Real vs Artificial Neural Behaviour

Posted 29 Aug 2005 at 18:42 UTC by steve Share This

The neurons in an Artificial Neural Network (ANN) are typically simple compared to real biological neurons. Artificial neurons don't require fuel in the form of a blood supply. They don't interact with astrocytes when signalling neighboring neurons. To find out how important these differences might be, researchers Xi Shen and Philippe de Wilde have developed a more realistic neural network simulation that includes neurons, glial cells, capillaries with variable dialation to supply blood, bidirection neuron-glial cell signalling, and astrocyte interactions with neuron excitation. They believe their new model shows some interesting emergent behaviours as well as evidence of an attractor instead of random behavior exhibited by similarly structured neuron-only networks. The details can be found in their paper, Long-term Neuronal Behavior Caused by Two Synaptic Modification Mechanisms (PDF format).

hmm.. I wonder what the equivalent of alcohol is to this neural net?

Bad math, noisy inputs.

I could see someone throwing alcohol on my hot head robot and it goes up in flames then wobbles off down the street like a drunk robot as it melts into a blackened liver-looking bubbling goo!
