Kallmann syndrome: MRI findings

Indian Journal of Endocrinology and Metabolism, 2013
Kallmann syndrome (KS) is a disease clinically characterized by the association of hypogonadotrophic hypogonadism and anosmia or hyposmia. It is a neuronal migration disorder.

Oscillatory Sequences of Firing in the Locust Olfactory System: Mechanisms and Functional Significance [PDF]

, 1999
What neural codes does the brain use to represent and process sensory information? Stimulus-evoked oscillatory synchronization of neuronal activity has been observed in many systems, yet the possible functions of such rhythmic synchronization in neural ...

Olfactory Tuft Cells Are Critical to Basal Inflammation, Innate Immune Response to Viral Infection, and Modulation of Quiescent Stem Cell Activation, Proliferation and Differentiation. [PDF]

Cell Prolif
Olfactory tuft cells communicate with other mucosal cells in maintaining olfactory epithelial immunity and sensory function. Disruption of tuft cell signalling pathways causes a skewed immune response, leading to heightened inflammation and increased activation of the quiescent stem cells, which are further exacerbated by viral infection.

Chromogranin A in the olfactory system of the rat [PDF]

, 1990
The olfactory bulb of the rat contains chromogranin A at a similar level as the adrenal gland or the hypophysis as revealed by immunoblots. Olfactory chromogranin A also displays the same size as chromogranin A of endocrine cells.

Distribution and densitometry mapping of L1-CAM Immunoreactivity in the adult mouse brain – light microscopic observation

BMC Neuroscience, 2003
Background The importance of L1 expression in the matured brain is suggested by physiological and behavioral studies showing that L1 is related to hippocampal plasticity and fear conditioning.

Assessment of olfactory nerve by SPECT-MRI image with nasal thallium-201 administration in patients with olfactory impairments in comparison to healthy volunteers. [PDF]

PLoS ONE, 2013
PURPOSE: The aim of this study was to assess whether migration of thallium-201 ((201)Tl) to the olfactory bulb were reduced in patients with olfactory impairments in comparison to healthy volunteers after nasal administration of (201)Tl.

Predicting olfactory receptor neuron responses from odorant structure [PDF]

, 2007
Background Olfactory receptors work at the interface between the chemical world of volatile molecules and the perception of scent in the brain. Their main purpose is to translate chemical space into information that can be processed by neural circuits ...

The source of spontaneous activity in the main olfactory bulb of the rat. [PDF]

PLoS ONE, 2011
In vivo, most neurons in the main olfactory bulb exhibit robust spontaneous activity. This paper tests the hypothesis that spontaneous activity in olfactory receptor neurons drives much of the spontaneous activity in mitral and tufted cells via ...

Enhanced odor discrimination and impaired olfactory memory by spatially controlled switch of AMPA receptors [PDF]

, 2005
Genetic perturbations of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate receptors (AMPARs) are widely used to dissect molecular mechanisms of sensory coding, learning, and memory.
