“…Nucleus isthmi and the superficial layers of the OT are reported as visual areas in birds and in homologues structures in mammals (Wang, 2003;King, 2004). However, in barn owls, these areas are bimodal (Knudsen, 1982;Maczko et al, 2006).…”

“…It is generally agreed that this feedback can modify the flow of sensory information from the periphery, thus mediating attention and facilitating the extraction of relevant information. Various operations such as selective gating (Sherman, 2001;Le Masson et al, 2002), gain control (Bastian, 1986a), modulation of receptive field (RF) properties (Wang, 2003), and control of bursting firing patterns (Krahe and Gabbiani, 2004) can be mediated by feedback pathways. The precise mechanisms by which feedback mediates these effects are, however, poorly understood.…”

“…The nucleus isthmi is found in all classes of vertebrates (Wang, 2003). In birds, the isthmic complex includes at least three nuclei: pars parvocellularis (Ipc), pars magnocellularis (Imc), and pars semilunaris (SLu) (see Fig.…”

“…Previous research has characterized the Ipc as a visual processor (Wang, 2003). Across a wide range of species, neurons in the nucleus isthmi respond to visual stimuli [teleost fish (Northmore, 1991)] and have spatially restricted visual receptive fields (RFs) that are organized into a topographic map of visual space [cat (Sherk, 1978); frog (Gruberg and Lettvin, 1980;Wang et al, 1981); pigeon (Yan and Wang, 1986;Wang and Frost, 1991); salamander (Wiggers and Roth, 1991)].…”
