Tonic hypnogenic effect of the olfactory tubercle
Experimental Neurology, 1980Abstract We randomly stimulated the olfactory tubercle in chronically prepared cats and found their time in wakefulness was decreased. Lesions in this region suppressed primarily slow-wave sleep.

Radial glial cells in the postnatal olfactory tubercle of hamsters
Developmental Brain Research, 1982 Abstract A discrete population of radial glial cells whose fibers extend into the lateral part of the olfactory tubercle can be labeled with horseradish peroxidase (HRP) during the first week of postnatal life. Radial glial processes are also seen in electron micrographs of this region in young animals and appear to form guides for longitudinally ...

Locus coeruleus influences upon the olfactory tubercle
Brain Research Bulletin, 1980Locus coeruleus (LC) influences upon the olfactory tubercle (OT) were studied. Evoked potentials and unit activity recording techniques were used as well as the horseradish peroxidase (HRP) labelling method. A biphasic potential was recorded in cat's OT following a single pulse delivered to the LC.

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 ...

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 ...

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 ...

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.

Nucleus of the tractus solitarius projections to the olfactory tubercle: An HRP study
Brain Research Bulletin, 1987Labelled cells were found in the nucleus of the tractus solitarius (NTS) after horseradish peroxidase injections in the olfactory tubercle (OT) of the rat. These results suggest a direct pathway from the NTS to the OT. The importance of this pathway in a neural circuit related to autonomic functions is discussed.

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 ...

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.
