    The brain soup: drugs and diets

    July 29, 2017

    “Imagine for a moment that we are nothing but the product of billions of years of molecules coming together and ratcheting up through natural selection, that we are composed only of highways of fluids and chemicals sliding along roadways within billions of dancing cells, that trillions of synaptic conversations hum in parallel, that this vast egglike fabric of micron-thin circuitry runs algorithms undreamt of in modern science, and that these neural programs give rise to our decision making, loves, desires, fears, and aspirations.” -  David Eagleman

    In the previous articles , we discussed the main ingredients of the human brain and how they work together in broad strokes. This was due to both the complexity of the topic and the fact that we do not know better yet. Despite great advances in neuroscience during the last century, it is safe to say we are still only scratching the surface, and it is important to keep this in mind when we start discussing the effects of drugs and diets on brain function.

    This article attempts to explain how external molecules interact with our brain physiology in such profound ways as to change how we process information, the decisions we make, and the feelings inside us. If the explanations seem vague or the examples too circumspect, it is because they are. The best we can say as of now is that drugs and diets change brain neurochemistry. Their mechanisms and the full extent of its effects, however, remain largely obscure.
