Map of the United States (including Alaska, Hawaii and Puerto Rico), showing the mean annual temperature and the magnitude of the β coefficients from the obesity-adjusted meta-regression analysis, per state or territory over the period 1996–2009. The β coefficient from meta-regression analysis, representing the difference in diabetes incidence rate per 1 degree Celsius increase in temperature; red circles indicate a positive β coefficient, while blue circles indicate a negative β coefficient. Adjusted for the effect of time passage. Diabetes incidence rate is the age-adjusted diabetes incidence rate per 1,000. Image credit: Lisanne L. Blauw et al, doi: 10.1136/bmjdrc-2016-000317.

Dopaminergic system and reward processing: dopaminergic neurons are located in the midbrain structures substantia nigra (SNc) and the ventral tegmental area (VTA); their axons project to the striatum (caudate nucleus, putamen and ventral striatum including nucleus accumbens), the dorsal and ventral prefrontal cortex; the mesolimbic dopamine pathway mediates the psychopharmacology of reward, whether that is a natural high or a drug-induced high, and is sometimes referred to as the pleasure center of the brain, with dopamine as the pleasure neurotransmitter.
