Document Summary
Learning: types of learning, using invertebrates to study learning, classical conditioning in vertebrates. Memory: types of memory, brain mechanisms in memory, effects of stress and aging. A relatively permanent change in behavior due to experience. Types of learning: associative and nonassociative learning, habituation and sensitization. Types of nonassociative learning that do not involve forming a connection between two elements or events: classical conditioning. Is a type of associative learning that does involve forming a connection between two elements or events. Habituation occurs when an organism reduces its response to a repeated stimulus. Often habituation occurs to unchanging, harmless stimuli as a means of focusing our attention on relevant stimuli: an example is when you do not notice trucks and cars driving by outside while you are studying. Using invertebrates to study learning (very simple neural network: sea slug aplysia californica, habituation in aplysia. Reduced activity at synapse between sensory and motor neurons: sensitization in aplysia.
