| Cannon-Bard theory | The view that the feeling aspect of emotion and the pattern of emotional behaviour are controlled by the hypothalamus. (05 Mar 2000) |
| whole mount | <procedure> Placing a whole organism or specimen on a slide for microscopic examination. (13 Nov 1997) |
| mount | 1. A mass of earth, or earth and rock, rising considerably above the common surface of the surrounding land; a mountain; a high hill; used always instead of mountain, when put before a proper name; as, Mount Washington; otherwise, chiefly in poetry. 2. A bulwark for offense or defense; a mound. "Hew ye down trees, and cast a mount against Jerusalem." (Jer. Vi. 6) 3. [See Mont de piete] A bank; a fund. Mount of piety. See Mont de piete. Origin: OE. Munt, mont, mount, AS. Munt, fr. L. Mons, montis; cf. L. Minae protections, E. Eminent, menace: cf. F. Mont. Cf. Mount, Mountain, Mont, Monte, Montem. 1. To rise on high; to go up; to be upraised or uplifted; to tower aloft; to ascend; often with up. "Though Babylon should mount up to heaven." (Jer. Li. 53) "The fire of trees and houses mounts on high." (Cowley) 2. To get up on anything, as a platform or scaffold; especially, to seat one's self on a horse for riding. 3. To attain in value; to amount. "Bring then these blessings to a strict account, Make fair deductions, see to what they mount." (Pope) Origin: OE. Mounten, monten, F. Monter, fr. L. Mons, montis, mountain. See Mount, (above). That upon which a person or thing is mounted, as: A horse. "She had so good a seat and hand, she might be trusted with any mount." (G. Eliot) The cardboard or cloth on which a drawing, photograph, or the like is mounted; a mounting. Origin: From Mount. Source: Websters Dictionary (01 Mar 1998) |

| patch clamp | <physiology> A specialised and powerful variant of voltage clamping, in which a patch electrode of relatively large tip diameter (5m) is pressed tightly against the plasma membrane of a cell, forming an electrically tight, gigohm seal. The current flowing through individual ion channels can then be measured. Different variants on this technique allow different surfaces of the plasma membrane to be exposed to the bathing medium: the contact just described is a cell attached patch. If the electrode is pulled away, leaving just a small disc of plasma membrane occluding the tip of the electrode, it is called an inside out patch. If suction is applied to a cell attached patch, bursting the plasma membrane under the electrode, a whole cell patch (similar to an intracellular recording) is formed. If the electrode is withdrawn from the whole cell patch, the membrane fragments adhering to the electrode reform a seal across the tip, forming an outside out patch. (15 Mar 2000) |
| patch-clamp techniques | An electrophysiologic technique for studying cells, cell membranes, and occasionally isolated organelles. All patch-clamp methods rely on a very high-resistance seal between a micropipette and a membrane; the seal is usually attained by gentle suction. The four most common variants include on-cell patch, inside-out patch, outside-out patch, and whole-cell clamp. Patch-clamp methods are commonly used to voltage clamp, that is control the voltage across the membrane and measure current flow, but current-clamp methods, in which the current is controlled and the voltage is measured, are also used.

| Payr's clamp | A clamp used in gastrectomy or enterectomy. (05 Mar 2000) |
| glucose clamp technique | <technique> Maintenance of a constant blood glucose level by perfusion or infusion with glucose or insulin. It is used for the study of metabolic rates (e.g., in glucose, lipid, amino acid metabolism) at constant glucose concentration. (12 Dec 1998) |
| voltage clamp | <physiology, technique> A technique in electrophysiology, in which a microelectrode is inserted into a cell and current injected through the electrode so as to hold the cells membrane potential at some predefined level. The technique can be used with separate electrodes for voltage sensing and current passing, for small cells, the same electrode can be used for both. Voltage clamp is a powerful technique for the study of ion channels. See: patch clamp. (18 Nov 1997) |
| Goldblatt's clamp | A clamp applied experimentally to the renal artery to damp pulse pressure and thereby produce chronic hypertension by activation of the renin-angiotensin system. (05 Mar 2000) |
