    We travel‚ initially‚ to lose ourselves; and we travel‚ next‚ to find ourselves. We travel to open our hearts and eyes and learn more about the world than our newspapers will accommodate. We travel to bring what little we can‚ in our ignorance and knowledge‚ to those parts of the globe whose riches are differently dispersed. And we travel‚ in essence‚ to become young fools again -- to slow time down and get taken in‚ and fall in love once more. The beauty of this whole process was best described

    Introduction Neurons (also known as neurons‚ nerve cells and nerve fibers) are electrically excitable and the most important cells in the nervous system that functions to process and transmit information. Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. It is primarily the surfaces of the dendrites that receive chemical messages from other neurons. One extension is different from all the others‚ and is called

    Chapter 2: Neurons and Glia 1. Introduction * Although there are many neurons in the human brain (about 100 billion)‚ glia outnumbers neurons by tenfold. 1:10 ratio. * Neurons are the most important cells for the unique functions of the brain. * Neurons sense changes in the environment‚ communicate these changes to other neurons‚ and command the body’s responses to these situations. * Glia‚ or glial cells‚ are thought to contribute to brain function mainly by insulating‚

    Speed of the Human Neural Impulse Helmholtz (1821-1894) was a German scientist. In 1850‚ he measured the neural impulse in frogs. By strapping down the frogs and putting electrical voltage into their legs‚ Helmholtz measured the time it took for the frogs’ leg to twitch. Helmholtz used a galvanometer to measure the neural impulse. He found that the neural impulse in frogs was 83-90 ft/s. Afterwards‚ Helmholtz went on to test the neural impulse in humans. He put a low grade electrical voltage to humans’

    speeds to operate at even at the simplest level. How do the biological tissues of our body support such rapid coordination of the brain‚ limbs‚ and sensory input? They do so with nervous system tissue that imitates electrical wiring. A series of photomicrographs and schematic illustrations show myelinated nerve fibers. Panel A is an illustration of a single neuron with major structures labeled. Panel B is an illustration of a cross section of a neuron that shows a myelin sheath wound around an axon
