In neural network, potential for long-lasting modifications of functional characteristics is present. This capacity, known as neural plasticity, attracts attention of many neuroscientists. So there are numerous studies about the influence of pre- and postnatal experience on cellular differentiation and the formation of synaptic connexions as well as ...

Olfactory bulb transplantation into the olfactory bulb of neonatal rats
Brain Research, 1990Embryonic olfactory bulbs (E14-E18) were homotopically transplanted into neonatal rats (P1-P5) after partial or total bulb removal. After different survival times, the animals were sacrificed and their brains processed for histological and immunohistochemical observations.

Olfactory coding in the mammalian olfactory bulb
Brain Research Reviews, 2003There have been a number of recent approaches to the study of olfactory coding, each of which has its advantages and disadvantages. In the present review, we discuss our own work on this topic, which has involved mapping uptake of [14C]2-deoxyglucose across the entire glomerular layer of the rat main olfactory bulb in response to systematically ...

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 ...

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 ...

Neuropharmacology of the Olfactory Bulb
Current Molecular Pharmacology, 2008The olfactory bulb is located at the start of a hierarchical chain of sensory processing mechanisms. The relative ease of its isolation allows the possibility that models of these mechanisms might be integrated to develop a detailed understanding of function.

Olfactory bulb volume in smokers
Experimental Brain Research, 2012The study aimed to investigate the volume of the olfactory bulb in smokers. Specifically, we wanted to see whether environmental influences may exert a negative influence on OB structure. Twenty-one smokers and 59 non-smokers, matched for age and sex, underwent olfactory testing by means of the Sniffin' Sticks testing device (measurement of odor ...

The differential projections of the olfactory bulb and accessory olfactory bulb in mammals
Journal of Comparative Neurology, 1975AbstractThree species were studied, the rabbit, opossum and rat. Lesions of the main olfactory bulb caused terminal degeneration, assayed by the Fink‐Heimer method, to occur in the ipsilateral olfactory tubercle, prepyriform cortex (including its periamygdaloid part), ventrolateral entorhinal area, and in anterior and posterolateral divisions of the ...

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.

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 ...
