Septal area lesions impair spatial working memory in homing pigeons (Columba livia).

摘要: The septo-hippocampal system in birds resembles that of mammals, motivating research into the function avian hippocampus while surprisingly little attention has been given to septum. To investigate a possible role septum memory, effects septal area lesions on spatial working memory (SpWM) task was tested homing pigeons. After preoperative training an analogue eight-arm (feeders) radial maze, now sham-operated control and lesioned pigeons were then trained again same locating four feeders test phase trial not baited during sample trial. During trial, pigeons, compared both their own performance controls, required significantly more choices locate they made fewer correct responses first choices. results demonstrate that, like its mammalian counterpart, plays important SpWM, suggesting at least some functional properties are evolutionarily conserved mammals.
