NROC64H3 Chapter Notes - Chapter 9: Indirect Pathway Of Movement, Receptive Field, Neurotransmitter Receptor
Document Summary
Sensitivity to light enables animals, including humans to detect prey, predators, and mates. Due to bouncing of light in eyes from objects around us in order to make sense of complex object light is an electromagnetic property that is emitted in the form of a wave. Due to nature of electromagnetic waves and interaction with the environment, the visual system can extract information about the world. Vision is provided new ways to communicate, give brain mechanisms for preparing for trajectory of objects and space and time allowed for new forms of mental imagery and abstract. Half of human cerebral is involved in analyzing the visual world. Mammalian visual system begins with eye at the back of the eye is the retina: contains photoreceptors specialized to convert light energy into neural activity. Eye automatically adjusts to differences in illumination and automatically fixates on objects of interest. Eye can track moving objects (by movement) and keep its transparent surfaces clean (by blinking)
