• Invariant computations in local cortical networks with balanced excitation and inhibition 

      Mariño Alfonso, Xurxo; Schummers, James; Lyon, David C.; Schwabe, Lars; Beck, Oliver; Wiesing, Peter; Obermayer, Klaus; Sur, Mriganka (Nature, 2005-06-23)
      [Abstract] Cortical computations critically involve local neuronal circuits. The computations are often invariant across a cortical area yet are carried out by networks that can vary widely within an area according to its ...
    • The operating regime of local computations in primary visual cortex 

      Stimberg, Marcel; Wimmer, Klaus; Martin, Robert; Schwabe, Lars; Mariño Alfonso, Xurxo; Schummers, James; Lyon, David C.; Sur, Mriganka; Obermayer, Klaus (Oxford University Press, 2009-02-16)
      [Abstract] In V1, local circuitry depends on the position in the orientation map: close to pinwheel centers, recurrent inputs show variable orientation preferences; within iso-orientation domains, inputs are relatively ...
