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.

Motor Cortex Response to Pleasant Odor Perception and Imagery: The Differential Role of Personality Dimensions and Imagery Ability

Frontiers in Human Neuroscience, 2022
BackgroundNeuroimaging studies have shown a complex pattern of brain activation during perception of a pleasant odor and during its olfactory imagery. To date, little is known regarding changes in motor cortex excitability during these tasks.

A Novel Focal Seizure Pattern Generated in Superficial Layers of the Olfactory Cortex

Journal of Neuroscience, 2017
Seizure patterns identified in focal epilepsies caused by diverse etiologies are likely due to different pathogenic mechanisms. We describe here a novel, region-specific focal seizure pattern that mimics seizure activity observed in a subpopulation of ...

Moyamoya Disease and the Risk of Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Moyamoya disease (MMD) is a rare cerebrovascular disorder characterized by the progressive narrowing of arteries at the base of the brain, forming abnormal collateral vascular networks. While vascular parkinsonism is noted in MMD, its link to Parkinson's disease (PD) has not been explored.

Purkinje Cell Loss in Essential Tremor: Collective Data From 215 Brains Over a 21‐Year Period

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Essential tremor is a highly prevalent movement disorder. Pathological changes observed in essential tremor cerebella center around Purkinje cells and neighboring neuronal populations. Postmortem studies have variably, but not always, shown reduced Purkinje cell counts in essential tremor compared to controls.

Brain Activations in Response to Prolonged Citral Inhalation Detected by Manganese-Enhanced Magnetic Resonance Imaging (MEMRI)

Chinese Journal of Magnetic Resonance, 2020
In this study, an olfactory inhalation instrument was devised to allow the rats to inhale volatile citral or odorless air. Manganese-enhanced magnetic resonance imaging (MEMRI) was used to reveal changes of accumulative brain activities after a 24 h ...

Olfactory cortical neurons read out a relative time code in the olfactory bulb [PDF]

, 2014
Odor stimulation evokes complex spatiotemporal activity in the olfactory bulb, suggesting that the identity of activated neurons as well as the timing of their activity convey information about odors.

Post‐COVID Fatigue Is Associated With Reduced Cortical Thickness After Hospitalization

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuropsychiatric symptoms are among the most prevalent sequelae of COVID‐19, particularly among hospitalized patients. Recent research has identified volumetric brain changes associated with COVID‐19. However, it currently remains poorly understood how brain changes relate to post‐COVID fatigue and cognitive deficits.

Sensory memory for odors is encoded in spontaneous correlated activity between olfactory glomeruli [PDF]

, 2006
Sensory memory is a short-lived persistence of a sensory stimulus in the nervous system, such as iconic memory in the visual system. However, little is known about the mechanisms underlying olfactory sensory memory.
