Interrogating Basolateral Amygdala Activity during Social Behaviour at Single-Cell and Population Levels

Projektbeschreibung

Darstellung der Gehirnaktivität während sozialer Interaktion

Soziale Lebewesen wie der Mensch und andere Primaten nehmen verschiedene Signale aus der Umwelt und dem sozialen Umfeld wahr und interpretieren diese, um notwendige Entscheidungen zu treffen. Allerdings ist wenig darüber bekannt, welche Mechanismen diesen Prozessen zugrunde liegen und wie das Gehirn diese internen Informationen aktiviert. Das EU-finanzierte Projekt AMYGDALA-ELECTROPHYS wird neuronale Ableitungen bei Ratten durchführen, um die Aktivität im basolateralen Amygdala-Komplex (BLA) während sozialer Interaktionen zu untersuchen. Durch die Entschlüsselung dieser Vorgänge werden die Forschenden die Faktoren (wie beispielsweise Geschlecht und Alter) ermitteln und verstehen, welche die neuronalen Abläufe im BLA und damit das Sozialverhalten steuern.

Ziel

The accurate perception and interpretation of social stimuli is crucial for survival in social species including rodents, primates and humans. Before deciding whether to mate, fight or avoid, an animal must process multisensory cues to activate an internal representation of the social environment that answers key questions (Sex? Age? Friend? Foe? Previously encountered?). Little is known about how the brain develops and activates this representation. We will focus on the role of neuronal firing in the basolateral amygdala complex (BLA) in processing and integrating social cues.

In the first stage of this research, we will use neuropixel silicon probes to conduct large-scale recordings of the BLA in rats during social interaction with conspecifics (juvenile rats, male rats and female rats). We can record from large populations of neurons across weeks in freely-moving rats during social interaction. Second, by analysing the activity of single neurons in the BLA, we can characterize the specificity and responsivity of single neurons to social interaction and understand the mitigating factors (gender of conspecific, sexual receptivity, age, previous history). Third, we can decode the population activity of the BLA during social activity to understand how BLA connectivity changes during social interaction and with experience. Finally, we will use optical tagging of anatomically-defined ensembles of BLA neurons to understand how BLA projections code for specific properties of social activity. Success in this project will provide an understanding of how neural computation occurs within the BLA.
