Identification of olfactory alarm substances in zebrafish Curr. Biol. (IF 9.2) Pub Date : 2024-02-28 Miwa Masuda, Sayoko Ihara, Naoki Mori, Tetsuya Koide, Nobuhiko Miyasaka, Noriko Wakisaka, Keiichi Yoshikawa, Hidenori Watanabe, Kazushige Touhara, Yoshihiro Yoshihara
Escaping from danger is one of the most fundamental survival behaviors for animals. Most freshwater fishes display olfactory alarm reactions in which an injured fish releases putative alarm substances from the skin to notify its shoaling company about the presence of danger. Here, we identified two small compounds in zebrafish skin extract, designated as ostariopterin and daniol sulfate. Ostariopterin

Lateral hypothalamic GABAergic neurons encode alcohol memories Curr. Biol. (IF 9.2) Pub Date : 2024-02-28 Isis Alonso-Lozares, Pelle Wilbers, Lina Asperl, Sem Teijsse, Charlotte van der Neut, Dustin Schetters, Yvar van Mourik, Allison J. McDonald, Tim Heistek, Huibert D. Mansvelder, Taco J. De Vries, Nathan J. Marchant
In alcohol use disorder, the alcohol memories persist during abstinence, and exposure to stimuli associated with alcohol use can lead to relapse. This highlights the importance of investigating the neural substrates underlying not only relapse but also encoding and expression of alcohol memories. GABAergic neurons in the lateral hypothalamus (LH-GABA) have been shown to be critical for food-cue memories

Advanced feedback enhances sensorimotor adaptation Curr. Biol. (IF 9.2) Pub Date : 2024-02-22 Tianhe Wang, Guy Avraham, Jonathan S. Tsay, Tanvi Thummala, Richard B. Ivry
It is widely recognized that sensorimotor adaptation is facilitated when feedback is provided throughout the movement compared with when it is provided at the end of the movement. However, the source of this advantage is unclear: continuous feedback is more ecological, dynamic, and available earlier than endpoint feedback. Here, we assess the relative merits of these factors using a method that allows

Dacks
Natural behaviors are a coordinated symphony of motor acts that drive reafferent (self-induced) sensory activation. Individual sensors cannot disambiguate exafferent (externally induced) from reafferent sources. Nevertheless, animals readily differentiate between these sources of sensory signals to carry out adaptive behaviors through corollary discharge circuits (CDCs), which provide predictive motor

Dopaminergic neurons (DANs) in the substantia nigra (SNc) have been related to movement speed, and loss of these neurons leads to bradykinesia in Parkinson’s disease (PD). However, other aspects of movement vigor are also affected in PD; for example, movement sequences are typically shorter. However, the relationship between the activity of DANs and the length of movement sequences is unknown. We imaged

Growth and tension in explosive fruit Curr. Biol. (IF 9.2) Pub Date : 2024-02-14 Gabriella Mosca, Ryan C. Eng, Milad Adibi, Saiko Yoshida, Brendan Lane, Leona Bergheim, Gaby Weber, Richard S. Smith, Angela Hay
Exploding seed pods of the common weed have the remarkable ability to launch seeds far from the plant. The energy for this explosion comes from tension that builds up in the fruit valves. Above a critical threshold, the fruit fractures along its dehiscence zone and the two valves coil explosively, ejecting the seeds. A common mechanism to generate tension is drying, causing tissues to shrink. However

The outer corona plays an essential role at the onset of mitosis by expanding to maximize microtubule attachment to kinetochores. The low-density structure of the corona forms through the expansion of unattached kinetochores. It comprises the RZZ complex, the dynein adaptor Spindly, the plus-end directed microtubule motor centromere protein E (CENP-E), and the Mad1/Mad2 spindle-assembly checkpoint

Johnson, Toshihisa Kotake
Subzero temperatures are often lethal to plants. Many temperate herbaceous plants have a cold acclimation mechanism that allows them to sense a drop in temperature and prepare for freezing stress through accumulation of soluble sugars and cryoprotective proteins. As ice formation primarily occurs in the apoplast (the cell wall space), cell wall functional properties are important for plant freezing
