Mental fatigue impairs midbrain function in cocaine-addicted individuals, researchers find

Fatigue can make relapse more likely. In this study, a task designed to induce fatigue activated the midbrain in healthy subjects but not in cocaine-addicted subjects (top row). However, when testsubjects were first given a dose of a pharmaceutical drug that boosts braindopamine function (methylphenidate, bottom row), these effects completely flipped: There was some midbrain […]

Why does vivid memory ‘feel so real?’ Real perceptual experience, mental replay share similar brain activation patterns (2012)

July 23rd, 2012 in Neuroscience Neuroscientists have found strong evidence that vivid memory and directly experiencing the real moment can trigger similar brain activation patterns. The study, led by Baycrest’s Rotman Research Institute (RRI), in collaboration with the University of Texas at Dallas, is one of the most ambitious and complex yet for elucidating the […]

Reprogram With Healthy Habits and Warm Fuzzies: Trumping Addictions and Compulsions

By Patricia L. Gerbarg, M.D. and Richard P. Brown, M.D. Humans are incredibly adaptable, brilliant learners. Advances in neuroscience show that we have a brain that is capable of changing itself [1]. While this confers enormous survival advantages, it also burdens us with unintended consequences: We can be reprogrammed to take pleasure from and crave […]
