### module | sense:

Vision
* Includes people with partial or no sight.
* Most vision helps animals.
* Some vision helps primates.
* affects mushroom bodies and central complex in Drosophila melanogaster.
* also means having the acuity to see the future through the past.
* are understandings, ideas and illusions
  - where dreams come from illuminating our minds for both better and worse
* becomes worse when the sufferer is tired, under stress, in strange surroundings, etc.
* begins by gathering information through the senses about what currently is
  - with sight
* can be blurry for several weeks or months until it stabilizes.
* can become conscious suddenly and dramatically, or it can unfold slowly
  - severely impaired, with central vision rather than peripheral vision affected
  - change as people proceed, as their horizons broaden, and as new discoveries are made
  - coordinate with hearing, but mostly through the emotional center paths
  - deteriorate during the childhood years
  - often be the basis for poor eye-hand coordination, motion sickness and clumsiness
  - range from near normal to very poor depending on the number of inflammed nerve fibers
  - vary from good, to guarded, to blind
* comes into play only at close quarters, during conflict or to detect movement nearby.
* complex sensorimotor system.
* controls behaviour in livestock.
* depends on light, either from the sun or from an artificial source such as a light bulb
  - the transduction and decoding of electromagnetic stimulus energies
* deteriorates rapidly with age.
* different process than sight.
* diurnal bird of prey's most important sense for hunting and reacting to danger.
* frequently used sensing modality for a robot.
* fundamental factor in the learning process.
* goes beyond eyesight and can best be the understanding of what is seen.
* great motivator for young infants.
* have a disconcerting tendency to blind the visionary's conception of reality.
* health benefit that people actually enjoy using.
  - infants to learn and to develop
* involves detecting and focusing light from people and objects
  - light sensing while photosynthesis involves light energy conversion
  - the nervous system, brain, eyes and body
* is acute during daylight, but at night, it even rivals dogs and owls
  - alert and relaxed, or eyes are closed
  - also a linguistic procedure, a process of description, differentiation
* is an athlete's guiding sense
  - experience of reality through the medium of sight, therefore it is very tangible
  - important adaptation in higher vertebrates
* is an important part of communication
  - arguably the most important of the five senses
  - bands
* is blurred at best without focus
  - because the retina no longer has enough blood supply to function properly
* is blurred if the cornea, lens, and eye length place the image in front or behind the retina
  - lens is dislocated out of the line of vision
  - or lost in either eye
  - by far the most flexible sensory modality for sensing of the environment
  - capable of further plans
  - clarity of thought
  - combined with somatosensory information to give a sense of where one's body is in space
  - controlled by groups of cells called nuclei in the brainstem
* is corrected by reshaping the eye
  - inner corneal bed of the eye
  - dependent upon photosensitive pigments found in the outer segments of rods and cones
  - diminished because of mucus adhering to the contact lens
  - distal, and pictures are visual, because pictures show what is distal
  - disturbed after a blow to the eye area
  - examined by recording how accurately the eyes can follow a moving light
  - gener- ally more highly developed than in other mammals, the sense of smell less so
  - imagination
  - in the eye of the beholder
  - inward seeing, much like prophecy but rather than being auditory or written, it's visual
  - lost in the center of the visual field, which makes reading especially difficult
  - made possible by light reflection within the eyes
  - mediated by the specialized structures and visual receptors in the eye
* is more important to the chameleon than their sense of smell
  - than the limited concept of sight measured in terms of visual acuity
* is often the first sense affected by aging
  - most important sense for a predator
  - one of our most precious senses
* is one of the most important factors related to learning activities and abilities
  - sensory systems in birds
* is one of the primary sensory modalities for concept development in infants
  - substrates for mediating interaction with the physical world
  - our ability to see
  - preserved in stories, symbols, mental images, and documents
  - probably the most powerful of the body s senses and primarily used in imagery
  - renewal, part of the process of human life
  - responsible for giving accurate information about one's surroundings
  - so much more than what's measured in terms of visual acuity and the health of the eyes
  - stimulated from the very beginning, as are all the other senses
* is the ability to focus on and comprehend that which is seen
  - get meaning and understanding from what is seen by the eyes
  - imagine what's beyond the horizon and make it real
* is the ability to make meaning and interpret the information coming through the eyes
  - sense out of what one sees
  - see ahead
* is the ability to see the future potential of a product, technology, or market
  - opportunity within the current circumstances
* is the art of seeing invisible things
  - the invisible
  - things invisible
  - capacity to see possibilities
  - criteria that separates a leader from simply a manager
  - definition of a long-term goal
  - deriving of meaning and direction of action as triggered by light
  - fundamental force that drives everything else in our lives
  - highest order product of the brain, dependent on the precise teaming of both eyes
  - least mature sensory capacity
* is the most important means of communication and foraging for many ray-finned fishes
  - sensory input for birds, as they are visual animals
  - source of sensory information
  - operating system of the brain
  - perfume of the mind
* is the primary motivation of human action
  - sense used to hold their place in a school
  - process of deriving meaning from what is seen
  - quiet intelligence behind sight
  - reciprocal action between the eyes and the brain
  - strongest of human senses
  - threatened when the inflamed arteries obstruct blood flow to the eyes and optic nerves
  - used in control of the horse
  - usually impaired but total blindness is very uncommon
  - very good for dolphins, and they have the ability to see both in the water and out of it
  - well developed in most snakes, but many burrowing snakes are virtually blind
* is what drives success and accomplishment
  - moves people forward
  - where the spark resides
* learned process
  - skill, just like learning to walk or to talk
* mental picture of a desirable future.
* needs to have the work of both the eyes and the brain to process any information.
* occurs mainly in the brain.
* often die when they try to be all things to all people.
* plays a big role in communication.
* plays an important role in the behaviour of blackflies
  - orientation of individuals within a school
  - survival of organisms moving around in our environment
  - minor roles
  - primary roles
* power of the soul and spirit so that no eye sees the same.
* provide a sense of hope, and hope is the ultimate human fuel of change.
* reduces the risk created by uncertainty.
* relates to dreams and goals of what is possible and desirable to do
  - with liver meridian
* requires a functioning eye and light.
* sign of hope.
* social practice that is rooted in the whole of being.
* starts when a particular task has to be performed.
* tends to improve until it stabilises around the age of five or six.
* usually becomes more and more impaired until, finally, irreversible blindness sets in.
* varies with species and auditory sensitivity is usually sharp.
* very important sense in the developing infant.
* whole brain process.
