Temporal lobe

For several years the frontal lobes, known to play a role in higher-order cognitive functioning, have been thought to contribute to episodic memory (EM) – a contribution in which researchers have recently made efforts to delineate. Here I will evaluate the notion that frontal lobes contribute to EM, and suggest reasons as to how it might do this. Lesion studies We can look at lesion studies to assess the contribution of the frontal lobes to EM. Unlike cued-recall and recognition tasks (which…

limbic underactivation which, “indicated that some of these people lack the ability to generate basic emotions that keep primitive killer instincts” suppressed (Brandt, 2007). Other researchers (Brandt, 2007) see similar deficits in scans of the frontal lobe, which is the part of the brain that deals with judgement calls and impulsive actions.James Blair, "believes that the amygdala forwards the wrong signals to the frontal cortex." (Brandt, 2007) However, there are scientists (Brandt, 2007)…

science is today, doctors and scientist still have many questions about the human brain, only having limited answers. “The brain made up of specialized functions that work together, and it is then divided into several lobes. All which have an important role”. (Webmd) The parietal lobes, manage sensations, and body movements like our…

Dementia affects an estimated 3.8 million people around the world. It is most common in the ages of sixty five-years and older. It is also the sixth leading cause of death in people of the United States, and the fifth leading cause in people over the age of sixty-five. Dementia can start early, and be a very slow process that is evident throughout the rest of the patient’s lives. There are currently no cures for dementia, but there are treatments to help some of the symptoms that go along…

Eigenvector centrality, which a measure utilized in graph theory, connectivity was obtained. The results manifested connectivity decline in left ventromedial prefrontal cortex (vmPFC), bilateral midcingulate cortex (MCC) and right superior parietal lobe. An increase in functional connectivity was visualized in bilateral cerebellar regions I to VI. Further a correlation of WML score and Eigen value centrality map informed a decrease in connectivity in bilateral vmPFC, PCC, left supplementary…

Magnetic Resonance Imagining (MRI) measure the frequency of magnetic-resonance signal. These signals can be measured at the same time, and their location is sorted based on resonant frequency. deCharms (2008) alikeness the MRI process to hearing several notes on a piano concurrently and then separating out the individual keys that produced each note based on the pitch of the note. MRI measures simultaneous signals emitted from an individual (just like the piano) and the origins of each signal…

Perdurantism is a solution to the problem of change which suggest that objects are four dimensional. Lewis would suggest that the objects have both temporal and spatial parts. While the spatial parts remain, the temporal parts can change. In other words, objects persist through time and change by having temporal parts. In an effort to understand why perdurantism exists, I will describe the circumstances leading to its creation, which will include a description of the elements of change and the…

One of the first studies that looked at the effects of gaming on the dopaminergic pathway was a study by Koepp and colleagues (1998) that took positron emission topography (PET) scans of eight male participants while they were playing a video game. The authors found that there were greater dopamine increases in the ventral striatum (where the NAc is located) in the experimental condition (playing the video game) than in the control condition (looking at an empty screen). Furthermore, while…

In the world today, there are about 5000 languages spoken. Where the languages originated from is the unknown factor that the humans have been studying for the past two centuries. Experts have linked the similarity of languages by the shared words, sounds, or grammatical constructions. There are specific names classified for people who speak a certain number of languages. People who speak one language are termed monolinguals. People who speak two languages fluently are termed bilinguals. People…

(AnatomyExpert, 2014). 2. Nasal Cartilage a. The nasal cartilage articulates with the ethmoid bone to anteriorly separate the nasal passage into two halves (Starkey, Brown, & Ryan, 2011). 3. Zygoma a. The zygoma is a sturture that fused to the maxilla and the temporal bones to form the prominent zygomatic arch beneath the eyes (Starkey, et al., 2011). 4. Maxilla a. The main functions for the maxilla bone are housing the teeth, forming the roof of the oral cavity, forming the floor and lateral…
