What makes a neural network programmable?

[gib65]

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]

Come on. Somebody must have an answer to this one.

[Genecks]

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.

Generally, changes in the connections between neurons

[Genecks]

What kind of changes? What connections?

[gib65]

Just answer me this question: can an excitatory connection change to an inhibitory one (and visa-versa)?

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.

Thanks armygas,

 

Now I don't mean to doubt you, but would you so happen to have some sources to back this up?

Any basic neuroscience textbook will have this information
