His major goal is to provide rational, mechanistic explanations of cognitive functions at a descriptive level.
Over the past 35 years, Buzsaki has led the way in analyzing the functional properties of cortical neurons acting within their natural networks. He pioneered the experimental exploration of how coordinated, rhythmic neuronal activity serves physiological functions in the cerebral cortex, and in particular, how information is exchanged between the hippocampus and neocortex. For this aim, Buzsaki's lab has established some of the most difficult approaches necessary to solve these problems. His work includes innovative techniques to monitor neural activity and brain oscillation in behaving rodents from the cellular level to whole network activation.
In addition to his numerous publications and reviews, Gyorgy Buzsaki is the author of the book "Rhythms of the Brain", which discusses mechanisms and functions of neuronal synchronization. He explains the field of brain oscillations, and how oscillatory timing is the brain’s fundamental organizer of neuronal information. Among many other distinguished awards, he is the recipient of the 2011 European brain prize.

Plasma physics with intense heavy ion and laser beams is one of the important research pillows. The future Facility for Antiproton and Ion Research (FAIR), one of the largest research projects worldwide, will provide an unprecedented variety of experimental possibilities for all research directions including High Energy Density Physics.
Nowadays, before the FAIR start in 2020, the Petawatt High-Energy Laser System for Ion beam eXperiments – “PHELIX” with nanosecond and femtosecond frontends allows a variety of FAIR relevant experiments directed on creation and investigation of Warm Dense Matter.
In the talk, diagnostic methods using high resolved X-ray spectroscopy of the target K-shell radiation caused by laser accelerated electrons and heavy ions will be discussed.

Testing the MOND modified gravity in shell galaxies

They consist of the accreted stars reaching the apocenters of their orbits. Shells can be used to constrain the gravitational potential of their host galaxy up to the radius of around 100 kpc.
We developed the shell identification method for testing the compatibility of the observed shell radii in a galaxy with the given potential. While the method is also applicable for investigating dark matter halos, we have used it only to test the MOND modified gravity so far. We verified that MOND can explain the observed shell radii in a well studied shell galaxy NGC 3923 with the precision better than 5% (Bílek et al., 2013). Furthermore, MOND predicts the existence of a new shell at 1950" southwest from the galaxy's center (Bílek et al., 2014).
Shell spectral line profiles encode the information about the circular velocity at the position of the shell and the phase velocity of the shell itself (Ebrová et al., 2012). In Bílek et al. (2015), we found that these velocities are both expected to reach constant values at large radii in MOND, which is given by the baryonic mass of the galaxy. Their ratio can have only discrete values.

This nematic behavior is observed across many compounds and over a large part of the phase diagram of the material. What is this nematicity? Does it have any relationship to superconductivity in the material? In this talk I will attempt to answer these questions by providing a microscopic view of one of the pnictide compounds NaFeAs obtained using atomic-resolution scanning tunneling microscopy and spectroscopy. -

Max Planck Institute for Neurobiology, Munichמארגן המחלקה למדעי המוחצרו קשר תקציר Show full text abstract about Drosophila melanogaster flies show complex behaviors like as...» Drosophila melanogaster flies show complex behaviors like associative learning. Combining the available genetic tools with behavioral measures allows us to study the specific neuronal circuits of learning and memory.
Using olfactory conditioning, I directly compared the neuronal circuit of memories with different punishment paradigms: the widely used electric-shock and the newly established elevated temperature. I identified the neural pathway selectively required for olfactory-temperature conditioning, from the sensory input to the central neurons signaling reinforcement. I found that temperature and electric-shock punishments—despite being perceived by distinct sensors—eventually converge to the same neuronal network: the dopamine pathway. Thus the role of dopamine is general—attaching a motivational value to an environmental stimulus. This finding is especially significant in context of recent findings in mammalian systems, namely that in addition to their well-established role in signaling positive reinforcement, dopaminergic populations in the mammalian brain were also shown to represent aversive reinforcement.
