    Abstract:
    Characteristics of a ventral tract from the bed nucleus of the stria terminalis (BST) to the amygdaloid complex in the monkey (Macaca fascicularis) are described. A system of approximately 200 fiber bundles lying between the BST and baso-lateral part of the amygdaloid complex was identified and postulated to be monosynaptic. The bundles consist of unmyelinated fibers with a median diameter of .16-.20 mcm. No axons could be found with a diameter greater than .55 mcm, and 8% of the fibers had a diameter of less than .10 mcm. The total number of axons in the tract was calculated to be 500,000. It is concluded that the direction of conduction in this pathway is from BST to the amygdala, and, since the neurones of BST contain estradiol, that this tract may be involved in the regulation of ovulation.
