| sensation | 1. <physiology> An impression, or the consciousness of an impression, made upon the central nervous organ, through the medium of a sensory or afferent nerve or one of the organs of sense; a feeling, or state of consciousness, whether agreeable or disagreeable, produced either by an external object (stimulus), or by some change in the internal state of the body. "Perception is only a special kind of knowledge, and sensation a special kind of feeling. . . . Knowledge and feeling, perception and sensation, though always coexistent, are always in the inverse ratio of each other." (Sir W. Hamilton) 2. A purely spiritual or psychical affection; agreeable or disagreeable feelings occasioned by objects that are not corporeal or material. 3. A state of excited interest or feeling, or that which causes it. "The sensation caused by the appearance of that work is still remembered by many." (Brougham) Synonym: Perception. Sensation, Perseption. The distinction between these words, when used in mental philosophy, may be thus stated; if I simply smell a rose, I have a sensation; if I refer that smell to the external object which occasioned it, I have a perception. Thus, the former is mere feeling, without the idea of an object; the latter is the mind's apprehension of some external object as occasioning that feeling. "Sensation properly expresses that change in the state of the mind which is produced by an impression upon an organ of sense (of which change we can conceive the mind to be conscious, without any knowledge of external objects). Perception, on the other hand, expresses the knowledge or the intimations we obtain by means of our sensations concerning the qualities of matter, and consequently involves, in every instance, the notion of externality, or outness, which it is necessary to exclude in order to seize the precise import of the word sensation." . Origin: Cf. F. Sensation. See Sensate. Source: Websters Dictionary (01 Mar 1998) |
| sensation disorders | Disorders in the physical response to external or internal stimuli to the senses. (12 Dec 1998) |
| sensation time | The minimal time a visual image must be exposed in order to be perceived. (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) |
