In I of the Vortex , Rodolfo Llinas, a founding father of modern brain science, presents an original view of the evolution and nature of mind. According to Llinas, the "mindness state" evolved to allow predictive interactions between mobile creatures and their environment. He illustrates the early evolution of mind through a primitive animal called the "sea squirt." The mobile larval form has a brainlike ganglion that receives sensory information about the surrounding environment. As an adult, the sea squirt attaches itself to a stationary object and then digests most of its own brain. This suggests that the nervous system evolved to allow active movement in animals. To move through the environment safely, a creature must anticipate the outcome of each movement on the basis of incoming sensory data. Thus the capacity to predict is most likely the ultimate brain function. One could even say that Self is the centralization of prediction.At the heart of Llinas's theory is the concept of oscillation. Many neurons possess electrical activity, manifested as oscillating variations in the minute voltages across the cell membrane. On the crests of these oscillations occur larger electrical events that are the basis for neuron-to-neuron communication. Like cicadas chirping in unison, a group of neurons oscillating in phase can resonate with a distant group of neurons. This simultaneity of neuronal activity is the neurobiological root of cognition. Although the internal state that we call the mind is guided by the senses, it is also generated by the oscillations within the brain. Thus, in a certain sense, one could say that reality is not all "out there," but is a kind of virtual reality.

Rodolfo Llinás aborda el cerebro a través de una lente evolutiva, postulando que el desarrollo del cerebro fue impulsado fundamentalmente por la necesidad de los organismos de navegar e interactuar activamente con su entorno. Su extensa investigación profundiza en áreas cruciales como el cerebelo y el tálamo, descubriendo los intrincados mecanismos de la comunicación neuronal. Llinás explora además las implicaciones funcionales de estos complejos sistemas, abordando consecuencias más amplias para nuestra comprensión de la cognición y el comportamiento humanos. Su trabajo ofrece una perspectiva fascinante sobre la interacción entre las presiones evolutivas y la organización estructural y funcional del cerebro.
