Explore the Cognitive Rhythms & Computations Lab @ UNM!

In the CRCL lab directed by Dr. James F. Cavanagh at the University of New Mexico in Albuquerque, NM, we investigate questions of cognitive change and functions using brain imaging techniques such as EEG, MRI, and MEG.

Areas of Interest

Reward

The Reward Positivity (RewP) is an event-related potential component specifically evoked by positively valenced feedback.

Frontal Theta

Our work in this field began in 2009 with the theoretical model of theta power signaling the need for control and theta phase synchrony communicating the implementation of control.

Rodent - Human Translation

Electrophysiology is a promising common denominator for translational research. We test mechanistic hypotheses in rodents that are relevant for human clinical biomarkers.

Multimodal Imaging

We combine EEG with multi-modal imaging (MEG, MRI) for methodological breadth and with computational modeling for theoretical depth.

Goals vs Rewards: What We Can Learn from Positive Reinforcement

"James Cavanagh, a professor at The University of New Mexico, joins It’s (Probably) Not Rocket Science to discuss his recently published theoretical review about the Reward Positivity brain signal and its role in linking high level control and low-level rewards processes together. Cavanagh worked alongside Clay B. Holroyd from Ghent University on the review, which was funded by a grant looking into anhedonia—the decreased ability to experience pleasure as it relates to clinical depression."

EEG signatures provide evidence for a
shrinking spotlight of attention after errors

"Errors inhibit attainment of our goals, but there are many ways to get back on track: from increased caution to heightened attention. In this report we examined EEG signatures of control and perception in 21 participants who completed a luminance-varying flanker task. [...] Perceptual changes elicited by the luminance manipulation scaled with posterior alpha/beta power; both these extrinsic and intrinsic features loaded on an enhanced drift rate. Most importantly, after an error, this relationship between alpha/beta power and drift rate was enhanced. These findings support separate roles of neural systems in adaptive control: mid-frontal regions were linked to generic control, whereas sensory-specific mechanisms of attentional adjustment were specifically recruited to boost evidence accumulation when control is needed."
