New discovery – brain waves that coordinate formation of human memories

We are delighted to share with you about the recent publication of our research findings, which appeared this month in the journal NeuroImage. It is a result of almost 4 years of our work on mapping the brain waves generated in our brain as memories for words are formed. Tory Marks, a PhD student of biomedical engineering at Mayo Clinic, worked together with other members of our BME lab on a large dataset of over 150…

HOW DIRECT BRAIN STIMULATION AFFECTS LOW (THETA) AND FAST (GAMMA) NEURAL ACTIVITIES? NEW RESEARCH ARTICLE FROM OUR BME LAB

What happens in the brain when it is stimulated with electric current? Can we see a link between the human brain behavior during stimulation and during enhanced memory performance? In our latest article which will be published in the open-access journal IEEE Transactions on Biomedical Engineering we addressed these questions using brain recordings from epilepsy patients stimulated with electric current during quiet wakefulness. In a fraction of electrode sites in the brain (1.4% on average),…

Can post-comatose minimally conscious patients read? A new study by the member of our BME lab assesses with eye-tracking technology.

Dr. Michal Lech, postdoc in our BME lab, in his recent Scientific Reports publication with Dr. Agnieszka Kwiatkowska, Dr. Piotr Odya, and Prof. Andrzej Czyżewski from the Department of Multimedia Systems of the Gdansk University of Technology, found that the post-comatose patients with minimal consciousness tend to preserve reading comprehension skills but neglect syntax and spelling. Their results showed that most patients preserved the ability to read one- and two-syllable words and comprehended sentences but…

New BME lab video is going to show how the brain memorizes words!

Theodore Thayib joined our BME lab as a summer undergrad student to help us with a challenging task to visualize brain activity collected from over 150 patients remembering lists of words. Theo’s skills and talents in computer sciences, which he studies as major at the Iowa State University, enabled us to follow the brain waves that underlie thinking and memorizing words across multiple dimensions of the 3D brain anatomy, time of word presentation, and six different…

Our article is in the top 100 neuroscience Scientific Reports papers in 2018

It is our great pleasure to announce that our recent discovery published in the article entitled: ‘Pupil size reflects successful encoding and recall of memory in humans’ received over two thousand article views in 2018, placing it as one of the top 100 read neuroscience papers for the Nature group journal Scientific Reports. The journal published more than 1600 neuroscience papers in the same year. In the article, we showed by taking careful measurements of the pupil size in the eyes…

Members of the BME lab published their new paper about assessing consciousness with eye-tracking

Members of the BME lab, Michal Lech and Michal Kucewicz, have just published a paper in Frontiers in Neurology with Prof. Andrzej Czyżewski from the Multimedia Systems Department of Gdansk University of Technology’ entitled: ‘Human Computer Interface (HCI) for tracking eye movements improves assessment and diagnosis of patients with acquired brain injuries’. In the paper, we show that our HCI interface called ‘Cyber Eye’, which was developed by Prof. Czyżewski’s team, can detect minimally conscious…
