|---|---|---|---|
| 설명 | 눈을 한곳에 고정시킨 채, 관찰할 수 있는 주변공간을 시야라 한다. 시야를 검사하는 가장 간단한 방법은 대면검사(confronting test)이다. 이것은 피검사자의 눈을 검사자의 눈에 맞추어 보도록 하여 눈을 고정시킨채, 검사자가 손가락끝을 위쪽, 아래쪽, 왼쪽, 오른쪽, 그리고 비스듬히 경사진 곳 등으로 옮겨보아 피검사자가 관찰할 수 있는지 여부를 정하는 검사법이다. 이보다 정확한 검사법은 자동식 컴퓨터시야검사법이 있다. 대개, 눈자체의 이상이 있어도 시야검사에서 이상이 나오지만, 이외 뇌의 이상으로 시각의 형성경로에 이상이 있어도 역시 이상소견을 보인다. |

| field-vole | A species of field mouse (Microtus montebelloi), normal host of Leptospira hebdomadis, the cause of a type of leptospirosis resembling infectious mononucleosis. (05 Mar 2000) |

| vole | <zoology> Any one of numerous species of micelike rodents belonging to Arvicola and allied genera of the subfamily Arvicolinae. They have a thick head, short ears, and a short hairy tail. The water vole, or water rat, of Europe (Arvicola amphibius) is a common large aquatic species. The short-tailed field vole (A. Agrestis) of Northern and Central Europe, and Asia, the Southern field vole (A. Arvalis), and the Siberian root vole (A. Oeconomus), are important European species. The common species of the Eastern United States (A. Riparius) (called also meadow mouse) and the prairie mouse (A. Austerus) are abundant, and often injurious to vegetation. Other species are found in Canada. Source: Websters Dictionary (01 Mar 1998) |

| auditory field | The space included within the limits of hearing of a definite sound, as of a tuning fork. (05 Mar 2000) |
| bright field illumination | <microscopy> The method of lighting the specimen with a solid cone of rays. Transmitted bright field illumination is performed by a substage condenser. Reflected bright field illumination is performed by a vertical illuminator. Compare: dark field illumination (05 Aug 1998) |
| bright field imaging | <microscopy> An imaging mode in a transmission electron microscopy that uses only unscattered Electrons to form the image. Contrast in such an image is due entirely to mass-thickness variations in amorphous samples, and may include diffraction contrast in crystalline samples. (05 Aug 1998) |
| bright field microscopy | <technique> Optical microscopy, in which absorption to a great extent and diffraction to a minor extent give rise to the image, as opposed to phase contrast or interference methods of microscopy. (18 Nov 1997) |
| Broca's field | The posterior part of the inferior frontal gyrus of the left or dominant hemisphere, corresponding approximately to Brodmann's area 44; Broca identified this region as an essential component of the motor mechanisms governing articulated speech. Synonym: Broca's area, Broca's field, motor speech centre. (05 Mar 2000) |
| cardioid dark field condenser | <microscopy> A condenser designed with two reflecting surfaces, the first, a spherical surface which reflects the rays to a second, cardioid (heart-shaped) surface. The virtue in such an arrangement is that, if the cardioid surface is of true figure, the lens is both achromatic and aplanatic. It has a limiting numerical aperture of about 1.0. Thus objectives of a greater numerical aperture cannot be used successfully with it. A true cardioid figure is the trace of a point on the circumference of a circle rolling around an equal, fixed circle. (05 Aug 1998) |
| magnetic field | The sphere of influence of a magnet. (05 Mar 2000) |
| magnetic field gradient | In magnetic resonance imaging, a magnetic field that varies with location, superimposed on the uniform field of the magnet, to alter the resonant frequency of nuclei and allow recovery of their spatial position. Synonym: field gradient. (05 Mar 2000) |
| paraboloid dark field condenser | <microscopy> A lens of parabolic shape. The vertex end is ground back so that its focus can be brought into coincidence with the specimen on the slide. A central stop is provided to block the central rays. It is used chiefly for medium- power work. (05 Aug 1998) |
| receptive field | That part of the retina whose photoreceptors (rods and cones) pertain to a single optic nerve fibre. The response of a neuron to stimulation of its receptive field depends on the type of neuron and the part of the field that is illuminated; an "on-centre" neuron is stimulated by light falling at the centre of its receptive field and inhibited by light falling at the periphery; an "off-centre" neuron reacts in exactly the opposite fashion; that is, it is inhibited by light falling at the centre of its receptive field. In either case, the net response depends on a complex switching action in the retina. When an entire receptive field is equally illuminated, the response of receptors at the centre of the field predominates. (05 Mar 2000) |
| visual field | The area simultaneously visible to one eye without movement; often measured by means of a bowl perimeter located 330 mm from the eye. (05 Mar 2000) |
