The grey cortex con- sists, according to Mey- nert, of the following layers (Fig. 92) :—(1) a superficial layer of grey Fig. 92. — Vertical Section through the Grey Matter of a Cerebral Convolution. a, Superficial layer; 6, closely- packed small ganglion cells ; c, the . layer of the cornu Ammonis, this being the principal layer; d, the " granular formation," small multipolar ganglion cells; e, the layer of spindle-shaped ganglion cells.
