Document Summary

General principles of senses: how brains gain info from the world/ how to act upon senses. General principle 1: all senses require transduction of info from the world into neural signals. Function of sensory systems: detect and process info about the physical world. 5 different types of info transduce into neural signals = 5 senses (through eye, ear, skin, nose, tongue) Senses that human have are only found in a fraction of all the senses of the world. Echolocation: organs that can emit soundwaves that bounce off and get reflected back where they can process it. Magnetoreceptor: can detect how far the bird is oriented from north to south because of magnetic field. Humans can only detect light in the visible light spectrum. Electroreception: sensitive to electrical fields to sense things in the environment (avoid obstacles) Vision: if we have an image in the world, it gets projected onto the retina.
