MAIN SENSORY INPUTS
We express ourselves internally & externally from the VAKOG forms of gathering knowledge & understanding:
1. Visual – SEEING // 2. Auditory – HEARING  // 3a/b. Kinesthetic/Tactile – SENSING/TOUCHING // 4. Olfactory – SMELLING // 5. Gustatory – TASTING
Only the first 3 are widely used as major input channels for collecting data about our surroundings. 1, 2, 4 & 5 are obvious. #3a refers to whole body experiences involving sensations, emotions & motion itself. #b refers to learning by touch – such as the blind reading in Braille.

Summary of stimulus-to-response pathwayssensory process

Everyone uses all sensory channels to some degree, but the most valued ones are those we use on a regular basis – from birth – to bring information into conscious. While we all have the same basic brain structures, how these parts work can vary greatly between people – the way one person sleeps better on their side, while another does better on their stomach.

As adults, figuring out what our brain prefers will help us improve learning & memorization (when needed). Of course this is more complicated than noting our favorite sleep position. But if we diligently pay attention to how our brain ‘likes’ receiving information & in what form, that knowledge will help us understand our world better & make more sense of what we experience.

OTHERS (equally important sources of internal/external info) : senses circle
Chemo-receptors:  These trigger an area of the medulla in the brain that is involved in detecting blood-born hormones & drugs. It’s also involved in the vomiting reflex
Equilibrio-ception: This allows us to keep our balance & the sense of physical movements – of acceleration & directional changes. It also gives us a sense of gravity. It’s located in the inner ear, called the Vestibular Labyrinthine system. When malfunctioning, we can’t tell up from down, so moving from place to place without help is nearly impossible
Hunger: This system allows the body to detect when we need to eat

Itch:  Surprisingly, this is a distinct sensor system, a part of other touch-related senses
Magneto-ception: This gives us the ability to detect magnetic fields, mainly useful in providing a sense of direction, based on Earth’s magnetic field.  Unlike most birds, humans don’t have a strong magento-ception, but experiments show that we do tend to have some sense of it.  The mechanism for this is not completely understood, but it’s theorized that it has something to do with deposits of ferric iron in our nose. If that’s correct it would make sense, since humans given magnetic implants have been shown to have a much stronger magneto-ception than those without

Noci-ception:  In other words – pain. It was once thought to simply be caused by overloading other senses such as Touch, Actually it is its own unique sensory system.  There are 3 distinct kinds of pain receptors: cutaneous (skin), somatic (bones and joints) & visceral (body organs)
Pressure: Identifying shapes, softness, textures, vibrations….
Proprio-ception: Gives the ability to tell where our body parts are, relative to other parts. It’s one of the things police test when they pull someone over they think is driving drunk, as when they say: “Close your eyes & touch your nose”.  This sense is used regularly in small ways, such as scratching an itch somewhere on the body without having to see where the hand needs to goear structure

Sound: Detecting vibrations along some medium, such as air or water, that’s in contact with the ear drum
Stretch Receptors: These are found in such places as the lungs, bladder, stomach & the gastro-intestinal tract. One type of stretch receptor, which senses dilation of blood vessels, is often involved in headaches
Tension Sensors: These are found in such places as the muscles, allowing the brain to monitor muscle tension
Thirst: This system more or less allows the body to monitor its hydration level so the body knows when we need to drink

Thermo-ception: The ability to sense heat & cold, also considered a combo of senses.  This is not just because of the 2 hot/cold receptors, but because there’s a completely different type of thermo-ceptor in the brain, used for monitoring internal body temperature.
Time:  This one is debated, since no single mechanism has been found that allows people to perceive time. However, experimental data has conclusively shown that people have a startling accurate sense of time, particularly when younger. What we use for this seems to some combination of the cerebral cortex, cerebellum & the basal ganglia.
— Long-term time-keeping seems to be monitored by the supra-chiasmatic nuclei which are responsible for the circadian rhythm
— Short term time-keeping is handled by other cell systems

HIDDEN Senses – They automatically, unconsciously help to:
• control bodily functions, such as temperature & bladder fullness
• control timing & movement of food through the body (digestion)
• measure the amount of sugar & salt in the blood
• regulate the amount of oxygen that’s taken in, for breathing…..synesthesia

SYNESTHESIA – when 2 or more senses combine / overlap, such as seeing numbers in color, tasting words…. It’s hereditary and is estimated to occurs in 1 out of 1000 individuals, with variations of type and intensity.
