Nicotine beliefs elicit dose-response reactions in human brains

admin

A recent study published in Nature Mental Health investigates whether nicotine-related beliefs influence brain processes in a dose-dependent manner. Researchers examine the influence of perceived nicotine dose on the human brain, using nicotine as a test case. The study finds that beliefs about nicotine strength can elicit dose-dependent responses in specific areas of the brain, without significantly affecting nicotine intake or metabolism. These findings highlight the significance of beliefs in modulating nicotine-induced brain responses and provide insight into the influence of attitudes and expectations on drug addiction and pharmacological treatments.
