Evoked potential

restricted to the brain and spinal cord. Their main function is to keep chemical environments for neuronal signaling balanced. Oligodendrocytes are our lipid-rich wrapping found in our nervous systems. Myelin has important effects on the speed of action potential conduction. Microglial cells are much smaller cells derived from hematopoietic stem cells. These cells have a lot in common with macrophage tissue. They are basically scavenger cells which remove cellular debris from any site of…

Study of the brain is significant in gaining insights on its structural and functional design and mechanisms which help explain the cause of various existing neurological and psychiatric diseases (Kotter, 2001). Consequently, the histological study of the nervous system and its components which underlies the understanding of the brain forms the basis and foundation of neuroscientific research (Annese, 2012). Important components of the nervous system include the spinal cord which consists of…

This essay will discuss the question of “Should people be allowed to eat fugu given the risks?”, with detailed explanation to the science behind fugu poisoning. The target audience is for anyone who is interested in eating fugu, anyone who eats fugu, and anyone who is interested to just know about how it works. Fugu eating has been around Japan since about 10,000 B.C . It’s one of the most historical food in Japan. However despite the taste of this delicacy, fugu is also highly poisonous. fugu…

The first main system is the central nervous system which consists of the brain and the spinal cord. There are three main sections of the brain; the forebrain which contains the cerebrum and the parts of the diencephalon (the thalamus, hypothalamus, and epithalamus most importantly), the midbrain which is a part of the brain stem, and the hindbrain which consists of the medulla oblongata, the pons, and the cerebellum. The cerebrum, the picture on the right hemisphere of the model’s brain, is the…

neuron’s ability to propagate action potential since calcium and sodium-dependent depolarization are inhibited (Bellingham, 2011). In contrast, it activates G-protein dependent processes, releasing calcium stores to counter inhibitory effects which may consequently lead to no effects at all unless in high dosages (Bensimon, Lacomblez, and Meininger, 1994). Furthermore, aminotransferases leading to toxic levels of ammonia causing unwanted brain damage is a potential side-effect of Riluzole…

The word «plastic» has a Greek origin (πλαστικός) meaning something that is capable of being shaped and/or molten. Similarly, due to its vast neuronal circuitry the human brain can be shaped by the environment and cognitive experience[38]. Brain plasticity (or neuroplasticity) describes lasting change to the brain throughout an animal's life course. For example, as it is described in the previous section, during fetal development the brain changes continuously, considering maturation of the…

Waves of sound energy race out from a loud object in all directions and that energy keeps moving through the air until it reaches your ears. That is when you then hear the noise of said loud object. The pinnae (the large outer flaps of your ears), gather all sounds coming from the different directions, they are shaped in a way that allows this. They then go on to channel the energy through into the ear canal. At the end of this ear canal is the eardrum. When the energy, also known as sound waves…

Our logic for choosing kinesin for developing CNS therapeutics is based upon our own research, which found that kinesins are transcriptionally upregulated during memory storage and that they are both necessary and sufficient to induce long-term memory storage (LTM) in the marine snail, Aplysia californica (Puthanveettil et al., 2008; Fig 1). Furthermore, other researchers have also discovered that an increase in specific kinesin function in the mouse forebrain improves working memory (Wong et al…

Working hard is the definition of paystation. It is not an easy job, and that’s why I love it. I especially love the challenge of running the register and cleaning the dining room, but making sure everyone who comes in is helped quickly and has to wait as little as possible. I never thought working at Hy-Vee would make a difference in my life, though. Throughout my time working at Hy-Vee, I have learned a lot about working hard and being efficient, and applying that to my life outside of Hy-Vee…

the body using electrical synapses. While neurons are made up off a cell body referred to as the soma, dendrites, and axon. Nerves consist of axons and sometimes nerve fibers, and each of those axons has the ability to produce an action potential. Action potential is a well-preserved message as a response to a specific stimulus that travels down the axon. Moreover, sodium/potassium pumps are located in the…
