Principal Investigator

Jorge Almeida (BA, Psychology, University of Lisbon, 2003; MA, Psychology, Harvard University, 2008; PhD, Psychology, Harvard University, 2011)

I grew up in Lisbon, Portugal, where I received my BA in Psychology (2003; Faculty of Psychology, University of Lisbon). There I worked with Leonel Garcia Marques on topics of person perception, and Paulo Ventura on semantic memory. I then moved to Cambridge MA, USA, where I did my PhD (and MA) in Psychology at the Department of Psychology Harvard University (2011) with Alfonso Caramazza in the Cognitive Neuropsychology Laboratory and Ken Nakayama in the Vision Sciences Lab. I focused on the kinds of information that are processed unconsciously under continuous flash suppression, and on the processing of tools/manipulable objects. After my PhD I started working on the neural processing of tool items, focusing on how different types of tool-related information are processed in the brain and on how tool-related regions modulate the signal in other tool-related regions.

I am currently an Associate Professor at the Faculty of Psychology and Educational Sciences – University of Coimbra, Portugal. I am now focusing on how object-related information is mapped in the brain and how local object-selectively is defined within domain-specific networks via long-range connectivity. To do so I use fMRI, neuromodulation and behavioural testing. I am currently the PI or Co-PI in 4 FCT research projects, and the PI of the first ERC grant in the field of Psychology in Portugal – ContentMAP. My core research topics are cognitive neuroscience, object recognition, neural organization of conceptual knowledge, category specificity in the brain, neuroplasticity, and effects of neurostimulation on neural processing. To address these questions, I have the pleasure of collaborating with fantastic researchers around the world namely Bradford Mahon and the CAOs Lab now at Carnegie Mellon University; Angelika Lingnau at Regensburg University; Yanchao Bi and Fang Fang at Beijing Normal University and Peking University respectively; Mel Goodale and Jody Culham at Western University, among others.

Most importantly, I have been fortunate to have the help of an outstanding group of researchers at the Proaction Lab – you can meet them below!

Post-Doctoral Researchers

André Peres

André Peres holds a degree in Medical Physics from the University of São Paulo (2005), a Master's (2008) and PhD (2012) from the same University. He was a postdoctoral researcher at the Brain Institute - UFRN (2012-2016) and worked as an assistant professor at the Edmond and Lily Safra International Institute of Neurosciences - Santos Dumont Institute (2016-2019). Currently, he is a Junior Researcher at PROACTION Lab.

André's academic interests are centred on the dynamics of sensory processing, the integration between sensory systems and how environmental information is perceived by individuals. In human studies, he has used fMRI combined with machine learning techniques to understand how semantic categories are organized in the brain. In animal models, he used the electrophysiology technique with multi-electrode matrices. André has been also developing methods for brain stimulation as a neuronavigation system and protocols to assess the mismatch between the measured and nominal parameters of TMS. Find out more about him here.

Art Pilacinski

Art Pilacinski graduated in clinical psychology at Adam Mickiewicz University in Poznan, and worked on his Master’s project at Marceli Nencki Intitute of Experimental Biology in Warsaw, where he studied sex differences in implicit learning (also known as intuition), and executive impairments in Parkinson’s disease. From Warsaw he moved to Tuebingen, where he worked with Axel Lindner on action planning, as part of NOD/NoCo Lab, and established a prototyping lab (fablab) for the University of Tuebingen. In the Proaction Lab he is studying tool and action representations. He is generally interested in how the thoughts move the body and vice versa. You can find his personal page here.

Fredrik Bergström

Fredrik Bergström obtained his AS in Business Administration, AS in Philosophy, BSc in Cognitive Science, MSc in Psychology, and PhD in Cognitive Neuroscience (2016) from Umeå University (Sweden). After that, he was a postdoctoral researcher at the Proaction Lab, which focused on visual object recognition and how information is organized in the cortex. Currently, he is an independent researcher in the Proaction Lab and a Principal Investigator of an FCT research project, focusing on the effects of tDCS on functional brain networks, and the relationship between consciousness and visual object processing and visual short-term memory.

Fredrik’s main areas of interest are cognitive neuroscience and philosophy. He is interested in the relationship between consciousness and brain functions such as perception, action, attention, and memory. For example, what brain regions/mechanisms are necessary for different conscious experiences? To what extent can brain functions work without consciousness? Fredrik is using psychophysics, neuroimaging (e.g., fMRI), and neuromodulation techniques (e.g., tDCS) to address these topics.

Jon Walbrin

After completing his BSc in Psychology at Bangor University (Wales), Jon Walbrin joined the Developmental Social Vision Lab at Bangor with Dr Kami Koldewyn, where he completed an MSc in Neuroimaging, then PhD in Psychology. His PhD focused on using fMRI and MVPA approaches to investigate neural responses to dynamic social interactions, using a range of different dynamic stimuli (e.g. point-light figures, moving geometric shapes, and live-action videos)

Jon joined the PROACTION lab as a post-doc in March 2019, shortly after completing his PhD at Bangor University (Wales). During his post-doc, he hopes to use fMRI with MVPA approaches to investigate category-selective responses to tools, bodies, and human-tool interactions in the posterior temporal lobe, and wider brain.

Zohar Tal

Zohar Tal obtained her PhD in Neurobiology from the Hebrew University of Jerusalem (Israel). In her thesis, Zohar studied principles of topographic organization, focusing on the somatosensory and visual systems and their cross-modal correspondence.

This project included the application of different functional and structural MRI methods to characterize the neural correlates underlying urban behavioural adaptations of fruit bat pups during their first navigation experience.

Currently, Zohar is a postdoctoral fellow at the Proaction lab, and her main research focuses on the topographic organization of sensory information and higher cognitive functions. As part of the ContentMAP project, Zohar is using various phase-locked and population receptive field (pRF) methods to explore the topographic principles that govern the organization of object knowledge in the brain.
