How do sensory neurons keep specificity between senses?

There are many different type of sensory receptors for telling different stimuli apart. So the ones that sense pressure on your skin are different from the ones that detect heat. Your retina has receptors for different wavelengths of light, your tongue has different receptors for different tastes, and so on. From there, information is transfered to afferent neurons which send the signal up to your brain. There is a labeled-line principle which basically states that each sensory neuron corresponds to a specific part of the brain. So when that area is stimulated, the brain "knows" what, where, intensity, etc.

My hunch is that with a bit more time separation between the stimuli, that the nerve cells would have time to recover between firing signals, and that they could build a greater action potential.  \n\nI'm a bit perplexed as to why you'd be tackling this problem at 7:30 AM on Thanksgiving Day......or are you in Europe?

Adaptations are hard-wired into our brains, and thus under some artificial manipulations can cause inappropriate interpretations of the visual scene. Or, as Purkinje put it: "Illusions of the senses tell us the truth about perception" (cited by Teuber, 1960).

I read about this.  It happens in bright light because the optical and nasal nerves are so close together.  The brain is receiving all these signals from both that are so close together that it can sort of trick itself.

dendrites are the extensions that pick up the signals.

There are specific neurons specialized for cold sensations- under hot water, there is ectopic activation of these neurons from the physical effects of heat on the synaptic membranes- These are then communicated through the spinal cord and mis-interpreted.

neurons are the sensors whish transmits the signal in the brain, so the statement sounds to be wrong

the nervous system is in the form of our five senses: touch/pain, vision, taste, smell, and hearing. Pain, temperature, and pressure are known as somatic senses. Sensory receptors are classified according to the type of energy they can detect and respond to.  \n\nMechanoreceptors: hearing and balance, stretching.  \nPhotoreceptors: light.  \nChemoreceptors: smell and taste mainly, as well as internal sensors in the digestive and circulatory systems.  \nThermoreceptors: changes in temperature.  \nElectroreceptors: detect electrical currents in the surrounding environment.  \n  I have a cite that has an abundance of information for you on this subject..hope this helps

Interesting. The brain is a bundle of neurons, but it has no "feeling" itself.  An electrode inserted into the brain is painless.

The tongue has receptors in it, that distinguish different molecules, which the brain interprets and records, and uses for reference later on. In conjunction with the tongue, the nose differentiates smells that coincide with tastes, and are also recorded somewhere in the brain. "Taste" is actually smell and taste, as interpreted and learned by our brain! :)

Lots of thing have more than the 5 senses we are used to. Bats and toothed whales use sonar, fish have lateral lines, sharks can pick up electro signals. Snakes and animals with whiskers can sense vibrations with their tounge and whiskers respectively.

Every new skill (and thought and emotion) tries to resolve itself against the patterns of your previous experience..  That is, if it is recognised as something familiar, then those linkages (neuronic connections) are reinforced.  Totally new information must create NEW linkages to your OLD information.  This process MUST be repeated (learning) or you will not remember the new information for long

try this link to make it clearer and to get a more scientific idea of it:\n\nhttp://en.wikipedia.org/wiki/Brain_mapping

Parts of our brain are used for senses. Touch, smell, taste, etc. They map which parts of the brain relate to which, and it makes psychologists and brain surgeons very excited. It's also how foreplay/non-conventional sex can be explained. See, our lips have one of the greatest surface areas on the physical sense brain map, meaning our lips are really sensitive. So are our, well, erogenous zones, genitals and such. So, we put the two sensitive organs together, and it makes everyone happy. Same explination for kissing.

I think it's hard to say because it's hard to define what "sense" means. The url below from wikipedia has a good, thorough explanation of the human senses. Hope this helps!

Simple: Our skin has sensory nerves =)

Millions of sensory receptors detect changes, called stimuli, which occur inside and outside the body. They monitor such things as temperature, light, and sound from the external environment. Inside the body, the internal environment, receptors detect variations in pressure, pH, carbon \ndioxide concentration, and the levels of various electrolytes. All of this gathered information is called sensory input. \nSensory input is converted into electrical signals called nerve impulses that are transmitted to the brain. There the signals are brought together to create sensations, to produce thoughts, or to add to memory; Decisions are made each moment based on the sensory input. This is integration. \n\nBased on the sensory input and integration, the nervous system responds by sending signals to muscles, causing them to contract, or to glands, causing them to produce secretions. Muscles and glands are called effectors because they cause an effect in response to directions from the nervous system.
