Resumen de A pill to protect against stress?
While she was giving ketamine to mice with the symptoms of depression, Rebecca Brachman at Columbia University in New York stumbled across the idea whether there's way to boost humans' stress resilience and thus shield them from depression. Even though the ketamine-taking mice had been chronically stressed, when they were dropped in a pool of water--a one-off stressful event--they were unperturbed and swam to an exit. Mice not given the drug made no attempt to escape, a classic sign of depression in rodents. There was also no change in the ketamine-taking animals' cognitive abilities or metabolism--both of which are altered in human depression.
