Inspired by the Wikipedia article on the default mode network where I read:

Hans Berger, the inventor of the electroencephalogram, was the first to propose the idea that the brain is constantly busy. In a series of papers published in 1929 he showed that the electrical oscillations detected by his device do not cease even when the subject is at rest.

I came up with the following question:

Are there data available for typical firing patterns of single neurons (of a given type, in a given region or functional unit) in the default mode network in resting state over some significant period of time, say a minute?

By "typical firing pattern" I mean:

  • the overall number of spikes (per minute)

  • the number of isolated spikes

  • the number and duration of tonic bursts

  • the number and duration of other firing patterns as proposed e.g. by Eugene Izhikevich

  • and the mean distances between them

Or are such data not available, maybe because they are too hard to gather or cannot be summarized in a sensible way.

I ask just to get an idea, and because I would like to know if - for example - the maximal, mean, or median number of spikes per minute has an order of magnitude of 10, 100, 1,000 or 10,000 - or even more?

  • $\begingroup$ The DMN is composed of many different cortical brain areas each containing many cell types; I think it would be difficult to define anything as 'typical' among them. There are also no hard borders to the DMN; you could define some for a given purpose, but it would be hard to find agreement. $\endgroup$ – Bryan Krause Jan 14 at 17:35

    $\begingroup$ Both classifying neurons into proper subtypes and recording firing patterns of neurons (in their natural environment) are not very easy tasks. This review (not sure if freely available) is mostly about the classification but also contains a good introduction & some examples on different electro-physiology. $\endgroup$ – Nicolai Jan 17 at 9:41
  • $\begingroup$ @Nicolai, thanks for the link, unfortunately not freely available. (What to do?) $\endgroup$ – Hans-Peter Stricker Jan 17 at 10:41
