In additional to being able to see the simulation in real-time, I'd also like to have the following:</p> <ul> <li><strong>Network activity</strong>; firings per second; separate for inh and exc neurons? separate for different types of neurons?</li> <li><strong>Neuron connections and delays</strong>; would show incoming/outgoing connections and their delays; spike propagation</li> <li><strong>Neuron activity</strong>; would include the input current (I), the recovery current (u), and the membrane potential (v); would generate something similar to <a href="modeling/neural-modeling-neuron">this digram</a> only in real-time</li> <li><strong>Synaptic weights</strong>; would show current and previous value of all synaptic connections (incoming, outgoing, or both?) of a neuron</li> <li><strong>Neuron properties</strong>; to view/edit properties of individual neurons</li> <li><strong>Neural complexes</strong>; to research <a href="intelligence/symbol-polychronization">polychronous groups</a></li> </ul> <p><a href="http://www.btinternet.com/~cfinnie/">Neural Viewer</a> already provides most of what I need (it also has help, comments, console, and network selection screens), but, unfortunately, the source code for it is not available.</p> <p>To implement this in OpenGL/GLUT in addition to some <a href="http://www.lighthouse3d.com/opengl/glut/index.php?2">basic functions</a> I would need to at least know the following:</p> <ul> <li><a href="http://www.lighthouse3d.com/opengl/glut/index.php?4">Animation</a></li> <li>Use of <a href="http://www.lighthouse3d.com/opengl/glut/index.php?5">keyboard</a> and <a href="http://www.lighthouse3d.com/opengl/glut/index.php?9">mouse</a></li> <li><a href="http://www.lighthouse3d.com/opengl/glut/index.php?8">Working with the camera</a></li> <li><a href="http://www.lighthouse3d.com/opengl/glut/index.php?subwinrender">Rendering to multiple windows</a></li> <li><a href="http://www.lighthouse3d.com/opengl/displaylists/index.php3?1">Display lists</a></li> <li><a href="http://www.lighthouse3d.com/opengl/picking/">Picking objects</a></li> <li><a href="http://www.linuxfocus.org/English/March1998/article28.html">Creating graphs</a> and <a href="http://www.lighthouse3d.com/opengl/glut/index.php?strokefont">working with text</a></li> <li><a href="http://pubs.logicalexpressions.com/Pub0009/LPMArticle.asp?ID=381">Setting timer callback</a></li> <li>and <a href="http://www.amazon.com/exec/obidos/ASIN/0321237625/ref=nosim/soaplite-20">more</a></li> </ul> modeling/ 2006-01-09T00:47:59Z
