Energy Efficient Sparse Connectivity from Imbalanced Synaptic Plasticity Rules
It is believed that energy efficiency is an important constraint in brain evolution. As synaptic transmission dominates energy consumption, energy can be saved by ensuring that only a few synapses are active. It is therefore likely that the formation of sparse codes and sparse connectivity are fundamental objectives of synaptic plasticity. In this work we study how sparse connectivity can resul...

متن کاملEffects of visual deprivation on synaptic plasticity of visual cortex
TBS (Theta Burst Stimulation) and PBs (Primed Bursts) are among effective tetanic stimulations for induction of LTP in hippocampus. Recent studies have indicated that TBS is effective in LTP induction in layer III synapses of neocortex, only if applied to layer IV. However, the possibility of neocortical LTP induction using PBs, has not yet been investigated. Sensory deprivation greatly influ...

متن کاملSynaptic plasticity
Most neurobiologists believe that memories are encoded in the pattern of cortical synaptic strengths, that is, in the effectiveness with which one neuron in the brain communicates with another at each of its synapses. As the human cortex contains about 1014 synapses (100 trillion), a lot of information could be stored. Understanding how memory works is, by general agreement, one of neurobiology...
