The Brain / Psy 240 / Week Two The human brain is one of the most complex and fascinating parts of the body. The major regions of the brain are separated into three layers called the central core‚ the limbic system‚ and the cerebral hemispheres or otherwise called the forebrain‚ midbrain‚ and hindbrain. The forebrain houses the cerebrum‚ thalamus‚ and hypothalamus. The midbrain houses tectum and tegmentum. The hindbrain houses the cerebellum‚ pons‚ and medulla. From here the brain is divided

body The crossing of nerve fibers takes place in the brain stem. Thus‚ injury to the left cerebral hemisphere produces sensory and motor deficits on the right side‚ and vice versa. The Cerebellum The second largest area‚ is responsible for maintaining balance and further control of movement and coordination. The Diencephalon The diencephalon or interbrain sits atop the brain stem and is enclosed by cerebral hemispheres. The major structure of the diencephalon are the thalamus‚ hypothalamus and

B) The brainstem is responsible for higher level thinking skills. C) Damage to the brainstem is usually fatal. D) All twelve cranial nerves enter or exit from the brainstem. E) The brainstem is a relay for sensory input. Answer: c Level: 1 2. In the CNS‚ clusters of gray matter containing cell bodies

contains the cerebral cortex. The telencephalon also consists of many other structures such as the major fissures which are big grooves in a complex cortex it includes the longitudinal fissure‚ lateral fissure‚ and central fissure. It also consists of the most important gyri’s that are located in the frontal‚ parietal‚ and temporal lobes‚ respectively (Pinel‚ 2011). The gyri include the precentral gyri‚ the postcentral gyri‚ and the superior gyri which are the largest (Pinel‚ 2011). The cerebral commissures

What makes humans unique? How do Humans differ from other species? These questions have been on the minds of social scientists over the years. Some have said that humans are just like other primates. While some others have mentioned that humans did not exactly descend from chimpanzees or gorillas‚ but it might be possible that humans and other primates have shared a common ancestor. It’s true that they share a lot of similarities but on the other hand they also have a lot of differences. The three

Michelle Vallie Causes and Symptoms of Brain Aneurysm “An estimated 6 million people in the United States have an unruptured brain aneurysm‚ or 1 in 50 people” (Brain Aneurysm Foundation 2011). First of all‚ what is Brain Aneurysm? A brain (cerebral) aneurysm is a bulging‚ weak area in the wall of an artery that supplies blood to the brain. In most cases‚ a brain aneurysm causes no symptoms and goes unnoticed. In rare cases‚ the brain aneurysm ruptures‚ releasing blood into the skull and causing

Biochemistry and Thought Production A humans cognition and thought processes are based on biochemical reactions within the human body. Biochemistry is the function of chemicals and processes occurring within a living being. It can be used in many ways to explain how our thoughts are produced. Through the functionalist perspective mental states and brain states are combined to form a matrix of thought. Functionalists argue that environmental inputs and mental states play a pivotal role

(Interactive transcripts are also available on the TED web site.) Based on what you have learned‚ which of Kurzweil’s predictions do you agree with‚ and which do you doubt? Why? Please be specific. I agree with Kurzweil’s predictions about the communications revolution. Kurzweil states that‚ “The
