Postdocs

Paloma Díaz-Gutiérrez

I completed my Master's degree in Cognitive and Behavioural Neuroscience at the University of Granada, where I am currently a PhD student. My research focuses on the use of behavioural and fMRI techniques to study the underlying basis of cognitive control mechanisms during social decisions and how social information is represented in the brain, depending on the context. In my free time I force myself to go to the gym, but what I really do is binge-watching TV shows. I am also a former flutist who owns a piano, a guitar and an ukelele, but can play none. Potterhead.

Graduate students

David López-García

I am Telecommunication Engineer and PhD student at the University of Granada. I have worked in the study of automatic detection and classification of sleep disorders by analyzing patients’ EEG. Now, my PhD focuses on the analysis of brain functional Magnetic Resonance images and High Density Electroencephalography by the implementation and optimization of several signal processing techniques. I also try to play tennis in my spare time. Email

Alberto Sobrado

I am a PhD student, with a background of psychology and cognitive neuroscience. My thesis seeks to study how cognitive control allows humans to prepare and achieve novel behaviors at the first attempt and the factors involved in this process, using behavioral and fMRI measures. Love coffe. Email

Chema G. Peñalver

I have just started my PhD at the University of Granada, where I also completed my Master’s degree on Cognitive and Behavioral Neuroscience. On my thesis I’m focusing on understanding the mechanisms of preparation, and how they differ through different cognitive contexts. For that, I’m interested in the combined use of different research tools, such as fMRI and EEG. I’m a scout, so I spend my free time either hiking or volunteering as a camp monitor. Besides, I love origami and going to the movies whenever I can. Email

Research

Neural mechanisms underlying the strategic and automatic effects of affective information on interpersonal decision-making

Funded by the Spanish Ministry of Science (PSI2013-45567-P)

Read more

With this project we aim to increase our knowledge about the neural structures that support human decision-making in social contexts involving interactions with other people. We employ neuroimaging methods (magnetic resonance imaging, MRI and high-density electrophysiology) in healthy populations with a twofold objective. On the one hand, we study the neural circuits that support the strategic use of other peoples emotional facial expressions to predict their future behavior, and on the other hand, the brain areas that respond to this affective information in a ballistic manner influencing responses automatically. We also study how individual differences in trait anxiety impact interpersonal decision-making and will measure the extent to which unconscious affective information biases our cooperative decisions, and the underlying brain regions.

Neural mechanisms of cognitive control during the preparation and implementation of novel tasks

Funded by the Spanish Ministry of Science (PSI2016-78236-P)

Read more

Cognitive control is a core skill of humansas it allows us to adapt to changing situational demands in a fast, efficient and highly flexible manner. This project aims at studying the neural mechanisms involved in the preparation to perform novel tasks and their implementation, while considering the links between the control mechanisms involved in these phenomena and their motivational counterpart, and in relation to the effort that classic and modern conceptions associate to control.

Research facilities

Our lab is located at the Mind, Brain and Behavior Research Center. Here we have access to several behavioral testing rooms, a 3T Siemens Magnetic Resonance Imaging facility with compatible EEG and EyeLink Eyetracker, high-density EEG recording devices, and a Transcranial Magnetic Stimulation device with a robotic assistant and neuronavigator.
