We introduce an internal time-limited charge-based memory into a III\u2013V nanowire (NW) based optoelectronic neural node circuit designed for handling optical signals in a neural network. The new circuit can receive inhibiting and exciting light signals, store them, perform a non-linear evaluation, and emit a light signal. Using experimental values from the performance of individual III\u2013V NWs we create a realistic computational model of the complete artificial neural node circuit. We then create a flexible neural network simulation that uses these circuits as neuronal nodes and light for communication between the nodes. This model can simulate combinations of nodes with different hardware derived memory properties and variable interconnects. Using the full model, we simulate the hardware implementation for two types of neural networks. First, we show that intentional variations in the memory decay time of the nodes can significantly improve the performance of a reservoir network. Second, we simulate the implementation in an anatomically constrained functioning model of the central complex network of the insect brain and find that it resolves an important functionality of the network even with significant variations in the node performance. Our work demonstrates the advantages of an internal memory in a concrete, nanophotonic neural node. The use of variable memory time constants in neural nodes is a general hardware derived feature and could be used in a broad range of implementations.<\/jats:p>","DOI":"10.1088\/2634-4386\/acf684","type":"journal-article","created":{"date-parts":[[2023,9,4]],"date-time":"2023-09-04T22:28:08Z","timestamp":1693866488000},"page":"034011","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Artificial nanophotonic neuron with internal memory for biologically inspired and reservoir network computing"],"prefix":"10.1088","volume":"3","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5191-9728","authenticated-orcid":true,"given":"David","family":"Winge","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8061-0746","authenticated-orcid":true,"given":"Magnus","family":"Borgstr\u00f6m","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5432-3479","authenticated-orcid":true,"given":"Erik","family":"Lind","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9761-0440","authenticated-orcid":true,"given":"Anders","family":"Mikkelsen","sequence":"additional","affiliation":[]}],"member":"266","published-online":{"date-parts":[[2023,9,18]]},"reference":[{"key":"nceacf684bib1","doi-asserted-by":"publisher","first-page":"1007","DOI":"10.1126\/science.aaa5542","article-title":"Engram cells retain memory under retrograde Amnesia","volume":"348","author":"Ryan","year":"2015","journal-title":"Science"},{"key":"nceacf684bib2","doi-asserted-by":"publisher","first-page":"49","DOI":"10.1038\/s42256-018-0001-4","article-title":"Long short-term memory networks in memristor crossbar arrays","volume":"1","author":"Li","year":"2019","journal-title":"Nat.
