Presented by Alexia DeLara, Vanesa Mesic, . Joseph Ekofo, Amber . Tinagero, . and Jerilyn Curtis. What is ALS?. ALS is a rapidly progressive idiopathic neurodegenerative disease primarily targeting voluntary motor neurons, which may result in muscle weakness, paralysis, and respiratory failure. and John . Basl’s. Account. J. Blackmon. Neuron Replacement. Could a synthetic thing be conscious?. A common intuition is: Of course not!. But the Neuron Replacement Thought Experiment might convince you otherwise.. 6.5 Nerves, Hormones, and Homeostasis. How do neurons communicate and relay information?. http://www.pennmedicine.org/encyclopedia/em_DisplayAnimation.aspx?gcid=000089&ptid=17. Action Potential. ~1900 Julius Berstein suggested that nerve impulses were an electrochemical message created by the movement of ions through the nerve cell membrane.. Week 7. 1.

Is your model neuron able to receive input from the environment or other neurons?. Is your model neuron able to process the inputs it receives?. Objectives . Gain a general understanding of the nervous system. Gain knowledge of the structure and function of the neuron. Navigate your way around the major brain areas and understand their function. neuron. : a nerve cell; receives signals from other neurons or sensory organs, processes these signals, and sends signals to other neurons, muscles, or bodily organs. the basic unit of the nervous system.
