Odor coding in piriform cortex: mechanistic insights into distributed coding.

Current Opinion in Neurobiology, 2020
Olfaction facilitates a large variety of animal behaviors such as feeding, mating, and communication. Recent work has begun to reveal the logic of odor transformations that occur throughout the olfactory system to form the odor percept.

Top-down feedback enables flexible coding strategies in the olfactory cortex

Cell Reports, 2022
Summary: In chemical sensation, multiple models have been proposed to explain how odors are represented in the olfactory cortex. One hypothesis is that the combinatorial identity of active neurons within sniff-related time windows is critical, whereas ...

Neural mechanisms of economic choices in mice [PDF]

, 2020
Economic choices entail computing and comparing subjective values. Evidence from primates indicates that this behavior relies on the orbitofrontal cortex. Conversely, previous work in rodents provided conflicting results. Here we present a mouse model of

Resection of piriform cortex predicts seizure freedom in temporal lobe epilepsy

Annals of Clinical and Translational Neurology, 2020
Transsylvian selective amygdalo‐hippocampectomy (tsSAHE) represents a generally recognized surgical procedure for drug‐resistant mesial temporal lobe epilepsy (mTLE). Although postoperative seizure freedom can be achieved in about 70% of tsSAHE, there is

Neurons and circuits for odor processing in the piriform cortex [PDF]

, 2013
Increased understanding of the early stages of olfaction has lead to a renewed interest in the higher brain regions responsible for forming unified ‘odor images’ from the chemical components detected by the nose.

Serotonergic afferents from the dorsal raphe decrease the excitability of pyramidal neurons in the anterior piriform cortex

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Serotonergic neurons in the dorsal raphe nucleus have been implicated in olfactory learning and processing of olfactory information. While the piriform cortex is an important olfactory center critically involved in olfactory learning and ...

Representations of Odor in the Piriform Cortex [PDF]

Neuron, 2009
Olfactory perception is initiated by the recognition of odorants by a large repertoire of receptors in the sensory epithelium. A dispersed pattern of neural activity in the nose is converted into a segregated map in the olfactory bulb. How is this representation transformed at the next processing center for olfactory information, the piriform cortex ...

Role of Projections between Piriform Cortex and Orbitofrontal Cortex in Relapse to Fentanyl Seeking after Palatable Food Choice-Induced Voluntary Abstinence

Journal of Neuroscience, 2020
We recently developed a rat model of relapse to drug seeking after food choice-induced voluntary abstinence. Here, we used this model to study the role of the orbitofrontal cortex (OFC) and its afferent projections in relapse to fentanyl seeking.

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 ...

Synaptic Organization of Anterior Olfactory Nucleus Inputs to Piriform Cortex

Journal of Neuroscience, 2020
Odors activate distributed ensembles of neurons within the piriform cortex, forming cortical representations of odor thought to be essential to olfactory learning and behaviors. This odor response is driven by direct input from the olfactory bulb, but is
