The study on aqueous reservoir computing (RC) has just come into being. Nevertheless, aqueous RC still faces significant challenges. Recently, with the participation of real biological receptors, aqueous neuromorphic engineering is promising to emulate the intricate human brain more closely due to their synaptic resemblance in electrolytes. In this work, biologically switchable volatility and nonvolatility are first explored for real neurotransmitter glutamate-mediated aqueous RC application, which is based on rational synergy between glutamate oxidase catalytic chemistry and porphyrin-based metal-organic framework/tungsten oxide (PCN-224/WO3) photogate in the newly emerged organic photoelectrochemical transistor. As a proof of concept, the glutamate-mediated RC is then developed and explored for image recognition. These results have of potential for advancing real neurotransmitter-mediated aqueous RC toward in-biology application, which are also envisaged to promote bioinspired algorithm-hardware codesign in future aqueous neuromorphic engineering.

01:26Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

01:19The Role of Ion Channels in Neuronal Computation
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....
