Selective attention is central to cognition. Dramatic advances have been made in
understanding the neural circuits that mediate selective attention. Forebrain networks, most …

Spatial attention enables the brain to analyse and evaluate information selectively from a
specific location in space, a capacity essential for any animal to behave adaptively in a …

Karten's neocortex hypothesis holds that many component cell populations of the sauropsid
dorsal ventricular ridge (DVR) are homologous to particular cell populations in layers of …

The cholinergic division of the avian nucleus isthmi, the homolog of the mammalian nucleus
parabigeminalis, is composed of the pars parvocellularis (Ipc) and pars semilunaris (SLu) …

Au cours des dernières décennies, un nombre important de travaux ont été menés sur le
système visuel géniculo-strié des primates. Cependant, les études du système visuel aviaire …

The nucleus isthmi pars magnocellularis (Imc) and pars parvocellularis (Ipc) influence the
receptive field structure of neurons in the optic tectum (TeO). To understand better the …

We provide an extensive review of the pigeon visual system, focussing on the known cell
types, receptive field characteristics, mechanisms of perception/visual attention, and …

We describe the operation of a midbrain neural circuit in pigeons that may participate in
selecting and attending to one visual stimulus from the myriad displayed in their visual …

Reptiles and birds are a fascinating group of animals that is most critical to understanding
the evolution of vertebrate brains. Birds are the only class of vertebrates that can rival …

Fast oscillatory bursts (OBs; 500-600 Hz) are the most prominent response to visual
stimulation in the optic tectum of birds. To investigate the neural mechanisms generating …
