Second half of the material Lecture 1 Common mistakes on the short answer questions Aggression via sociobiological theory Evolutionary theory and survival ability to reproduce and keep your genes alive In case they are being tested by other people More aggressive would be able to mate Factors that influence schema accessibility types of priming Frequency of access chronically accessibility Emotional significance Primacy recency of access Successive Approximations Discussion class training game test things out reinforce behaviors that start to approximate Primary reinforcers v Secondary reinforcers punishers Primary natural in born food born wanting food Secondary have to learn that this is reinforcing Representative Heuristics Stereotypes Shortcut to make a decision Using information that goes along with a stereotype to make a decision Neurons cells that make up the parts of the body Parts of the Neuron A soma B dendrites C axon hillock connects axon to dendrites D Axon signal AP sends signals to terminal E myelin sheadths schwann cells F terminals G terminal buttons Inside the soma you have a resting potential 70mv Getting signals that are telling you that you need to open up the gates that allow for the ions to get inside electrical charge becomes more positive As you get more excitatory you hit the threshold and once you hit the threshold then you want to send an action potiential the electricity spikes then goes back down see graph o Whats going on with ions happens initially in the ssoma Ions coming in from outside of the axon cell hit the threshold send an AP allowing for more ion channels to open electrical wave electrical impulse changes for a second and then goes back out again allowed to send the signal down the wave Ions when they go in then they get spitted backed out just changing the electrical charge Absolute refractory signal downhill slow no matter what happens to the cell it cannot send a signal down again even if that means that ions are coming into the cell Relative refractory period the little dip rigt there you need more of ion charge to reach the threshold period to generate an action potential you can have another action potential but its going to require more excitatory stimulus than normal What happens when the ions get to the terminal Occurs at the synapse don t actually touch each other there is a gap which is called the synaptic cleft The synapse is the overall section between the terminal and the dendrite Inside the terminal button there are vesicles that hold Ach o Send signal to the vesicles saying release your transmitters keys into the space synaptic cleft o Ach attach to the receptors site keyholes receptor tells cells to open up some ion channels o Some receptors say open ion channels excitatory other say close the ion channels inhibitory o Neurotransmitters goes back into the vesicle that he came from called reuptake
