Professor Tomáš Čižmár, a researcher at the Leibniz Institute of Photonic Technology (Leibniz-IPHT) and professor at Friedrich Schiller University Jena, was awarded the prestigious Czech Minister of Education, Youth, and Sports Prize on November 19, 2024. The award recognizes his pioneering work in developing a holographic endoscope for brain research—an innovation he also advances as the head of the “Complex Photonics” group at the Institute of Scientific Instruments of the Czech Academy of Sciences in Brno.
The holographic endoscope developed by Čižmár and his international team employs optical fibers as thin as a human hair, allowing researchers to investigate the brain with subcellular precision. This cutting-edge technology opens up unprecedented opportunities for neuroscientists to observe blood flow dynamics and neuronal activity deep within the brain in extraordinary detail.
These insights play a critical role in understanding and treating neurological disorders such as dementia. Furthermore, the technology enables repeated observation of brain structures in living animals, facilitating the study of brain functions in dynamic processes like social interaction, learning, and stress.
The endoscope delivers exceptional image quality, stability, and speed, essential for exploring the brain’s deepest regions. It provides continuous visualization of the entire brain depth and captures intricate details such as dendritic spines and subcellular vesicles. Additionally, it measures the activity of individual neurons and the blood flow in specific vessels. While the technology has so far been tested only on anesthetized animals, it already shows great promise for advancing in vivo neuroscience. Čižmár and his team have published the fundamental principles of this technology in leading scientific journals, including Nature and Science.
Interdisciplinary Expertise from Jena and Brno
Professor Čižmár’s research spans physics, neuroscience, and medical technology. At the Leibniz-IPHT, he leads the Fiber Optics Department, teaches waveguide optics at Friedrich Schiller University Jena, and heads the “Complex Photonics” group at the Institute of Scientific Instruments of the Czech Academy of Sciences in Brno. His interdisciplinary approach demonstrates how foundational research and technological innovation can address critical societal challenges.
From Research to Application: DeepEn
In addition to his academic work, Čižmár serves as a scientific advisor to DeepEn, a spin-off of the Leibniz-IPHT. DeepEn designs ultra-thin endoscopes for minimally invasive examinations of hard-to-reach areas of the body. With subcellular resolution, these instruments support the study of neurological diseases and contribute to the development of new therapies. DeepEn has received several accolades for its innovative solutions and is currently a finalist for the Audience Award in the Thüringer Innovation Prize competition.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
