Das Gehirn als Netzwerk: Wiring the brain

Aus der Meldung der University of Cambridge:

“However, we found that cost control alone was not enough to reproduce a wide range of network properties. To do that, we had to model an economical trade-off between cost control and another term which favoured new, direct connections between regions that shared similar input or were otherwise already indirectly linked.” [...]

Dr Petra Vertes, one of the authors of the paper, said: “Our model hints at possible mechanisms behind schizophrenia, which will be interesting to investigate further.  We have been able to model the disease by tuning the parameters to allow a greater probability of connection between distant brain regions.  This result echoes some prior neuroimaging results which suggest that brain networks in schizophrenia may be associated with an abnormal trade-off between connection costs and other topological properties of brain networks.”
