Study Points to Sixth Sense in Humans

Ben Sullivan writes "St. Louis researchers say there's something to the notion of a 'sixth sense' in humans. A part of the brain known as the cingulate cortex, they've found, likely combines multiple, sometimes unconscious data streams to come to conclusions and send warning signals to the conscious mind. Example: Aboriginal tribesmen somehow sensed the impending danger of December's tsunami in time to flee to higher ground before the first sign of water."

      Yeah, the whole "five senses" thing is crap from ancient greek philosophy. It's more accurate than their "four elements", but it's still not correct. There are numerous other senses. Balance (as you mentioned), sensed by the motion of fluid in the inner ear; proprioception/kinesthesia (as another poster mentioned), sensing body position; There are several "internal" senses-- hunger, full bladder, etc.-- as well. Basically, anything that your nervous system consciously registers (internal or external) is a sense. Technically, that tingling feeling you get just before a lightning strike during a thunder storm could be called your "sense of lightning".

    Calling this a "sixth sense" is very misleading. The normal five senses - sight, hearing, touch, taste, and smell, for those few who don't already know - involve the intake of information through specialized organs or tissues (eyes, ears, skin, etc.) in addition to the processing of those stimuli. This so-called "sixth sense" is simply the subconscious reprocessing of the same information obtained by the regular five senses (and that description misses the real point of the discovery anyway*), and so it hardly qualifies as a sense.

    Well, gravity detection and rotational motion detection are more commonly called the vestibular system. We have 5 organs dedicated to vestibular detection (other animals can have a couple more). Two of them are linear accelerometers (an inertial weight (calcium crystals + sticky stuff) on inner ear hair cells) that detect gravity, and linear motion of the head. Three of them are rotational accelerometers and are oriented to detect the three ways you can rotate your head. These are fluid filled tubes (semicircular canals) where the fluid acts as the inertial substance that rushes by the sensory hair cells when you rotate your head (and when you stop spinning around, the fluid keeps going making you feel dizzy). While these are all grouped together as vestibular, the outputs are not completely the same. For example, some of the output of the rotational detectors (technically, ampullae) goes directly to a reflex of your eye muscles to keep your gaze stable while you rotate your head. (As a demo of this, take a piece of paper and try to read it while you move it around quickly. You can't. Now hold the paper still but move your head around at the same rate. Your gaze is held stable while you move your head. Similarly, when you spin around in circles as a kid and stop, the world continues to spin (that is, your eyes continue to move as if you were still spinning as the fluid in the canals is moving but your head is not)). In fact the sensory cells that underlie this are virtually identical to the cells responsible for your auditory input (and for fish to detect water flow or electrical sense along the side of their body), and uses ion channels similar to those that detect extreme temperature, hot chili peppers, wasabi, menthol, and touch.

    Your argument may say WHY such a form survived in certain groups, but it didn't originate with them (in English), or at least I don't believe it did.

English passivizes a verb phrase in two steps: change the "main verb" (or whatever your system of grammar wants to call the most semantic portion of the VP) into the passive participle (third principal part), and insert a form of "to be" immediately before the "main verb."

    Perhaps you confused that second step, the insertion of a form of "to be," with the similar step of inserting a form of "to be" in constructing a progressive (or in this case habitual) aspect.
