The olfactory tubercle of the cat II. Immunohistochemical compartmentation
Experimental Brain Research, 1986In this study immunohistochemistry is used to investigate the distribution of opioid peptides, substance P (SP), neuropeptide Y (NPY) and acetylcholine (ChAT) in the olfactory tubercle (OT) of the cat. On the basis of our histochemical findings we divide the OT into two parts: the cortical part and the cap regions, the latter containing the granule ...

The olfactory tubercle of the cat I. Morphological components
Experimental Brain Research, 1986On the basis of morphology and arrangement of cell types, the olfactory tubercle (OT) of the cat is divided into two main components: a cortical part and the cap/hilus regions in which cortical characteristics are not recognizable. The cortical part undergoes a gradual transformation from a more cortex-like structure in the lateral half of the OT ...

Serotonin modulates glutamatergic transmission in the rat olfactory tubercle
European Journal of Neuroscience, 2010AbstractThe olfactory tubercle (OT) is found in the brains of mammals that are highly dependent on their sense of smell. Its human analogue is the poorly understood anterior perforated substance. Previous work on rat brain slices identified two types of field potential responses from the OT.

Cyto- and Chemoarchitecture of the Monotreme Olfactory Tubercle
Brain, Behavior and Evolution, 2006This study was undertaken to determine whether the olfactory tubercles of two monotremes (platypus and echidna) showed cyto- or chemoarchitectural differences from the tubercles of therian mammals. Nissl staining was applied in conjunction with enzyme reactivity for NADPH diaphorase and acetylcholinesterase, and immunoreactivity for calcium binding ...

Journal of Comparative Neurology, 1980
AbstractThe organization of the projection of olfactory bulb output cells was studied in the rat by injection of horseradish peroxidase (HRP) into the piriform cortex or olfactory tubercle. We made single HRP injections into small cuts in the fiber layer of the projection areas in order to enhance uptake by axons and to confine the region of HRP uptake.

Retinal projection to the olfactory tubercle and basal telencephalon in primates
Journal of Comparative Neurology, 1993AbstractThe retinal projection to the basal telencephalon was studied in eight species of primates from the suborders Strepsirhini and Haplorhini, including one anthropoid primate, the gibbon. Animals received an intraocular injection of tritiated amino acids and the distribution of retinal fibers and terminals was demonstrated by autoradiographic ...

Neurogenesis in the olfactory tubercle and islands of Calleja in the rat
International Journal of Developmental Neuroscience, 1985AbstractNeurogenesis in the rat olfactory tubercle and islands of Calleja was examined with [3H]thymidine autoradiography. Animals in the prenatal groups were the offspring of pregnant females given an injection of [3H]thymidine on two consecutive gestational days.

Behavioral Asymmetries Following Olfactory Tubercle Lesions in Cats
Brain, Behavior and Evolution, 200813 of 17 cats which received unilateral olfactory tubercle lesions exhibited contralateral sensory inattention and ipsilateral circling and hyperresponsiveness. The possible neural substrates involved in these asymmetries are discussed, including ascending amine systems and ascending and descending connections with the orbital cortex.

Localization of Choline Acetyltransferase in Laminae of the Rat Olfactory Tubercle
Journal of Neurochemistry, 1983Abstract: We report the distribution of choline acetyltransferase (ChAT) activity in the laminae of the rat olfactory tubercle. Within its posterior medial portion, the tubercle contains three parallel histological laminae that can be separated by cutting tangential sections from frozen tissue. ChAT was measured in homogenates of consecutive sections (

Piriform Cortex and Olfactory Tubercle
2014This chapter describes perspectives on the possible functional logic of neuronal circuits in the central olfactory system. The central olfactory system has multiplex pathways and loops that connect the olfactory bulb, olfactory cortex, neocortex, thalamus, ventral striatum, amygdala, hippocampus, and hypothalamus.
