Document Summary

Can be caused by brain issues or external causes. Brain areas associated with the sleep cycle. Reticular formation of midbrain, pons, and medulla. Some species" brains sleep one hemisphere at a time (dolphins) One nostril is more open than the other. Hemispheric switching of eeg activation: 90 minute cycle. Same cycle: right nostril open, the left hemisphere is more desynchronized. You do better with these skills as hemispheres switch. Sensory chapter: detecting and discriminating between different types and levels of energy. British empiricists (like hume and locke) believed: the world comes to us through senses. Nativists: agrees that much of our knowledge comes from senses , but some knowledge is given to us through our genes. Types of energy that humans can sense/detects. Stimulus: intensity and quality of the physical energy. Wavelength: 450-700 can be perceived by people. Psychophysics: physical qualities of energy and psychological aspects that are stimulated. Sensitivity: how low of energy you can detect.
