Insular cortex

DMN comprise of a set of brain regions that are deactivated during a wide range of cognitive task. It is anchored in the posterior cingulate cortex and medial prefrontal cortex, with nodes in the medial temporal lobe and the angular gyrus. Research has suggested that the DMN is a robust network which can be readily identified in every individual. A failure to deactivate DMN activity during cognitively demanding…

State projection of Layer V of the Primary Somatosensory Cortex (1pt) Layer V projects to the dorsal column nuclei, as well as to the dorsal horn of the spinal cord; and to the striatum and brain stem in general. 15. What is the pathway of the projections of the Secondary Somatosensory Cortex (SII)? (1pts) Projects to the Insula which then projects to amygdala and hippocampus. 16. How the chemicals which released during tissue…

As previously learned in class, the definition of evolution is the change in variant frequencies in a population over time. The four forces that evolution acts on are mutations, gene flow, genetic drift, and natural selection. From an evolutionary psychology perspective, the physical structure of the brain has changed over time, thus allowing humans to develop complex behavioral patterns. When comparing brains with primates, humans have a larger and heavier brain. When compared to a…

The ability to express and perceive emotion serves an important role for human functioning in everyday environments. It can, for example, allow us to detect danger or respond to a person in need. A full understanding of how emotion influences behaviour has yet to be realized. Recent literature has demonstrated that exposure to emotionally arousing stimuli can alter the perceptual mechanisms of participants. The present experiments attempted to expand this research to examine cross-modal vision…

importance of this region being its positioning in the brain. The accumbens is located in close proximity to one 's motor system ( for movements), one 's limbic system ( involved in one 's emotions and learning) and finally it extends to one 's prefrontal cortex (controls one 's thought processes; including problem solving, making decisions and planning things). All of these regions work together in order to create "a critical interface between our emotions and our actions"; Therefore creating…

the author discusses how four different parts of the brain have physically changed to create a better quality of life for a meditator. The first part of the brain is the lateral prefrontal cortex, aka the Assessment center, which involves ration, logical, and balanced perspective. Next the Medial prefrontal cortex, aka the me center, processes information…

Classical music is more harmonic while rock music is more rhythmic. Rhythmic music makes listeners more passionate, raising adrenaline, while harmonic music makes listeners more contemplative. Studies have shown that exposure to rock music causes learning and memory retention problems because the rhythm acts in the same way a drug do. However, the brain does create a strong association between rock music and what is happening visually when you hear the song. So, regardless of conditions, when…

Stress disorder really is. We have to look at what areas of the brain are being affected. There are three regions of your brain that are triggered and change due to Post Traumatic Stress Disorder the hippocampus, amygdale, and the medial prefrontal cortex. The region that is affected the most because of trauma is the amygdale. The amygdale is an almond shaped mass of cells located in the temporal lobe of the brain.…

parts of the brain involved with fear and the response to it. The thalamus receives incoming data and decides where to send it. It is located deep within the brain at the top of the brainstem and under the cerebral cortex, near the center of the brain. It is connected to the cerebral cortex, hippocampus, and spinal cord to receive sensory information. The sensory…

Study after study shows that any physical activity leaves behind many positive benefits but how much exercise does that imply and what kind of benefits are likely to be seen or even felt. There is no right or wrong answer although the Department of Health and Human Services recommends a minimum of 20 minutes everyday doing moderate aerobic activity such as walking or mowing the lawn combined with 10 minutes of vigorous activity related to running or sports while mixing in 2 days of weight…
