Article
Social encounters are associated with varying degrees of emotional arousal and stress. The mechanisms underlying adequate socioemotional balance are unknown. The medial amygdala (MeA) is a brain region associated with social behavior in mice. Corticotropin-releasing factor receptor type-2 (CRF-R2) and its specific ligand urocortin-3 (Ucn3), known c...

Social behavior in mammals is often studied in pairs under artificial conditions, yet groups may rely on more complicated social structures. Here, we use a novel system for tracking multiple animals in a rich environment to characterize the nature of group behavior and interactions, and show strongly correlated group behavior in mice. We have found...

Personality traits can offer considerable insight into the biological basis of individual differences. However, existing approaches toward understanding personality across species rely on subjective criteria and limited sets of behavioral readouts, which result in noisy and often inconsistent outcomes. Here we introduce a mathematical framework for...

We can now track the position of every fly's leg or immerse a tiny fish inside a virtual world by monitoring its gaze in real time. Yet capturing animals' posture or gaze is not like understanding their behavior. Instead, behaviors are still often interpreted by human observers in an anthropomorphic manner. Even newer tools that automatically class...

For animals, the ability to hide and retrieve valuable information, such as the location of food, can mean the difference between life and death. Here, we propose that to achieve this, their brain uses spatial cells similarly to how we utilize encryption for data security. Some animals are able to cache hundreds of thousands of food items annually...

Differences in animal personalities are generally hard to measure - even in an animal as common as the house mouse. Yet, in some rare cases, nature has provided us with clear visual cues as to the nature of a specific individual. These so-called badges are the case for the side botched lizard, often referred to as the 'rock-paper-scissor' lizard. H...

Complex behavioral phenotyping techniques are becoming more prevalent in the field of behavioral neuroscience, and thus methods for manipulating neuronal activity must be adapted to fit into such paradigms. Here, we present a head-mounted, magnetically activated device for wireless optogenetic manipulation that is compact, simple to construct, and...

Neural networks seem to be able to handle almost any task they face. This feat involves coping efficiently with different data types, at multiple scales, and with varying statistical properties. Here, we show that this so-called optimal coding can occur at the single-neuron level and does not require adaptation. Differentiator neurons, i.e., neuron...

Article
POMC neurons in the arcuate nucleus of the hypothalamus are central components of systems regulating appetite and energy homeostasis. Here, we report on the establishment of a mouse model in which the RNase III ribonuclease Dicer-1 has been specifically deleted from POMC expressing neurons (POMC(ΔDCR)), leading to postnatal cell death. Mice are bor...
