous and deep body bends--a behaviour rarely seen in "teetotal" worms.
