Theta and Beta Frequency

Theta and beta frequency range coherence between anterior cingulate cortex and frontal eye field indexes the successful preparation for anti-saccades and maintenance of working memory content – with larger ACC to FEF direction of granger causal information flow! These important findings is now published in Nature Communications by Sahand Babapoor-Farrokhran and Stefan Everling with contributions from Martin Vinck and our lab – This is a particular important finding as neuronal coordination between prefrontal and anterior cingulate cortex at the identical frequency ranges characterize successful attention shifts and adjustments following errors – thus there is clear link of prefrontal attentional control signalling to the actual implementation of attentional selection in FEF (and parietal) networks – Congratulations for this major achievement !

New 3D-object type with controllable feature space published with open-sourced code

The lab has a new publication showcasing and describing details of Quaddles: A multidimensional 3D object set with parametrically-controlled and customizable features. Quaddles have 5+ feature dimensions, each with multiple possible feature values that can be parametrically morphed, making it possible to generate a near arbitrary number of unique objects.

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 […]

The phase of firing of fronto-striatal neurons encodes learning variables

Our new paper shows that neurons in the striatum, anterior cingulate and prefrontal cortex encode learning variables in the phase of firing. We outline a powerful regression based analysis pipeline that revealed spiking activity of neurons relative to the phase of beta oscillations carries significant learning information during reversal learning.
