COGS 11 Lecture Notes - Lecture 6: Classical Conditioning, Habituation
Document Summary
Cb1 receptors affect major parts of the brain -> all affected by marijuana. Same substances can have different effects on the brain. Three types of implicit (procedural) learning ( we just know ): A form of learned fear/ need to be on a lookout. Any stimulus will sensitize you to noxious tones. Taking something beforehand that had no meaning and associating it with something with meaning. Action potential (will be on midterm 1) Neurons communicate from neuron to neuron from dendrites to terminal output. V (y-axis) is millivolts, time (x-axis) is msec. When sodium rushes in-> rise in action potential. When potassium gates open and potassium rushes out -> fall in action potential. Change in voltage -> opening of the sodium and potassium channels/gates. Between the time the sodium gate is open and blocked, is time-dependent. The time it takes to open/close is voltage-dependent. Potassium has a higher threshold than sodium channel, stays open longer than.
