Spike to Spike Model and Applications: A biological plausible approach for the motion processing
We propose V1 and MT functional models for biological motion recognition. Our V1 model transforms a video stream into spike trains through local motion detectors. The spike trains are the inputs of a spiking MT network. Each entity in the MT network corresponds to a simplified model of an MT cell. From the spike trains of MT cells a motion map of velocity distribution is built representing a se...

متن کاملSpike timing dependent plasticity: mechanisms, significance, and controversies
Long-term modification of synaptic strength is one of the basic mechanisms of memory formation and activity-dependent refinement of neural circuits. This idea was purposed by Hebb to provide a basis for the formation of a cell assembly. Repetitive correlated activity of pre-synaptic and post-synaptic neurons can induce long-lasting synaptic strength modification, the direction and extent of whi...
متن کاملTo Spike or Not to Spike: That Is the Question
Both the brain and digital computers process information, but they do this in completely different ways. Neurons in the brain transmit information not through bits, but through spikes. Spikes are short voltage increases [see inset in the figure above] that are generated near the cell body of a neuron, with average spike rates below 10 Hz. These spikes are transmitted via fine axonal fibers and ...
متن کاملDynamic Spike Super-resolution and Applications to Ultrafast Ultrasound Imaging
We consider the dynamical super-resolution problem consisting in the recovery of positions and velocities of moving particles from low-frequency static measurements taken over multiple time steps. The standard approach to this issue is a two-step process: first, at each time step some static reconstruction method is applied to locate the positions of the particles with super-resolution and, sec...
