Research profile:


Laboratory of Brain Imaging (LOBI) is one of the core facilities at the Neurobiology Center. LOBI provides access to state-of-the-art research support and technologies for internal and external scientists. Technologies used at LOBI include: magnetic resonance imaging (MRI), spectroscopy (MRS), electroencephalography (EEG - including EEG-fMRI simultaneous recordings), transcranial magnetic stimulation (TMS) and computational image analysis.

Research at LOBI has made fundamental contributions to the understanding of the neural processes responsible for cross-modal neuroplasticity in healthy and deaf people, neuronal mechanisms of consciousness, processing of emotionally charged information in healthy and  subclinical  populations  as  well  as  analytic  approaches  for  multisite  MRI  data of developmental and neurological disorders.

Additionally, LOBI develops standardized databases of stimuli to facilitate highly controlled experimental research on emotion and cognition - Nencki Affective Picture System (1356 images) and Nencki Affective Word datasets (2902 Polish words). Stimuli in both datasets are characterized in terms of emotional valence, arousal, as well as basic emotion intensities. The NAPS and NAWL databases are freely accessible to the scientific community ( More information can be found on the web page:


Current research activities:


• Brain plasticity in language acquisition. The aim of the project is to reveal a multimodal brain network for speech and print in a second language. Adopting a longitudinal design, we test learners of foreign languages, sign language and Braille reading. Besides distin- guishing which structures of the language-processing network are multimodal and which are not, we plan to examine the dynamic changes in the brain morphology and function associated with linguistic learning.

• Neuronal mechanisms of consciousness. We develop two lines, first we study how brain activity differs between unconscious (e.g. sleep, anesthesia) and conscious states. Second, we try to address which mechanisms allow external stimuli to gain access to our subjective “stream of consciousness”.

• Neural correlates of procrastination. Using cognitive tasks in emotional contexts during fMRI experiments we try to get neuronal-level insight into  mechanisms of this self-regulatory failure.

• Influence of emotions of long-term and associative memory

• Directed forgetting of emotionally charge material using NAWL

• Neural markers of dyslexia.
