Advanced ’microchip’ in the brain

Latest findings by Szeged researchers: intelligence could be determined by human-specific brain characteristics and, in turn, as the Achilles heels of the brain these could also be responsible for the development of certain brain disorders.

The neocortex is dedicated to higher-order cognitive functions such as language use. This part of the brain has a very similar microstructure in humans and in species used for animal tests. However, the latest results of two research groups in Szeged University, headed by Gábor Tamás and Karri Lamsa respectively, suggest that the human neocortical network has unique properties.


Gábor Tamás’s research group together with Zoltán Nusser (Institute of Experimental Medicine of the MTA) has published an article in eLife on the unique properties of excitatory and inhibitory neurons of the human cerebral cortex. These interneuron connections are so effective that a single action potential of a single neuron may activate several other neurons. The authors suppose that this property specific to the human cerebral cortex might have evolved in order to foster more effective information processing. The publication of Gábor Tamás and his colleagues shows that several synaptic vesicles release neurotransmitters owing to neural activity in these very effective interneuron connections. The cerebral cortex of other species does not exhibit a similar phenomenon, which entails the possibility that this has evolved in humans only.


Viktor Szegedi and Karri Lamsa (Department of Physiology, Anatomy and Neuroscience, University of Szeged) published an article in Plos Biology, which is closely connected to the topic above. The article claims that these very effective connections are rather flexible and plastic, i.e. their effectiveness can be more readily changed than that of the interneuron connections of rats, which were examined as a baseline. These strong interneuron connections can be changed due to learning, and thus are able to activate another neuron system in the human cerebral cortex. These results are also important because the regulation of the neocortical neural network is indispensable during higher-order cognitive functions, such as learning.

SZTE Experience

Hamza Baniata – Faculty of Science and Informatics

I am Hamza Baniata, a first-year student at the Doctoral School of Computer Science, and I am From Jordan. SZTE is continuously supporting research and it has an internationally recognized, highly ranked group of professors. It also offers courses and research topics that are strongly related to my research field; Cloud Computing, Fog Computing and Internet of Things. All of this motivated me to apply to the University/Department of Software Engineering. Szeged is a calm city, full of love and peace. The University of Szeged is similar to the city, which provides the perfect environment for creation and development. Studying at the university requires a high level of effort, commitment and seriousness. Applying to the university and having these characteristics are my two pieces of advice to prospective students. It is very early to define my future now, but I am planning to apply to a research position in my field after graduation and if I had the opportunity, I would love to contribute my effort and knowledge in advancing such a wonderful and respected university.

My name is Olney Rodrigues de Oliveira and I am from Brazil. I am currently pursuing my PhD studies in the Doctoral School of Education at SZTE. I chose the University of Szeged because it’s one of the best universities in Europe, especially in the field of education. I personally love Szeged because it is safe and I love the architecture, the cultural events, the local Market Mars Tér and so many other beautiful destinations. For my studies I wanted to have an excellent university in a good quality life city and Szeged offers me that. It’s neither too big nor too small, I can ride my bike to go to my classes and practically everything is within a walking distance. I would advise the prospective students to enjoy the city during their stay, the cultural and historical events, know other international students and make a lot of friends, visit other cities in Hungary and make good memories. I am pretty sure that you will be proud of this priceless experience. Before coming to Hungary I worked several years as a teacher. I love the academic environment, the libraries, relationship with students and the feeling to be involved in the acquisition of new knowledge. That is why I plan to be part of a University as a professor as well as to keep researching in different aspects of the process of education. I am so thankful to be here and I believe that the Universe brought me to Szeged because the city and the University are the experience that I need in my life now.
