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.

First Neuropharmacological Contribution
Congratulations to Ali and Mariann for the first neuropharmacological contribution from our laboratory with the article A computational psychiatry approach identifies how alpha-2A noradrenergic agonist Guanfacine affects feature-based reinforcement learning in the macaque . This study first surveys all 14 different tasks that have ever been used with Guanfacine in nonhuman primate studies and than […]
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 […]
