An example of illness that can result in anterograde amnesia is herpes encephalitis. This illness is believed to be the result of the retrograde transmission of the virus from the face following simple herpes (HSV-1) reactivation, along a nerve axon, ending in the brain (Whitley RJ 2006) The virus lies inactive in the ganglion of the trigeminal cranial nerve, it however remains unclear what exactly causes the reactivation and how it gains access to the brain pathway though its believed it may be a result of changes in the immune system caused by stress. It is also believed that the olfactory nerve may be involved in this particular illness, offering an explanation its preference for the temporal lobes of the brain, as it sends branches there. If left untreated after 96 hours permanent damage in
This theory has proposed there is a gating mechanism within spinal cord working in the pain perception which the gate will be facilitated and thus allowing the sensory input to reach our brain (Melzack & Wall, 1965). The impulse will then be interpreted by our brain and sends message which might causes either the gate to be opened wider causing higher intensity of pain or diminished the pain by closing it (Ciccarelli & White, 2012). There is psychological factor affecting in how the pain is prioritized by the brain (Sams, 2006). Melzack and Wall (1965) have proposed that sensation of pain is unlikely to be dissociated from our emotional experience which was extremely varied from the conventional theory of pain that focusing on the seriousness of injured tissues in that era.

The biological explanation of the brain in regards to drug addiction is interesting. According to the textbook, "Studies have found convincing evidence that drugs such as alcohol, heroin, and cocaine act directly on the brain mechanisms that are responsible for reward and punishment." When one use drugs, the drug stimulates the areas of the brain that create the sensation of pleasure and suppress the pleasure of pain, as, a result, the user receives reinforcement to engage in further drug-taking behavior. The psychological explanation of drug abuse, "Focus on either personality disorders or the effects of social learning and reinforcement on drug-taking behaviors." The sociological explanation on drug abuse and the symbolic interactionist perspective overlap.

Another theory on aggression is the Cognitive Neoassociation Theory.
Biological theories of crime causation once accepted the theory that man operates based on free will and rational thought when they choose what and what not to do (Siegel, 2000). Today, criminality is viewed as a function of people’s interactions with organization, institutions, and processes in society. All people have the potential to become criminals if they maintain destructive social relationships (Siegel, 2000). Biological theories of crime causation make the fundamental assumption that the brain is the organ of the mind and the location of personality. Franz Gall was the first Western writer to firmly locate the roots of personality in the brain (Schmalleger, 2012).
The amount of any substance ingested will correspond with the effect it will have on the body. Nonetheless, some psychedelic drugs have more intense effects than others.
