Effects of dopamine and norepinephrine on neuronal activity of the olfactory tubercle
Brain Research Bulletin, 1985The effects of iontophoretic administration of norepinephrine (NE) and dopamine (DA) on olfactory tubercle (OT) neurons that respond to lateral hypothalamus (LH) or locus coeruleus (LC) electrical stimulation were studied. NE and DA decreased the frequency of OT neurons which were increased or decreased by the LH stimulation.

Sleep elicited by olfactory tubercle stimulation and the effect of atropine
Behavioural Brain Research, 1981The effects of high-frequency olfactory tubercle (TbOf) stimulations were studied on the EEG and behaviour of freely-moving cats. The results were as follows: (1) TbOf stimulation elicited sleep similar in every respect to physiological sleep; (2) statistical evaluation of the results showed that primarily the appearance and maintenance of slow wave ...

Effects of Locus Ceruleus and Olfactory Bulb Stimulation on Rat Olfactory Tubercle Neuron Activity
Otolaryngology–Head and Neck Surgery, 1988The effects of electrical stimulation of the olfactory bulb and the locus ceruleus on olfactory tubercle neurons were examined in rat models. Ipsilateral stimulation of the olfactory bulb produced excitation in 31% of olfactory tubercle neurons tested and inhibition in 17%.

Differential projections from locus coeruleus to olfactory bulb and olfactory tubercle: An HRP study
Brain Research Bulletin, 1982The microiontophoretic administration of horseradish peroxidase (HRP) to the olfactory bulb (OB) or olfactory tubercle (OT) in cats and rats yielded similar results in both species. After an OB HRP-injection ipsilateral and contralateral labelled neurons were seen in the piriform cortex, polymorphic layer of OT, magnocellular preoptic region, lateral ...

[Transmitter histochemistry of the olfactory tubercle in the rat].
Journal fur Hirnforschung, 1983The tuberculum olfactorium of the adult rat was investigated by means of neurohistological, fluorescence histochemical and enzyme histochemical methods. Using the rapid Golgi impregnation technique, seven neuron types could be demonstrated which can clearly be differentiated according to morphological criteria.

Olfactory tubercle's different neural elements activated by locus coeruleus
Brain Research Bulletin, 1981Olfactory tubercle (OT) evoked potentials were recorded following single pulse stimulation of the locus coeruleus (LC) in cats. Also, OT unit responses were recorded extracellularly following LC repetitive stimulation in rats. In order to characterize the properties of OT evoked potentials, these responses were evaluated following repetitive ...

Granule cells of the olfactory tubercle and the question of the islands of calleja
Journal of Comparative Neurology, 1987AbstractThe granule cell clusters in the rat olfactory tubercle were studied in Nissl‐stained and Golgi‐impregnated sections. Discrete cell clusters that vary in size and shape occur mainly in the multiform layer and less often in the molecular layer.

Projections from the Ventral Tegmental Area to the Olfactory Tubercle in the Rat
Otolaryngology–Head and Neck Surgery, 1987The projection between the ventral tegmental area (VTA) and the olfactory tubercle (OT) was examined electrophysiologically in the rat. Stimulation of the olfactory bulb (OB) determined if the OT neurons were olfactory‐related. Ipsilateral VTA stimulation produced a change in neuronal activity in 77% of the neurons tested, with 41% being inhibited, 24%

Aggression-associated changes in murine olfactory tubercle bioamines
Brain Research, 2003The relationship between changes in regional brain bioamine levels and the expression of intraspecies aggressive behavior was evaluated in two murine models. In one study, normal male mice were maintained either in aggregate (i.e., normal, intraspecies social behavioral controls) or isolated (i.e., developed, non-social intraspecies aggressive 'fighter'

On the presence of a peculiar alpha rhythm in the olfactory tubercle of waking armadillos
Electroencephalography and Clinical Neurophysiology, 1987A very regular 8-12 rhythm was found in the olfactory tubercle of the armadillo Chaetophractus villosus. The rhythm was observed during wakefulness. Considerable sinusoidal activity was also observed not only during wakefulness, but during synchronized (slow) and desynchronized (paradoxical) sleep.
