    Acetylcholinergic Drug enhances attention at different dose as cognitive flexibility

    Acetylcholinergic Drug enhances attention at different dose as cognitive flexibilityWe tested how a cholinergic drug that is used to treat symptoms of dementia (donepezil, Arizept) affects cognitive abilities across multiple domains in monkeys. We found that donepezil showed stunning improvements of attentional filtering (less distraction) during visual search but at a different dose at it […]

    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 […]

    Adaptive Learning needs Attention, Meta-learning and Working Memory

    We tested which model mechanisms best explain how six animals learn attention sets and found a common set of most-important behavioral mechanisms that account for learning success.When learning attention sets is easy value based reinforcement learning and working memory are powerful, but when learning problems are more complex learning is more efficient with attention and […]

    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.

    Interneuron-specific gamma synchrony indexes uncertainty resolution

    Our new paper in eLife shows that a subclass of fast spiking interneurons in prefrontal and anterior cingulate cortex gamma synchronizes when uncertainty about cues and outcomes is resolved. This finding was possible by classifying narrow spiking neurons into fast and non-fast spiking classes and correlating their firing and spike-LFP synchrony during processing of attention […]
