Brain Size

Brain size is one aspect of animal anatomy and evolution. Both overall brain size and the size of substructures have been analysed, and the question of links between size and functioning - particularly intelligence - has often proved controversial. Brain size is sometimes measured by weight and sometimes by volume (via MRI scans or by skull volume).

Famous quotes containing the words brain and/or size:

    Men should not labor foolishly like brutes, but the brain and the body should always, or as much as possible, work and rest together, and then the work will be of such a kind that when the body is hungry the brain will be hungry also, and the same food will suffice for both; otherwise the food which repairs the waste energy of the overwrought body will oppress the sedentary brain, and the degenerate scholar will come to esteem all food vulgar, and all getting a living drudgery.
    Henry David Thoreau (1817–1862)

    Great causes are never tried on their merits; but the cause is reduced to particulars to suit the size of the partizans, and the contention is ever hottest on minor matters.
    Ralph Waldo Emerson (1803–1882)
