Talk:K-complex

Figure problem
The figure shows a sleep spindle prior to a K-complex where as the situation as stated in the text is that the K-complex usually precedes a spindle. Some readers might find this confusing. There is a need for someone to cut and paste and rejoin up its two halves to put the K-complex first.--LittleHow (talk) 11:24, 24 May 2009 (UTC)

The fifth and sixth sentences of the section on neurophysiology [“Both K-complex and delta wave activity in stage 2 sleep create slow wave (0.8 Hz) oscillation and delta (1.6-4.0 Hz). However, their topographical distribution is different, and the delta power of K-complexes is higher”] are rather difficult to understand. Bwrs (talk) 04:12, 28 June 2010 (UTC)

Homeostasis of synapses
"The activation thresholds of cortical synapses become raised during wakefulness as they process information, and so need to be adjusted back to preserve their signal-to-noise ratio."

This is backwards, and it contradicts the sentences below. The thresholds are lowered (the synapses are potentiated), meaning more signals fire. — Preceding unsigned comment added by Nimblecymbal (talk • contribs) 21:58, 24 January 2013 (UTC)
