About the Wallis Lab

We are part of the Department of Psychology and Helen Wills Neuroscience Institute at the University of California at Berkeley. Our research focuses on understanding the functional organization of the frontal cortex at the single neuron level. Our methods use sophisticated behavioral paradigms, multichannel recording and computational analysis of neuronal data. We aim to understand the neuronal mechanisms underlying a number of high-level cognitive and behavioral processes, including decision-making, learning and working memory. The goal of our research is to guide the development of the next generation of treatments for mental illness.

Recent news

Nov 2017: Our collaboration with Dr. Jose Carmena uses microstimulation of the caudate nucleus to change an animal's decisions. The paper was published in Current Biology.

Oct 2017: Erin published a paper in Nature Communications examining the relationship between high gamma and single neuron activity in orbitofrontal cortex.

May 2017: Our newest member of the lab is Zuzanna Balewski, who is a HWNI graduate student. She will be studying how learning affects the representation of decision spaces in orbitofrontal cortex.

Apr 2017: Erin has started her own lab at the Ichahn School of Medicine at Mount Sinai where she will be studying (among other things) why we like bagels.

Oct 2016: Our collaboration with Dr. Laurence Hunt at Univeristy College London shows that different functional classes of orbitofrontal neurons have different autocorrelational structure. The paper was published in eLIFE.

May 2016: Erin published a paper showing how subjective decisions can be decoded from brain activity in Nature Neursocience.

Mar 2016: Congratulations to Erin who has accepted an Assistant Professor position at Mount Sinai.

Jan 2016: Eric was awarded an R21 to study how electrical stimulation can modify value judgments.

Dec 2015: Our paper studying the dynamics of local field potentials in decision-making was published in eLIFE.

May 2015: Erin was awarded a K08, scoring in the top 1% of all grants.

Dec 2014: Our collaboration with Dr. Xiao-Jing Wang at NYU shows that the timescale of intrinsic neural fluctuations lengthens in higher cortical areas. The paper was published in Nature Neuroscience.

Sep 2014: The lab has been awarded an R21 to examine whether prediction errors in the anterior cingulate cortex are dopamine-dependent.

Jun 2014: Eric Knudsen joined our lab as a postdoctoral fellow. Eric did his Ph.D. with Dr. Karen Moxon in the Neurorobotics Lab at Drexel University.

May 2014: Our lab is part of a team that has been selected by DARPA to build brain implants for the treatment of neuropsychiatric disease. Further details can be found here:
