It can change everything about your life. About the Brain… When it comes to the brain it has multiple functions that it is able to do but there are different parts of the brain that control each thing. In the brain you have a frontal lobe, parietal lobe,…

What is a stroke? A stroke is a major medical emergency. It happens when the brain isn’t getting the oxygen that it needs, and the blood flow to your brain stops. This causes brain cells to die which can result in loss of memory, speech, and/or loss of movement. There are two different kinds of strokes, ischemic stroke and hemorrhagic stroke. An ischemic stroke happens when there is a blood clot that blocks a blood vessel in the brain, this is the most common type of stroke. Hemorrhagic stroke…

6) The monoamine theory of depression foresees the underlying pathophysiologic source for depression is the diminution of levels of norepinephrine, serotonin, and dopamine within the central nervous system (National Center for Biotechnology Information). Indication for this hypothesis is sustained with clinical trials and animal testing. Barchas, J., and Altemus, M. (1999) Monoamine Hypotheses of Mood Disorders Retrieved from http://www.ncbi.nlm.nih.gov/books/NBK28257/ 7) NOT DONE 8) The…

Resting membrane potential is the difference in voltage of the fluids inside a cell and outside a cell and the membrane is said to be polarized. According to the book the value of the resting membrane potential varies from -40 mv to -90 mv in different types of neurons. There are two essential factors that build and generate the resting membrane potential: the differences in the ionic composition of the intracellular and extracellular fluids, and the differential permeability of the plasma…

A. THE NERVOUS SYSTEM 1. What are the central and peripheral nervous systems? What structures are part of each? The central nervous system is made up of two parts, the brain, and the spinal cord. The peripheral nervous system is made up of two parts as well, the somatic nervous system and the autonomic nervous system. 2. What are Neurons? Describe the key parts of Neurons, including: Dendrites, Myelin, Axons, and Synapse. To keep it simple, a neuron is a nerve cell. Most neurons are very…

Greene’s YouTube video highlights and fights against what is real and what is not. His ideas are based on science and nothing more than what the brain is capable to do. Also, what the brain is not able to do and that we also don’t know about. According to him what is real and what is not is based on perception, Greene’s intentions in ‘Perception – The Reality Beyond Matter’ Illustrate a certainty of which path most people want in life and it brings a general idea of a realistic path everyone…

of the brain, there is not as much activity when the person is depressed. The thalamus sends sensory information to the cerebral cortex. This is also involved in problem solving and thinking. The basal ganglia organize motor behaviors and the occipital lobe receives and sends visual messages. People with Bipolar Disorder often have a hard time reading, writing, and completing motor skills such as gluing or cutting. Last, the hypothalamus can also be affected because there are more neuropeptides…

Zombies are depicted as slow, unintelligent, and driven by hunger. The multiple videos, such as The Walking Dead, Night of the Living Dead, Warm Bodies, and Shaun of the Dead portrayed different attributes among emotion, physical, and psychological behaviors. The typical zombie behavior can be explained by the exploration and examination of the various parts of the brain. Firstly, zombies have the physical trait of a staggering walk in which their legs are stiff and their arms either are…

The nervous system makes it possible for animals to know and react to the environment around them. A change or event that evokes a specific functional reaction in an organ or tissue is a stimulus. There can either be an internal or an external stimulus. Internal stimulus being something like hunger or pain, while external is more along the lines of a sound or an odor. The nervous system interprets stimuli and orders other organ systems to respond. The nervous system does so through using sensory…

One injury can damaged the brain and its functions. For example, the temporal lobe. Temporal lobe is located at the bottom front part of the brain. One of the major function of the temporal lobe is memory. Damage to temporal can cause memory problems. Due to the book I am reading called (The Book of Unknown Americans by Cristina Henriquez), the brain injury effect I will be focusing on…
