| Isapt | spatial peak, temporal average intensity [pulse] |
| DSR | Dynamic Spatial Reconstructor |

| USN | Unilateral Spatial Neglect |
| visual-spatial agnosia | The inability to localise objects or to appreciate distance, motion, and spatial relationships; caused by lesion in the occipital lobe. Compare: simultanagnosia. (05 Mar 2000) |
|---|---|
| agnosia | <neurology> Loss of ability to recognise objects, people, sounds, shapes or smells. Usually classified according to the sense or senses affected (hearing, sight, smell, taste, touch). Symptom common to tumours of the parietal lobe of the cerebral hemispheres. (16 Dec 1997) |
| auditory agnosia | The inability to recognise sounds, words, or music; caused by a lesion of the auditory cortex of the temporal lobe. (05 Mar 2000) |
| visual agnosia | The inability to recognise objects by sight; usually caused by bilateral parieto-occipital lesions. Synonym: optic agnosia. (05 Mar 2000) |
| colour agnosia | The inability to name or identify specific colours by sight; caused by lesions of the dominant occipital and temporal lobes. (05 Mar 2000) |
| position agnosia | The failure to recognise the posture of an extremity. (05 Mar 2000) |
| spatial | Relating to space or a space. (05 Mar 2000) |
| spatial acuity | The detection of the shape of a test object; e.g., perceiving polygons of the same size but with different numbers of sides. (05 Mar 2000) |
| spatial behaviour | Reactions of an individual or groups of individuals with relation to the immediate surrounding area including the animate or inanimate objects within that area. (12 Dec 1998) |
| spatial filter | <radiobiology> Device consisting of a lens pair and a pinhole aperture stop. Intensity fluctuations over the spatial extent of a laser beam are removed by passing the focused beam through the aperture stop. The pinhole must be placed in a vacuum to prevent air breakdown by the focused beam. These filters are used to counter the effects caused by self-focusing. (09 Oct 1997) |
| spatial formula | A chemical formula in which the arrangement of the atoms or atomic groupings in space are indicated. Synonym: spatial formula. (05 Mar 2000) |
| spatial localization | The reference of a visual sensation to a definite locality in space. (05 Mar 2000) |
| spatial sensing | Mechanism of sensing a gradient in which the signal is compared at different points on the cell surface and cell movement directed accordingly. Translocation of all or part of the cell is not required. See: temporal gradient sensing, pseudospatial gradient sensing. (18 Nov 1997) |
| spatial vector | A cardiac vector represented in more than one plane simultaneously; two-or three-dimensional orientation of a vector. (05 Mar 2000) |
| spatial vectorcardiography | Three-dimensional vectorcardiography in which vector loops are inscribed in frontal, sagittal, and horizontal planes. (05 Mar 2000) |
