Phase-specific Activation Induces Latent Connectivity Changes

A recent paper provides rare causal evidence that phase-specific stimulation during beta oscillation bursts lead to transient changes in effective (latent) connectivity. This finding and its potentially widespread implications are discussed in our paper Womelsdorf T, Hoffman K (2018) Latent Connectivity: Neuronal Oscillations Can Be Leveraged for Transient Plasticity. Current Biology. 28(16):R879-R882..

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 […]

Acetylcholine, Dopamine, and Glutamate measured in three brain areas with a new SPME-probe

Our new paper shows reliable Multi-Neuromodulator measurements in the awake nonhuman primate in prefrontal cortex, premotor cortex and the basal ganglia using a new chemical sensing probe. The probe uses principles of Solid-Phase-Microextraction and is a development by the SPME pioneer and collaborator Prof. Janusz Pawliszyn from the University of Waterloo. The paper can be […]
