Van Gehuchten, A. Le corps restiforme et les connexions bulbo-cereb.elleuses. Le Nevraxe, Vol. 

 6, pp. 123-154. 1904. 



Van Gehuchten concludes from a series of observations upon the corpus 

 restiforme that it is composed exclusively of ascending fibers. The spinal com- 

 ponent arises from the column of Clarke. The bulbar portion consists of four 

 groups of fibers: "(l) Des fibres olivo-cerebelleuses croisees. (2) Des fibres 

 reticulo-cerebelleuses ventrales directes et croisees. (3) Des fibres reticulo-cere- 

 belleuses dorsales directes et croisees. (4) Des fibres nucleo-cerebelleuses egele- 

 ment directes et croisees." G. E. c.

All of the olfactory neurones of the second order send their axones into the t. 

 olfactorius lateralis. Only neurones of the third order are associated with the 

 anterior commissure. These connect the olfactory lobe of one side with the olfac- 

 tory bulb of the other side, and, therefore, do not form a true commissure. The 

 paper includes a review of literature and a report of degeneration experiments by 

 the author upon the olfactory bulb of the rabbit. G. E. c.

 1904. 



This paper is chiefly a critical review of recent observations by Held, Auer- 

 BACH, DoNAGGio, Bethe and Cajal. From his own observations van Gehuch- 

 ten agrees with Cajal that the nerve terminals end upon the cell by irregularly 

 shaped expansions. The pericellular net is formed of axone terminals

By the application of this method numerous gemmules are found upon the 

 nerve cells of the cerebellum, nucleus caudatus and spinal cord. G. E. c.

 Nevraxe, Vol. 6, pp. 201-216. 1904. 



With the exceptionally clear preparations which the method of Cajal gives 

 the author fails to find any fibrillae passing from one branch of the bifurcating fiber 

 directly to the other branch. Nor does he find any anastomoses of fibrillae at this 

 point. The fibrillae all pass into the cell body. Michote believes, therefore, that 

 the spinal ganglion cell is functionally concerned in conduction, and that the neuro- 

 fibrillae are the conducting elem.ents of the nerve. G. E. c.

The observation of the following structures is considered by the author of 

 especial importance: a non-medullated commissura septae, a fasciculus cortico-
