very violent and homicidal individuals,” (Are Murderers…, 2015). He and his team discovered that in the brains of numerous murderers there was a reduced activity in the pre-frontal cortex (area that controls the emotions) and overactivation in the amygdala (area that generates the emotions), which concluded that the murderers’ brains make them more prone to anger, but less able to control…

The mind is a powerful thing. It can change a person’s way of seeing the world, tasting, feeling, smelling, and hearing. It has the ability to change every sense that we use to experience the world around us. Dissociative Identity Disorder is where a person has more than one identity. They can show symptoms such as mood swings, amnesia, self-destructive behavior and more mental issues. This disorder changes the way the patient perceives the world in the way that each identity is different. One…

Article Summary In the article by Ezzati, Zimmerman, Mindy, Katz Sundermann, Smith, Lipton and Lipton (2014), the goal was to look at the relationship between pain and hippocampal volumes in older cognitively intact adults. Specifically, this study was looking at differences in volume in subparts of the hippocampus as related to pain. This study looked at 86 adults over the age of 70 with a mean age of 80.2 years. Additionally, 53.8% were women, and 54.7% were white, and the sample had a mean…

INTRODUCTION A psychopath individual is known to act very impulsively, with disregard for others emotions, and against common social norms.5 Psychopathy is a mental health disorder that causes patients to exhibit lack of compassion and concern for others.2 Although there is a lot of information available to the public about how a psychopath acts, there is not much research done on why certain individuals exhibit psychopathic behaviors. Psychopaths exhibit certain characteristics and the…

Morphine is a drug that is used for pain relief. It acts on the central nervous system to decrease pain. The drug can be given in many forms, such as through the mouth, insertion into muscle, under the skin, intravenously, into the spinal cord, and rectally. This drug can be used for both chronic and acute pain. A person who has recently undergone surgery or a pregnancy are examples for why someone may choose to consume morphine. Morphine can increase the pain tolerance for a person who is…

The behavior of teenagers is explained with compassion and supportive insight in Why Do They Act That Way? by David Walsh, Ph.D. A book written for parents to help understand the behavior as teenagers change, it provides information that is valuable for educators as well. In explanations about processes of the brain that exceed normal growth, to windows of opportunities, to emotions and sexual identity, the book continually provides insight and tools for helping teenagers during this period.…

(arcuate nucleus), PVN (paraventricular nucleus), LHA (lateral hypothalamus area), VMN (ventral medial nucleus), and DMV (dorsalmedial nucleus) at the hypothalamus; the NTS (nucleus tractus solitarii) at the brainstem; the NAcc (nucleus accumbens) and amygdala in the prefrontal cortex; and the cortex. (B) The major appetite signal reception and integration occur in the hypothalamus. In the ARC, the NPY/AgRP neuron (green) produces NPY and AgRP while the POMC/CART neuron (red) produces POMC and…

as damaging. Physiological maltreatment has been associated with low self-esteem, lying, misbehavior, underachievement in school, criminal behavior, aggression, and murder (Feldman, 2014). Additionally, it can lead to reductions in the size of the amygdala and hippocampus; thereby negatively affecting memory, decision making, and emotional…

because it is addictive, as many people think, but because the user can experience its effects, flashbacks, even after using it for days, sometimes even years (“LSD”, p. 6). The main effect that this drug has in one’s body is over stimulation of the amygdala, which causes over production of one of the most popular and powerful neurotransmitters in the brain, dopamine. This creates a sensation of relaxation for the user, also, the neurons in the prefrontal cortex are affected and the perception…

learning. Biologically a child that has suffered trauma is wired to remain in a self-protective defense mode (De Thierry, 2015) during which the brain remains in flight, fight or freeze readiness in order to survive a real or perceived threat as the amygdala inhibits the neo-cortex’s ability to act rationally and logically. This is due to what Perry (2006) described as the neurosequential model, “where the impact of early adversity and complex trauma in the context of neglect and abuse links…
