The mammalian olfactory system has an amazing ability to distinguish thousands of odorant molecules at the trace level. Scientists have made great achievements on revealing the olfactory sensing mechanisms in decades; even though many issues need ...

Background: The olfactory bulb is one of the first regions of insult in Parkinson’s disease (PD), consistent with the early onset of olfactory dysfunction. Investigations of the olfactory bulb may, therefore, help early pre-motor diagnosis.

Nicotinic cholinergic regulation of olfactory bulb blood flow response in aged rats
In our previous research, we had demonstrated the crucial role of neuronal nicotinic acetylcholine receptors (nAChRs) in potentiation of the olfactory bulb blood flow response to olfactory stimulation in adult rats. The present study examined the effects

Olfactory neurogenesis and its role in fear memory modulation
Olfaction is a critical sense that allows animals to navigate and understand their environment. In mammals, the critical brain structure to receive and process olfactory information is the olfactory bulb, a structure characterized by a laminated pattern ...

This study describes the microscopic organization of a wedge-shaped area at the intersection of the main and accessory olfactory bulbs, or olfactory limbus , and an additional component of the anterior olfactory nucleus or alpha accessory olfactory bulb ...

Mechanisms of pattern processing in olfactory bulb-like circuits [PDF]
The scope of brain research spans several orders of magnitude ranging from small groups of amino acid residues in ion channels to fMRI signals reflecting activity averaged over thousands of neurones. From a theoreticians point of view very interesting

Connectivity and dynamics in the olfactory bulb [PDF]
Dendrodendritic interactions between excitatory mitral cells and inhibitory granule cells in the olfactory bulb create a dense interaction network, reorganizing sensory representations of odors and, consequently, perception. Large-scale computational models are needed for revealing how the collective behavior of this network emerges from its global ...

Dopaminergic modulation of odor responses by local interneurons in the olfactory bulb [PDF]
The olfactory bulb is one of the few regions in the brain where dopamine is provided locally by an intrinsic population of GABAergic interneurons but their role in processing of sensory information remains ambiguous.

Topological reorganization of odor representations in the olfactory bulb. [PDF]
Odors are initially represented in the olfactory bulb (OB) by patterns of sensory input across the array of glomeruli. Although activated glomeruli are often widely distributed, glomeruli responding to stimuli sharing molecular features tend to be ...

Optophysiological analysis of pattern classification strategies in the zebrafish olfactory bulb [PDF]
Classification of overlapping activity patterns is a common problem for sensory systems. For a robust representation of sensory stimuli, neuronal circuits should generalize over input patterns reflecting variations of the same stimulus but separate ...
