...whole brain looks like a dirty, wetted newspaper crumpled up and patted into somewhat the shape of a rounded bun. Another comparison might be to a lobsided mushroom, for the bottom of the brain runs into a sort of stalk, which is the spine...
...outer surface of the brain is grey in color. Here are the nerve cells which function in consciousness. One estimate counts 92,000,000 cells. A stimulus comes to one or more of these, and each affected cell stimulates ten of its neighbors (by this theory). Each of these ten stimulates a neighboring ten, and so on by geometrical proportion, until the influence of the original stimulus fades away. Such stimuli are normally brought to these cells in the grey cortex (bark) by the nerve fibres. These form the white core of the brain. (Naturally there are blood vessels...
Macroscopically (to the naked eye) the whole brain is divided crosswise into two unequal, grossly wrinkled parts. The rear and lower part is the cerebellum, the chief duty of which is to regulate the automatic reflexes and movements, such as walking. The upper and fore part is the cerebrum, where thinking is done. It is by far the larger...
...outer world, are carried by afferent nerves to definite lobes and to definite locations in these lobes. There the grey cells in the cortex mull the influences of these stimuli, play with them, sometimes bury them as memories. If a physical reaction is wanted, consciously or subconsciously, the brain sends out its will by way of efferent nerves to the organs of expression, to the limbs, the viscera, the tongue, the hand...
...locations of the brain functions in each lobe may be roughly placed as follows: At the forward end is the higher psychical centre, just back of the eyebrows and forehead, and running back to about the temples. An injury to an eye or a frontal sinus may puncture this centre, but is not always fatal. Somewhat higher up and a trifle before the temple is the speech centre. Just above that is that of the head. Ahead of the head centre is that of the eyes. Back of these latter two and going in a sort of band from...
