Emotional modulation of cortical activity during gum chewing: A functional near-infrared spectroscopy study

Frontiers in Neuroscience, 2022
Distinct brain regions are known to be associated with various emotional states. Cortical activity may be modulated by emotional states that are triggered by flavors during food intake.

Odorant Receptor Inhibition Is Fundamental to Odor Encoding [PDF]

Current Biology, 2019
SUMMARYMost natural odors are complex mixtures of many volatile components, competing to bind odorant receptors (ORs) expressed in olfactory sensory neurons (OSNs) of the nose. To date surprisingly little is known about how OR antagonism shapes neuronal representations in the periphery of the olfactory system.

Effective Monte Carlo simulation on System-V massively parallel associative string processing architecture [PDF]

, 1999
We show that the latest version of massively parallel processing associative string processing architecture (System-V) is applicable for fast Monte Carlo simulation if an effective on-processor random number generator is implemented. Our lagged Fibonacci

Contribution of the cyclic nucleotide gated channel subunit, CNG-3, to olfactory plasticity in Caenorhabditis elegans. [PDF]

, 2017
In Caenorhabditis elegans, the AWC neurons are thought to deploy a cGMP signaling cascade in the detection of and response to AWC sensed odors. Prolonged exposure to an AWC sensed odor in the absence of food leads to reversible decreases in the animal's ...

Power-Law Distributions of Dynamic Cascade Failures in Power-Grid Models

Entropy, 2020
Power-law distributed cascade failures are well known in power-grid systems. Understanding this phenomena has been done by various DC threshold models, self-tuned at their critical point.

Olfactory receptor neurons generate multiple response motifs, increasing coding space dimensionality

eLife, 2023
Odorants binding to olfactory receptor neurons (ORNs) trigger bursts of action potentials, providing the brain with its only experience of the olfactory environment.

Shedding Light on Inter-Individual Variability of Olfactory Circuits in Drosophila

Frontiers in Behavioral Neuroscience, 2022
Inter-individual differences in behavioral responses, anatomy or functional properties of neuronal populations of animals having the same genotype were for a long time disregarded.

Odors Associated With Autobiographical Memory Induce Visual Imagination of Emotional Scenes as Well as Orbitofrontal-Fusiform Activation

Frontiers in Neuroscience, 2021
Specific odors can induce memories of the past, especially those associated with autobiographical and episodic memory. Odors associated with autobiographical memories have been found to elicit stronger activation in the orbitofrontal cortex, hippocampus,

The Potential Use of Volatile Biomarkers for Malaria Diagnosis

Diagnostics, 2021
Pathogens may change the odor and odor-related biting behavior of the vector and host to enhance pathogen transmission. In recent years, volatile biomarker investigations have emerged to identify odors that are differentially and specifically released by

Odors: from chemical structures to gaseous plumes [PDF]

, 2020
We are immersed within an odorous sea of chemical currents that we parse into individual odors with complex structures. Odors have been posited as determined by the structural relation between the molecules that compose the chemical compounds and their ...
