Caffeine and the olfactory bulb
Molecular Neurobiology, 1997Caffeine, a popular CNS stimulant, is the most widely used neuroactive drug. Present in coffee, tea, chocolate, and soft drinks as well as over-the-counter and prescription medications, it influences millions of users. This agent has achieved recent notoriety because its dependency consequences and addictive potential have been re-examined and ...

Olfactory bulb transplantation into the olfactory bulb of neonatal rats: an autoradiographic study
Brain Research, 1991Tritiated thymidine prelabeled presumptive olfactory bulbs (E15-E17, and E19) were homotopically transplanted in unilaterally partially or totally bulbectomized neonatal rats (P1-P5). [3H]thymidine was injected to pregnant rats at the time when the large neurons of the bulb were undergoing cellular division.

Olfactory Bulb Response of Rabbit
Science, 1961An approach to understanding the properties of dendrites is to record the response of the olfactory bulb where the dendrites of mitral cells form the glomeruli. After the stimulations of the bulb and nasal mucosa, the responses appear different, but they are fundamentally composed of three successive potentials, suggesting that the last one is the ...

The olfactory bulb is the site of the first synaptic processing of the olfactory input from the nose. It is present in all vertebrates (except cetaceans) and a the analogous antennal lobe in most invertebrates. With its sharply demarcated cell types and histological layers, and some well-studied synaptic interactions, it is one of the first and ...

Centrifugal Arousal in the Olfactory Bulb
Science, 1959The electrical activity of the olfactory bulb was recorded in awake, unrestrained cats with electrodes permanently implanted. It was found that any kind of sensory stimulation producing alertness or arousal brought about the appearance of bursts of rhythmic activity, the magnitude of which was related to the degree of alertness of the cat.

Projections of olfactory bulbs to the olfactory and vomeronasal cortices
NeuroReport, 2008Projections from the olfactory bulbs have been traditionally described as 'nontopographically organized'. Olfactory and vomeronasal projections have been reported to reach nonoverlapping cortical areas. Four receptor expression zones have been described in the olfactory epithelium, maintained in the main olfactory bulb, but none in the olfactory cortex.

The neuropil of the glomeruli of the olfactory bulb
Journal of Cell Science, 1971ABSTRACT The neuropil of the glomeruli of the rat olfactory bulb has been studied with the electron microscope with a view to elucidating the type of processes involved - dendrites, appendages and axons - their cellular identity, and the synaptic relationships they establish.

Chaos and learning in the olfactory bulb
International Journal of Intelligent Systems, 1995The olfactory system, and in particular its first relay center, the olfactory bulb (OB) is a ``working horse'' for investigating the structural conditions and functional significance of chaotic information processing in neural networks. Oscillatory activities were studied in the framework of a model based on the connections among oscillators formed by ...

Anatomy and Neurochemistry of the Olfactory Bulb
2003This chapter focuses on anatomical organization and neurotransmitters of the olfactory bulb, with an emphasis on afferent projections from brain sources. An overview of neuronal and molecular mechanisms underlying odor coding in the olfactory bulb is also provided. Most of the information comes from rodents; human data are presented, whenever possible.

Microglia and the developing olfactory bulb
Neuroscience, 1993The developmental appearance of microglia in the rat olfactory bulb was investigated through the use of selective staining with the B4-isolectin from Griffonia simplicifolia. No changes in the density or distribution of either the spherical, macrophage "ameboid" form or the highly arborized "ramified" variety of microglia were observed in the ...
