Quote of the Week

“I personally didn’t feel any stress. I was just having a lot of fun out there and I think that’s what helped because I wasn’t thinking at all about anything that was out of my control or going on off the court. I was just really focusing in on my matches.”

Emma Raducanu (#9 FCAR)

ABOUT the Brain Type® Institute

How does JN do it?

Though Jonathan P. Niednagel and BTI are diligently working to precisely identify the 16 different BTs by scientific methods alone (genetics, neuroimaging/ mapping, and biomechanical analysis), how has JN been able to assess people the empirical way?

The BTI Advisory Team

Assembling a collection of notables in their respective vocations and fields of expertise who can contribute in the key areas that Brain Typing® is being focused has been a top priority for BTI.

BTI Research

BTI began genetic research of the various Brain Types® in the mid-1990’s. Neurotransmitter DNA analysis was done at a prominent American university. Though neurotransmitter evaluation is still ongoing, BTI has also ventured into other genetic fields, searching for additional clues.
