Both electric and chemical synapses play an important role in receiving and propagating signals, and thus an isolated neuron and neurons in networks can be activated to trigger appropriate firing modes. The synaptic plasticity enables adaptive regulation in the channel current along the synapse ...
Short-term synaptic plasticity, in particular short-term depression and facilitation, strongly influences neuronal activity in cerebral cortical circuits. ... CM Hempel,KH Hartman,Wang, X.-J.,... - 《Journal of Neurophysiology》 被引量: 342发表: 2000年 The chemical synapse goes electric: Ca2+...
elements exhibiting a current- or voltage-controlled negative differential resistance will separate into coexisting domains with different current densities or electric fields, respectively, in a process similar to spinodal decomposition of a homogeneous liquid or disproportionation of a metastable chemical ...

Through this approach, we found a wake-up effect during the process of crystallization and a transformation from orthorhombic nano-domains to the stripe domain. Furthermore, we have proposed an innovative artificial neural synapse concept based on the continuous polarization variation under applied ...
The KEGG database screening showed that the lead interacts with xenobiotics metabolism (drug metabolism cytochrome P450, score 0.4) and the nervous system (serotonergic synapse, score 0.3). In addition, the Reactome database was identified in G alpha (s) signalling events (0.26) and hormones ...
Thus, the membrane potential shifts from resting potential to action potential, which is mainly determined by the ratio of Na+ concentration inside the cell to that outside the cell at the synapse or at a partial area of the synapse. The change in the membrane potential is immediately ...

These demands have prompted two-terminal memristors as promising candidates for artificial synapses because they can be implemented by silicon-compatible technology with high density and emulate synaptic plasticity with low power consumption6–8. In order to obtain wider support for artificial synapse ...
