Anything that happens in the brain is a brain event. While clearly a kind of physical event, some philosophers, when they discuss the mind-body problem, argue that some (certainly not all) brain events are also mental events.
Rather, students can be very creative, building models of the brain or a neuron using a variety of media, such as clay, playdough, and recyclable materials.
The number of cells that provide support to the brain, called glial cells, is estimated to be 10 to 50 times the number of neurons.
As the end of the Decade of the Brain quickly approaches, there is still much work for neuroscientists, and many questions about the brain remain unanswered.
The mind does not cause brainevents per se, rather the mind tells us why the brain is limited in carrying out X instead of Y or Z. I argue that the "mind" of the individual is akin to a mathematical attractor that identifies and restricts the probable behavior and decisions of that individual.
The mind's causal influence on the brain is as a distal cause (i.e., ultimate cause) whereby any physical cause for a brainevent must reference a higher level of organization (i.e., the mind).
Events that occur at the physical level (of the brain) are explained in geometrical language of the mind, and without this "language" there cannot be an explanation for many of the physical events that happen in the brain.
