Selective Extinction through Cognitive Evaluation: Linking Emotion Regulation and Extinction
European Journal of Neuroscience, 2018 It has been proposed that the extinction of conditioned fear and the instructed regulation of emotion engage common ventromedial prefrontal (vmPFC) circuitry, indicating common underlying processes. Here we report an fMRI study using a novel task designed to investigate the neural overlap between cognitive emotion regulation and extinction of ...

Interstellar Extinction from Large Surveys
Open Astronomy, 2003 Under some assumptions, information on interstellar extinction may be obtained from modern large photometric survey data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from various surveys.

Chamber volume development, metabolic rates, and selective extinction in cephalopods. [PDF]
Sci Rep, 2020 Reconstructing the physiology of extinct organisms is key to understanding mechanisms of selective extinction during biotic crises. Soft tissues of extinct organisms are rarely preserved and, therefore, a proxy for physiological aspects is needed.

Molecular BrainAdenylyl cyclase 1 (AC1) is a selective subtype of ACs, which is selectively expressed in neurons. The activation of AC1 is activity-dependent, and AC1 plays an important role in cortical excitation that contributes to chronic pain and related emotional ...

On Triassic Murchisonia-like gastropods—surviving the end-Permian extinction to become extinct in the Late Triassic [PDF]
Acta Palaeontologica Polonica, 2023 High-spired Murchisonia-like slit-band gastropods are an important component of late Paleozoic gastropod faunas. Twenty-seven genera of such gastropods have been reported from the Permian, most of which representing the caenogastropod family ...

Sexual selection and the risk of extinction in birds [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 2003 The relationship between sexual selection and extinction risk has rarely been investigated. This is unfortunate because extinction plays a key role in determining the patterns of species richness seen in extant clades, which form the basis of comparative studies into the role that sexual selection may play in promoting speciation.

Frontiers in Behavioral Neuroscience, 2022 Facilitation of fear extinction is a desirable action for the drugs to treat fear-related diseases, such as posttraumatic stress disorder (PTSD). We previously reported that a selective agonist of the δ-opioid receptor (DOP), KNT-127, facilitates ...

Dynamics of extinction and the selection of nature reserves [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 2002 Familiar quantitative reserve-selection techniques are tailored to simple decision problems, where the representation of species is sought at minimum cost. However, conservationists have begun to ask whether representing species in reserve networks is sufficient to avoid local extinctions within selected areas.
