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. As we can see from Marina, despite the fact of the pain widespread all over her body previously was eventually subsided, her fear of being unable backs to running did actually intensified the perception of pain.
The drive for novelty and wonder in humans is a strong one. Whenever humans encounter novelty, the brain produces a pleasure drug known as Dopamine. Humans are hardwired to seek out surprise in order to reward themselves with this ‘novelty bonus’. 2. Play is delightful
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."
Although thinking and creativity was enhanced, it was believed that ayahuasca improve mood; while drug users all had different experiences using ayahuasca; ayahuasca use in patients increases openness to many creative ideas but was in decline when using one way to problem solve “In contrast, convergent thinking and mood are related in a negative way: more positive mood lowers convergent thinking.” (Kuypers, K. P. C., et. al 2016, Pg. 3401). Ayahuasca holds promise as a psychedelic due to its divergent properties while assisted in psychotherapy. Researchers find that ayahuasca users not only found a way to adapt to problem solving but also to cope with severe sentiments “The sub-acute effects could then be suited in a second, “integration” session in which patients
Addictive experience can additionally be focused around their mental solidness. Enslavement encounters are is focused around how a specific thing makes somebody feel.

Previous studies have looked at the Catharsis Theory, rumination, and distraction when studying anger and aggression. The Catharsis Theory states that if an individual vents their anger their psychological state will improve. In this theory, by acting aggressively you are purging those angry feelings, thereby, leaving you in a more stable state of mind. The theory also states that viewing aggression has the same effect. 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. For example, dextromethorphan (DXM) is a synthetic drug that is found in common over-the-counter drugs that can be safe and effective when used properly. If used improperly however, it can cause muscle spasms, blurred vision, increased heart rate, slurred speech, and anxiety. Despite this, DXM users continue to abuse the drug in the hopes of feeling a sense of euphoria and visual hallucinations.
Under normal conditions, noxious stimuli diminish as healing progresses and pain sensation lessens until minimal or no pain is detected. Persistent, intense pain, however, activates secondary mechanisms both at the periphery and within the central nervous system that cause allodynia, hyperalgesia, and hyperpathia that can diminish normal functioning.

The vinpocetine is a semi-synthetic supplement that is partly source from the periwinkle plant. The vinpocetine is derived from the vincamine alkaloid and is said to help treat patients suffering from depression, memory loss, speech impairment and tinnitus. This supplement is semi-synthetic as it is manmade where the vincamine is altered to obtain the vinpocetine. The extracted compound is used to help widen the blood vessel resulting to increase blood flow to the brain, which also increases oxygen level and glucose utilization in the brain. This contributes to improve mental performance and overall brain
