In this episode we hear about tinnitus and hyperacusis, salamanders, chemical harpoons, and the role of ultrasound and song in the mating rituals of mice and flies.
Real-time monitoring of oxytocin-loaded vesicles and synaptic actin dynamics in zebrafish reveal that Slit3-Robo2-Cdc42 signalling maintains steady-state levels of mature oxytocin neuropeptide readily primed to be secreted upon physiological demand.
The higher amount of cortical immature neurons in brains with expanded neocortices may represent a reservoir of young cells for mammals with reduced neurogenesis.
In medaka fish, galanin-expressing neurons in the medial preoptic area occur nearly exclusively in males and mediate androgen-dependent male–male aggressive chases.
Adiponectin signaling integrates metabolic state information to regulate circadian clock function in hypothalamic appetite regulating centers, food intake rhythms, and body weight.
Bonobo groups that share overlapping ranging areas and engage in regular social exchange show "behavioural group identity" of hunting techniques in the absence of local ecological variation.
β3-AR signalling via cGMP in cardiomyocytes is regulated via phosphodiesterase 2 and 5 degradation, it is potentially cardioprotective, but dysregulated in heart failure through signal redistribution and higher phosphodiesterase activity.
