myelinated nerve cell bodies in the dorsal horn of the monkey (saimiri sciureus).while observing electronmicroscopic preparations of laminae i-iii of rexed ('52), taken from the lumbosacral region of squirrel monkey spinal cord, several small neuronal cell bodies were found which were partially or completely encircled by compact myelin sheaths of varying thickness. though found in all three laminae, the occurrence of these perikaryal sheaths was less frequent in the "inner zone" of lamina ii where there were few myelinated fibers. perikaryal profiles which were completely su ...1976823813
the squirrel monkey entorhinal cortex: architecture and medial frontal afferents.the cytoarchitecture of the periallocortex was studied in cresyl-violet-stained frontal and sagittal sections in six adult squirrel monkeys (saimiri sciureus). the entorhinal area, located between the sulcus semiannularis and sulcus rhinalis in the rostral parahippocampal gyrus, has been divided into a caudal-medial area 28a and rostral-lateral area 28b. of the six paleocortical laminae, layer ii is the most distinctive, for in 28a it consists of a deeply-stained, dense, continuous lamina and in ...1976824031
naturally occurring tuberculosis in a squirrel monkey and a cebus monkey.tuberculosis was detected in a brazilian squirrel monkey (saimiri sciureus) and in a cebus monkey (cebus apella). both of these animals were housed in the same room with a rhesus monkey (macaca mulatta) subsequently found to be tuberculous. all 3 of the monkeys died within a 4-month period.1976824261
physiology of peripheral neurons innervating otolith organs of the squirrel monkey. i. response to static tilts and to long-duration centrifugal force.1. the response to static tilts was studied in peripheral otolith neurons in the barbiturate-anesthetized squirrel monkey (saimiri sciureus). each unit was characterized by a functional polarization vector, which defines the axis of greatest sensitivity. a circumstantial criterion was used to assign units to the inferior (in) or superior (sn) vestibular nerves. the former neurons should innervate the sacculus, the latter mainly the utriculus. confirming pasting experiments, the polarization vect ...1976824412
physiology of peripheral neurons innervating otolith organs of the squirrel monkey. ii. directional selectivity and force-response relations.1. the directional selectivity of peripheral otolith neurons was studied in the barbiturate-anesthetized squirrel monkey (saimiri sciureus). each unit's most sensitive axis was characterized by a functional polarization vector. the direction of a centrifugal force was varied with respect to the vector and to the macular plane. the neurons respond in an excitatory manner to shearing forces orthogonally disposed to the vector. the sensitivity to orthogonal shears was usually 10-15% of the sensitiv ...1976824413
physiology of peripheral neurons innervating otolith organs of the squirrel monkey. iii. response dynamics.1. the discharge of peripheral otolith neurons in response to sinusoidal force variations was investigated in the barbiturate-anesthetized squirrel monkey (saimiri sciureus). the sine waves were superimposed on a background force which biased the end organ so as to excite or inhibit the unit's firing. both regularly and irregularly discharging neurons were studied. 2. the response amplitude, measured as a peak-to-peak changes in firing rate, reached near-maximal values during the first sine-wave ...1976824414
temperate season outdoor housing of saimiri sciureus in the northern united states.this study demonstrates the ability of saimiri to adapt to out-of-door housing in a northern temperate climate from may through october, to ovulate (both naturally and in response to an induction regime), become pregnant, give birth, and to initiate lactation. the observations reported are of importance for the captive breeding of saimiri for use in biomedical research.1976826633
hematological development of the infant squirrel monkey (saimiri sciureus).hematologic developmental norms from infant squirrel monkeys indicate a relative maturation of the hematopoietic system by 16 weeks. the elevated hemoglobin, hematocrit, red blood cell count, mcv and mch at birth are followed by a decreasing hemoglobin (decreasing red blood cell count and mcv) until 4 weeks of age. a reticulocytosis then occurs until the hemoglobin level approximates adult concentrations by 16 weeks of age with gradual changes in this as well as hematocrit, red blood cell count, ...1976827482
