In information by the organs. Ø Sensory

In orderto interact with the exterior world, our body uses different senses. We usuallytalk about 5 senses but recent studies count 21 senses in total.

A consensus wasreached within the scientific community. It specifies 9 principal senses includingthe five common ones.The sixthsense is equilibrioception. The perception of balance is controlled by thevestibular system. It represents cavities filled with a fluid and their interactionwith hair cells informs the brain on our movements. The equilibrioception isstrongly connected to the vision. Nonetheless, the absence of vision won’talter the equilibrium sense. Despite therestricted effect of the equilibrium, the seventh sense proprioception may stepin.

The spatial body awareness is the ability to determine exactly the localizationof each member of the body. It is considered as evident and people are usually unconsciousof its influence. Theprivation of equilibrium and / or proprioception may lead to dangerous situationssince the human won’t be fully aware of the way he evolves within this environment.these dangerous situations are reported as physical. This eighth sense is callednociception and represents the perception of nerve damage or tissue damage.The ninthsense is thermoception. It represents the ability to distinguish the heat from thecold through the skin and internal passages within the skin.All the senses are considered as perceptions are decryptedas sensory information by the organs.

Ø  Sensory information and Sensory integration Each sensory system of the bodysends some stimuli or sensory information to the brain. The sensory informationis transmitted to the brain through the nervous system. A structure of thebrain called thalamus receives the stimulus signals and relays them to theappropriate area in the cerebral cortex in order to be processed. In turn, the cortical areas (associationareas) send signals to the brain’s areas in order to combine information receivedfrom the multiple senses. This process is called Sensory integration. The laststep is left to the brain to interpret those signals and come up with aresponse.

        Ø  Sensesand MemorySensory systems interact withmemory in a few different ways. In order to provide the best appropriateresponse of a sensory stimuli, the brain may choose information from the memorythat has been stored previously. Hence, the sensory inputs that come from thecombination of different senses may be too much for the brain to process.

Therefore, sensory inputs are alsostored as part of a memory. It will represent the capacity to remember a place,or a smell, or even a painful action. It serves as a sensory processing areathat has been activated in the brain. Hence, the sensory inputs thatcome from the combination of different senses may be too much to much for thebrain to process.
