Explain the role of biology in the discipline of psychology. Describe how biological psychology helps us understand phenomena like love. Compare and contrast graded potentials versus all or none responses. Image sensed by your eye, triggered neurons. Neurons fired to visual cortex to perceive shapes. To association cortex to figure out what shapes are. Neurons fired to amygdala feel fear. Neurons fired to hypothalamus autonomic ns response increased heart rate . Neurons fired in prefrontal cortex controlled thoughts: wait a second, it"s only an image, calm down . Amygdala (limbic system), parts of prefrontal cortex. When viewing image of romantic partner while in pain, activation of neural reward systems and lower self-reported pain. If we want to understand people, we have to understand their biology, too. Activation of the cell body must meet a threshold to fire. Once threshold is reached, fires down whole axon (all or none) List and describe key points about major neurotransmitters.
