The motor cells of this middle level also discharge into the motor mechanisms of the lowest level. Jackson located these middle level structures in the cortex of the central convolutions, the basal ganglia and the centers of the special senses in the cortex.

Now, it was the morning of the fourth day, and lo! at the first leap of the sun of that day the flame of the Identical abated in its fierceness, and it dwindled and darkened, and tapered and flickered feebly, descending from its altitude in the heavens and through the ceiling of the Hall, and lay down to sleep among the intricate lengths and frizzled convolutions and undulating weights flowing from Shagpat, an undistinguished hair, even as the common hairs of his head.

The prime perceivable difference between our brains and those of the Apes and lower animals is the larger number of enfoldments, or convolutions, that are developed by the Human.

These now helped to enhance the wild aspect of the wreck, for iron girders had been twisted by the action of fire into snake-like convolutions in some places, while, in others, their ends stuck out fantastically from the blackened walls.

The monument is a somewhat elaborate white marble tablet with a plump cherub on guard, and with many of the scrolls and convolutions typical of the Carolean and later Jacobean taste. This monument was removed to the north wall of the nave two centuries later, in 1885, when the church was restored, to allow of access to the new vestry then added.

If your mind has the right formation, if your brain is provided with the deep convolutions, and good luck has supplied you with a good education in youth, the whole thing is dependent on your health on your liver, your stomach, or some other part of your internal machinery. Very often your success is dependent on your temper and tact. These depend on your digestion.

But by hard-headed persons I mean those beyond the ordinary, those so far gone that a pin-prick through the skull would yield not so much as a drop of ooze; persons whose brain convolutions did they appear in fright at the aperture on the insertion of the pin like a head at a window when there is a fire on the street would betray themselves as but a kind of cordage.

It is composed of both white and gray matter. The former comprises the greater part of the mass, while the latter is spread over the surface in a layer of about 1/8 of an inch thick. The gray matter is the portion having the highest functions, and its apparent quantity is largely increased by being formed in convolutions.
