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 everyday experiences are?  Provide some examples of how perception is not foolproof. Discuss how perceptual sets can influence the way we perceive the world and provide an example of a time when your own perception of the world may have been influenced by past experiences and expectations.

ACCORDING TO: New Nerve Cell for the Adult Brain By: Gerd Kempermann and Fred Gage   What is the previous evidence that stem cells did exist in the adult brain? (This should be dated, with a brief explanation of the studies) How do we study neurogenesis in animals?  In humans? Where can we find stem cells in the brain?  What is so important about these brain structures?  (For example: Why do we find excess stem cells in these structures, but not in others?) How can stem cell proliferation be inhibited? How might neurogenesis be related to learning and memory?

In a nerve cell, the function of the myelin is to Group of answer choices 1. increase the speed at which nerve impulses are carried away from the cell body. 2. receive impulses and conduct them to the cell body. 3. support and nourish the neuron. 4. attach the neuron to connective tissue. 5. conduct impulses away from the cell body.

The membrane of a neuron is vital to its ability to respond to signals from other neurons. Which of the following statements about this membrane is NOT accurate It ensures that the interior of the cell has a slightly positive charge at rest. It is selectively permeable, allowing ions to move in and out of the cell. It contains different types of specialized protein ion channels. It is made of two layers of lipids (fat molecules)

Throughout this unit we have been learning about the nervous and muscular systems. Choose a disorder of one or both of these systems and discuss a disorder of them. Many disorders involve both systems.

Please provide approximately one paragraph b them discuss the following two questions about neurons. Question 1: Is there a relationship between the morphology (shape) and function of a neuron? Question 2: Many neurons differ in appearance due to the number of dendrites they have. What would be the advantage to a neuron to have multiple dendrites?

Describe the structure of a neuron and the function of each part. What are the differences between axons and dendrites?   comments : please give me answer with best of your knowdelge . Thanks

Describe how neurons communicate. To do this you must address: resting membrane potential; graded potentials; IPSPs; EPSPs; the role of sodium, potassium and calcium; generation of an action potential; inotropic vs metabutropic receptors; why is an AP only one direction; how are neurotransmitters released; continuous vs saltatory conduction; spatial vs temporal summation.

Which of the following is FALSE about action potentials?      At resting potential, there are more potassium channels open and most sodium channels are closed.     Depolarization is due to the flow of Na+ out of the axon via voltage-gated Na+ channels.     Hyperpolarization is due to continued loss of K+ from the axon.     During repolarization, K+ flows out of the axon along its concentration gradient.     Resting membrane potential is primarily established by the Na+/K+ pump.
