For example, THC is able to alter the functioning of the hippocampus (see " Marijuana, Memory, and the Hippocampus ") and orbitofrontal cortex, brain areas that enable a person to form new memories and shift his or her attentional focus. As a result, using marijuana causes impaired thinking and interferes with a person’s ability to learn and perform complicated tasks. THC also disrupts functioning of the cerebellum and basal ganglia, brain areas that regulate balance, posture, coordination, and reaction time. This is the reason people who have used marijuana may not be able to drive safely (see " Does marijuana use affect driving? ") and may have problems playing sports or engaging in other physical activities.
Finally, for Wicksell the endogenous creation of money, and how it leads to changes in the real market (. increased real aggregate demand) is fundamentally a breakdown of the neoclassical tradition of a dichotomy between the monetary and real sectors. Money is not a "veil"—agents do react to it and this is not due to some irrational money illusion . However, for Wicksell, in the long run, the quantity theory still holds: money is still neutral in the long run, although to do so, we have broken the cherished neoclassical principles of dichotomy, money supply exogeneity and Say's law.
