Brain Waves (Part 1)

Several experiments had been televised.

For example, "Spa Spa Ningengaku (Humanics)" on October 7, 2004...

On the TV program, instantaneous exercises (dumbbell exercises) and stamina exercises (bicycle machines) were investigated, for the purpose of elucidating the reason that people cannot continue exercises, according to blood type. 

The next results were provided by measuring brain waves during exercises.


  Instantaneous Exercises Stamina Exercises
Type A Much stress Little stress
Type B Little stress Much stress
Type AB Different by person Different by person
Type O Little stress Little stress


Very different by blood types. 

Type O seems to have less stress ... and will be mentionde later in part 3.  

Brain Waves (Part 2)

Another experiment by professor Noriyuki Yoshida, the faculty of human and social environment, Hiroshima International University, was introduced Hiroshima International University, was introduced on a TV program "Aru Aru Daijiten" on October 3, 2004.


This is also a very interesting experiment to measure differences of brain waves of 40 subjects (both males and females) according to blood types.  Subjects push a button if a light is on and release it if the light is off with one's eyes closed.  Brain waves among these two states are analyzed. 

  • Point 1: How do brain waves react to light stimulation?
  • Point 2: After light stimulation, how long does it take for brain waves to return to the original state?

The results were fantastic!

When we assume degree of brain waves excitement as [quantity β band / (quantity of α band + quantity of β band)], the degree was type A > type O > type AB > type B in order.  In other words, to react to stimulation of the outside world in this order.

Differences of brain-wave excitement by blood types mean differences of optic nerve and/or brain reactions by blood types.  Finding differences of reaction by blood types would be demonstrated at cerebrum physiology level (aside from the mechanism) for the first time! 

Brain Waves (Part 3)

In Korea, a brain-wave research was conducted. 


Title: A study on the effects of one's blood type on emotional character and antistress of adults

Journal of the Korea Academia-Industrial cooperation Society
vol. 12 no.6, 2011, pp.2554-2560

Authors: Choong-Shik Kim and Seon-Gyu Yi, Dept. of Information Management Seoul University of Venture & Information


This study is focused on the effects of one's blood type on emotional character and anti-stress by comparing each individual's brain wave.

Observed records are from those kids who volunteered for KRIJUS (Korea Research Institute of Jungshin Science)'s brain wave measurement from September 2006 to December 2009.

he whole 4636 adult(20-59 age) group consists of 3221 female and 1415 male. Blood types are as follows; A>B>O>AB dominately ordered.

The result shown no relations between the blood types of adult and their emotional character. But meaningful difference had been revealed between the blood type and stress resistancy; type O rated higher scores in awareness and stress resistancy then other types, which shows that type O has more ability to reduce its stress.

This study revealed meaningful relation between blood types and emotional character among several categories, while suggesting follow-up researches figuring out more detailed explanations for its effect and genetic role. 

The next is a study of photo topography.
