Frontiers of Science Summary
1) Music has been ubiquitous in human societies throughout the world since the
dawn of culture. Appreciation for music appears to be innate; infant as young as
two months will turn toward pleasant sounds
Action potential (a brief reversal of a membrane charge that moves down the axon, causing an electrical impulse to be transmitted) In
the brain, sight and sound are both represented by action potentials.
The information comes in on the dendrite (the recep
The Brain Basics
The brain is surprisingly small, and weighs only about 2% of the body weight; it requires 10% of blood flow and 20% of oxygen consumption.
Brain come in two halves: left and right hemisphere; in general most functions are duplicated on th

What is climate? How does it change?
Climate refers to time and space patterns of precipitation, temperature, and wind.
Climate (not weather) refers to the aggregate weather of a region over long intervals of
time; we cannot see it by looking at oddities
