We made a list the day we did the activity on autism and memorization - trial and error, association with something we already know, emotional responses(silly mnemonics, girlfriend), being able to pick out the wrong answers,etc.
pages 214-216 When an action potential occurs in one area of the axon the electrical disruption stimulates the neighboring areas to meet threshold. Then "impulse" travels down the axon in a wave like motion. Steps to action potential are 1. polarized - cell is at rest, more sodium outside the neuron, more potassium inside the neuron 2. depolarization - sodium rushes into the cell because of a stimulus 3. re-polarization - potassium rushes out of the cell to make the inside of the cell more negative again -. Then the sodium/potassium pump works to move sodium back out and potassium back in so the resting potential #'s inside the cell quickly return to normal.

ReplyDeletehow and why do we learn / memorize

DeleteStill confused on how a nerve impulse is generated

DeleteGood table - 9.1 top of page 216
