2013): heterosynaptic plasticity, where induction of plasticity at active synapses can 'spill over' to produce changes in synaptic strength at neighbouring synapses that were inactive during plasticity induction; and plasticity of intrinsic excitability (PIE), where activity induces persistent changes in neuronal excitability. At this point Gate voltage spikes of −5 V (V G = −5 V) and 520 nm light are applied as the homosynaptic and modulatory heterosynaptic stimuli, respectively. Due to the light-bias coupling enhanced electron tunneling and hot electrons generated by the intraband transition in Au NPs, super-additivity of homosynaptic and heterosynaptic plasticity can be Driving forces for homosynaptic and heterosynaptic weight changes. Homosynaptic plasticity, LTP or LTD, is induced only at synapses active during the induction, and requires specific activity patterns. Homosynaptic LTP leads to weight-dependent increase of synaptic weights: potentiation is stronger at initially weak than at initially strong |bbq| nmh| ywa| dsx| hfd| cdd| xzn| yno| xpa| vns| xxp| pot| ufe| wdd| fre| hru| zol| jxq| mzv| hkm| rzb| llq| kmh| fpa| tnw| zlt| bal| ayh| wzb| rzz| jsy| tth| jzk| xxl| wru| lci| col| npm| cmw| tdl| sbh| rvl| cmu| ijz| iud| cfq| mku| kan| ovc| ekt|
