Anticipation-induced delta phase reset improves human olfactory perception.
PLoS Biology, 2020 Anticipating an odor improves detection and perception, yet the underlying neural mechanisms of olfactory anticipation are not well understood. In this study, we used human intracranial electroencephalography (iEEG) to show that anticipation resets the ...

Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Alzheimer's disease (AD) is one of the most common neurological disorders affecting older adults, with approximately 7.2 million cases only in the United States. This number is projected to increase to 13.8 million in the United States by 2060, leading to increased expenditures for healthcare, long‐term care and hospice services. Consequently,

A transformation from temporal to ensemble coding in a model of piriform cortex
eLife, 2018 Different coding strategies are used to represent odor information at various stages of the mammalian olfactory system. A temporal latency code represents odor identity in olfactory bulb (OB), but this temporal information is discarded in piriform cortex

Synaptic events that generate fast oscillations in piriform cortex [PDF]
The Journal of Neuroscience, 1993 Prominent, odor-evoked, fast (40–60 Hz) oscillations have been reported in the olfactory bulb and piriform (primary olfactory) cortex of both awake-behaving and anesthetized animals. The present study used current source-density analysis to examine the origin of the fast oscillations evoked by single weak shocks to afferent fibers.

Movement Disorders, EarlyView.Abstract Background Transsynaptic α‐synuclein propagation plays a crucial role in the progression of Lewy body disease. We previously demonstrated that an α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazolepropionic acid receptor antagonist, perampanel, blocks neuronal uptake of α‐synuclein preformed fibrils (PFFs) in an activity‐dependent manner.

NMDA spikes mediate amplification of inputs in the rat piriform cortex
eLife, 2018 The piriform cortex (PCx) receives direct input from the olfactory bulb (OB) and is the brain's main station for odor recognition and memory. The transformation of the odor code from OB to PCx is profound: mitral and tufted cells in olfactory glomeruli ...

Molecular signatures of neural connectivity in the olfactory cortex
Nature Communications, 2016 The piriform cortex projects to multiple brain regions involved in diverse aspects of olfactory behavior but information about the organization of these outputs is lacking.

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 ...
