| SMR | Sensorimotor rhythm |
|---|---|
| SMC | sensorimotor cortex |
| sensorimotor | Both sensory and motor; denoting a mixed nerve with afferent and efferent fibres. Synonym: sensomotor. (05 Mar 2000) |
|---|---|
| sensorimotor area | The precentral and postcentral gyri of the cerebral cortex. (05 Mar 2000) |
| sensorimotor theory | In the developmental theory of Piaget, the postulation that during the first 18 months of life there occurs a transformation of action into thought; at first there is a gradual shift from inborn to acquired behaviour, then from body-centreed to object-centreed activity, ultimately permitting intentional behaviour and inventive thinking.

| cardiac gating | Using an electronic signal from the cardiac cycle to trigger an event, such as in imaging separate phases of cardiac contraction. (05 Mar 2000) |
| gating | 1. In a biological membrane, the opening and closing of a channel, believed to be associated with changes in integral membrane proteins. 2. A process in which electrical signals are selected by a gate, which passes such signals only when the gate pulse is present to act as a control signal, or passes only the signals that have certain characteristics. See: gate. (05 Mar 2000) |
| gating current | <physiology> Small currents in the membrane just prior to the increase in ionic permeability, due to the movement of charged particles within the membrane. So called because they open the gates for current flow through ion channels. (20 Mar 1998) |
| gating mechanism | Occurrence of the maximum refractory period among cardiac conducting cells approximately 2 mm proximal to the terminal Purkinje fibres in the ventricular muscle, beyond which the refractory period is shortened through a sequence of Purkinje cells, transitional cells, and muscular cells; gating mechanism may be a cause of ventricular aberration, bidirectional tachycardia, and concealed extrasystoles, a mechanism by which painful impulses may be blocked from entering the spinal cord. Compare: gate-control theory. (05 Mar 2000) |
| channel gating | <physiology> Small currents in the membrane just prior to the increase in ionic permeability, due to the movement of charged particles within the membrane. So called because they open the gates for current flow through ion channels. (20 Mar 1998) |
| ion channel gating | The opening and closing of ion channels due to a stimulus. The stimulus can be a change in membrane potential (voltage-gated), drugs or chemical transmitters (ligand-gated), or a mechanical deformation. Gating is thought to involve conformational changes of the ion channel which alters selective permeability. (12 Dec 1998) |
