Complementary Sensory and Associative Microcircuitry in Primary Olfactory Cortex [PDF]

, 2011
The three-layered primary olfactory (piriform) cortex is the largest component of the olfactory cortex. Sensory and intracortical inputs converge on principal cells in the anterior piriform cortex (aPC).Wecharacterize organization principles of the ...

Connectivity, plasticity, and function of neuronal circuits in the zebrafish olfactory forebrain [PDF]

, 2014
For most living animals such as worms, insects, fishes, rodents and humans, chemical cues from the environment (odorants) play critical roles in guiding behaviors important for survival, including preying, mating, breeding, and escaping.

Properties of doublecortin-(DCX)-expressing cells in the piriform cortex compared to the neurogenic dentate gyrus of adult mice.

PLoS ONE, 2011
The piriform cortex receives input from the olfactory bulb and (via the entorhinal cortex) sends efferents to the hippocampus, thereby connecting the two canonical neurogenic regions of the adult rodent brain.

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.

Odor fear conditioning modifies piriform cortex local field potentials both during conditioning and during post-conditioning sleep.

PLoS ONE, 2011
BackgroundSleep plays an active role in memory consolidation. Sleep structure (REM/Slow wave activity [SWS]) can be modified after learning, and in some cortical circuits, sleep is associated with replay of the learned experience.

Neuromodulation and the Functional Dynamics of Piriform Cortex [PDF]

Chemical Senses, 2001
Acetylcholine and norepinephrine have a number of effects at the cellular level in the piriform cortex. Acetylcholine causes a depolarization of the membrane potential of pyramidal cells and interneurons, and suppresses the action potential frequency accommodation of pyramidal cells.

Functional imaging of the piriform cortex in focal epilepsy [PDF]

Experimental Neurology, 2020
Experiments in animal models have identified specific brain regions such as the deep anterior piriform cortex as important for controlling the initiation or propagation of both generalized and focal seizure activity. However, there is little experimental evidence to translate these observations to the control of focal seizures in humans.

Odor identity coding by distributed ensembles of neurons in the mouse olfactory cortex

eLife, 2017
Olfactory perception and behaviors critically depend on the ability to identify an odor across a wide range of concentrations. Here, we use calcium imaging to determine how odor identity is encoded in olfactory cortex.

Assessment of olfactory information in the human brain using 7-Tesla functional magnetic resonance imaging

NeuroImage, 2021
Olfaction could prove to be an early marker of neurodegenerative diseases, including Alzheimer's and Parkinson's diseases. To use olfaction for disease diagnosis, elucidating the standard olfactory functions in healthy humans is necessary.

Expression time course and spatial distribution of activated caspase-3 after experimental status epilepticus: Contribution of delayed neuronal cell death to seizure-induced neuronal injury

Neurobiology of Disease, 2005
Pilocarpine-induced status epilepticus (PCSE) is a widely used model to study neurodegeneration in limbic structures after prolonged epileptic seizures.
