Risky decision making on brains of methamphetamine users examed with imaging

Posted Posted in brain, Health

Methamphetamine users showed less sensitivity to risk and reward in one region of the brain and greater sensitivity in other brain regions compared with non-users when performing an exercise involving risky decision making. Deficiencies in decision making are linked to addiction. Chronic methamphetamine use is associated with abnormalities in the neural circuits of the brain […]

High moral reasoning associated with increased activity in the human brain’s reward system

Posted Posted in brain, Health

Individuals who have a high level of moral reasoning show increased activity in the brain’s frontostriatal reward system, both during periods of rest and while performing a sequential risk taking and decision making task according to a new study from researchers at the Perelman School of Medicine, the Wharton School of the University of Pennsylvania, […]

Comprehensive sequencing program shows promise of precision medicine for advanced cancer

Posted Posted in Cancer, Health

The average metastatic cancer has more genetic mutations than are seen in early stage tumors, a new study finds. What that means: To make precision medicine a reality in cancer care, you need a real-time, comprehensive approach that looks at the metastatic tumors and sequences to a level of detail beyond most commercial tests. In […]

Firmer, fitter frame linked to firmer, fitter brain

Posted Posted in Health

Scientists have observed that more aerobically fit individuals have better memories. To investigate this phenomenon, they used magnetic resonance elastography (MRE), which measures the firmness and elasticity of organs, and found that fit individuals had a firmer, more elastic hippocampus — a region of the brain associated with memory. The method could provide early diagnosis […]
