| 설명 | 대뇌의 신경세포는 자발적인 활동을 하면서 전기적인 신호를 내보낸다. 이 신경세포의 전기적인 신호를 일정한 영역에서 집합적으로 얻어내서 기록한 것을 뇌파라 한다. 본래 뇌파는 시시각각으로 변화하는 뇌의 전기적 신호이지만, 연속적으로 기록하면 여러 형태의 파형으로 나타나기 때문에 뇌파라고 한다. 일반적으로 두피 위에서 기록한 두피뇌파외에 뇌속으로 전극을 넣어서 전기활동을 기록하는 심부뇌파가 있다. 1.주파수-가장 기본이 되는 뇌파는 8~13Hz의 주기를 가지는 알파파, 13~30Hz의 주기를 가지는 베타파, 4~7Hz의 주기를 가지는 데에타파, 0.5~3Hz의 주기를 가지는 람다파, 30Hz이상의 주기를 가지는 감마파로 분류된다. 정상 성인의 안정, 각성상태로 눈을 감고 있을 때의 기본파는 알파파가 주체를 이루고 있다. 베타파는 눈을 뜨고 있을 때나 긴장이 고조되었을 때 나타난다. 데에타파와 람다파는 서파라고 하며, 성인에게서 이런 파가 나타나면 이상상태로 진단된다. 어린이의 경우에는 정상시에도 데에타파가 출현한다. 2.진폭 또는 전위-기록상 50uV의 전위를 5~7mm가 되도록 조정한다. 150uV이상의 고전위를 가진 서파는 대뇌의 기능저하를 나타내고, 대뇌피질의 기능정지는 평탄파로 나타난다. 3.이상파-기본파와 그 파형, 진폭이 뚜렷히 다른 파를 이상파라고 한다. 이상파에는 극파(spike), 예파, 고전위파, 극서파결합 등이 있다. 이 파들은 간질 진단의 유력한 정보가 된다. 뇌파검사는 거의 모든 신경질환의 진단에 응용된다. 간질, 뇌종양, 뇌혈관장애, 두부외상, 염증, 변성질환, 선천기형 등의 진단에 응용된다. 뇌파는 뇌의 기능이상을 표현하는 것이므로, 뇌의 형태적이상을 나타내는 CT 등의 검사결과와 반드시 일치하지는 않는다는 점에 주의해야 한다. 즉 뇌파는 뇌의 기능이 정상적인가, 이상이 있는가, 만일 이상이 있다면 어디에 어느 정도의 장애가 있으며, 이 장애는 장차 어떻게 진전할까 등에 대해서 유력한 정보를 제공한다. 뇌파가 진단의 주요 무기가 되는 질환은 간질, 뇌의 국소적 기능이상, 의식장애, 특이적 이상파가 출현하는 질환 등이다. |

| EEG | <investigation> A diagnostic test which measures the electrical activity of the brain (brain waves) using high sensitive recording equipment attached to the scalp by fine electrodes. Commonly employed in the evaluation of neurological disease (for example seizures, epilepsy, etc.). Acronym: EEG (13 Nov 1997) |
| EEG activation | The low voltage, fast pattern of attentive wakefulness. (05 Mar 2000) |
| antibody technology | <molecular biology> Techniques for the synthesis of polyclonal and monoclonal antibodies for use in research, diagnostics and therapeutics. (09 Feb 1998) |
| assisted reproductive technology | Originally, a range of techniques for manipulating eggs and sperm in order to overcome infertility. Encompasses drug treatments to stimulate ovulation; surgical methods for removing eggs (e.g., laparoscopy and ultrasound-guided transvaginal aspiration) and for reimplanting embryos (e.g., zygot intrafallopian transfer (or ZIFT); in vitro and in vivo fertilization (e.g., artificial insemination and gamete intrafallopian transfer (or GIFT); ex utero and in utero foetal surgery; as well as laboratory regimes for freezing and screening sperm and embryos, and micromanipulating and cloning embryos. The field's first major success came in 1978 with the birth of "test-tube baby" Louise Brown, engineered by Steptoe, Edwards, et al., of England. As the technologies spread, they increasingly are being employed for purposes beyond infertility, i.e., to reduce the risk of, or avoid passing on, hereditary disease and to select for infant sex. Further uses that would aim at improving the "quality" of offspring have been widely discussed and raise profound legal and ethical questions. See: eugenics. (05 Mar 2000) |
| recombinant DNA technology | A series of procedures used to join together (recombine) DNA segments. A recombinant DNA molecule is constructed (recombined) from segments from 2 or more different DNA molecules. Under certain conditions, a recombinant DNA molecule can enter a cell and replicate there, autonomously (on its own) or after it has become integrated into a chromosome. (12 Dec 1998) |
| national centre for health care technology | A centre in the public health service which coordinates and administers a program of research, demonstrations, and evaluations of medical technologies and assessments of health care technology. (12 Dec 1998) |
| DNA technology, recombinant | A series of procedures used to join together (recombine) DNA segments.

| technology | <study> Industrial science; the science of systematic knowledge of the industrial arts, especially of the more important manufactures, as spinning, weaving, metallurgy, etc. Technology is not an independent science, having a set of doctrines of its own, but consists of applications of the principles established in the various physical sciences (chemistry, mechanics, mineralogy, etc) to manufacturing processes. Origin: Gr. An art; cf. Gr. Systematic treatment: cf. F. Technologie. Source: Websters Dictionary (01 Mar 1998) |
