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 ...

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.

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.

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.

The olfactory bulb is the primary center for transmission of olfactory information to the vertebrate brain. Its functions are (1) to receive and process the information from the olfactory receptor neurons, (2) to send this information to different parts of the olfactory cortex in the forebrain, and (3) to provide for integration and modulation of the ...

Olfactory nerves and their excitatory action in the olfactory bulb
Experimental Brain Research, 1972Extracellular field potentials were recorded from the rabbit olfactory bulb following stimulation of the surface and the lateral olfactory tract. Experiments were also performed on olfactory nerve rootlets and a conduction velocity of .34 m/sec and an absolute refractory period of 2.7 msec were obtained.

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 ...

Electrical signaling in the olfactory bulb
Current Opinion in Neurobiology, 2003The olfactory bulb employs lateral and feedback inhibitory pathways to distribute odor information across parallel assemblies of mitral and granule cells. The pathways involve dendritic action potentials that can interact with a variety of voltage-dependent conductances and synaptic transmission to produce complex and dynamic patterns of activity ...

The ultrastructure of the cat olfactory bulb
Journal of Comparative Neurology, 1973AbstractThe fine structure of the olfactory bulb was investigated in the cat. Five types of bulbar neurons were identified on the basis of size, location, cytoplasmic organelles and synaptic complexes with the neuron perikaryon. The smallest diameter neurons were predominatly located in the glomerular and granule cell layers.
