... of the avian brain. The expansion of this continuum may be relevant to the enlargement of the telencephalon in some species, such as corvids, that are known for their complex behavior. Pigeons are social animals. They often communicate with each other by exhibiting distinct behaviors...

...W. Hodos; H.J. Karten Pigeons were trained to discriminate stimuli that differed in luminance or geometric pattern. Following discrimination training, bilateral stereotaxic lesions were made in the optic tectum and in the associated nuclei isthmi, located within the depth of optic lobe. In some...

.... Pigeons with dorsomedial forebrain lesions, however, failed to return to their respective home lofts. The results show that (1) the avian dorsomedial forebrain plays a critical role in that step of the homing process by which a pigeon returns to its home loft once in its vicinity, and that (2) the failure...

...Anton Reiner; Harvey J. Karten The projection targets of the olfactory bulb in pigeons and turtles were investigated using autoradiographic techniques. Despite the relatively smaller size of the olfactory bulbs in pigeons, the projection targets of the olfactory bulb are very similar to those...
