A unique experimental model will be used to study the neurobiological basis of aggressive animal behavior and translate novel findings about its cellular and circuit underpinnings into human phenotypes of pathological aggression.
Specifically, the post-weaning social isolation model of early-life adverse experience allows experimental access to dissect the switch from functional adaptive aggression to excessive pathological aggressive behavior.
In male mice, conspecific chemostimuli trigger innate aggressive behavior.
The relevant aggression-promoting circuits along the(sensory) input to (aggressive) output axis comprise the accessory olfactory bulb (AOB), a hub for processing of social chemosignals, and the medial amygdala (MeA), a crucial control centre for regulation of aggressive behavior.
Therefore, this project addresses the principles that govern aggression-promoting information transfer along the AOB-to-MeA signaling pathway.

The focus will be on the influences of a provocative context on social threat processing in AMD under different testosterone
levels. Specifically, the project aims to analyze the modulating function of context under testosterone application versus
suppression on threat sensitivity in healthy controls as well as patient groups. Additionally, we will determine the
influence of endogenous hormone variations (testosterone, oxytocin, estrogen and cortisol) on NVS in high versus low
aggressive patients in a large group of patients recruited in Q01. With this sample, we will try to identify multidimensional
biosignatures based on hormonal levels in combination with fMRI measures of amygdala and amygdala-prefrontal
connectivity, NVS measures by questionnaires, aggression measures and psychopathological data.

We make use of threat-related chemosensory stimuli, namely body odor, acquired during aggressive behavior (boxing)
and unconsciously perceived, to investigate heightened amygdala responses to threat stimuli in aggressive patients. Body
odors have the major advantage of being directly projected into the amygdala, circumventing cortical preprocessing,
thereby enabling the differentiation of mechanisms between bottom-up altered limbic processing and top-down modulated
altered cognitive evaluation. We investigate the potential of such body odors to bias responses to ambiguous visual social
cues towards threat and their effects during peripersonal space (PPS) violation where they may be especially relevant.

The project employs fMRI and functional near-infrared
spectroscopy (fNIRS) hyperscanning techniques to explore how brain-to-brain synchrony and dynamic processes within
peer dyads facilitate or inhibit aggressive behavior under diverse levels of provocation in adolescent patients and controls.
In two fully interactive tasks, we will probe aggressive behavior towards a task partner, and quantify the building of
interpersonal trust/distrust applying a social interaction and economic exchange paradigm. These paradigms will be
employed within dyads in fMRI hyperscanning settings and extended by group-based fNIRS methods in triads to study
effects of peers, social exclusion, and coalitions on aggressive behavior in semi-naturalistic interactions. Between-brain
neural synchrony will be computed and related to everyday social experiences and individual predispositions to identify
markers for the prediction of aggressive behavior.

involved in the transfer of the patients phenotype to the mice, such as immune parameters, sex hormones, neuronal

Beta-hydroxy-butyrate (BHB), a ketone body, is negatively associated with aggressive behavior. BHB is a metabolite and an
active signaling substrate involved in epigenetic regulation of e.g., neurotrophic factor genes in the brain. Of the three
main ketone bodies, acetone, acetoacetate and BHB, acetone is a very volatile compound, mainly eliminated through
respiration, thus can be measured non-invasively in breath. A reduction of acetone in breath has been found to highly
correlate with BHB in blood and be associated with symptom severity in schizophrenia (Jiang et al. 2022). Using MR
spectroscopy, A08 aims to (1) identify whether acetone and other volatile organic compounds in breath are associated
with aggression and acute threat processing in mental disorders and (2) to examine whether these breath markers are
associated with direct metabolic brain correlates (like BHB, glutamate) and with the brain-derived neurotrophic factor
(BDNF) levels in plasma. In a translational approach, (3) we will test if supplementation of BHB reduces aggressive
behavior in mice.

TDCS will be used as an interventional tool to decrease aggression. Using a simultaneous
tDCS fMRI approach, the project aims to enhance cognitive control by repeated prefrontal brain stimulation, investigating
its effect on aggression. In addition to gauging tDCS responsivity, identifying the role of individual factors such as genetic
profiles in aggression will be a particular focus of this project. By examining brain activity at multiple time points (e.g.,
before, during multiple stimulation sessions and after tDCS), it will add to the understanding of mechanisms underlying
neural tDCS effects and help to identify individual factors that predict responsiveness to the stimulation. To determine
the therapeutic potential, we will include psychiatric patients with substance use problems, a group of criminal, violent
offenders, and healthy matched controls.

cognitive and emotion control deficits in the context of negative valence and threat interference and their association
with ACE in young offenders. Complementary to other projects, this project will focus on a group of young people
defined by their propensity to aggression showing at the same time more severe psychopathologies. In a series of studies
using multimodal imaging (EEG-fMRI, EEG-sMRI) in combination with naturalistic longitudinal follow-up (ecological
momentary assessment (EMA)) B02 will identify the neural mechanisms and predictors of self-regulation deficits as a
putative common developmental pathway for both, aggressive behavior, and psychopathology. Additionally, B02 will
seek to causally confirm neural network mechanisms of inhibitory control and emotion regulation deficits as the basis of
aggressive behavior and associated psychopathology by real-time EEG-triggered TMS-stimulation in young offenders.

Develop virtual scenarios to assess decision strategies in cartoon-like and naturalistic
contexts. The core question is how healthy individuals and patients make (mal-)adaptive aggressive decisions in social
conflicts given their threat sensitivity, cognitive functions, and learning experience. We plan to present mathematically
well-defined aggressive decision scenarios to healthy participants as well as patients across diagnostic categories with
high scores of aggressive behavior, threat sensitivity, and inference of hostile intent in others. Computational models that
accurately explain behavioral choices and neural responses (tested using fMRI and pupillometry) will be developed to
identify the aggressive decision strategies humans employ in approach-avoidance conflicts of increasing complexity and
ecological realism. The purpose will be to determine if patients use overly aggressive strategies that are not warranted by
the necessary defense of self-threats and underlying neural circuits.

make (mal-)adaptive aggressive decisions in social conflicts given their threat
sensitivity, cognitive functions, and learning experience. We plan to present
mathematically well-defined aggressive decision scenarios to healthy
participants as well as patients across diagnostic categories with high scores
of aggressive behavior, threat sensitivity, and inference of hostile intent in
others. Computational models that accurately explain behavioral choices and
neural responses (tested using fMRI and pupillometry) will be developed to
identify the aggressive decision strategies humans employ in approach-avoidance
conflicts of increasing complexity and ecological realism. The purpose will be
to determine if patients use overly aggressive strategies that are not warranted
by the necessary defense of self-threats and underlying neural circuits.

Investigate context-dependent aggression triggered by frustrative
non-reward or acute social threats. Using newly developed approaches, multiple behavioral domains will be assessed in
a semi-naturalistic, autonomous mouse habitat. Specifically, the habitat assesses the inter-individual dynamics of social
interactions, aggressions, and hierarchy and the individual reward learning and impulsivity through different integrated
modules. Intermittent challenges comprise intruder aggression and frustrative non-rewards. Within this LCD, circuit
mechanisms are dissected through chemogenetic interventions, in vivo recordings, and functional MRI in awake mice
during task performance. This approach in the first funding period will enable us to disentangle the specific functions of
candidate entry points in prefrontal to ventral striatum pathways with respect to their modulation of aggression and
dominance for potential interventions.

Address sex-specific NVS (reactive aggression) and CS (different dimensions of psychopathy, proactive aggression) associated risk factors, and risk factor-based biosignatures in young people. Considering the interacting genetic, environmental, and hormonal factors related to these specific aggressive behavior dimensions, C04 will identify specific and shared factors and mechanisms related to
NVS and CS in female and male youth with and without pathological aggression. Implementing deep-learning algorithms, sex-specific, data-driven subgroups in relation to dimensions of aggressive behavior will be described and probed against the NVS and CS. Group-level risk factors of aggressive behavior dimensions, and individual risk factor-based subgrouping will be the basis of developing a biologically informed stratification strategy for tailored treatment. Models and classifiers will be established cross-sectionally in available data and replicated in the prospectively collected cross-sectional data (Q01). In addition, C04 will test the models and classifiers for predictive validity in the longitudinal data of the TRR Q01 cohort.

Link questionnaire measures of aggression to specific neural
substrates using structural MRI. The resulting patterns of aggression-related neuroanatomical variability will be co-
registered with the Allen Human Brain Atlas providing gene-expression data, to highlight genes with a spatial pattern
of expression that matches the neuroimaging findings. Utilizing the neurotypical control data, a normative model of
neuroanatomical diversity within the NVS and CS will be established to quantify neuroanatomical abnormalities within
these systems in individual cases

Identify specific neuronal mechanisms related to the NVS
and CS in female and male clinical samples with a history of early-life maltreatment (ELM) who exhibit externalizing,
aggressive psychopathologies as opposed to internalizing, non-aggressive psychopathologies. We will therefore explore
the interaction of the NVS and CS as well as the modulating effects of theory-of-mind (ToM) on the NVS and CS using a
series of fMRI and behavioral tasks. Furthermore, we will investigate the role of hormonal stress responses and will
use EMA to assess anger and aggression in everyday life. Thus, we will be able to combine behavioral phenotyping in
natural conditions of everyday life and neurobiological correlates of psychopathology in order to detect clinically relevant
biosignatures for AMD.

Test the interaction of the CS and frustrative non-reward as part of the NVS. It will investigate the electrophysiological
correlates of frustrative feedback in aggression-prone patients. In the aftermath of induced stress, an EEG task-battery
including frustrative feedback will be applied for extraction of error-related negativity (ERN) and contingent negative
variation to monitor electro-physiologic signaling of the relevant learning and frustration processes. In half of the
participants, tDCS over the prefrontal cortex will be applied to enhance cognitive control, with participants being put into
a stress context inducing frustration.
