Not illustrated. 1909 edition. Excerpt: ... tract of the fillet take a different course, being continued upwards, at first in the ventral part, but subsequently in the dorsolateral part of the tegmentum as the upper or main fillet; some of the fibres become lost in the tegmentum, and the rest are not traceable farther as a distinct bundle. But many fibres of this portion pass to the superior corpora quadrigemina, and others extend beyond the quadrigeminal region to the thalamic region (Flechsig). The lateral fillet is the continuation upwards of the central auditory path, mainly from the opposite cochlear nuclei, through the trapezium; the upper fillet is derived chiefly from the interolivary tract of the medulla oblongata--i.e. from the nucleus gracilis and nucleus cuneatus of the opposite side, reinforced by fibres from various sources (see p. 161 and fig. 175), and is the continuation of the sensory path of the posterior columns of the cord. Lying on the mesial side of the upper fillet, and apparently forming a portion of the same tract, is a bundle of fibres which differ from those of the true fillet in having a descending course. They originate in cells of the thalamus, enter the crusta at its mesial part, leave this to join the fillet, and run down as far as the formatio reticularis of the medulla oblongata. They form a thalamobidbar tract, and were formerly known as the mesial fillet, a term which has also sometimes been applied to the main or upper fillet. More or less intermingled with them are some fibres which are said to originate in the cortex cerebri and to leave the other fibres of the pyramid-tract in the crusta in order to enter this mesial part of the fillet and eventually to end in the formatio reticularis of the pons and medulla oblongata (cortico-bulbar...
