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.

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 […]
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..
We hosted a superb 2018 CPPC (Computational Properties of Prefrontal Cortex) Workshop at Vanderbilt. The workshop attracted more than 60 emerging and established (neuro-)scientists about how the prefrontal cortex works – See the program and more at the www link CPPC2018. This year had special sessions on value-based decision making and uncertainty, social cognition, functional […]
