- Neuronal circuits and the magnetic sense: central questions
Summary: This paper reviews the circuits that process magnetic information in birds and mice, assesses the utility of emerging technologies and asks questions that are critical for the advancement of the field.
- Mitochondrial plasticity in the cerebellum of two anoxia-tolerant sharks: contrasting responses to anoxia/re-oxygenation
Highlighted Article: The brain mitochondria of reef sharks reveal some adaptations that parallel their contrasted physiological strategies to cope with environmental oxygen deprivation.
- Social stress increases plasma cortisol and reduces forebrain cell proliferation in subordinate male zebrafish (Danio rerio)
Summary: Elevated cortisol reduces cell proliferation in the telencephalon of socially subordinate male, but not female, zebrafish.
- HIF1α and physiological responses to hypoxia are correlated in mice but not in rats
Summary: Compared with SD rats, FVB mice have higher ventilatory and metabolic responses to hypoxia, higher induction of HIF-1α, and lower Glut1 protein expression in the brainstem.
- Transcriptomic analysis of instinctive and learned reward-related behaviors in honey bees
Highlighted Article: Brain gene expression analysis sheds new light on the relationship between instincts and learned behaviors and provides new insights into how the brain's reward system influences social behavior.
- On doing two things at once: dolphin brain and nose coordinate sonar clicks, buzzes and emotional squeals with social sounds during fish capture
Summary: Dolphins use sonar to hunt fish; they make different sounds and different decisions simultaneously.
- Stress in Atlantic salmon: response to unpredictable chronic stress
Summary: The unpredictable chronic stressor (UCS) paradigm, which mimics the effects of multiple stressors, causes dynamic changes at every level of the hypothalamic–pituitary gland–interrenal gland (HPI) axis of Atlantic salmon parr.
