The following is a sample of things written in my notebook last July either directly from or inspired by Jonah Lehrer's
Proust was a Neuroscientist, which, by the way, I highly recommend. (See also:
The big post of book recommendations.)
Next I will post squibs from or inspired by Twyla Tharp's
The Creative Habit.

Our brains have two separate lumps [hemispheres] that are designed to disagree with each other -- meaning every brain is crowded with at least two different minds. But instead of recognizing confusion, we weave it into a neat narrative.
Everything we see is an abstraction. Before we can make sense of our sensations, we have to impress our illusions upon them.
We cannot see how we see. E.g., we are blind to our own blind spot in the center of the visual field.
Brain cells are fascinated not by dots of light but by angles of lines.
'
Blindsight' patients are able to unconsciously see light, but are missing awareness; they are unable to consciously access what their brains know. As result, they "see" darkness.
The same thing we do with visual "understanding" -- filtering abstract pieces of light into a coherent illusion -- is probably very similar to what we do with other types of understanding. That is, we filter disparate (and often contradictory) data into a coherent story of how the world works.
The self emerges from chaos of consciousness -- "a kind of whole made of shivering fragmants."
Our identity is the most intimate thing we experience, and yet it emerges from a shutter of cellular electricity.
"The permanent-seeming self is actually an endless procession of disjointed moments. There is no single location in the brain where severed moments get reconciled; instead, the head holds a raucouss parliament of cells that endlessly debate what feelings and sensations should become conscious."
It is useful to remember that we start each day with a slightly new brain. "Each day we wake up slightly altered, and the person we were yesterday is dead." -John Updike
Memories require a transformative process; if you prevent a memory from changing, it literally ceases to exist. Therefore, we have to mis-remember something in order to remember it.
Memory is a ceaseless process, not a repository of inert information.
Any given experience can endure for about 10 seconds in short-term memory. After that, consciousness must begin anew.
The act of attention turns our sensory parts into a focused moment of consciousness. The fictional self is what binds those moments together.
