Neuroplasticity

Neuroplasticity is the ability of the brain to change its default activity by modifying its own connectivity. It is an important evolved feature as it enables the brain to rewrite its software as unforeseen circumstances arise. As we age we this ability degrades, psychedelics can reopen the neuroplastic window.

Figure 2. The fused brain

When young, humans are extremely neuroplastic (see Figure 1) meaning when an experience demands, it doesn't take much energy change the brains default behaviour. Neuroplasticity declines through age, leading to a more fused brain (see Figure 2). Recent studies have shown neuroplasticity can be temporarily improved by inducing pivotal mental states.

Structure-Activity

The brain is neurochemical in nature, meaning it is part electric and part chemical. When these systems combine to provide brain function they work like hiking trails; the pathways that get a lot of traffic get smoother and wider, with brush stomped down and pushed back. The neural pathways that sit unused grow over, becoming less likely to be used. Your brain uses the more accessible pathways as it takes lower energy to do so.
