Listening to classical music regularly may give you a genetic advantage.
Finnish researchers examined the effects of classical music on the brain at the molecular level on both musically experienced (48) and inexperienced (15) people. Genetic activity increased for the "feel-good" hormone dopamine, as well as genes involved in memory, learning and synaptic activity. Genes associated with neuro-degeneration were less active. Only musically experienced participants exhibited these effects.
PositiveTip: Get "musically experienced" and regularly enjoy classical music for both genetic and mental health benefits. You can start with the Mozart concerto used by researchers.
Moderate canabis and ecstasy use reduce memory and attention in young adults.
The regular use of some illegal drugs may cause cognitive impairments. Two of these substances are "ecstasy" and "canabis". Recent research has focussed on attention and memory in a community-based sample of young adults derived from a large-scale epidemiological study. Subjects were sampled with varying degrees of lifetime drug use.
A dose-response relationship was found for poorer episodic memory function when ecstasy and cannabis were used. There was also a stronger tendency for attention to lapse with the higher use of these drugs.
PositiveTip: For maximum memory and alertness stay away from all illegal drugs.
