A Novel Monkey Kiosk: Cognitive Enrichment and Cognitive Assessment

We now published the hardware and software design for a novel Monkey Kiosk Station that provides cognitive enrichment and the ability to assess cognition with cage-based touchscreen tasks. The paper and its appendix with the technical details are available here.

Fronto-Striatal Circuits Optimize Feature-based Attention and Learning

Our new publication (Oemisch et al. (2018) Feature Specific Prediction Errors and Surprise across Macaque Fronto-Striatal Circuits during Attention and Learning) provides the first 4-brain-area survey of how prediction error information in the anterior cingulate – ventral striatum and lateral prefrontal – caudate fronto-striatal loops relate to feature-based attention and learning. We found prediction errors […]

Effective Connectivity Shows Asymmetries in Resonance and Latencies between Medial and Lateral Prefrontal Cortex Connections

The lab has a first article published about the strength, latency and resonance patterns of connections between the anterior cingulate cortex and lateral prefrontal cortex of the macaque. This work was led by postdoc Veronica Nacher and is published in Brain Structure and Function. The paper identifies a novel electrical microstimulation protocol that can be […]

ACC causally supports learning -difficult- attention sets

We used focused ultrasound (FUS) sonication of the anterior cingualte and striatum to disrupt local processing during learning. FUS in ACC slowed down learning of atetntion sets – but only when the attentional demands were high and the task included the risk of loosing already attaiuned reward tokens. Under these cognitive and motivaitonally challenging conditions […]
