PSYC 2240 Lecture Notes - Lecture 11: Substantia Nigra, Vomeronasal Organ, Calcitonin Gene-Related Peptide
Document Summary
The experience of one sense in response to stimulation of a different sense: an example would be seeing a number or a letter as a specific color, joined sensation. Tends to cluster in families that also have perfect pitch: genetic predisposition. Provide a very general description of pheromones and the vomeronasal organ. Pheromones: chemicals released by an animal to affect the behavior of others of the same species. Vno (vomeronasal) organ: is a set of receptors found in most mammals located near the olfactory receptors that are sensitive to pheromones: receptors are specific to one pheromone and does not habituate. Different type of receptors for different types of sensations. Describe the biological mechanisms, pathways and chemicals involved in the experience of pain the experience evokes by a harmful stimulus. Pain sensation begins with the least specialized of all receptors (bare nerve endings) some pain receptors also respond to acids, heat or cold.
