More on the brain. And my random notes…
- you use all of your brain, at different times (not just 10%)
- nerve cells are the basic building block of the brain
- nerve cells (neurons) generate electrical signals (action potentials) which allow them to transmit information over long distances
- glial cells (glia) are essential to nervous system function, though mostly their job consists of supporting neurons
- we don’t really know how many brain cells we have
- we can never really determine what is going on in someone’s head (only he or she can)
- left brain controls right side of the body, right brain controls the left, but logic and creativity stem from both hemispheres
- 1/4 of our brain is connected to our visual perception (can we really know this? i don’t believe so)
- the visual system is understood better than any other sensory system
I draw Eddie.
I consider the sub-conscious (the unconscious) as I collage a brain, using a city map of El Paso, Texas, into the composition. I focus in on the general vicinity where Eddie spends much of his youth (Sunset Heights). I choose the ground work to place into his mind/brain. The truth is Eddie could (probably would) choose differently and it might not be the city in which he grew up. It could be something that connects to a particular person, place or thing I know nothing about.
I like how the collage map compositionally sets the 1-10 highway to run from the eye-ball to the back of the brain (occipital lobe). See the red ↓ line, it follows the path of the real optic nerve. I don’t plan this. How does brain science explain serendipity?
This week I listen to Charlie Rose’s The Brain Series. While working on this drawing I listen to The Acting Brain.
- The acting brain devoted to movement (the motor system) needs a visual (internal representation) of the outside world (a particular act). The motor system begins with this internal representation. In order to act (to move) one (the brain) needs to know where to move. It needs a plan, a decision, a want, as well as a willingness to execute the plan. There is a whole hierarchy of function that must occur in order for one…to act/to direct action/to move (sounds to me like goal setting).
- The (entire) brain is set up for movement. Really…the entire brain? Did I hear this right? Do I understand correctly?
I meet Eddie in a ceramic art class in high school. He enjoys careful forming, making and perfecting objects with clay. Between the desire to create, a mechanically inclined and practical sensibility (logic meeting creativity), it’s no wonder he ends up in the engineering field. He (brain and mind) thrives on solving a problem. You understand I draw a conclusion here because only he can say for sure what is true.
