Journal of Neuroscience, 2019 In awake rodents, the neural representation of olfactory information in the olfactory bulb is largely dependent on brain state and behavioral context. Learning-modified neural plasticity has been observed in mitral/tufted cells, the main output neurons ...

A neuroimaging study of pleasant and unpleasant olfactory perceptions of virgin olive oil [PDF]
, 2016 Functional magnetic resonance imaging (fMRI) has been used to collect information from neurons that receive direct input from olfactory bulbs when subjects smell virgin olive oil. The pleasant aroma of three extra virgin olive oils (var.

Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background The loss of smell (anosmia) has been noted in numerous diseases, including COVID‐19. Inflammatory and microstructural alterations are possible underlying mechanisms of anosmia in COVID‐19. However, no atlas exists to study olfaction and the associated tissue property changes.

Convulsant actions of 4-aminopyridine on the guinea-pig olfactory cortex slice [PDF]
, 1982 The effects of bath-applied 4-aminopyridine on neurones and extracellular potassium and calcium concentrations were recorded in slices of guinea-pig olfactory cortex. Neurones were orthodromically activated by stimulating the lateral olfactory tract.

Is Dysphagia in Multiple System Atrophy Responsive to Levodopa? Results from a Retrospective Study
Movement Disorders Clinical Practice, EarlyView.Abstract Background Dysphagia remains a major clinical concern in multiple system atrophy (MSA), and so far, lacks relevant treatment options. Objective To systematically assess levodopa‐responsiveness of dysphagia in MSA. Methods 19 MSA‐patients underwent endoscopic swallowing evaluation in Off‐ and On‐state, following an adapted FEES‐levodopa‐test ...

Epilepsia, EarlyView.Abstract Objective Autoimmune encephalitis (AE) is characterized by inflammatory processes in the central nervous system and frequently presents with seizures. Even though an ictogenic potential has been shown for some antibodies against neuronal surface antigens (NSAbs), AE pathophysiology is complex, and NSAbs‐independent mechanisms are likely to ...

Broadcasting of Cortical Activity to the Olfactory Bulb
Cell Reports, 2015 Odor representations are initially formed in the olfactory bulb, which contains a topographic glomerular map of odor molecular features. The bulb transmits sensory information directly to piriform cortex, where it is encoded by distributed ensembles of ...

Spared piriform cortical single-unit odor processing and odor discrimination in the Tg2576 mouse model of Alzheimer's disease. [PDF]
PLoS ONE, 2014 Alzheimer's disease is a neurodegenerative disorder that is the most common cause of dementia in the elderly today. One of the earliest reported signs of Alzheimer's disease is olfactory dysfunction, which may manifest in a variety of ways.

Анналы клинической и экспериментальной неврологии, 2022 Introduction. The control of the survival and differentiation of immature neurons in the piriform cortex of rodents, which can transform into GABAergic and/or glutamatergic neurons under the influence of olfactory stimuli, is an important factor for ...

Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance In most primary sensory cortical areas, sensory information is topographically organized. The spatial mapping of sensory features has proven useful in elucidating circuit mechanisms that underlie sensory representations in the brain.
