Sensory perception triggers an information/energy exchange with the environment, but the brain’s recurrent activations maintain a resting state with constant parameters. Therefore, perception forms a closed thermodynamic cycle. In physics, the Carnot engine is an ideal thermodynamic cycle that converts heat from a hot reservoir into work, or inversely, requires work to transfer heat from a low- to a high-temperature reservoir (the reversed Carnot cycle). We analyze the high entropy brain by the endothermic reversed Carnot cycle. Its irreversible activations provide temporal directionality for future orientation. A flexible transfer between neural states inspires openness and creativity. In contrast, the low entropy resting state parallels reversible activations, which impose past focus via repetitive thinking, remorse, and regret. The exothermic Carnot cycle degrades mental energy. Therefore, the brain’s energy/information balance formulates motivation, sensed as position or negative emotions. Our work provides an analytical perspective of positive and negative emotions and spontaneous behavior from the free energy principle. Furthermore, electrical activities, thoughts, and beliefs lend themselves to a temporal organization, an orthogonal condition to physical systems. Here, we suggest that an experimental validation of the thermodynamic origin of emotions might inspire better treatment options for mental diseases.}, year = {2022}, eissn = {1099-4300}, pages = {1498} } @CONFERENCE{MTMT:32863677, title = {Dendritic synaptome of GABAergic interneurons in the mouse visual cortex}, url = {https://m2.mtmt.hu/api/publication/32863677}, author = {Talapka, Petra and Nóra, Gargya and Kocsis, Zsolt and Vera, Etelka Szarvas and Kisvárday, Zoltán}, booktitle = {International Neuroscience Meeting, Budapest 2022}, unique-id = {32863677}, year = {2022}, pages = {109} } @article{MTMT:32863612, title = {Application of the mirror technique for block-face scanning electron microscopy.}, url = {https://m2.mtmt.hu/api/publication/32863612}, author = {Talapka, Petra and Bába, Bence Béla and Mészár, Zoltán and Kisvárday, Réka Eszter and Kocsis, Zsolt and Srivastava, Mohit and Kisvárday, Zoltán}, doi = {10.1007/s00429-022-02506-w}, journal-iso = {BRAIN STRUCT FUNC}, journal = {BRAIN STRUCTURE & FUNCTION}, volume = {227}, unique-id = {32863612}, issn = {1863-2653}, abstract = {The mirror technique adapted for electron microscopy allows correlating neuronal structures across the cutting plane of adjoining light microscopic sections which, however, have a limited thickness, typically less than 100 µm (Talapka et al. in Front Neuroanat, 2021, https://doi.org/10.3389/fnana.2021.652422 ). Here, we extend the mirror technique for tissue blocks in the millimeter range and demonstrate compatibility with serial block-face electron microscopy (SBEM). An essential step of the methodological improvement regards the recognition that unbound resin must be removed from the tissue surface to gain visibility of surface structures. To this, the tissue block was placed on absorbent paper during the curing process. In this way, neuronal cell bodies could be unequivocally identified using epi-illumination and confocal microscopy. Thus, the layout of cell bodies which were cut by the sectioning plane can be correlated with the layout of their complementary part in the adjoining section processed for immunohistochemistry.

We have developed an immunohistochemistry (IH)-correlated electron microscopy (EM) method – the “mirror” technique – by which synaptic input to entire dendrites of neurochemically identified interneurons (INs) can be mapped due preserving high-fidelity tissue ultrastructure. Hence, this approach allows quantitative assessment of morphometric parameters of synaptic inputs along the whole length of dendrites originating from the parent soma. The method exploits the fact that adjoining sections have truncated or cut cell bodies which appear on the common surfaces in a mirror fashion. In one of the sections the histochemical marker of the GABAergic subtype, calbindin was revealed in cell bodies whereas in the other section the remaining part of the very same cell bodies were subjected to serial section EM to trace and reconstruct the synaptology of entire dendrites. Here, we provide exemplary data on the synaptic coverage of two dendrites belonging to the same calbindin-D28K immunopositive IN and determine the spatial distribution of asymmetric and symmetric synapses, surface area and volume of the presynaptic boutons, morphometric parameters of synaptic vesicles, and area extent of the active zones.}, year = {2021}, eissn = {1662-5129} } @article{MTMT:31935779, title = {The thermodynamics of cognition: A mathematical treatment}, url = {https://m2.mtmt.hu/api/publication/31935779}, author = {Déli, Éva Katalin and Peters, James and Kisvárday, Zoltán}, doi = {10.1016/j.csbj.2021.01.008}, journal-iso = {CSBJ}, journal = {COMPUTATIONAL AND STRUCTURAL BIOTECHNOLOGY JOURNAL}, volume = {19}, unique-id = {31935779}, issn = {2001-0370}, year = {2021}, eissn = {2001-0370}, pages = {784-793} } @CONFERENCE{MTMT:31905631, title = {High-resolution retinotopic mapping with optical imaging of intrinsic signals in cat primary visual cortex}, url = {https://m2.mtmt.hu/api/publication/31905631}, author = {Kocsis, Zsolt and Mohit, Srivastava and Julian, ML Budd and Cyril, Monier and Yves, Fregnac and Kisvárday, Zoltán}, booktitle = {IBRO Workshop}, unique-id = {31905631}, year = {2020}, pages = {14} } @article{MTMT:31621004, title = {Prophylactic, single-drug cardioprotection in a comparative, experimental study of doxorubicin-induced cardiomyopathy}, url = {https://m2.mtmt.hu/api/publication/31621004}, author = {Lódi, Mária and Bánhegyi, Viktor and Bódi, Beáta and Gyöngyösi, Alexandra and Kovács, Árpád and Árokszállási, Anita and Hamdani, Nazha and Fagyas, Miklós and Édes, István and Csanádi, Zoltán and Czuriga, István and Kisvárday, Zoltán and Lekli, István and Bay, Péter and Tóth, Attila and Papp, Zoltán and Czuriga, Dániel}, doi = {10.1186/s12967-020-02564-w}, journal-iso = {J TRANSL MED}, journal = {JOURNAL OF TRANSLATIONAL MEDICINE}, volume = {18}, unique-id = {31621004}, issn = {1479-5876}, year = {2020}, eissn = {1479-5876}, orcid-numbers = {Czuriga, Dániel/0000-0002-6972-0781} } @article{MTMT:31618887, title = {The thermodynamic brain and the evolution of intellect: the role of mental energy}, url = {https://m2.mtmt.hu/api/publication/31618887}, author = {Déli, Éva Katalin and Kisvárday, Zoltán}, doi = {10.1007/s11571-020-09637-y}, journal-iso = {COGN NEURODYN}, journal = {COGNITIVE NEURODYNAMICS}, volume = {14}, unique-id = {31618887}, issn = {1871-4080}, year = {2020}, eissn = {1871-4099}, pages = {743-756} }
