Studying dominance and aggression requires ethologically relevant paradigms
Curr Opin Neurobiol. 2024 Apr 30;86:102879. doi: 10.1016/j.conb.2024.102879. Online ahead of print.ABSTRACTAlthough aggression is associated with several psychiatric disorders, there is no effective treatment nor a rigorous definition for "pathological aggression". Mice make a valuable model for studying aggression. They have a dynamic social structure that depends on the habitat and includes reciprocal interactions between the mice's aggression levels, social dominance hierarchy (SDH), and resource allocation. Nevertheless, the classical behavioral tests for territorial aggression and SDH in mice are reductive and have li...

A conserved brainstem region for instinctive behaviour control: The vertebrate periaqueductal gray
Curr Opin Neurobiol. 2024 Apr 24;86:102878. doi: 10.1016/j.conb.2024.102878. Online ahead of print.ABSTRACTInstinctive behaviours have evolved across animal phyla and ensure the survival of both the individual and species. They include behaviours that achieve defence, feeding, aggression, sexual reproduction, or parental care. Within the vertebrate subphylum, the brain circuits that support instinctive behaviour output are evolutionarily conserved, being present in the oldest group of living vertebrates, the lamprey. Here, I will provide an evolutionary and comparative perspective on the function of a conserved brainstem r...

Cognitive maps and the magnetic sense in vertebrates
Curr Opin Neurobiol. 2024 Apr 23;86:102880. doi: 10.1016/j.conb.2024.102880. Online ahead of print.ABSTRACTNavigation requires a network of neurons processing inputs from internally generated cues and external landmarks. Most studies on the neuronal basis of navigation in vertebrates have focused on rats and mice and the canonical senses vision, hearing, olfaction, and somatosensation. Some animals have evolved the ability to sense the Earth's magnetic field and use it for orientation. It can be expected that in these animals magnetic cues are integrated with other sensory cues in the cognitive map. We provide an overview ...

Dynamic skin behaviors in cephalopods
Curr Opin Neurobiol. 2024 Apr 22;86:102876. doi: 10.1016/j.conb.2024.102876. Online ahead of print.ABSTRACTThe coleoid cephalopods (cuttlefish, octopus, and squid) are a group of soft-bodied mollusks that exhibit a wealth of complex behaviors, including dynamic camouflage, object mimicry, skin-based visual communication, and dynamic body patterns during sleep. Many of these behaviors are visually driven and engage the animals' color changing skin, a pixelated display that is directly controlled by neurons projecting from the brain. Thus, cephalopod skin provides a direct readout of neural activity in the brain. During camo...

Microglia phagocytic mechanisms: Development informing disease
Curr Opin Neurobiol. 2024 Apr 16;86:102877. doi: 10.1016/j.conb.2024.102877. Online ahead of print.ABSTRACTMicroglia are tissue-resident macrophages and professional phagocytes of the central nervous system (CNS). In development, microglia-mediated phagocytosis is important for sculpting the cellular architecture. This includes the engulfment of dead/dying cells, pruning extranumerary synapses and axons, and phagocytosing fragments of myelin sheaths. Intriguingly, these developmental phagocytic mechanisms by which microglia sculpt the CNS are now appreciated as important for eliminating synapses, myelin, and proteins durin...
