PSYC1101 Lecture Notes - Lecture 10: Botulinum Toxin, Procedural Memory, Lateral Sulcus
Document Summary
Create sophisticated machines+tools cars, phones, robots, planes. Art, literature, music creativity ; don"t fulfil maslows hierarchy or what we need but what we like/appreciate. Create cities social structures w societal roles. Bipolar neurons = 2 main extensions. connect other neutrons unipolar neurons = 1 short extension, branches into 2, 1 becomes dendrite and 1 axon. motor neurons = send messages to muscles or glands. Glial cells = surround and support neurons. manufacture nutrients and remove toxins and wastes. At rest, the neutron is polarised due to the difference in charge. Neuron increases in positive charge as na+ ions flow in. (sodium channels open) Neuron decreases in charge after action potential as k+ flow out. (potassium channels open) Sodium potassium pump then actively restores the balance of na+ and k+ to their original locations in or out of the neutron. graded potentials = doesn"t reach threshold potential therefore no firing.
