Título: "Spatial tuning properties of excitatory 
and inhibitory synaptic inputs onto primate 
retinal ganglion cells� (“Propiedades 
espaciales de los aferentes sinápticos 
excitatorios e inhibitorios en células 
ganglionares de la retina del primate�)

Resumen: In the visual system, inhibition plays 
very diverse and critical roles ranging from the 
control of the critical period for cortical 
plasticity to the generation of direction 
selectivity in the retina. Inner retinal 
inhibition is often thought to shape the temporal 
properties of the light response but not spatial 
tuning. We investigated the contribution of the 
inner retina to spatial tuning of retinal 
ganglion cells (RGCs) by measuring the spatial 
organisation of excitatory and inhibitory inputs 
onto RGCs in the marmoset. Our results show that 
spatial tuning of excitatory inputs onto ON and 
OFF RGCs has similar profiles whilst inhibitory 
inputs are asymmetric. Inner retinal inhibition 
shapes the spatial tuning of excitatory inputs of 
both ON and OFF RGCs and provides direct inhibitory input onto RGCs.
