According to biological theories of criminality, what chemical factors in the body may account for increased aggression? Provide an example.
What we punt into our bodies can have a great effect on our emotions, thoughts, and actions. Some chemicals are introduced into our bodies through food or drugs and some chemical imbalances are natural depending on the person and their body makeup. "Bio criminology has made some significant strides in linking violent or disruptive behavior to eating habits, vitamin deficiencies, genetic inheritance, and other conditions that affect the body"(Schmalleger, 2012). Hypoglycemia or low blood sugar where too much insulin is present in the blood has been attributed to odd and sometimes criminal behavior by reducing the mind’s capacity to reason effectively or to judge the long-term consequences of behavior. Excess consumption of refined white sugar can lead hyperactivity, aggressiveness, excitability, and impairment of the ability to make reasoned decisions and may cause an otherwise 'normal' person to act out violently or commit a crime they otherwise probably would not commit. This has even stood up in the court system with a reduced sentence of a police officer convicted of murdering two people on the grounds that his mental state was unbalanced due to a huge consumption of sugars and junk food.
Other chemical factors in the body that may account for increased aggression can be an increased level of testosterone. “The male sex hormone testosterone has been linked to aggression. Most studies on the subject have consistently shown a relationship between high blood testosterone levels and increased aggressiveness in men” "(Schmalleger, 2012). An increased level of Serotonin in the blood has also been linked to violent acts in people. Other chemical factors that may increase aggression can be alcohol and drug use, steroids, low cortisol levels, hormone’s, medications, foods, and overall diet.

    The two neurotransmitters that are believed to be the most associated with aggression are low levels of serotonin and high levels of dopamine. These two chemicals allow impulses to be transmitted to another area; therefore all behaviours are influenced by neurotransmitters. There is also the influence of the amygdala, which controls the emotional responses, the hypothalamus, which coordinates both the autonomic nervous system and the activity of the pituitary and the frontal cortex.…

    Neurotransmitters are chemicals that enable impulses within the brain to be transmitted from one area of the brain to another. Serotonin is thought to reduce aggression by inhibiting responses to emotional stimuli that might otherwise lead to an aggressive response. Low serotonin in the brain has been associated with an increased susceptibility to impulsive behaviour, aggression and even violent suicide. A meta-analysis found that serotonin depletion leads to impulsive behaviour which can cause aggression. The second neurotransmitter is dopamine but the dopamine-aggression link is not as well established as with serotonin. Increases in dopamine activity via amphetamines have been associated with more aggression, and antipsychotics reducing dopamine activity have been shown to reduce aggression in violent delinquents.…

    Criminologist David Rowe was one of the primary leaders in a movement to bring the discussion of biology back to criminal justice which occurred in the late 1990's before this both biological and individual traits were largely ignored by criminologists. Now biological and individual traits are influential in large part due to Rowe whom published a book titled “Biology in Crime” in 2002. In this work Rowe contends that genetic factors affect individual traits due to their impact on the central nervous system and autonomic nervous system and that their is a physiological relation to a heightened amount of violence when these systems are thrown off and their is evidence that criminals may have deficits in the per-frontal cortex of the brain and their is an association between low…

    A gene called MAOA is associated with aggressive behaviour, it regulated the metabolism of serotonin, and additionally low levels of serotonin are associated with aggressive and impulsive behaviour. A study from a Dutch family with a history of violence including rape and arson found low levels of MAOA in their blood. It showed that the men had a defect in their MAOA. This study shows that the gene MAOA is associated with aggression, this means that some genes can influence the susceptibility to aggressive behaviour, however it is not certain that one gene can determine aggressive behaviour, however it is likely that many genes can contribute to human behaviour rather than one single gene.…

    This is a statement that researches have long sought the answer for, it all boils down to nature versus nurture. Is there a clear answer? I can honestly say now that I do not believe so, after evaluating both sides I see that nature and nurture seem to play an almost even role. Therefore, I do no think it is fair to determine this question with a yes or no answer, instead I hope to present the facts and allow others to make a judgment based on those. When beginning my research I had the advantage of working with top psychiatrists in my area to try and determine the cause of criminal behavior, and I realized very quickly that there are two very convincing opposing sides and no…

    The biological explanation for aggression states that aggression is innate behavior in people and the environment around them does not cause it. Neurotransmitters in the brain, chemicals that allow impulses to be transmitted from one area to another, can be used to explain why some people are aggressive. There is evidence to suggest that the neurotransmitters serotonin and dopamine are linked to aggression, low levels of serotonin and high levels of dopamine. Serotonin is a hormone that makes you happy; it helps to reduce aggression and inhibits responses to emotional stimuli that could potentially lead to aggression. Low levels of aggression are associated with increased susceptibility to impulsive behavior, aggression and violent suicide. Some drugs can alter the serotonin levels in our bodies and cause increased aggression levels. Dopamine is another hormone in the body that is associated with aggression, however the link between dopamine and aggression is not as well established as the link between serotonin and aggression. Increased levels of dopamine via amphetamines can be linked to increased aggression levels. Anti-psychotic drugs that are used to reduce levels of dopamine in the brain reduce aggressive behavior in people.…

    Cesare Lombroso was an Italian criminologist of the mid to late 1800s. He rejected the Classical School, which believed that crime was a characteristic of human nature and instead believed that criminality was inherited. From this belief, he developed a theory of deviance in which a person’s bodily constitution indicates whether or not an individual is a "born criminal." These "born criminals" are a throwback to an earlier stage of human evolution with the physical makeup, mental capabilities, and instincts of primitive man.…
