You can physically live without some senses (like smell, taste, or even sight/hearing with adaptations), but surviving without all five (sight, hearing, smell, taste, touch) from birth is virtually impossible for normal human development, as the brain needs sensory input to function and build consciousness, though specialized cases show extreme resilience, with touch being the most crucial for survival. A person lacking all senses would likely remain in a vegetative or extremely limited state, dependent on machines, as their mind wouldn't develop self-awareness, language, or complex thought.
Sensory loss can occur due to a minor nick or lesion on the spinal cord which creates a problem within the neurosystem. This can lead to loss of smell, taste, touch, sight, and hearing.
“People can live without vision or hearing, but there's no way to survive without touch,” Ginty said. “It's the sense that allows us to interact with the world directly, and it governs all aspects of our lives.”
Without any sense of a body (own or another's), with no vision and sound, without taste and smell - there will be no feedback. There will be no cause and effect. There will be barely nothing for the consciousness machine to develop beyond it's core survival properties.
According to the latest study, humans have a hidden "seventh sense" that allows us to detect objects without physically touching them. This so-called seventh sense is called "remote touch", similar to the sense used by shorebirds like sandpipers and plovers to find prey hidden beneath the sand.
Proprioception (body awareness)
The eighth, often neglected, but frequently problematic sensory system in SPD is the Interoceptive System. Interoception refers to sensations related to the physiological/physical condition of the body. Interoceptors are internal sensors that provide a sense of what our internal organs are feeling.
This sensory loss required months of intensive rehabilitation so Ian could learn to move his body and limbs again. Kim, on the other hand, was born without somatosensation. She does not possess the sensory nerve fibers necessary to feel her body, possessing neither the sense of touch nor proprioception.
Agnosia is a rare disorder whereby patients cannot recognize and identify objects, persons, or sounds using 1 or more of their senses despite otherwise normally functioning senses. Memory, attention, language problems, or unfamiliarity with the stimuli cannot explain the deficit.
You can likely name the five senses: sight, smell, sound, taste, and touch. But did you know humans actually have as many as 8, 21, or even 33 distinct senses? Researchers are still debating what constitutes a sense. However, we do know our senses are tied to almost everything we do.
How to Cope With Being Touch Starved
In rare cases where someone is born lacking proprioception, tasks like touching their nose without using their eyes or even walking with their eyes closed become impossible. A lack of proprioception can also impact how people experience force and the heaviness of objects.
Technically, you never touch anything. What you feel as touch is actually the electromagnetic repulsion between atoms in your skin and atoms in another object. The electrons push back before the atoms ever make contact. At the most fundamental level, everything you “touch” is held apart by invisible forces.
Research first to show humans have remote touch “seventh sense” like sandpipers. A study by researchers at Queen Mary University of London and University College London has found that humans have a form of remote touch, or the ability to sense objects without direct contact, a sense that some animals have.
8 ways to come back to your senses
While popular culture often refers to a "sixth sense" as something supernatural, in reality, we already know there are more than five senses: our sixth and seventh senses are balance and proprioception. So, the next time someone mentions their "sixth sense," you can enlighten them with this sensory knowledge!
Anosognosia is a condition where you can't recognize other health conditions or problems that you have. Experts commonly describe it as “denial of deficit” or “lack of insight.” It falls under the family of agnosias, all of which happen when your brain can't recognize or process what your senses tell it.
Agnosia is a rare disorder characterized by an inability to recognize and identify objects or persons.
Neurodegenerative brain diseases
They include Alzheimer's disease, Parkinson's disease and ALS (amyotrophic lateral sclerosis), among many others. They're most often slowly progressive and interfere with thought, memory, movement or some combination of these things.
Description. Channelopathy-associated congenital insensitivity to pain is a condition that inhibits the ability to perceive physical pain. From birth, affected individuals never feel pain in any part of their body when injured.
Otofacial syndrome is an extraordinarily rare congenital deformity in which a person is born without a mandible, and, consequently, without a chin. In nearly all cases, the child does not survive because they are unable to breathe and eat properly.
Deprivation can cause developmental deficiencies in babies. Studies have shown that in extreme cases, touch deprivation can lead to infant death. In adults and older children, touch deprivation is related to conditions such as depression, aggression, and eating disorders.
They are: Touch, Life, Self-Movement, Balance, Smell, Taste, Sight, Temperature/Warmth, Hearing, Language, Thought and Ego or the sense of the 'I'.
Easily identified and eminently useful is No. 13, the sense of equilibrium. Its most important receptors are three fluid-filled canals set in different dimensions in the labyrinth of the ear. This affords, says Foerster, “the ability to maintain balance even though our ears be plugged and our eyes closed . . .
Interoception is awareness of your body's internal senses or signals. It identifies how you feel. You can consciously or unconsciously respond to these signals. For example, if your stomach rumbles, you know you're hungry.
