DESCRIPTION:Speaker: Julijana Gjorgjieva\nhosted by Tim Vogels\nAbstract: S
 ynaptic inputs on cortical dendrites are organized with remarkable subcell
 ular precision at the micron level. This organization emerges during early
  postnatal development through patterned spontaneous activity and manifes
 ts both locally where synapses with similar functional properties are clus
 tered\, and globally along the axis from dendrite to soma. Recent experime
 nts reveal species-specific differences in the local and global synaptic 
 organization in mouse\, ferret and macaque visual cortex. I will present a
  computational framework that implements functional and structural plastic
 ity from spontaneous activity patterns to generate these different types 
 of organization across species and scales. Within this framework\, a singl
 e anatomical factor - the size of the visual cortex and the resulting magn
 ification of visual space - can explain the observed differences. This al
 lows us to make predictions about the organization of synapses also in oth
 er species and indicates that the proximal-distal axis of a dendrite might
  be central in endowing a neuron with powerful computational capabilities
 .
