What is the definitive guide to Adam Ringham's neuroplasticity and neurohacking techniques?

Based on the available content, Adam Ringham delves into the realm of neurohacking and neuroplasticity, exploring innovative concepts like the use of Terahertz waves and inducing synesthesia. He encourages his audience to learn more about these fascinating topics, which could potentially allow one to "see sounds" or "hear colors".

However, I don't have a definitive guide to Adam's techniques at my disposal. Adam's approach seems to be about sharing insights and sparking curiosity rather than providing a step-by-step guide.

Would you like to know more about a specific aspect of neurohacking or neuroplasticity that Adam discusses? Or perhaps you're interested in how Terahertz waves and synesthesia relate to these topics?
