17. The Hippocampus: from Memory into Space and Back

Prof. Alessandro Treves (SISSA)

I will contrast the spatial and memory narratives that have dominated these last few decades of hippocampal research, leading to the somersault caused by the discovery of grid cells. Besides yielding a Nobel prize for Edvard and May-Brit Moser, grid cells have paradoxically refocused attention on the dentate gyrus, as one of two key innovations introduced in the mammalian nervous system...

8. Chaos and correlated avalanches in excitatory neural networks with synaptic plasticity

Alessandro Vezzani (CNR-NANO)

Irregular firing patterns characterized by power-law distribtion in avalanches size are observed to be fundamental dynamical features of neural networks. Here we show how such dynamical regimes naturally emerge in a disordered mean field model of purely excitatory leaky integrate-and-fire neurons with dynamical synapses modeling short-term plasticity. We compute the phase diagram of the...

16. Critical phenomena at a first-order phase transition in a lattice of glow lamps: Experimental findings and analogy to neural activity

Silvia Scarpetta (SA)

26/09/2016, 16:10

Recent work has shown that networks of non-linear electronic oscillators can recapitulate diverse aspects of neural dynamics, such as formation of complex synchronization patterns, offering opportunities to draw parallels between emergence in biological and engineered systems. However, two pervasive properties found across brains and in-vitro neuronal cultures have not been extensively...
