As the name implies, SyNAPSE involves a bid to redesign chips, code-named Golden Gate, to emulate the ability of neurons to make a great many synaptic connections - a feature that helps the brain solve problems on the fly. (phys.org)
They use an alpha function (up fast, down slow) to simulate a synaptic event. (seeker.com)
There are complex differential equations that must be solved to simulate the ionic flow in the branches, to simulate the ion channels biophysics, the protein-protein interactions, as well as the complete biochemical and genetic machinery as well as the synaptic transmission between neurons.

Differential4
In such simplified models, individual neuron and synapse dynamics are typically described by a small number of coupled differential equations. (frontiersin.org)
In fact you would need a tens of thousands of differential equations to simulate one synapse. (seeker.com)
Synapses are also extremely complex molecular machines that would themselves require thousands of differential equations to simulate just one. (seeker.com)

These molecular pairs operate in a costimulatory fashion, and therefore, single-molecule T-cell studies require to simulate the structure of the IS, where both molecules (pMHC and ICAM-1) are presented simultaneously. (irjs.info)
Simulations2
Suppose that these simulated people are conscious (as they would be if the simulations were sufficiently fine-grained and if a certain quite widely accepted position in the philosophy of mind is correct). (bibliotecapleyades.net)
These are ad hoc simulations employing knowledge from all levels of biology - at the synapse and neurotransmitter level in the brain, but at much higher levels of abstraction for "less important" organs. (dannyreviews.com)
Researchers6
Using electron microscopy, a technique to study brain tissue at ultrahigh resolution, researchers have published detailed 3D-maps of around 25,000 synapses - electrical and chemical signals between brain cells - in the human hippocampus. (theconversation.com)
From a pure energy perspective, the brain is hard to match," says Boahen, whose article surveys how "neuromorphic" researchers in the United States and Europe are using silicon and software to build electronic systems that mimic neurons and synapses. (phys.org)

Now, researchers at Stanford University and Sandia National Laboratories have made an advance that could help computers mimic one piece of the brain's efficient design - an artificial version of the space over which neurons communicate, called a synapse. (stanford.edu)
Like a neural path in a brain being reinforced through learning, the researchers program the artificial synapse by discharging and recharging it repeatedly. (stanford.edu)
