requires the usage of ATP. When the membrane potential of a pre-synaptic neuron changes‚ due to different chemical and neurotransmitter stimuli‚ these ions are released depending on the level of potential happening. “When an action potential starts‚ the graded potential depolarizes the membrane to a point called threshold potential.”(BOOK) During depolarization‚ the neurotransmitter is release and opens sodium channels with allows sodium ions to move into the cell. This action triggers the opening

Session 9: The Nervous System - Assignment #2 PhysioEx Assignment : Exercise 3 Neurophysiology of Nerve Impulses Activity 1: The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Increasing the extracellular K+ causes the membrane potential to change to a less negative value because when K+ ions diffuse out across the membrane they are leaving behind a net negative charge. 2. Explain

#1 Make Observation What causes Alzheimer’s disease neurologically? This question came to my mind when I was watching the movie ‘The Notebook’ for the fifth time. Unusual for a guy‚ I love romantic genre movies and I was wondering why Alzheimer causes short and long term memory loss. I also had an interest on the Alzheimer’s disease after watching the movie ‘Rise of the Planet of the Apes’ where the protagonist tries to fix the neurology nerve system to heal his father’s Alzheimer. #2 Ask Question

When comparing the biological and psychoanalytic approach to psychology‚ you are able to see that they are different from one another. For example‚ the biological approach assumes that the mind and behaviour originate from the functioning of the body and that behaviour is driven by biological instincts. Whereas the psychoanalytic approach

The medication is a mixture of various salts of the two amphetamine stereoisomers and inactive ingredients; by salt content‚ the active ingredients are 75% dextroamphetamine salts and 25% levoamphetamine salts . Adderall works by increasing the activity of the neurotransmitters norepinephrine and dopamine in the brain‚ which results from its interactions with trace amine associated receptor 1 and vesicular monoamine transporter 2 . Adderall shares many chemical and
