spike timing of layer 5 pyramidal neurons during
dynamic ß oscillation shiftsKarlijn van Aerde
et al, VU University Amsterdam
Fast network oscillations (beta range) are
dynamic!
- in rat brain slices
- in awake rats
- in human EEG
What is the underlying network? Or should I say
networks!

21- What is the role of primary and secondary sensory
- regions in working memory?
- Which oscillations are involved?
- MEG, median nerve stimulation, delayed-match-to-sa
mple task

22Oscillatory brain activity during human
somatosensory working memory maintenance
- Main conclusions
- Sustained gamma band activity reflects working
memory maintenance first in SI and then
bilaterally in SII. - Alpha band activity reflects functional
inhibition of task-irrelevant regions.
