Problem 7

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.

Step-by-Step Solution:
Step 1 of 3

Chapter Four Notes  Sensation and Perception o Sensation- what you take in from your eyes, hears, mouth, ect. o Perception- interpretation of data we sense o Illusion- when the stimuli does NOT match the perception  Sensation o All senses rely on same principles o External stimulus causes sense receptors located in the occipital lobe to pick up a neural activity and decide what to do about it o Transduction- process of turning what you sense into information your brain uses o Sensory adaptation  When its 50 degrees in winter and you go out without a coat because its “warm” outside  Ex- getting used to a bad smell to the point where you don’t even notice the smell anymore o Attention plays a key role as well  It is the amount of neural resources you give something o Selective attention- ability to drown out things that don’t matter (it’s a good thing) o Cocktail party effect  When you’re in a big room with lots of voices and you can still focus on the one person you are having a conversation with  But, when you hear something like your name, you focus your attention on that instead o Change blindness  Not noticing something in the background because you can’t pay attention to everything at once  The Vis
