Two independent cortical subnetworks control spike timing of layer 5 pyramidal neurons during dynamic β oscillation shifts Karlijn 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!

Oscillatory brain activity during human somatosensory working memory maintenance What is the role of primary and secondary sensory regions in working memory? Which oscillations are involved? MEG, median nerve stimulation, delayed-match-to-sample task: SII SI Primary somatosensory cortex (SI)
22
Saskia Haegens F.C. Donders Centre for Cognitive Neuroimaging October 14, 2015 Oscillatory brain activity during human somatosensory working memory maintenance alpha ↑ alpha ↓ gamma ↑ 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.
