The means by which the neurons are united in the 

 brain has long been known to minute anatomists; and 

 during the last fifteen years numerous investigators have 

 described the amazing networks which they form in the 

 cortex of the cerebrum. Whether or not the microscopic 

 fibrils coalesce end by end and become continuous from 

 cell to cell, has been a subject of controversy backed by 

 what has seemed evidence on both sides. The contention 

 that the neurons are directly united by their filaments, 

 has not been demonstrated beyond question, the facts 

 going to show that these extended, delicate processes of 

 the cells very closely approach each other and, during the 

 elate, erectile condition of diurnal wakefulness, actually 

 touch; and that in sleep this contact is broken, a condi- 

 tion of non-contiguity, brought about in part by the 

 shrinking away of the blood capillary system in the 

 cortex during somnolence.
