|---|---|---|---|
| 설명 | 청신경(제8뇌신경)의 신경겉을 싸고 있는 집(sheath)의 슈반세포(Schwann cell)에서 기원하는 종양-뇌종양 중 비교적 흔하며 대개 40~50대에 호발한다. 증상으로는 귀울림, 난청, 소뇌기능장애 등이 있으며, 이중 귀울림이 가장 초기의 증상이다. |

|---|---|---|---|
| 설명 | 외부로부터 들어온 자극을 잘못 판단하는 것을 착각이라고 한다. 외부에서 들어온 자극을 받아들이는 말초감각기관은 정확히 자극을 받아 들였지만 이것을 해석하는 뇌의 작용의 이상으로 그 자극을 과소, 과대평가하거나 다른 것으로 생각하는 것이다. 예를 들면 멀리서 걸어오는 처음 보는 여자를 자신의 애인으로 잘못보는 것이 착각이다. 이런 현상은 독성물질에 의한 뇌실질의 장애, 뇌의 감염, 알코올성 정신병, 뇌의 변성 등 뇌 자체의 병으로 인한 혼돈된 상태나 다른 전신의 장애, 즉 고열, 심한 전신쇠약 등에서 생기는 혼돈상태에서 나타날 수가 있다. 그리고 정상적인 상태에서도 볼 수 있다. |

| illusion | 1. <psychology> An unreal image presented to the bodily or mental vision; a deceptive appearance; a false show; mockery; hallucination. "To cheat the eye with blear illusions." (Milton) 2. Hence: Anything agreeably fascinating and charning; enchantment; witchery; glamour. "Ye soft illusions, dear deceits, arise!" (Pope) 3. <physiology> A sensation originated by some external object, but so modified as in any way to lead to an erroneous perception; as when the rolling of a wagon is mistaken for thunder. Some modern writers distinguish between an illusion and hallucination, regarding the former as originating with some external object, and the latter as having no objective occasion whatever. Illusion refers particularly to errors of the sense, delusion to false hopes or deceptions of the mind. An optical deception is an illusion, a false opinion is a delusion. Synonym: Delusion, mockery, deception, chimera, fallacy. Origin: F. Illusion, L. Illusio, fr. Illudere, illusum, to illude. Source: Websters Dictionary (01 Mar 1998) |

| illusion of doubles | <syndrome> The delusional belief that a person (or persons) close to the schizophrenic patient has been substituted for by one or more impostors; may have an organic aetiology. Synonym: Capgras' phenomenon, illusion of doubles. (05 Mar 2000) |
| illusion of movement | Successive stimulation of neighboring retinal points which causes the sensation of movement. Oculogravic illusion, apparent movement of the visual field when the body is subjected to acceleration; due to gravity. Oculogyral illusion, an illusion occurring in angular acceleration in which the position of fixed light appears to drift. Optical illusion, a false interpretation of the colour, form, size, or movement of a visual sensation. (05 Mar 2000) |
| acoustic | Pertaining to the sense of hearing, the organs of hearing, or the science of sounds; auditory. Acoustic duct, the auditory duct, or external passage of the ear. Acoustic telegraph, a telegraph making audible signals; a telephone. Acoustic vessels, brazen tubes or vessels, shaped like a bell, used in ancient theaters to propel the voices of the actors, so as to render them audible to a great distance. Origin: F. Acoustique, Gr. Relating to hearing, fr. To hear. A medicine or agent to assist hearing. Source: Websters Dictionary (01 Mar 1998) |
| acoustic agraphia | The inability to write from dictation. (05 Mar 2000) |
| acoustic aphasia | An impairment in comprehension of the auditory forms of language and communication, including the ability to write from dictation in the presence of normal hearing. Spontaneous speech, reading, and writing are not affected. Synonym: acoustic aphasia, word deafness. (05 Mar 2000) |
| acoustic area | The floor of the lateral recess of the fourth ventricle, extending medially to the limiting sulcus and overlying the cochlear and vestibular nuclei of the rhombencephalon. Synonym: area acustica. (05 Mar 2000) |
| acoustic cell | A hair cell of the organ of Corti. (05 Mar 2000) |
| acoustic crest | An elevation on the inner surface of the ampulla of each saemicircular duct; filaments of the vestibular nerve pass through the crista to reach hair cells on its surface; the hair cells are capped by the cupula, a gelatinous protein-polysaccharide mass. Synonym: crista ampullaris, acoustic crest, transverse septum. (05 Mar 2000) |
| acoustic enhancement | A manifestation of increased acoustic signal amplitude returning from regions beyond an object which causes little or no attenuation of the sound beam. Compare: acoustic shadow. (05 Mar 2000) |
| acoustic impedance | The resistance that a material offers to the passage of a sound wave (colloquial); a property of a medium computed as the product of density and sound propagation speed (characteristic acoustic impedance). Discontinuities in acoustic impedance are responsible for the echoes on which ultrasound imaging is based. Unit: the rayl. (05 Mar 2000) |
| acoustic impedance tests | Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance). (12 Dec 1998) |
| acoustic lemniscus | A bundle of ascending fibres that originate from the cochlear and auditory relay nuclei of the rhombencephalon, enter the trapezoid body, a transverse fibre stratum in which about half their number decussate, and from here turn rostrally along the lateral side of the spinothalamic tract; in the midbrain, it arches dorsally and enters the inferior colliculus in which all of its fibres terminate; the auditory pathway is transsynaptically extended from here by the brachium of the inferior colliculus to the medial geniculate body of the thalamus, from which in turn the auditory radiation leads to the auditory cortex; intercalated in the trapezoid body and along the ascending trajectory of the lemniscus are several cell groups in which part of the fibres synapse. Synonym: lemniscus lateralis, acoustic lemniscus, auditory lemniscus, auditory tract, lateral fillet. (05 Mar 2000) |
| acoustic lens | In ultrasonography, a lens used to focus or diverge a sound beam; may be simulated by electronic manipulation of signals. (05 Mar 2000) |
| acoustic maculae | Thickened areas of the saccule and utricle where the termination of the vestibular nerve occurs. (12 Dec 1998) |
