ANA F. PALENCIANo
PI
I did my PhD at the Mind, Brain, and Behavior Research Center with Maria Ruz, exploring how the brain flexibly encodes novel, instructed demands. I continued deepening on that field while working as a postdoc at Ghent University, in Marcel Brass’ and Baptist Liefooghe’s labs. Now I am a postdoc researcher at the University of Granada. In general terms, I’m interested in studying neural task representations using fMRI/EEG and multivariate analyses.
RODIKA SOKOLIUK
PI
I am a Ramón y Cajal fellow based in Granada. I did my PhD with Rufin VanRullen in Toulouse (France), followed by a postdoc with Simon Hanslmayr, Karen Mullinger and Stephen Mayhew in Birmingham and Nottingham (UK). I then pursued a second postdoc at the Centre of Human Brain Health in Birmingham with Damian Cruse, before I relocated to Berlin (Germany) to work with Surjo Soekadar and Andrea Kühn at the Charité University Hospital. My current research interests blend what I have learnt during my research journey, straddling the line between basic and applied research. Combining electrophysiology with cognitive paradigms, I aim to improve diagnostic and prognostic accuracy in unresponsive patients with disorders of consciousness.

MSc Neuroscience — Phd Student
I am a PhD student at the University of Granada, where I also completed a master’s degree in Cognitive and Behavioral Neuroscience. My research focuses on the neuro-cognitive mechanisms that underlie the modulation that social expectations have on the perception of other people. To this end, we combine behavioral measures such as mouse movements with neural recordings such as EEG and fRMI. I use my free time for climbing, music and friends, not forgetting my lovely kitty.

I am a PhD student at the University of Granada, co-supervised by María Ruz & Christopher Summerfield. I have a dual Bachelor’s degree in biomedical engineering and chemical & biological engineering from Colorado State University, where I was an undergraduate researcher in a cognitive neuroscience lab working on multimodal fusion of neuroimaging data and machine learning. Loosely, I’m interested in neuroimaging and AI and using computational methods to model and investigate cognitive processes in the human brain. Outside of research I love cooking, the outdoors, and music!
Johannah Voeller

I am a PhD student at the University of Granada, co-supervised by Carlos González García & Juan Linde Domingo. During my PhD, I study how we learn new information in a single instance, focusing on the contribution of different memory systems to retaining this information over time. Previously, I completed my MSc in Psychology at the University of Leipzig, Germany, during which I was a research assistant at the Max Planck Institute for Human Cognitive and Brain Sciences under the supervision of Prof. Dr. Doeller. Outside of everything brain-y I love arts & crafts, the outdoors, and fries!

Research
Characterization of the brain mechanims of preparation in contexts of Selective Attention
Funded by the Spanish Ministry of Science — PID2019-111187GB-I00
Preparing in advance for upcoming challenges provides a key behavioral advantage for the efficiency of human behavior across a wide range of contexts. Theoretical models in Cognitive Neuroscience have associated this ability with proactive, top-down endogenous modulation of brain activity. Research indicates that preparation generates the representation of task goals in high-level associative brain areas, which bias activations in lower-level perceptual regions in anticipation of target presentation. Collectively these preactivations carry specific information about the advanced scenarios, including the category of the target stimuli. Despite its core importance in cognitive brain functioning, to date we lack an understanding of how these preparatory mechanisms are flexibly tuned to help meet the demands posed by different contexts, and the extent to which they follow compositionality principles where simpler mechanisms are used to build more complex ones.
The general goal of the current project is to fill this gap by employing cue-target experimental paradigms during functional Magnetic Resonance (fMRI) and Electroencephalographic (EEG) recordings in humans. Each fMRI and EEG experiment will be analyzed with multivariate pattern methods, in combination with classic univariate approaches. This will allow characterizing the information contained in preparatory activations linked to contexts of increasing complexity, its temporal dynamics and its relevance for the efficiency of behavioral performance. Overall, the results of the experimental series will have a significant impact on the fields of Cognitive Control and Selective Attention, advancing our knowledge about the characteristics of neural endogenous preparatory activity in different contexts. Additionally, our findings will be highly informative regarding the extent to which these anticipatory mechanisms are compositionally built across domains of different complexity.
Neural coding of information for proactive cognitive control
Funded by the Spanish Ministry of Science — PID2022-138940NB-I00
Ready, Steady, Go! It is common lay knowledge that preparing in advance improves the efficiency of behavior. Why and how this happens, however, is still far from being understood. One of the research fields that can provide highly valuable insights to advance this knowledge is the study of information coding in the human brain. The present project will test the overarching hypothesis that anticipatory activations reflect a form of internal control of brain circuit dynamics that brings cortical states closer to the representational subspace that matters for the upcoming task. We will employ functional magnetic resonance (fMRI) and electroencephalography (EEG) neuroimaging combined with several multivariate analyses to investigate the spatio-temporal dynamics of the neural codes underlying advance preparation in the human brain.
