Studies Show Neureka! Enhancement During
The research in these two studies,
performed by Dr. Estate Sokhadze at the University of Louisville
Department of Psychiatry, shows the brain produces a higher level of
Neureka! brainwaves when the person feels good.
In the first study, researchers read words
related to positive emotions to subjects who were asked to feel that way
for just 6 seconds. The researchers used the Peak BrainHappiness Trainer
neurofeedback system to measure and record the levels of the Neureka!
brainwave output for the subjects as they felt these emotions. With
all of the positive words, the test subjects showed a significant increase
above the baseline levels in their Neureka! output,. The highest increases
in Neureka! values were for the words “happy” and “joy”.
The baseline they used was taken 2.5 – 3
minutes after the positive words were over. Dr. Sokhadze knew
that anticipating something good caused the Neureka! output to go up at
the start of the study, so the baseline from early in the experiment
couldn’t be used.
The brain produced more Neureka! output when the subject felt
positive emotions. The narrow lines above the bars are the standard
errors of each measurement. The values for each of the positive
feelings were statistically significantly better than baseline.
This graph shows the Neureka! output
level when feeling positive feelings compared to negative or neutral ones.
The Neureka! values during positive feelings were significantly
better than during the repeating numbers and the negative and neutral
In the next experiment, researchers read
emotionally positive, negative and neutral words to the subjects. The
subjects created the feeling of each word inside themselves for 20 seconds
this time, and their Neureka! output was measured by the Peak
BrainHappiness Trainer neurofeedback system. After each group of words,
the subject repeated a 3-digit number for 20 seconds to help the brain
calm down . Using this clearer baseline as a comparison, the
positive emotions raised Neureka! higher than baseline, while the negative
and neutral emotions didn't. The Neureka! associated with positive
emotions was significantly higher than the Neureka! during negative or
This graph shows the difference between the subject's reaction to
two words with a high Neureka! output level, compared to the two words
with lower level of Neureka! output. This indicates how much and how
quickly the brain can change when different types of feelings
These experiments establish that the Neureka! protocol can measure a
variety of positive feelings, in as little as six seconds. The next
study shows that training people with Neureka! can improve their
feelings, thinking and memory.
