Vision
| Question | Answer |
|---|---|
| What is Sensation? | The conversion of energy from the environment into a pattern of responses by that nervous system |
| What is Perception? | The interpretation of that information |
| What is light composed of? | Pulses of electromagnetic energy that vary in both wavelength and amplitude |
| What is the amplitude of the electromagnetic wave? | It determines the intensity (brightness) of the light |
| What is the wavelength of the light pulse? | It determines the hue (color) of the light wave |
| What are the frequency ranges of the human eye? | Light comes in a variety of wavelengths, humans have specialized receptors that allow them to detect light on a dance of 350 to 700 nanometers |
| How do these cells work for vision? | In the back of our eyes, we have very specific cells that convert electromagnetic energy from light into a recognizable pattern |
| What is the structure of the eye made up of? | The pupil, iris, lens, cornea, blind sport, retina, fovea, and optic nerve |
| The pupil | A small adjustable opening in the eye, through whack light enters |
| The Iris | A colored adjustable muscle on the surface of the eye that is responsible for controlling the amount of light that enters the eye through the pupil |
| The cornea | A rigid, protective surface on the eye that focuses light toward the fovea |
| The Lens | A clear, flexible structure located behind the cornea that can vary in thickness (to help us focus on information at different depths), and focuses the incoming light rays into an image on the back of our eyes |
| The Retina | The multilayered tissue located on the back of the eye that is responsible for the transference of light rays into neural information |
| The Fovea | The central area of the retina that is highly adapted for detailed vision |
| Rods | Receptions that are adapted for vision in dim light and their primary purpose is to detect motion |
| Cones | Receptors adapted for color vision, daytime vision, and detailed vision |
| The optic nerve | A collection of cells that is responsible for carrying the information processed by your eye to the brain |
| What is the path of vision (after the eye)? | From retina goes through option nerve where optic chasm and optic tract combines and goes to the visual area of the thalamus which then sends the information to the visual cortex |
| What happens when the information from the eyes get to the brain? | Our areas for vision are arranged very intricately throughout the occipital lobe and beyond |
