neocortex” (Brown, 2011, p. 325). Fish were believed to have a small paleocortex in their forebrain, therefore, structures such as the hippocampus, which is responsible for memory, the cerebral cortex, responsible for processing information, and the amygdala, which is responsible for conditioned learning would not be present in the telencephalon (Hines, 2016 April). However, recent studies have shown that the brain structures for fish are as equally as complex as those of “higher” vertebrate…

non-densentized people, such as less amygdala activation. Their sensitization will grow at first and then decay to desensitization (Watt,…

information travels along the olfactory nerve to areas of the cortex and amygdala (Gazzinga, Heatherton & Halpern, 2016). The amygdala is right in front of the hippocampus and is mainly focuses on emotion (Gazzinga, Heatherton & Halpern, 2016). It plays a role in the emotional reaction to a stimulus (Gazzinga, Heatherton & Halpern, 2016). In my case, I would have a happy reaction to the stimuli of the smell of my uncle's cologne. The amygdala took the information from the receptor after I…

individual's ability to swallow, breath, and regulate heartbeat. Some autonomic functions may be impaired. Hippocampal injury will affect mood, the ability to create and store new memories, and may cause confusion and disorientation. Injury to the amygdala may cause increased anxiety and depression, and will affect memory and emotional sensitivity. Damage caused to the pituitary gland has many harmful effects such as, irregular growth rates in children, sex drive irregularity, body temperature…

So what exactly is ‘motivation’? - Well, motivation may be described as an internal process that makes a person move toward a specific goal. Motivation, like intelligence, can’t be directly observed. Instead, motivation can only be inferred by noting a person’s behaviour. Motivation can be described in many ways. According to psychology researcher, Kendra Cherry, “motivation is defined as the process that initiates, guides, and maintains goal-oriented behaviours”. Motivation is what causes us…

This can be linked to the Interactions of the Sociomotional system that is located in the limbic system, including the amygdala and prefrontal area, and the cognitive control system located in the prefrontal and parental regions (Steinberg, 2010A, 2010b). Risk taking in adolescence can involve substance abuse, binge drinking, and impaired driving. Risk taking can be major…

After reviewing the case of 28-year-old Owen, it is evident that he suffers from an anxiety disorder due to the simple fact that he has feelings of extreme nervousness that are interfering with his job. However, this is not his only symptom of anxiety he shows. Anxiety is usually not the only mental disorder one encounters at a time and he does show symptoms of other mental disorders as well. After reading Owen’s case the generalized anxiety disorder (GAD) stands out. GAD is a serious and common…

1. Neurons are the building blocks of the nervous system. Neurons communicate through synapses. The nervous system transmits all messages to the brain. The messaging process moves in one direction to the cell body, where the cell body transmits an electrical pulse to the neurotransmitter this creates an impulse. 2. Throughout the normal day you use multiple parts of your brain. An activity that uses more than ten parts of your brain at once is if you hold your hand over a flame. Your Frontal…

An article titled “One Reason Teen Respond Differently to the World: Immature Brain Circuitry”, it stated that, “As the teens got older, the center of activity shifted more towards the frontal cortex and away from the cruder response of the amygdala.”(Spinks 1). This shows that when a teen brain is developing, the part in which the teen uses switches to a new part, which is now the frontal cortex. A video called “Teen Brain: Under Construction” says that, “Teens are having confrontations,…

the brain affected is the hippocampus, this results in a gradual decline of short-term memory function and thus this is one of the first symptoms seen in Alzheimer patients. After the hippocampus the amygdala is usually affected, the amygdala is linked to the limbic system. Deterioration of the amygdala impairs an individual’s ability to process and memorise emotional reactions (Intech, 2012). As the disease advances it spreads through all the lobes and areas of the brain, which leads to a…
