I made some changes (hopefully you will see them as improvements) in the first few paragraphs. I think this is a good start! --Smithfarm 11:26, 12 Apr 2005 (UTC)

I saw it, thanks a lot! Ben (talk) 11:32, Apr 12, 2005 (UTC)

An idea how to rename the section "earlier models", or maybe a more general idea about how to structure the article? Ben (talk) 11:45, Apr 12, 2005 (UTC)

[edit] Another naming issue

Why the use the plural Biological neural networks instead of Biological neural network? Besides being consistent with Artificial neural network, the latter seems to better follow the naming conventions. Wmahan. 03:15, 2005 Apr 13 (UTC)

right, my mistake. I'll rename it. Ben (talk) 05:59, Apr 13, 2005 (UTC)

[edit] next rough sketch

  • I think the structure of the article is now more or less clear. I think the most important parts (and where I plan to work on) will be "connections" and "representations", especially theories of neuronal coding. I also put some new links in the external links section they will give some fast information on some topics. Ben talk contr 11:45, Apr 14, 2005 (UTC)

[edit] history section

The section could use material from articles in the Category:History of neuroscience. Anybody? Ben T/C 06:36, Jun 6, 2005 (UTC)

[edit] Potassium channels?

In the description of the electrochemical mechanisms responsible for precluding the backpropagation of AP's along the axon toward the soma, you neglect to mention the involvement of voltage-gated potassium channels, instead choosing to focus exclusively on sodium. Might you consider mentioning the role of K+ channels in engaging repolarization and undershoot, creating the time-delay that helps prevent backfiring? Or would that be more than this article needs to cover?

I'm not sure of the terminology in neuroscience literature, but the papers I read that focus on the biophysics of neuronal nets use backpropagation to refer to the propagation of an action potential back through the dendritic arbor, which does occur in some areas of the brain and has been observed since the 1950s. See neural backpropagation for details. In the meantime, I will add a clarifying paragraph. SamuelRiv (talk) 00:23, 21 November 2007 (UTC)

[edit] Serious issues with first paragraph

The opening sentence reads terribly. Contrast this:
   "In neuroscience, a neural network is a bit of conceptual juggernaut: the conceptual transition from neuroanatomy, a rigorously descriptive discipline of observed structure, to the designation of the parameters delimiting a 'network' can be problematic." as an opening sentence, with a possible alternative introduction:
   "In neuroscience, a neural network is a population of neurons whose inputs or signalling targets define a recognizable circuit."
Does anyone else agree? AdamSebWolf 00:30, 20 April 2007 (UTC)

[edit] Sound, not electrical impulses

Newer research by the physicists Thomas Heimburg and Andrew Jackson at the University of Copenhagen, the neural impulses are made of sound, not electricity. The elctricity is just a bi-product. Maybe worth to mention in the article. 217.68.114.116 (talk) 15:34, 21 January 2008 (UTC)

No, there's already mention on WP. See soliton model. Also, you have the wrong idea about the importance of electricity in the model - they make no statement of the sort that ion currents are a byproduct. Finally, it has not yet been applied to network models. SamuelRiv (talk) 22:53, 21 January 2008 (UTC)
