Illustration of a cortical network. The figure shows a connectivity model with connections from region A to region B. Forward connections (FW) originate from superficial pyramidal cells and target (1) spiny stellates and (2) deep pyramidal cells. Backward connections (BW) originate from deep pyramidal cells and target (1) superficial pyramidal cells and (2) inhibitory interneurons. The arrows represent effective connections. Forward connections are displayed in light blue, backward connections in dark blue.

In this paper, we provide a computational account of changes in synaptic connectivity within two regions of the fronto-parietal network, the dorsolateral prefrontal cortex and the pre-supplementary motor area, applying Dynamic Causal Models to electrocorticogram recordings from two macaque monkeys performing a problem-solving task that engages work...

The primary motor cortex (M1) is known to be spatially organized in terms of muscles and body parts, notwithstanding some overlap. However, the classical view is largely static, neglecting potential representational changes on a fast time scale. To address potential representational dynamics, we probed the mutual information between M1 signals reco...
