BIO 12 Lecture Notes - Lecture 15: Learning, Long-Term Memory, Procedural Memory
Document Summary
Stages of sleep: light sleep (1-2, smaller amplitude and faster rhythm, deep sleep (3-4, slow and large amplitude of neurons (delta rhythm) Basically awake and dreaming (similar to being awake and dreaming) Body is paralyzed during rem sleep (sleep atonia) = no body movement, just eye. Spinal motor neurons all hyperpolarized up to 10 mv by inhibitory reticulospinal movement system from pons. Cycle through the stages with a period of about 90 minutes. Different stages of sleep are distinguished by eeg. Learning to cope with a noisy apartment. Memory retention of information, skills, or thoughts. Automatic response: does not require a conscious effort. Hippocampus is involved (also affects the spatial) Rem and slow-wave sleep are especially important for the consolidation of. Information is first stored as short-term memory memories. Consolidation from short-term memory to long term memory = mechanism window. Ability to physically change over the life of the organism.
