We have considerably more than five senses, but the actually number is a matter of some dispute. We settled on 10 senses for this post, but some scientists go all the way up to 17; and this doesn’t include seeing dead people or having common sense!

We live in a world where our eyes and ears are almost constantly bombarded with colors, shapes, textures and noises of all types. How exactly do our brains translate these sights and sounds into meaningful images and words?

Researchers may have solved a piece of the puzzle surrounding how fish “smell” harm.
When one fish is injured, others nearby may dart, freeze, huddle, swim to the bottom or leap from the water. The other fish know that their school mate has been harmed. But how?

Not only is there a real connection between vision and other senses, but that connection is important to better understand the underlying mechanisms that can quickly trigger sensory changes, according to new research.

As we’ve already begun to discover from previous posts we don’t so much see as perceive. Our eyes and brain don’t function like a camera; light falling on our retina is only the beginning...

Our five senses–sight, hearing, touch, taste and smell–seem to operate independently, as five distinct modes of perceiving the world. In reality, however, they collaborate closely to enable the mind to better understand its surroundings. We can become aware of this collaboration under special circumstances. In some cases, a sense may covertly influence the one we think is dominant. When visual information clashes with that from sound, sensory crosstalk can cause what we see to alter what we hear.

We did not randomly feel the world, but that our brain created a special map that represented our skin surface. This map of the skin surface is in the same place in everyone’s brain, and is called the primary sensory cortex (or somatosensory cortex, see below).

Neuroscientists have discovered how the sense of touch is wired in the skin and nervous system. The new findings open new doors for understanding how the brain collects and processes information from hairy skin.

We don't see only what meets the eye. The visual system constantly takes in ambiguous stimuli, weighs its options, and decides what it perceives. This normally happens effortlessly.

In a new study scientists at NYU Langone Medical Center have shown that the sense of smell can be improved.

Neil Harbisson can only see shades of grey. So his prosthetic eyepiece, which he calls an “eyeborg”, interprets the colours for him and translates them into sound. Harbisson’s art sounds like a kind of inverse synaesthesia. But where synaesthetes experience numbers or letters as colours or even “taste” words, for example, Harbisson’s art is down to a precise transposition of colour into sound frequencies. As a result, he is able to create facial portraits purely out of sound, and he can tell you that the colour of Mozart’s music is mostly yellow. Liz Else caught up with him at the TEDGlobal conference.

Herbert and her team concluded: "'Interoceptive awareness' as assessed by heartbeat perception seems to represent a better ability to focus, to perceive and to process internal bodily information across visceral modalities, such as gastric signals, with cardiac and gastric signals both representing bodily cues that show perceivable activity changes during situations of everyday life."

There's no limit to the possibilities, and nature provides neuroscientists with a constant source of inspiration: "Snakes see in the infrared range and honey bees see in the ultravnstantiolet range. There's no reason why we can't start building devices to see that and feed it directly into our brains." NEUROSCIENCE: http://www.scoop.it/t/science-news?tag=neuroscience

Imagination is the ability to form mental images, phonological passages, analogies, or narratives of something that is not perceived through our senses. Imagination is a manifestation of our memory and enables us to scrutinize our past and construct hypothetical future scenarios that do not yet, but could exist. Imagination also gives us the ability to see things from other points of view and empathize with others.

Just like a road atlas faithfully maps real-word locations, our brain maps many aspects of our physical world: Sensory inputs from our fingers are mapped next to each other in the somatosensory cortex; the auditory system is organized by sound frequency; and the various tastes are signaled in different parts of the gustatory cortex.

“I have this rather freakish gift of seeing letters in color,” novelist Vladimir Nabokov told a BBC interviewer in 1962. “It’s called color hearing. Perhaps one in a thousand has that.” Articles about NEUROSCIENCE: http://www.scoop.it/t/science-news?page=7&tag=neuroscience

As neurologist V.S. Ramachandran writes in his book The Tell-Tale Brain,"Even though our picture of the world seems coherent and unified, it actually emerges from the activity those thirty (or more) different visual areas in the cortex, each of which mediates multiple subtle functions."

“If we think of the perceptual system as a democracy where each sense is like a person casting a vote and all votes are counted (albeit with different weights) to reach a decision, what our study shows is that the voters talk to one another and influence one another even before each casts a vote.”
