Description
【発明の詳細な説明】 〔発明の技術分野〕 本発明は脳の活動を測定する装置に関する。[Detailed description of the invention] [Technical field of invention] The present invention relates to a device for measuring brain activity.
（発明の技術的背景とその問題点）
従来、脳の活動を測定するためには脳波計を用いたり、
放射性同位元素を用いたりする必要があった。このため
測定はおおがかりで、しかも、専門的な知識を持った専
門家の立会いを必要とした。(Technical background of the invention and its problems) Conventionally, electroencephalography was used to measure brain activity,
It was necessary to use radioactive isotopes. For this reason, measurements were extensive and required the presence of experts with specialized knowledge.
（発明の目的）
本発明はこのような事情を考慮してなされたもので、そ
の目的は、簡単に脳の活動を測定できる手段を提供する
ことにある。(Object of the Invention) The present invention has been made in consideration of the above circumstances, and its purpose is to provide a means for easily measuring brain activity.
本発明は耳に流れる血流量を測定することによって間接
的に脳の活動を測定するものである。興奮したときに耳
が赤くなったりすることが経験的に知られている。これ
は脳の活動と相関関係があるものと考えられる。しかし
、よく注意してみると、耳の変化は右と左で異なってい
る。これは四Ｓが感情を主体とするものであったり、理
性を主体とするものであったりするために、右脳が活動
したり左脳が活動したりするために起こる現象であると
推定される。この現象は無侵襲で測定が可能である。The present invention indirectly measures brain activity by measuring the amount of blood flowing to the ears. It is known from experience that the ears turn red when excited. This is thought to be correlated with brain activity. However, if you pay close attention, you will notice that the changes in the right and left ears are different. This is presumed to be a phenomenon that occurs because the right hemisphere is activated and the left hemisphere is activated because the four S's are mainly based on emotion or rationality. This phenomenon can be measured non-invasively.
従って、耳介の血流量を用いる本発明によれば、手軽に
危険もなく脳の活動を測定することが可能となる。Therefore, according to the present invention, which uses blood flow in the auricle, brain activity can be easily and safely measured.
（発明の実施例〕
以下に図面を参照して、本発明の具体的実施例について
説明する。(Embodiments of the Invention) Specific embodiments of the present invention will be described below with reference to the drawings.
第１図は本発明の構成を示すブロック図である。FIG. 1 is a block diagram showing the configuration of the present invention.
図中１は耳介の血流量を測定する手段である。無侵襲で
血流量を測定するには第２図に示すように耳介の色を識
別するのが有効である。特に血流量が多くなると耳介が
赤くなるので、赤い色の識別を行なうのが最もよい。第
２図中、１（２）の例では、耳介３のある位置からの反
射光をレンズ系４と赤フィルタ６を通して受光器５で光
電変換する。同じ位置からの反射光はレンズ系４′を通
してフィルタを通さずに受光器５′で光電変換される。In the figure, 1 is a means for measuring blood flow in the auricle. In order to non-invasively measure blood flow, it is effective to identify the color of the auricle as shown in FIG. In particular, when the blood flow increases, the auricle turns red, so it is best to identify the color red. In the example 1 (2) in FIG. 2, reflected light from a certain position of the auricle 3 is photoelectrically converted by the light receiver 5 through the lens system 4 and the red filter 6. The reflected light from the same position passes through a lens system 4' and is photoelectrically converted by a light receiver 5' without passing through a filter.
これらの光電変換結果を色識別手段７で比較することに
より、耳介の赤い色が識別される。By comparing these photoelectric conversion results with the color identification means 7, the red color of the auricle is identified.
また、第３図中、１υに示すように発光器８と受光器５
″を組み合わせて固定手段９で耳介に固定し、耳介の光
の透過率を透過率測定手段１０で測定したり、第４図中
、１（Ｃ）に示すように温度センサ１１と温度測定手段
１２で耳介の温度を測定するのが有効である。In addition, as shown at 1υ in FIG. 3, a light emitter 8 and a light receiver 5
'' is fixed to the auricle using the fixing means 9, and the light transmittance of the auricle is measured using the transmittance measuring means 10, or the temperature sensor 11 and the temperature sensor 11 are used as shown in FIG. It is effective to measure the temperature of the auricle using the measuring means 12.
第１図中２は血流量を脳の活動量に変換する手段である
。具体的には第５図中、２（２）に示すようにテーブル
を引く方式が最も容易に実現できる。2 in FIG. 1 is means for converting blood flow into brain activity. Specifically, the method of drawing a table as shown in 2(2) in FIG. 5 can be most easily realized.
血流量測定手段はアナログの電気信号で得られる場合が
多いので、Ａ 、／ Ｄ変換手段１３によってディジタ
ル信号に変換する。この結果を変換テーブル・メモリ１
４のアドレスとしてメモリを参照し、その出力を出力手
段１５により数値１色、メータの振れ等に変換して出力
する。テーブルの値は心理物理学的実験によって求める
ことができる。Since the blood flow measurement means is often obtained as an analog electrical signal, it is converted into a digital signal by the A/D conversion means 13. Convert this result to table memory 1
The memory is referred to as address 4, and the output is converted into a numerical value, one color, meter deflection, etc., and outputted by the output means 15. The values in the table can be determined by psychophysical experiments.
また、右脳と左脳の内、活動の主体となっているほうを
知るためには、左右の耳介の血流量の差を求めればよい
。そのためには第６図中、２（ハ）に示すように、差動
増幅器１６を用いればよい。Additionally, to find out which brain is more active, the right brain or the left brain, it is sufficient to find the difference in blood flow between the left and right auricles. For this purpose, a differential amplifier 16 may be used as shown in 2(c) in FIG.
以上説明したように、本発明によれば、無侵襲で手軽に
脳の活動を測定することができる。この測定には特殊な
技能も専門的な知識も必要ではなく、橿めて実用上有利
である。As explained above, according to the present invention, brain activity can be easily measured non-invasively. This measurement does not require any special skills or specialized knowledge, and is therefore advantageous in practice.
