The neural circuit architecture of social hierarchy in rodents and primates

Abstract/Results: Social status is recognized as a major determinant of social behavior and health among animals; however, the neural circuits supporting the formation and navigation of social hierarchies remain under extensive research. Available evidence suggests the prefrontal cortex is a keystone in this circuit, but upstream and downstream candidates are progressively emerging. In this review, we compare and integrate findings from rodent and primate studies to create a model of the neural and cellular networks supporting social hierarchies, both from a macro (i.e., circuits) to a micro-scale perspective (microcircuits and synapses). We start by summarizing the literature on the prefrontal cortex and other relevant brain regions to expand the current “prefrontal-centric” view of social hierarchy behaviors. Based on connectivity data we also discuss candidate regions that might inspire further investigation, as well as the caveats and strategies that have been used to further our understanding of the biological substrates underpinning social hierarchy and dominance.

In vivo recordings in freely behaving mice using independent silicon probes targeting multiple brain regions
Publication year: 2023

Abstract/Results: ABSTRACT:
In vivo recordings in freely behaving animals are crucial to understand the neuronal circuit basis of behavior. Although current multi-channel silicon probes provide unparalleled sampling density, the study of interacting neuronal populations requires the implantation of multiple probes across different regions of the brain. Ideally, these probes should be independently adjustable, to maximize the yield, and recoverable, to mitigate costs. In this work, we describe the implementation of a miniaturized 3D-printed headgear system for chronic in vivo recordings in mice using independently movable silicon probes targeting multiple brain regions. We successfully demonstrated the performance of the headgear by simultaneously recording the neuronal activity in the prelimbic cortex and dorsal hippocampus. The system proved to be sturdy, ensuring high-quality stable recordings and permitted reuse of the silicon probes, with no observable interference in mouse innate behaviors.

Abstract/Results:
ABSTRACT:
Background
Dominance relationships among social animals have been proposed to increase survival, by reducing violence and by promoting an efficient sharing of resources. Social rank is dictated by a combination of intrinsic and extrinsic factors, including the outcomes of previous confrontations against specific individuals. This observation suggests that dominance behavior could be directly influenced by social memory. However, the circuit basis of social memory remains poorly understood. Previous studies suggested that ventral hippocampus, most specifically CA2 and ventral CA1, are necessary for social memory, but the mechanisms whereby social memory is used to guide social behavior remained elusive. Despite the diversity of ventral CA1 targets, prefrontal circuits are a strong candidate to integrate social memory with task-relevant information during dyadic encounters. In this sense, we hypothesized that CA2 social mnemonic information is routed through ventral CA1 and drives prefrontal ensembles, producing socialrelated prefrontal patterns necessary to support social memory during dyadic social interactions.
Aims
We aimed to characterize the dynamics of prefrontal-hippocampal circuits during dyadic social encounters. For that, one part of our project aimed at discovering correlative evidence of social-related prefrontal patterns during social interactions. The second part of the project focused on dissecting the mechanisms whereby such social correlates are generated in prefrontal circuits.
Methods
To address circuit dynamics during social encounters, we performed in vivo electrophysiological recordings in C57BL6 mice, while they interacted with conspecifics with different social ranks and with different degrees of familiarity. To further dissect the mechanisms whereby social correlates are generated in prefrontal circuits, we recorded a genetically engineered mouse model known to display hippocampal dysfunction and deficits of social memory – the conditional GPRASP2 mouse. For both approaches, we combined standard behavior analysis with classical metrics of in vivo electrophysiological activity.
Results
This work sheds light on the circuit mechanisms supporting social memory and social behaviors in prefrontalhippocampal circuits. Specifically, we found both social-sensitive and rank-sensitive cells in prefrontal circuits, suggesting that prefrontal/cingulate cortex is engaged by the social and dominance variables of the task. We also found that, during social contacts, prefrontal circuits are entrained by high theta rhythms, which were absent in an animal model suffering from hippocampal and social memory dysfunction, suggesting that these high theta oscillations might be the communication channel whereby social-related hippocampal patterns shape PFC/CG circuits.
Conclusions
Our work identified two novel activity biomarkers of social and dominance behavior in prefrontal circuits in the mouse.
