Human brain

The use of methamphetamine may result in severe psychological effects due to the impairment of the brain, through dopamine depletion as the main example. Australia has one of the highest rates of methamphetamine use in the world, with around 2.5% of Australians having used methamphetamine in the last 14 years. As methamphetamine enters the brain, dopamine is released in concentrations ten times higher than normal. This excessive release of dopamine produces pleasure and cause the user to…

ever wondered how the brain works or how it is connected? Outside the brain there appears to be a handful of pink and gray muscles. However, as you enter the human brain, it reveals an extremely complex circuit, connecting you with the rest of your body. The brain contains almost 100,000 miles of blood vessels and billions of cells. It is the consummate library of information, remembering data and processing it as quickly as 11 million bits per second (The Human Brain). The brain is a very…

A human’s cognitive ability is unlike any other animal on the earth. Compared to other animals, the human brain possesses more neurons and synapses, tallying eighty-six billion and one hundred fifty trillion respectively. The wiring of the brain and its connections are responsible for human’s superior cognition. Thus, the reason neuroscientists pursue research of neural connections is obvious; neural connections are the fundamental basis of individual expression. Many famous neuroscientists,…

The human brain is a product of millions of years of evolution. This organ has enabled monumental achievements since the existence of humankind and was important the development of tools and technologies necessary for the progressive advancement of civilization. Technologies such as water canals for irrigation and agriculture, automobiles and other vehicles for transportation and visiting areas of the world unreached for many millennia, and usage of ancient scriptures and eventually the…

concise way of understanding the numerous, undeniable correlations between brain structures and identity. Current research has already shown key facets of human experience to be directly represented in the brain. Computers are closing in on matching our ability at certain tasks that are essential to the human experience. Accepting a neuroscientific model of mental illness helps patients, putting the burden on their brain instead of their mind. Evidence for the efficacy of neuroscience in…

We all know that animals have a special place in the human heart. But how do they affect the brain? A team of researchers at Caltech found individual brain cells that react to animals but not to other humans, places or things. These cells were found in the amygdala, an area of the brain that is involved with emotions. These cells react to any kind of animal, such as dogs, cats and even spiders. It is said that one reason modern day humans have these cells could be that animals posed a threat to…

discusses what he has learned about the human brain, and in this paper, I summarize the main ideas and points that are brought up, while adding my own comments on its contents. The brain is known for being the most mysterious organ. Our current technology and methods of observation and experimentation are not advanced enough to unveil all that there is to know about it. Most of our known current methods include using antennas to pick up radio waves emitted by our brains, and other devices that…

The human brain is complex. No matter how much scientists study it, there always seems to be more to learn about the human brain. Sometimes it seems the more we learn about the brain, the more we realize just how much we still do not understand. While this is by no means a complete explanation of everything going on neuroscience, here are three recent medical studies connected with the brain: Brain Scans and Depression Recently, researchers at King’s College London and The University of…

Daivez Bell & Taylor Jones The Brain Thang/ Gorelephant 10/5/16 Vocabulary Brain Size: The weight of the brain, compared to one another. Cerebrum:(incorporate the four lobes) most anterior part of the brain located in the frontal area of the skull consisting of two hemispheres, left and right, separated by a fissure. It is responsible the complex sensory and neural functions. Cerebellum:The part of the brain located behind the top of the brain stem and has 2 halves. It controls…

This article encapsulates the research of Professor Roger Whitaker which suggests that the evolution of the human brain is related to the concept of examining one another and making decisions as to whether we want to help each other or not (Science Daily 2016). The results of a test involving computer simulated 'donation games, ' revealed the complexities of decision-making strategies for humans and established why certain behaviours among individuals start to strengthen over time. The research…
