Helps to solidify bad memories:

The researchers, led by pharmacology professor Norio Matsuki, gave mild shocks to lab rats to condition them to fear. As a result, the rats would freeze in terror and curl up the moment they were put in their cages.

Researchers then immediately injected the rats with ethanol or saline.

The researchers found that rats with alcohol in their veins froze up for longer, with the fear on average lasting two weeks, compared with rats that did not receive injections.
