If the captivating melody could easily take the edge off of the most atrocious monster, then, what are other significant impacts of euphonic sounds for the society? Many are gradually acknowledging the underlying implications of harmonies to their percipience, as seen in the ironical case of Ludwig van Beethoven. The composer of some of the most celebrated music history, such as Moonlight Sonata and…

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…

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…

Cannabis, or cannabis sativa, originated in Central Asia and has been used for its psychoactive properties for many years (Iversen, 2008, p. 6). It affects the brain of adolescents and adults differently through the binding of CB1 receptors due to distinctions in neurocognitive development. There are certain changes in gray and white matter densities, brain volume, as well as endocannabinoid concentrations. This creates aberrations in cognition and memory performance. Cannabinoid’s structures…

Literature review It is a stark reality that as people age, their cognitive abilities tend to decrease, including memory capabilities. At the present, scholars have identified three types of memory stores: sensory memory, short-term memory (STM), and long-term memory (LTM). Memory includes primarily three processes: encoding, storage, and retrieval. Additionally, in order to these processes occur favorably, attention to the information or stimuli presented is vital (Garrett, 2011; Sternberg,…
