PS1005 Provide an overview of the principal structures of the midbrain‚ hindbrain and forebrain and their functions. The human nervous system consists of many structures. We distinguish between the central- and the peripheral nervous system. The two major subdivisions of the central nervous system are the brain and the spinal cord‚ which is found in the spinal column. The peripheral nervous system consists of the nerves outside the brain and the spinal cord. The spinal cord communicates

Project 2.1.3: Map-A-Brain Conclusion 1 Why is the story of Phineas Gage considered so extraordinary? What does his story teach us about the brain? The injury that occurred to Phineas Gage is extraordinary because it completely changed his emotions and mental characteristics‚ and did not damage him severely physically.He lived from the accident‚ and was physically the same person‚ but after it‚ all of his personal characteristics changed‚ turning him into a completely different person. This proves

Diseases and deciding if she should have extensive testing or going to the doctor and letting the doctor put Minnie on some kind of treatment plan. The parts of the brain that are affected by Alzheimer ’s Diseases is the frontal lobe‚ the temporal lobe‚ and the parietal lobe. The changes that occur leads to nerve cell death and tissue loss throughout the brain. Then over time the brain will shrink dramatically‚ affecting nearly every function or part. One part of the brain that is the hippocampus

Electroencephalogram (EEG)- An amplified recording of the waves of electrical activity that sweep across the brain’s surface. These waves are measured by electrodes placed on the scalp. 3. Computed Tomography (CT)- Series of X-ray photographs taken from different angles and combined by computer into a compsite representation

Part I Note: Parts II and III follow below‚ complete all three. Write a 350- to 700-word response to the following: Explain the communication process of neurons in the brain. List some common neurotransmitters and describe their effect on behavior. There are 2 neurons afferent neurons these carry messages to the central nervous system. Efferent neurons carry messages from the central nervous system. Neurons communicate through voltage changes. This can sometimes lead to quick action reaction

degenerative diseases such as parkinsons‚ brain development problems such as autism‚ blood flow issues including stroke and infection by bacteria and viruses. One of the pioneers of brain injury research was Pierre Paul Broca who reported inferior frontal gyrus impairments lead to a loss of ability to produce language after injury to this area. Since then‚ the approximate region he identified has become known as Broca’s area‚ and the deficit in language production as Broca’s aphasia. Another prominent

goals. The Brain The brain is compiled of two different major cores‚ the inner core and the outer core. The inner core can be separated into four areas‚ frontal‚ temporal‚ parietal and occipital regions. The outer core is one continuous cover on the left and right hemispheres of the brain. Inner Core The frontal lobe‚ located in the front of the forehead is the main control center for all of the muscles throughout the entire body. On top of that‚ it also is the master control

Abnormal activity in temporal lobes is usually due to past head trauma‚ infections‚ lack of oxygen‚ exposure to toxins‚ or can be inherited. SPECT findings‚ decreased activity in the temporal lobes‚ and at times excessive increased activity. Even though the six types have some commonality of symptoms‚ each type has its own set of symptoms and specific treatments

Information travels along the axon in the form of an electric charge called the action potential. terminal buttons Tiny bulblike structures at the end of the axon‚ which contain neurotransmitters
