Document Summary
Lec 1: revisiting the basic principles of learning. Types of learning and responses: reflexes and modal action patterns (not learned, habituation and sensitization, classical conditioning, operant conditioning. Reflex is a relatively simple, automatic response to a stimulus. Can range from a very simple reflex (involving one system/relationship), to complex reflexes (involving multiple systems/relationships) Neural organization of a simple reflex can consist of only 3-neurons! Reflexes are adaptive, contribute to an animal"s well-being or survival: eye blink reflex, gag reflex, head turning in infants. Knee-jerk reflex depends on sense organs in the patellar tendon just below the knee-cap and on the quadriceps muscle in the upper leg. Though close, these are not simply connected to one another. The sensory nerve travels up to the spinal cord in the rump region and there synapses with the motor nerve which passes back down to the leg to the muscle. The scratch reflex of a dog as studied by sherrington.
