Two independent cortical subnetworks control
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!

• 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

Oscillatory 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.
