Convulsant actions of 4-aminopyridine on the guinea-pig olfactory cortex slice [PDF]

, 1982
The effects of bath-applied 4-aminopyridine on neurones and extracellular potassium and calcium concentrations were recorded in slices of guinea-pig olfactory cortex. Neurones were orthodromically activated by stimulating the lateral olfactory tract.

Orchestration of Hippocampal Information Encoding by the Piriform Cortex [PDF]

Cerebral Cortex, 2019
Abstract The hippocampus utilizes olfactospatial information to encode sensory experience by means of synaptic plasticity. Odor exposure is also a potent impetus for hippocampus-dependent memory retrieval. Here, we explored to what extent the piriform cortex directly impacts upon hippocampal information processing and storage.

Receptive Fields in the Rat Piriform Cortex [PDF]

Chemical Senses, 2001
Current models of odor discrimination in mammals involve molecular feature detection by a large family of diverse olfactory receptors, refinement of molecular feature extraction through precise projections of olfactory receptor neurons to the olfactory bulb to form an odor-specific spatial map of molecular features across glomerular layer, and ...

Odor-intensity Coding in the Anterior Piriform Cortex [PDF]

Chemical Senses, 2005
The primary olfactory cortex is defined as the region that receivesdirect fiber projection from the olfactory bulb (OB). The piriformcortex (PC) is the largest structure in the olfactory cortex. However,no ‘point to point’ anatomical connection between the OB and PChas been found (Haberly, 1998).

Optogenetic stimulation of lateral amygdala input to posterior piriform cortex modulates single-unit and ensemble odor processing

Frontiers in Neural Circuits, 2015
Olfactory information is synthesized within the olfactory cortex to provide not only an odor percept, but also a contextual significance that supports appropriate behavioral response to specific odor cues.

Multiscale Coupling From Mastication to Retronasal Aroma Perception: The PG‐DTCFN Model and Multiphysics Simulation

Advanced Science, EarlyView.
Using grilled lamb skewers as a model system, this work builds a multiscale coupling framework from oral processing to retronasal aroma perception, reveals dual‐kinetic release patterns and Electroencephalogram‐characterized central encoding features, and proposes an interpretable physics‐guided deep learning model validated by multiphysics simulation,

Altered functional connectivity within the default mode network in two animal models with opposing episodic memories. [PDF]

PLoS ONE, 2018
Memory enhancement and memory decline are two opposing cognitive performances commonly observed in clinical practice, yet the neural mechanisms underlying these two different phenomena remain poorly understood. Accumulating evidence has demonstrated that

Dual‐Organelle Secretome Conjugation and Organ‐Uptake Tracking (DuO‐SCOUT) Enables Deep and Sensitive Mapping of the Secreted Proteins

Advanced Science, EarlyView.
A novel dual‐organelle proximity labeling platform, DuO‐SCOUT, decodes the complex landscape of systemic organ‐organ communication by capturing both classical and unconventional secretomes. Application in metabolic models maps the adipose‐to‐brain secretory relay, identifying selective extra‐hypothalamic sites for adipose‐derived factors and expanding ...

Recurrent Circuitry Dynamically Shapes the Activation of Piriform Cortex [PDF]

, 2011
SummaryIn the piriform cortex, individual odorants activate a unique ensemble of neurons that are distributed without discernable spatial order. Piriform neurons receive convergent excitatory inputs from random collections of olfactory bulb glomeruli ...

Comparative analysis of cytoarchitectonic and neurochemical aspects of the globus pallidus in the rock cavy (Kerodon rupestris) and the common marmoset (Callithrix jacchus)

The Anatomical Record, EarlyView.
Abstract The globus pallidus (GP), a subcortical structure within the basal ganglia, plays a crucial role in modulating cortico‐subcortical circuits related to motor control and associative/limbic functions. However, the cytoarchitectonic and neurochemical organization of this structure remains poorly characterized in naturally existing wild‐type ...
