Influence of hippocampus on the
relationship between discrimination of the own behavior and symmetry
in pigeons. Andrés García, Santiago Benjumea, Manuel Portavella and Vern Bingman Universidad Nacional de Educación a Distancia, Universidad de Sevilla and Bowling Green State University, Spain and USA In previous works (García and Benjumea, 1999) the relationship between discrimination of the own behavior and symmetry emergency was demonstrated in pigeons. After learning by means of conditional discrimination to choose red after responding to the left and to choose green after responding to the right, the animals responded to the left in presence of red and to the right in presence of green without having been trained explicitly. That is to say, symmetry evidence was obtained (Sidman and Tailby, 1982) in a species different to the human one. What we seek now is to check the performance that would show a group of pigeons injured in the hippocampus in a task of this type. The results indicate that the pigeons with the injured hippocampus didn't demonstrate emergency from the symmetrical relationship to the one trained by means of the procedure of discrimination of the own behavior.
