| negative cooperativity | Cooperativity in which successive ligand molecules appear to bind with decreasing affinity. (05 Mar 2000) |
|---|---|
| negative crystal | <microscopy> A uniaxial crystal is optically negative if epsilon is less than omega A biaxial crystal is said to be optically negative if gamma minus beta is less than beta is less than beta minus alpha. Otherwise the crystal is positive. (05 Aug 1998) |
| negative electrode | <chemistry, physics> The electrode in an electrochemical cell toward which cations are drawn and where reduction occurs. The negatively charged electrode in a vacuum tube. (16 Mar 1998) |
| negative electrotaxis | Electrotaxis by which an organism is attracted toward an anode or repelled from a cathode. (05 Mar 2000) |
| negative end-expiratory pressure | A subatmospheric pressure at the airway at the end of expiration. (05 Mar 2000) |
| negative eyepiece | <microscopy> An eyepiece in which the real image of the object is formed between the lens elements of the eyepiece. (05 Aug 1998) |
| negative, false | A result that appears negative but fails to reveal a situation. An example of a false negative: a particular test designed to detect cancer of the toenail is negative but the person has toenail cancer. (12 Dec 1998) |
| negative focal length | <physics> The focal length of a negative lens. Parallel rays impinging on a negative lens can be traced to a virtual focus which exists on the same side of the lens as the impinging rays. The distance from the second principal point of the lens to this second focal point is measured on the same side of the lens as is the object. See: negative lens, focal length. (05 Aug 1998) |
| negative G | Gravity in a foot-to-head direction in flying, or in standing on one's head; opposite of positive G. (05 Mar 2000) |
| negative image | Continuation of visual impression after cessation of stimuli causing the original image. (12 Dec 1998) |
| negative lens | <physics> A lens with a negative focal length. The edge of a negative lens is thicker than the centre. The three negative lenses are, according to their figure: planoconcave, double concave or biconcave, and diverging concavoconvex or diverging meniscus. See: lens, simple. (05 Aug 1998) |
| negative meniscus | A convexoconcave lens in which the power of the concavity exceeds that of the convexity. Synonym: negative meniscus. (05 Mar 2000) |
| negative phase | The period during which the opsonic index is lowered following the injection of a vaccine. (05 Mar 2000) |
| negative pressure | Pressure less than that of the ambient atmosphere. (05 Mar 2000) |
| negative regulation | Negative feedback in biological systems mediated by allosteric regulatory enzymes. (18 Nov 1997) |

| negative feedback |
feedback in which a portion of the signal from a later amplifier stage is fed back to an earlier stage (or to the same stage) in such a manner as to subtract from the input signal.

| negative feedback |
A Feedback loop that tends to slow or counter a response to an input to the system and helps promote self-regulation (helps keep system in balance).
