This is in line with the evidence for a role of the left frontal lobe in positive emotions whereas the right prefrontal lobe plays a greater role in negative ones (Canli et al., 1998).

Another theory suggests that drug-opposite or opponent processes induce drug seeking by producing a hypofunctional state of reward pathways which leads to dysphoria or anxiety during withdrawal (32).

Aging brain

Age is a major risk factor for most common neurodegenerative diseases, including Mild cognitive impairment, Alzheimer's disease, cerebrovascular disease, Parkinson's disease and Lou Gehrig's disease. While much research has focused on diseases of aging, there are few informative studies on the molecular biology of the aging brain (usually spelled ageing brain in British English) in the absence of neurodegenerative disease or the neuropsychological profile of healthy older adults. However, research does suggest that the aging process is associated with several structural, chemical, and functional changes in the brain as well as a host of neurocognitive changes. Recent reports in model organisms suggest that as organisms age, there are distinct changes in the expression of genes at the single neuron level. This page is devoted to reviewing the changes associated with healthy aging.
