ABOUT

Everyone has their own ways of enjoying some me-time, like soaking in a warm bath, drinking a cup of coffee, stretching, and self-pleasure. During these moments of indulgence, our brains send a variety of signals, adapting and changing without our conscious effort.
What sort of changes are taking place? What sort of "pleasure" ignites those changes?
We tested to see what brainwaves are sent out during small moments of bliss.

EXPERIMENT

Experiment Overview

Experiment Overview

■ Date: October 3rd, 2016
■ Place: Home Studio in Tokyo
■ Method: A brainwave sensor would record brainwaves of a female model during various relaxation activities.
・Brainwaves were scanned at resting state, and before and after activities including drinking a cup of coffee, lighting and enjoying aromatic candles, and masturbation with iroha products.

Results

Coffee Use of iroha
Coffee 0Hrz α波(8〜13Hrz) 25Hrz Use of iroha 0Hrz α波(8〜13Hrz) 25Hrz
α (alpha) waves α waves are brain waves seen between 8~13Hz.
These are commonly seen during states of relaxation.

・Strong α waves were observed around the occipital lobe in relaxing activities other than masturbation with iroha products.
・After masturbation with iroha, α waves were observed around the occipital lobe as with other relaxation methods, but after approximately 5~6 minutes, an increase in α waves were also observed in areas that were not affected by other relaxation methods. These effects were similar to those observed in states of meditation.
*Note: These are only results of a single example, and may not apply to all cases.

Full Experiment Commentary

First, we explored methods of relaxation such as "drinking coffee" and "enjoying aromatic candles." After these activities we observed a strong presence of α waves around the occipital lobe, which is something that is said to be a strong indicator of a relaxed state.・・・Read More

After masturbation with iroha, we observed the same presence of α waves around the occipital lobe, but unlike the other activities, after 5~6 minutes we noticed the α waves had spread from the occipital lobe to an area spanning the parietal lobe to the frontal lobe.
From the observation of α waves spreading to the frontal lobe, we hypothesize that the use of iroha could assist in people reaching a state of relaxation close to that of meditation.
That said, these are only the results of a single-case experiment, and may not apply to all cases.
To be able to verify the accuracy of this result, there is a need to increase the samples of the experiment. However, I do think it was a rather interesting discovery. (Naotaka Fujii - Team Leader, Institute of Physical and Chemical Research) Close
