gib65 Posted April 27, 2007 Share Posted April 27, 2007 What makes a neural network programmable (actual neurons, not the computer simulation of them)? I've learnt that neurons don't physically move their dendritic connections from one cell to another (not in the adult brain, at least), so what changes when we talk about a neural network being "programmed"?

gib65 Posted April 30, 2007 Author Share Posted April 30, 2007 Come on. Somebody must have an answer to this one. Link to comment Share on other sites More sharing options...
Genecks Posted May 4, 2007 Share Posted May 4, 2007 I figure it's electron and chemical signaling that changes/alters/is built. I'm not too sure. If one thing is constant, then something else must be moving around. That's the philosophical bit right there: dependent vs. independent. Link to comment Share on other sites More sharing options...
bascule Posted May 4, 2007 Share Posted May 4, 2007 Generally, changes in the connections between neurons Link to comment Share on other sites More sharing options...
Genecks Posted May 4, 2007 Share Posted May 4, 2007 What kind of changes? What connections? Link to comment Share on other sites More sharing options...
gib65 Posted May 4, 2007 Author Share Posted May 4, 2007 Just answer me this question: can an excitatory connection change to an inhibitory one (and visa-versa)? Link to comment Share on other sites More sharing options...

Actually, neuronal plasticity is widely accepted, dendritic spines form and retract according to experience so yes you can "program" your neural networks with experience. Synaptic formation and axonal sprouting is a huge area of research. Neurons are not stationary the will guide themselves to the optimal conditions which can change daily. Neurogenesis and apoptosis occur well into life. Link to comment Share on other sites More sharing options...
