Figure problem[edit]

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)[reply]

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)[reply]

Homeostasis of synapses[edit]

"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)[reply]
