There are more connections in one human brain than there are galaxies in the known universe. Each human brain has trillions of electro-chemical connections in its neural network (while the galactic count still numbers only in the billions). Moreover, the structure of these networks is set up so that there are specific regions handling different functions. Generally speaking, the hippocampus is known to be the center for declarative memory (being able to recall specific information, versus procedural memory, which is more a form of conditioning), while the amygdala regulates emotion. The question that continues to baffle scientists and philosophers alike is this: What is the relationship between the physical brain and the conscious mind? “The external physical causes of such experiences, the behavioral responses associated with them, or the neural impulses in the brain…seem to be only accidentally connected with the experiences themselves.” The qualia, or basic sensory components of an experience, are what we use to define our perceptions. The way we see, feel, or hear our surrounding environment is subjective and different for every person.
