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.

On the ictogenic properties of the piriform cortex in vitro [PDF]
Epilepsia, 2012 SummaryPurpose: The piriform cortex (PC) is known to be epileptic‐prone and it may be involved in the manifestation of limbic seizures. Herein, we have characterized some electrophysiologic and pharmacologic properties of the spontaneous epileptiform activity generated by PC networks maintained in vitro.Methods: We performed field potential recordings ...

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.

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.

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.

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.

Individual odor hedonic perception is coded in temporal joint network activity
NeuroImage, 2021 Intro: The human sense of smell is highly individual and characterized by a strong variability in the perception and evaluation of olfactory stimuli, depending on cultural imprint and current physiological conditions.

eLife, 2020 Pattern completion, or the ability to retrieve stable neural activity patterns from noisy or partial cues, is a fundamental feature of memory. Theoretical studies indicate that recurrently connected auto-associative or discrete attractor networks can ...
