In a cubic millimeter of your brain, there are about 100,000 of these neurons and maybe a billion of those connections. But it's worse. So, if you could zoom in to a neuron, and, of course, this is just our artist's rendition of it. What you would see are thousands and thousands of kinds of biomolecules, little nanoscale machines organized in complex, 3D patterns, and together they mediate those electrical pulses, those chemical exchanges that allow neurons to work together to generate things like thoughts and feelings and so forth.
En un milímetro cúbico del cerebro hay unas 100 000 neuronas y quizá mil millones de conexiones. Pero es peor. Si pudiéramos ampliar una neurona y, claro, esta es una interpretación artística, podríamos ver miles y miles de tipos de biomoléculas, pequeñas máquinas a escala nanométrica organizadas en patrones complejos, 3D, y juntas medirían esos pulsos eléctricos, esos intercambios químicos que les permiten a las neuronas trabajar juntas para generar pensamientos, sentimientos, etcétera.
