Your olfactory and gustatory systems in action.

I Simply

I simply wanted to take a look at you and when I saw you something happened to me. My reasoning became like dust particles easily blown by the wind and my judgement became like a fish that had forgotten how to swim. The loveliness of your face and figure caused me to lose my equilibrium. I felt as light as a snow crystal. All I wanted to do was to see what you looked like without the thought…

The Visual System Explained

What is the Visual System?

The visual system is the part of our sensory system that is responsible for our sense of sight. This complex system starts a journey with light waves that enter your eyes, then a chemical signal is sent to the primary visual cortex-this is located in the occipital lobe of the brain. Once there, the signal is then processed and converted into images we see and perceive.

The issues with the visual sensory system referred to below have nothing to do with sight damage or other ophthalmic disorders. If you are concerned your child has visual processing issues, the first step is to get their eyesight evaluated to rule out the need for glasses or other interventions.

The Visual Sensory System is responsible for:

1.) visual processing and visual perception,

2.) eye movement control

3.) color, shape, light brightness and contrast, and movement.

The visual sensory system is extremely important for information gathering and learning. Visual sensory disorders can be the culprit behind struggles in school, speech and language difficulties and learning disabilities.

The visual and vestibular systems play an important role when working with and teaching children. Remember, you can always request your school district give your child an occupational therapy evaluation. Working with a qualified occupational therapist in the school setting can help the child improve their visual processing skills and learning abilities in school activities.

A Healthy Visual System

Vision works closely with all of the other senses in our sensory system. As children, when we see a dinner our mom made, we realize we are hungry because the sight of the food made us more aware of the smell of the food (olfactory system) and our mouths may have began to water imagining the taste (gustatory system)! Or if you are walking to the car alone late at night and you see a shadow of someone walking up behind you, you become aware of your surroundings and may develop goosebumps that developed from our tactile system.

Problems With Visual Processing

Even a unproblematic visual system works in a very intricate and complicated matter. There 8 subtypes of visual processing disorder and they can appear in any combination or independently.

Subtypes of Visual Processing

1.) Visual Discrimination

2.) Visual Memory, long and short term

3.) Visual Motor Processing

4.) Visual Sequential Memory

5.) Visual Spatial Processing

6.) Visual Figure Ground

7.) Visual Form Constancy

8.) Visual Closure

Listed below are signs that your student may be having issues with their visual processing skills. I’ve specifically chose to add things you’d observe in a school setting. However, this is no where near an exhaustive list of symptoms since everyone has a unique set of circumstances and may present differently from one person to the next.

Characteristics of Malfunctioning Visual Processing In School Environments:

* Difficulty with sports and physical education

* Falling asleep in class or struggling to sit still in class

* Squints or develops headaches from reading or copying from the board

* Nausea when trying to read or do homework in the car

* Poor math skills

* May complain of pain in eyes

* Difficulty memorizing spelling words,

* May struggle to retain or recall what they have read or watched

* Work performance is disorganized

* Difficulty with writing eye-hand coordination skills like letter spacing, letter reversal or out of order, or copying, sloppy writing for their current grade level when compared to peers.

* May show difficulty completing puzzles

* Unable to judge distances accurately, this can be displayed as bumping into things easily or trouble pouring liquids

* Difficulty with fine motor skills such as cutting, art work, tracing, etc.

Children showing signs that they are having difficulty processing visual information can exhibit a hypersensitivity or hyposensitivity. Hypersensitivity means the sensory system is over reacting to visual stimuli it’s taking in. Hypo-sensitive is when the sensory system is under reacting to he visual stimuli it’s taking in. They may present with some of the following characteristics.

Hypersensitive 

* Aversion to bright lights or colors

* Avoids eye contact

* Reoccurring nausea and headaches after reading or computer activities

* Frequently covers eyes

* Bumps into things

* Highly overwhelmed,easily anxious or other emotional behaviors

* Avoids group play activities

* Avoids crowds

Hyposensitive

* Spaces out

* Stares at objects or light

* Looks unusually close at objects, or out of the side of their eyes

* Enjoys bright colors

* Engages in excessive movement when reading or doing schoolwork, self soothing by increasing their vestibular stimulation

Home Based Activities To Help With Visual System Differences:

* If struggling with headaches or eye pain, limit reading and time spent watching TV at night

* Keep areas clear of clutter

* Choose either calming or stimulating colors, based on desired response from child

* Choose natural light when possible and avoid fluorescent lighting

* Encourage your child to stimulate their vestibular system by engaging in activities such as rocking, swinging, hanging upside down, etc.

* Encourage your child’s proper posture during all activities

* Help ensure your child is understanding, comprehending and retaining the learning materials

* Use large lettering

* Play fun physical games with your child like homemade obstacle courses, scavenger hunts, hide and seek, etc

* Other fun activities for you to do with your child include building a model using Lego’s, cooking with instructions, tracing, origami, etc

Advice To Caregivers:

As mentioned above, ruling out vision loss or damage is the first step before addressing any visual processing related to the sensory system. The next logical step is an occupational therapist to help you come up with case specific activities you can do with your child to best support them. When doing the activities with your child, keep it light and fun. If it loses its fun factor the child won’t want to participate and even if they still do, progress will likely stop.

Somatosensation (the sixth sense)

The body functions and interacts with its surrounding environment through the simultaneous inputs of our five senses; gustation (taste), ocular (vision), olfaction (smell), vestibular (balance) and auditory (hearing), respectively. However, it is often forgotten that we also have a "sixth sense", understood to be our sense of somatosensation. Somatosensation is an overarching sense which includes the sub-modalities of:

Thermoception (temperature);

Nociception (pain);

Equilibrioception (balance);

Mechanoreception (vibration, discriminatory touch and pressure);

Proprioception (positioning and movement).

Collectively, these senses allow us to participate in our activities of daily living (ADLs) by guiding our movements, all the while minimizing the possibility of sustaining an injury.

Sensory System

The life of a neuron begins in the developing embryo, starting with the formation of the neural tube. The neural tube is the embryonic structure that will ultimately make up the brain and spinal cord.

[neurosciencesensoryunit]

The Neuroscience Sensory Unit consists of students who study and analyze neuroscience literature. The students work on publications that serve to explain complicated neuroscience processes, making current literature more understandable.
