A study has given new insights into how sleep contributes to brain plasticity – the ability for our brain to change and reorganise itself – and could pave the way for new ways to help people with learning and memory disorders.
Researchers at the Humboldt and Charité Universities in Berlin, led by Dr Julie Seibt from the University of Surrey, used cutting edge techniques to record activity in a particular region of brain cells that is responsible for holding new information – the dendrites.
The study, published in Nature Communications, found that activity in dendrites increases when we sleep, and that this increase is linked to specific brain waves that are seen to be key to how we form memories.
Julie Seibt, et. al. Cortical dendritic activity correlates with spindle-rich oscillations during sleep in rodents. Nature Communications, 2017; 8 (1) DOI: 10.1038/s41467-017-00735-w

Does the paper contain a scatter plot of "cortical dendritic activity" vs "spindle-rich oscillations"?
Fig 1
- no scatterplot
Fig 2
- no scatterplot
Fig3
- "Sigma power density" vs "Dendritic Ca2+ power density"
- "Sigma power density" vs " Layer 2/3 neuron Ca2+ power density"
- "Sigma power density during slow wave sleep" vs "Ca2+ power density during REM sleep"
Fig4
- "change in sigma/beta power density" vs "change in Ca2+ power density"
Fig5
- "normalized fluorescence" vs "sigma power density"
Fig6
- "Dendritic Snychrony" vs "sigma/delta power density"
Fig7
- "spindle density" vs "sigma/beta/SO power"
Apparently sigma (9-16 Hz) and beta (16-60 Hz) are spindle rich frequency ranges, and Ca2+ fluctuations is being defined as "cortical dendritic activity". So ok. I don't see why there isn't a plot of "spindle density" vs "Dendritic Ca2+ power density" though. This seems to be missing even though they clearly collected both types of data.
