We have recently identified a group of claustral neurons that continuously maintain information associated with fear-conditioned stimulus (CS) for at least tens seconds, even after the CS has ceased. This “online state” refers to persistent maintenance threat-associated information, enabling it be actively processed threat terminated. state may involve reciprocal interactions brain regions involved in decision-making, motor preparation, and adaptive behavioral responses. If these truly encode online state, their function should remain independent modality or specific defensive behavior exhibited. In this study, we used tone cue monitored freezing trace conditioning, contrast light escape our recent study. During retrieval test subset rostral-to-striatum claustrum (rsCla) exhibited sustained activity response CS, particularly during interval. Importantly, found positive correlation between rsCla magnitude interval, when intervals without were excluded. Thus, appears exhibit characteristics ‘online neurons’ memory following conditioning.

The claustrum (CLA) is a conspicuous subcortical structure interconnected with cortical and regions. Its regional anatomy cell-type-specific connections in the mouse remain not fully determined. Using multimodal reference datasets, we confirmed delineation of CLA as single group neurons embedded agranular insular cortex. We quantitatively investigated brain-wide inputs outputs using bulk anterograde retrograde viral tracing data neuron data. found that prefrontal module has more cell types projecting to than other modules, layer 5 IT predominating. nine morphological principal topographically innervate functionally linked targets, preferentially midline areas, secondary motor area, entorhinal area. Together, this study provides detailed wiring diagram CLA, laying foundation for studying its functions at cellular level.

The claustrum is a small nucleus, exhibiting vast reciprocal connectivity with cortical, subcortical, and midbrain regions. Recent studies, including ours, implicate the in salience detection attention. In current study, we develop an iterative functional investigation of claustrum, guided by quantitative spatial transcriptional analysis. Using this approach, identify circuit involving dopamine-receptor expressing claustral neurons projecting to frontal cortex necessary for context association reward. We describe recruitment cocaine their role drug sensitization. order characterize within which these are embedded, apply chemo- opto-genetic manipulation increasingly specified subpopulations. This strategy resolves defined network dopamine D1 receptors acquisition conditioned-place preference real-time optogenetic preference. sum, our results suggest claustrum-to-frontal attribution incentive salience, allocating attention reward-related contextual cues.

Persistent pain is a prevalent medical concern correlating with hyperexcitable anterior cingulate cortex (ACC). Its activity modulated by inputs from several brain regions, but the maladjustments that these afferent circuits undergo during transition acute to chronic still require clarification. We focus on ACC-projecting claustrum (CLAACC) neurons and their responses sensory aversive stimuli in mouse model of inflammatory pain. Using chemogenetics, vivo calcium imaging, ex electrophysiological approaches, we reveal suppression CLAACC acutely attenuates allodynia preferentially transmits information ACC. With prolonged pain, claustro-cingulate functional impairment develops, which mediated weakened excitatory drive onto ACC pyramidal neurons, resulting diminished claustral influence These findings support an instrumental role processing nociceptive its susceptibility persistent states.

Abstract The claustrum has been linked to attention and sleep. We hypothesized that this reflects a shared function, determining responsiveness stimuli, which spans the axis of engagement. To test hypothesis, we recorded population dynamics from male mice during both sleep an attentional task (‘ENGAGE’). Heightened activity in neurons projecting anterior cingulate cortex (ACCp) corresponded reduced sensory Similarly, ENGAGE task, heightened ACCp correlated with disengagement behavioral lapses, while low hyper-engagement impulsive errors. Chemogenetic elevation awakenings errors task. Furthermore, employing exploration strategy showed stronger correlation between performance compared exploitation complexity. Our results implicate restricting engagement goal-directed behavior.

Claustrum orchestrates brain functions via its connections with numerous regions, but molecular and cellular organization remains unresolved. Single-nucleus RNA sequencing of 227,750 macaque claustral cells identified 48 transcriptome-defined cell types, most glutamatergic neurons similar to deep-layer insular neurons. Comparison macaque, marmoset, mouse transcriptomes revealed macaque-specific types. Retrograde tracer injections at 67 cortical 7 subcortical regions defined four distinct distribution zones retrogradely labeled Joint analysis whole-brain connectivity single-cell spatial transcriptome showed that these containing compositions (but not GABAergic) types preferentially connected specific a strong ipsilateral bias. Several in ventral vs. dorsal selectively co-projected two functionally related areas-entorhinal cortex hippocampus motor putamen, respectively. These data provide the basis for elucidating neuronal underlying diverse functions.

The claustrum is densely connected to the cortex and participates in brain functions such as attention sleep. Although some studies have reported widely divergent organization of projections, others describe parallel claustrocortical connections different cortical regions. Therefore, details underlying how neurons broadcast information networks remain incompletely understood. Using multicolor retrograde tracing we determined density, topography, co-projection pattern 14 pathways, mice. We spatially registered these pathways a common coordinate space found that system topographically organized series overlapping spatial modules, continuously distributed across dorsoventral axis. core projects predominantly frontal-midline regions, whereas dorsal ventral shell project motor temporal lobe, respectively. Anatomically regions receive input from subset shared by neighboring separated are innervated modules. each output module exhibits unique position within overlaps substantially with other modules projecting functionally related Claustrum inhibitory cells containing parvalbumin, somatostatin, neuropeptide Y also show topographical distributions, suggesting controlled distinct circuit motifs. topographic excitatory cell types may enable outputs independently networks.

SUMMARY In various mental disorders, dysfunction of the prefrontal cortex contributes to cognitive deficits. Here we studied how claustrum (CLA), a nucleus sharing reciprocal connections with cortex, may participate in these impairments. We show that specific ensembles CLA and medial (mPFC) neurons are activated during task requiring control such as attentional set-shifting, i.e. ability shift attention towards newly relevant stimulus-reward associations while disengaging from irrelevant ones. exert direct excitatory input on mPFC pyramidal cells, chemogenetic inhibition suppresses formation assemblies set-shifting. Furthermore, impairing recruitment through opto/chemogenetic manipulations prevents conclusion, propose controls reorganization enable emphasizing potential role CLA-mPFC network dysfunctions.
