List and describe the two types of cells found in the nervous system. Discuss, in detail, how neurons communicate with each other, including the role of neurotransmitters. Include a description of how different neurotransmitters mediate behaviors and cognitive processes. Watch this Sandrine Thuret’s “You can grow new brain cells. Here’s how” and Sebastian Seung’s “I am my connectome” and summarize, in detail, the main points. Discuss what each video tells us about the function of neurons in creating our thoughts and behaviors. What do you personally think are the most important ideas from each video? Why?
Define the terms sensation and perception. Watch the “Do we see reality as it is?” and “Your brain hallucinates your conscious reality” videos and describe the main points of each video in detail. Discuss what the textbook says about how the brain constructs our perceptions of the world. With the information from the videos and textbook, how accurate or “real” do you think our…

- Use what you know about the physiology of neurons to answer the following questions. Treat questions a- c as unrelated to each other. a. Imagine that a toxin creates pores in a neuron that are permeable to Na*. Describe its immediate effect on the resting potential: identify which ions diffuse across the membrane, which direction they diffuse (and why), and whether this brings the neuron closer to or further from its threshold potential. b. Imagine that a toxin makes K* leak channels more permeable to K* ions. Describe its immediate effect on the resting potential: identify which ions diffuse across the membrane, which direction they diffuse (and why), and whether this depolarizes or hyperpolarizes the neuron. c. Imagine that in a different neuron, voltage-gated K" channels open quickly, only 0.3ms after voltage-gated Na channels.
