PSYC 306 Lecture Notes - Lecture 99: Mantis Shrimp, Sensory System, Color Blindness
Document Summary
Be able to briefly define what each type of sensory receptor does. Understand the importance of auditory mechanoreceptors in moths. Learn the importance of bats usvs and how they search for moths. Understand the role of a1 and a2 mechanoreceptors in moths l. Animals acquire environmental information from their sensory system. We can detect light, chemicals with taste, vibrations through skin, detect heat to certain extent, magnetic field. Different sensory receptors can detect chemicals, light, vibrations, heat, electric fields, or magnetic fields. Nerve endings that respond to environmental stimuli+ transmit information via neurons. Respond to endogenous (comes from within our body) or exogenous (comes from outside the body) chemical signals. Translate into biological signal (brain can act or not) Nerve endings (dendrite) from nerves + search for chemical signals. Translate these signals in environment into biological signal (neural)--> brain can process and act on it if it needs to. Detect light--> convert into protein system (cause action potential or not)
