Facilitating Adaptive Emotion Processing and Somatic Reappraisal Sustained Mindful Interoceptive Attention.

Front Psychol 2021 8;12:578827. Epub 2021 Sep 8.

Osher Center for Integrative Medicine, Neuroscape Center, Department of Psychiatry and Behavioral Sciences, University of California, San Francisco, CA, United States.

Emotions are by nature embodied, as the brain has evolved to quickly assess the emotional significance of stimuli and output signals to the body's viscera and periphery to aid adaptive responses. Emotions involve both implicit bodily and explicit narrative processes, and patients may experience transdiagnostic distress when bodily signals are not attended to and holistically integrated with explicit narratives about experience. Similarly, therapists may be trained in more implicit body-based approaches (i. Read More

Cantil - a new organ or a morphological oddity?

New Phytol 2021 Sep 19. Epub 2021 Sep 19.

School of Biology, Indian Institute of Science Education and Research, Thiruvananthapuram (IISER TVM), Maruthamala PO, Vithura Thiruvananthapuram, Kerala, 695551, India.

Cantil is reported as a newfound organ specific to the model plant Arabidopsis thaliana that is prominent only in short-day grown wild-type accessions or long-day grown genetic mutants with delayed vegetative to reproductive transition. Here, we show that cantils (previously known as nubbins) arise as one of the many phenotypic consequences of aneuploidy resulting from chromosome dosage imbalances in Arabidopsis polyaneuploids despite normal reproductive transition in long-day photoperiods. Without a demonstrated function or adaptive significance, we view cantils as a morphological oddity rather than a separate organ, and as a manifestation of physiological perturbations triggered by genetic and environmental factors.

The evolutionary and physiological significance of the Hif pathway in teleost fishes.

J Exp Biol 2021 Sep 17;224(18). Epub 2021 Sep 17.

Department of Biology, University of Ottawa, 30 Marie Curie, Ottawa, ON, Canada, K1N 6N5.

The hypoxia-inducible factor (HIF) pathway is a key regulator of cellular O2 homeostasis and an important orchestrator of the physiological responses to hypoxia (low O2) in vertebrates. Fish can be exposed to significant and frequent changes in environmental O2, and increases in Hif-α (the hypoxia-sensitive subunit of the transcription factor Hif) have been documented in a number of species as a result of a decrease in O2. Here, we discuss the impact of the Hif pathway on the hypoxic response and the contribution to hypoxia tolerance, particularly in fishes of the cyprinid lineage, which includes the zebrafish (Danio rerio).

Evolutionary ecology of climacteric and non-climacteric fruits.

Biol Lett 2021 09 15;17(9):20210352. Epub 2021 Sep 15.

Department of Biological Sciences, Tokyo Metropolitan University, Tokyo, Japan.

Fleshy fruits can be divided between climacteric (CL, showing a typical rise in respiration and ethylene production with ripening after harvest) and non-climacteric (NC, showing no rise). However, despite the importance of the CL/NC traits in horticulture and the fruit industry, the evolutionary significance of the distinction remains untested. In this study, we tested the hypothesis that NC fruits, which ripen only on the plant, are adapted to tree dispersers (feeding in the tree), and CL fruits, which ripen after falling from the plant, are adapted to ground dispersers.

Somatostatin Interneurons of the Insula Mediate QR2 Dependent Novel Taste Memory Enhancement.

eNeuro 2021 Sep 13. Epub 2021 Sep 13.

Sagol Department of Neuroscience, University of Haifa, 199 Aba Khoushy Ave., Mount Carmel, Haifa, 3498838, Israel

Forming long term memories is crucial for adaptive behavior and survival in changing environments. The molecular consolidation processes which underlie the formation of these long term memories are dependent on protein synthesis in excitatory and SST expressing neurons. A centrally important, parallel process to this involves the removal of the memory constraint quinone reductase 2 (QR2), which has been recently shown to enhance memory consolidation for novel experiences in the cortex and hippocampus, via redox modulation.

Multimodal analysis of electroencephalographic and electrooculographic signals.

Comput Biol Med 2021 Aug 27;137:104809. Epub 2021 Aug 27.

Department of Computer Science, Faculty of Computers and Information, Mansoura University, 35511, Egypt. Electronic address:

Electrooculography (EOG) is a method to concurrently obtain electrophysiological signals accompanying an Electroencephalography (EEG), where both methods have a common cerebral pattern and imply a similar medical significance. The most common electrophysiological signal source is EOG that contaminated the EEG signal and thereby decreases the accuracy of measurement and the predicated signal strength. In this study, we introduce a method to improve the correction efficiency for EOG artifacts (EOAs) on raw EEG recordings: We retrieve cerebral information from three EEG signals with high system performance and accuracy by applying feature engineering and a novel machine-learning (ML) procedure.
