Hungry fruit flies can be trained by exposing them to two chemical odorants, one paired with the opportunity to feed on 1 M sucrose. On later testing, when given a choice between odorants the flies migrate specifically toward the sucrose-paired odor. This appetitively reinforced learning by the flies is similar in strength and character to previously(More)
The present study demonstrates that the primary somatosensory cortex of the rat contains a map of the entire body surface that is discernible with a routine anatomical staining technique, the succinic dehydrogenase reaction. The overall proportions of this map are relatively constant from rat to rat and very similar to those reported in previous(More)
We placed discrete injections of HRP into the somatosensory cortex of the rat on the day of birth and found discrete, ordered patterns of retrogradely labelled cells in the ventral posterior nucleus. We interpret these results as suggesting that topographic relations between thalamus and cortex develop independently of the periphery.
BACKGROUND Species-specific reference intervals for laboratory tests are required for diagnosis and management of disease. Few reports of reference intervals for biochemical analytes and protein fractions are available for alpacas. OBJECTIVES The aims of this study were to establish reference intervals for biochemical analytes measured in both serum and(More)
OBJECTIVE To investigate the effect of opsonization of Rhodococcus equi with R. equi-specific antibodies in plasma on bacterial viability and phagocyte activation in a cell culture model of infection. SAMPLE Neutrophils and monocyte-derived macrophages from 6 healthy 1-week-old foals and 1 adult horse. PROCEDURES Foal and adult horse phagocytes were(More)
BACKGROUND Species-specific reference intervals are needed for interpretation of laboratory tests. Reference interval studies of alpacas have been limited by low numbers and use of outdated methods. OBJECTIVES The aims of this study were to establish reference intervals for hematologic and coagulation tests in alpacas using a laser-based hematology(More)
OBJECTIVE To describe clinical signs and treatment outcomes for juvenile alpacas with spiral colon impaction (SCI). DESIGN Retrospective case series. Animals-12 juvenile (< 6 months old) camelids with SCI. PROCEDURES Crias with SCI were identified by searching the medical records database of the Cornell University Equine and Farm Animal Hospital.
