Document Summary
Part 2 behavioural controls & information processing. Learning objectives: define / explain the significance of red terms, describe the role that genetics, the nervous system and hormones play in behaviour, differentiate between dispersal and migration. Describe different hypotheses to explain dispersal in animals. From a given example, be able to identify which potential hypothesis is at work: describe the two major issues facing long distance migrants. Identify the different types of compasses discussed in lecture and in your textbook. Differentiate between orientation and compass: from a given example, identify the potential cues that are being used to migrate. Adaptive behaviour depends on interactions between the nervous system, the body and the environment. Pathways: afferent ascending/toward the cns (usually sensory, efferent descending/away from the cns (usually motor) Receptor cell -> spinal cord -> brainstem -> higher brain areas. Higher brain regions -> brainstem -> periphery (effector) Feature detectors: specialized sensory receptors/groups of receptors that respond to important signals in the environment.
