Is Hemisphere Is Specialised For The Perception Of Emotion

“The Human Brain”, by myPerspectives, is an informative article that claims that the brain is a complex organ that is truly impressive. The brain is a key part of the central nervous system, that controls the entire body’s activities, to simple things such as breathing. These actions are fired through neurons, that quickly travel through the spinal cord. Surprisingly, the brain transmits these messages at an unimaginable rate, at 150 miles per hour, through 85 billion cells, called neurons. These neurons can form up to 10,000 synapses, or connections to each other. By itself, the brain can create billions of synapses, which change the structure of the brain every time new information is learned. However, there is still much that scientists

The progress of neuroscience has been significant in the past 500 years. and with the advance of technology, there is yet a multitude of chapters left to write in the history books of neuroscience. The book The Tale of the Dueling Neurosurgeons: written by Sam Kean was an engrossing and captivating read. It gives the reader a better appreciation for the growing pains of neuroscience and provides an educational, albeit entertaining overview of the anatomy and physiology of the brain and nervous system. From the early life and discoveries of Santiago Ramón y Cajal and his fascination with Golgi’s method la razione nera, which allowed Cajal to deduct after observing

I read the article, “Secrets of the Brain”, found in the February 2014 issue of National Geographic written by Carl Zimmer. I chose this subject because I have been fascinated with the brain and how it works. The research of the brain has been ongoing for many centuries now. The history in this article is interesting. It explained how scientists used to understand the brain and its inner workings. For example, “in the ancient world physicians believed that the brain was made of phlegm. Aristotle looked on it as a refrigerator, cooling of the fiery heart. From his time through the Renaissance, anatomists declared with great authority that our perceptions, emotions, reasoning, and actions were all the result of “animal spirits”—mysterious, unknowable vapors that swirled through cavities in our head and traveled through our bodies.” (Zimmer, p. 38)

The nineteenth century saw an explosion in knowledge regarding the brain unlike any before. For centuries, the brain had been considered the seat of human intelligence. However, the brain of the classics was a singular organ of

The advocates of brain-based education support a varied group of educational practices and approaches, and they try to base claims about important practice in recently found facts about the human brain. They dispute that there has been remarkable new outcomes associated with the development and organization of the human brain and this work can enlighten educational practice in significant ways. (“Brain-Based Education”).

The brain is one of the most complex organ in our bodies. To learn about the brain scientists use electrical stimulation. Electrical stimulation is the use of electrical probes to determine functions of the brain. Clinical observation of patients have also helped scientists learn more about the brain. Case studies of different patients such as Phineas Gage have helped to learn about the different functions of the brain and how they work together to perform complex activities.

The human brain is an amazing device. It controls everything we do. It controls our bodies, how we communicate, how we function. Our brains our

According to the results, right-handed people are more likely to be leftward perceptual bias while the left-handed people are more likely to be rightward perceptual bias. Signifiying that right-handed people tend to choose the chimeric image in which the young qualities were demonstrated on the left side of the face compared to the left-handed individuals. Since the right hemisphere is more involved in making judgement of faces compared to the

I decided to write my literature after going through one of the textbooks in my physiological psychology course and remembered about the cerebral hemispheres, which receives sensory information from opposite sides of the body. This got interested in the topic of cerebral hemispheres and sensory information after a split brain operation. The split brain procedure is a surgical operation that’s used for people that have severe epilepsy that can’t be controlled by the drugs they take. In the brains of people with severe epilepsy, the nerve cells on one side of the brain are overactive and the overactivity is relayed to the other side by the corpus callosum, a bundle of nerve cells that connect certain parts of one side of the brain to the other. The corpus callosum enables the left and right side of the brain to share information so that both sides knows what the other is doing and perceiving. Both sides of the brain engage in out of control activity that stimulate each other, causing stereotypical seizures that recur throughout the day preventing the person from living a normal life. Neurosurgeons have discovered that severing the corpus callosum greatly reduces the often recurring seizures.

The primary structure in the cranial cavity is the brain which has a mass around 1300 grams and make up by approximately 100 billion neurons and 10 to 50 trillion neuroglia in adults (Tortora and Derrickson, 2011). The weight of the brain increases rapidly during the first four years of life and reaches the maximum weight around twentieth years (Gallucci et al., 2005). The brain is the portion of central nervous system that act as control center for registering sensation correlated with one another and with stored information, decision making, and actions. Furthermore, it also acts as a center for the intellectual, emotions, behavior and memories (Tortora and Derrickson, 2011).

This, I led me too a love of psychology. How wonderful was it that there was a whole science devoted just to that one mystical organ? Studying the brain, we can unlock the doors to human

We all know that the brain isn’t just a simple organ. Billions and trillions of connections or also known as synapses create those neurons that our brain consists of. The weight of each and every brain weighs about “3 pounds” (Lewis). It consists of “two percent body weight” (Lewis), and is larger in relation to body size than any other brain. Our brains are the “same structure as mammal brains”, and are both the “command center for the

This week we are learning about discovery and exploration and I believe the discovery and exploration of the brain are as immense as discovering and exploring the Universe. In” Psychology: Advances in neuroscience ("Secrets of the Brain," National Geographic, Feb 2014)”, author, Carl Zimmer, gives us a tour of some of the amazing research into the brain and the many immense leaps forward scientists are making in the area.

Franz Joseph Gall created the first comprehensive theory of brain localization in 1796. Phrenology is a pseudoscientific theory that asserts an individual’s personality and mental capacities can be determined by the shape of their skull (Cooter, 1984). “Organology” was the original term that Gall used to describe his science; it was Gall’s follower, T.I.M Forster, who coined the term phrenology (Van Wyhe, 1999). Gall’s contemporary, Joseph Franz Spurzheim, was responsible for the dissemination of Gall’s ideas to the United Kingdom and the United States (Selby, 1993). Gall inspired many “egotistical” men to promulgate phrenology, and it “attracted such men because of its promise of superlative intellectual authority with minimal effort” (Van Wyhe, 1999). Phrenology

Chapter 2 is centered on the early attempts to identify the brain’s components of emotions. Key researchers that are discussed are a Cornell neuroanatomist, James Papez, and aforementioned physician and neuroscientist Paul MacLean, who worked at Yale and the National Institutes of Mental Health. Together, this pair of researchers conducted seminal medial temporal lobe lesion experiments. The resulting idea was that the emotional brain is composed of a set of interconnected structures in the core of the brain. MacLean dubbed these structures as the “limbic system”. The function of the limbic system and it relationship to emotion was widely debated by many researchers.
