Watch this video (http://openstaxcollege.org/l/summation) to learn about summation. The process of converting electrical signals to chemical signals and back requires subtle changes that can result in transient increases or decreases in membrane voltage. To cause a lasting change in the target cell, multiple signals are usually added together, or summated. Does spatial summation have to happen all at once, or can the separate signals arrive on the postsynaptic neuron at slightly different times? Explain your answer.
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…
Neurotransmitters, the chemicals used in signaling across synapses, can be either re-absorbed by the pre-synaptic neuron OR hydrolyzed after release by enzymes. Acetylcholine (ACh), the neurotransmitter at neuromuscular junctions, is broken down by the enzyme acetylcholinesterase (AChE) and then its component parts are re-absorbed.
Sarin gas is an extremely dangerous neurotoxin that has been utilized in terrorism and chemical warfare. It is known as a "nerve gas" because it blocks AChE. Based on your understanding of the neuromuscular junction and hydrolitic enzymes, hypothesize how sarin gas le

- Using your knowledge of the central nervous system and various cell-cell interactions, identify the key type(s) of cell junctions in the human cerebral cortex tissue. Briefly describe the function of these cell junctions. How would the function of the central nervous system be impaired if your above identified cell junctions were disrupted?arrow_forwardWhich statement is TRUE about the synapse? Neurotransmitters shuttle the signal back and forth between the pre- and post-synaptic cell. The pre-synaptic cell and post-synaptic cell are in direct contact, allowing the electrical signal to seamlessly flow from one to the other. The action potential jumps from the pre-synaptic cell into the post-synaptic cell. The action potential ends in the pre-synaptic cell and neurotransmitters carry the signal across the synaptic cleft to the post-synaptic cell.arrow_forwardWhat adaptive advantage do synapses provide in nervoussystems (i.e., why isn’t the nervous system just a mesh of cellscytoplasmically connected through gap junctions)?arrow_forward

- Which of the following statements is not true about neurons? When there is no active nerve impulse, the concentration of Na+ ions outside of the cell is greater than inside the cell After a nerve impulse passes a region of the axon, that region will not be able to carry another impulse again for a brief period of time When a nerve impulse occurs, sodium channels in the axon open first, followed by potassium channels The inside of an axon is typically negatively charged compared to the outside of an axon The cell uses energy to actively pump Na+ ions into the axon and K+ ions out of the axon.arrow_forwardHow would nervous system function be affected if both the presynaptic and postsynaptic neurons at every synapse had both synaptic vesicles and neurotransmitter receptors?arrow_forwardWhich of the following statements is FALSE? (Choose the best answer) O Neurons in the nervous system use electrical and chemical synapses to communicate between neurons and their target cells. Chemical synapses allow presynaptic neurons to excite or inhibit the postsynaptic neurons. O Electrical synapses allow presynaptic neurons to excite or inhibit the postsynaptic neurons. O Electrical synapses allow direct exchanges of both electric current and cytoplasmic contents.
