This is super interesting, researchers in neuroscience are simoutaneously coming to the same conclusions about freestlying rapping as they are about what happens when you eat mushrooms. Basically your brain lets its guard down. "So what did we learn in this experiment? Quite a bit, as it happens. The key finding is the dissociation of two prefrontal areas during spontaneous composition of artistic content. The medial prefrontal cortex showed increased activity, and the dorsolateral prefrontal cortex – DLPFC for short – showed decreased activity. While the former has been in the news lately for its association with various aspects of social cognition – self-perception, self-knowledge, moral decisions, etc. – the DLPFC has long been known to mediate the so-called higher mental functions: executive attention, working memory, willed action and cognitive control. Given that creativity is among the most extraordinary capacities of the human mind, one would think that our most highly prized piece of cortical real estate, the DLPFC, would need to run on all cylinders here. But this does not seem to be the case. Turns out, there is already a term for this phenomenon: Transient hypofrontality. It refers to the temporary downregulation of hyper-analytical and metacognitive processes which – oftentimes needlessly – limit the solutions space in a creative endeavor. With these toned down, more remote associations can occur. Importantly, this new experiment confirms this hypothesis. In addition, it shows that the heightened activation in the medial prefrontal cortex is accompanied by similar increases in activation in language areas (around the lateral fissure), the amygdala and the cingulate motor cortex, all of which form a network in which freestyle artistic expression may unfold."
