Then describe action potential and resting potential. What's different? What's the same? Anatomy- Neurons is always active or at rest- Resting Potentialo Electric charge against cell wall - Action potentialo Cell membrane opens and ions goes in- Neurons expend metabolic energy to create a chemical gradient.- Refractory period o Positive ions get pumped out. Get another ion to go action potential.- It contains 3 important positive ions.o Potassium o Calciumo Sodium- Neural activity creates distinctions in the neuron’s rate of firing.- Slow firingo A few action potentials in a second.o Many action potentials in a secondLecture 7 (Feb. 3rd) How does the food preferences related to inborn preferences and regional preferences? How dothey relate to each other? What is important about Alliesthesia? Food Preferences (Nutrition) - Inborno We want food consume felts and simple sugars- Regional o We want to eat food that taste like homeo Really spicy food takes longer to spoil- Hunger regulation cycle o Getting hungry- Alliesthesiao Helps us stop eating, food we love once we are stuff it makes the food not taste as amazing weight
