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.

The former is based on observation of radar reflections from the plasma surrounding the core of an extensive air shower (EAS), while latter is based on detection of geomagnetic+Askaryan radiation produced as an EAS develops. Current status, calibration and future prospects will be presented. -

Elasticity of Random Networks and of Amorphous Solids

The analysis of these systems is complicated due to the presence of emerging disorder and vastly different interaction strengths between the constituents of these materials. In this talk, I will focus on the elasticity. More precisely I will look at spectral properties of random elastic networks and argue in which sense they provide a good toy model of disordered solids. Using the Cavity method, a sort of Bethe-Peierls iterative method, in the limit of small heterogeneities of the graph connectivity, I will derive approximate analytical expressions for the spectral density of such graphs. Finally, I will point out implications of these result on the macroscopic properties of amorphous solids.

JIHT RAS, Moscow, Russiaמארגן המחלקה לפיזיקה של חלקיקים ואסטרופיזיקהצרו קשר תקציר Show full text abstract about Theoretical research in the Joint Institute for High Tempera...» Theoretical research in the Joint Institute for High Temperature of RAS on the intense laser interaction with matter are discussed in view of current and future experiments, in particular with PHELIX at GSI-FAIR, Darmstadt.
A wide-range models elaborated in JIHT RAS are used for the description of material response on the intense laser action. Comparison of experimental findings with the results of simulation is used both for the numerical model verification and for estimations of the interaction parameters that cannot be measured directly in experiments.
Electron acceleration mechanisms are discussed and analysis of the experimental data on X-ray generation at relativistic laser intensities is presented. Generation of energetic electron bunches in the laser interaction with low density targets, and also with preplasma created by laser prepulses at grazing incidence to solid targets are under discussion.
The theoretical support of laser-matter experiments and optimization of secondary sources of high energy particles and photons for warm dens matter diagnostics are considered.

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.
