In modern times there is almost no way to avoid the internet. With all of the technology constantly surrounding humanity it is a wonder that human interaction still exists. With technology being such a massive factor in everyday life it must have effects on the brain. UCLA scientists have found that key centers of the brain that control decision- making and complex reasoning are triggered while using technology, the results suggest that web search activity may help stimulate and possibly improve…

Effects of Substance Abuse in Adolescence Brain Development Erik Erikson’ psychosocial model of development, occurs in eight different stages. According to Erikson’s theory successful passage through each stage, ensures positive ability to develop and communicate with others. Unsuccessful development of a stage will create delay in later stages. However, transition through these stages can be accomplished at another time. According to Erikson the adolescence stage, occurs during the ages of…

Grayce Petruzzi Professor Chesire-Brown PSY-P 101 16 October 2015 Myth or Not? Before doing research on the topic if some people are “right-brained” or are “left-brained”, this statement means that if you are logical or analytical then you are left-brain dominant, while the creative and artistic types are right brain dominant. I believe this is a myth because the brain does use one brain region more than another for certain functions but does not support the statement above. For example, speech…

Literature Review Introduction In 2015, the Centers for Disease Control and Prevention found that stroke is the leading cause of long-term disability and the fifth leading cause of death for Americans (“Stroke Facts,” 2015). Despite this degree of prevalence, stroke mortality rates in the United States (U.S.) are among the lowest in the world. Between 1960 and 1990 there has been a 60% decline in stroke mortality (Sacco et al., 1997). In 2008 alone, The Centers for Disease Control and…

My Hemispheres and Me Our brain’s two hemispheres look alike, but they have different function. This specialization of the right and left hemisphere is called lateralization. In the past scientists learned about this functional specialization of our brain by observing people with brain damage or injury and examining they brains after death. Today scientist have other methods. They can monitor brain waves, blood flow, or glucose consumption in the brain to find out which part of the brain is…

Background In 2014, the American Association for the Study of Liver Diseases (AASLD) and European Association for the Study of the Liver (EASL) published a new set of practice guidelines for Hepatic Encephalopathy (Vistrup et al., 2014). These guidelines define Hepatic Encephalopathy (HE) as “a brain dysfunction caused by liver insufficiency and/or portosystemic shunting, and manifests as a wide spectrum of neurological/psychiatric abnormalities ranging from subclinical alterations to coma”…

The commonly held idea that some people are “right-brained” and others are “left-brained” is in my opinion, a myth. I think this because people do not utilize one side of their brain more frequently than the other. It is commonly believed by many people that those who are “right-brained” tend to be more creative, artistic, and emotional, while people who are “left-brained” tend to be more logical, analytical, and excel in mathematics. I have heard this idea throughout my education many times…

Parietal Lobe: The parietal lobe is vital for sensory perception and integration, including the management of taste, hearing, sight, touch, and smell. It is home to the primary sensory area, a region where the brain interprets input from other areas of the body. Because of the parietal lobe’s role in sensory integration, spatial reasoning, and language skills, damage to the parietal lobe can have a broad range of consequences. Occipital Lobe: The main functions of the occipital lobe are vision,…

Answer Choice “D” is the best answer choice. This patient has findings on axial diffusion-weighted MRI, which show high signal activity in the cortex of the temporal lobes and insula, much more marked on the right. This finding is consistent with a diagnosis of herpes simplex encephalitis (HSVE). An MRI of the brain is the preferred imaging study in patients with suspected HSVE. Proton-density and T2 images may be more helpful than T1 images. An MRI can noninvasively establish many of the…

The prefrontal cortex is responsible for the capacity for representational memory, one part of the development of delayed response, and it depends on the maturation of the frontal cortex. Trauma victims, particularly children, usually have difficulty with those functions (van der Kolk, 2003). Excessive subcortical activation with decreased cortical inhibition combines to leave vulnerability in regards to the nature of incoming information. As children must develop ‘object permanence’ to modulate…
