Merge Cellular recording

I propose that the newly created stub Cellular recording be merged into (and made a redirect to) here. --Tryptofish (talk) 18:18, 16 June 2011 (UTC)[reply]

Another merge

Having gotten around to the merge above, I realize that we also have Single-cell recording, which should also be merged here. It contains some sourced information on history etc. that should be incorporated in the merge. --Tryptofish (talk) 18:13, 9 September 2011 (UTC)[reply]

Done. --Tryptofish (talk) 21:51, 16 September 2011 (UTC)[reply]

Merge Extracellular field potential

And yet another merge. Extracellular field potential is about exactly the same thing: it's what single-unit recording records. And, unlike local field potential, it's a relatively uncommon term, because for single cells, it's typically just the "extracellular potential". Calling it a "field" is somewhat strange. --Tryptofish (talk) 16:45, 2 November 2017 (UTC)[reply]

Oppose: it seems to me that Extracellular field potential would be better merged to Local field potential as there is no referenced distinction between them. They describe the same type of recording and distinguishing not all authors distinguish between them in the same way. While it is true that single-unit recording are frequently made with extracellular electrodes, they can also be made with intracellular electrodes, as the current article mentions.

Furthermore, the term "extracellular field potential" is also being used to describe potentials close to non-neuronal excitable cells, even in the abscence of nearby axons or terminals; see, for example:

Abi-Gerges, N; Pointon, A; Oldman, KL; Brown, MR; Pilling, MA; Sefton, CE; Garside, H; Pollard, CE (2016). "Assessment of extracellular field potential and Ca²⁺ transient signals for early QT/pro-arrhythmia detection using human induced pluripotent stem cell-derived cardiomyocytes". Journal of pharmacological and toxicological methods. 83: 1–15. doi:10.1016/j.vascn.2016.09.001. PMID 27622857.

Here are some using the 'extracellular field potential' to measure 'field' EPSPs (not distinguishing single units), and where the term is indistinguishable from local field potentials:

That's OK with me. Frankly, this was so long ago that I forgot about it. --Tryptofish (talk) 00:08, 24 January 2019 (UTC)[reply]
