What was the result of ablation of the cerebral cortex in a pigeon as discovered by Pierre Flourens?

The result of ablation of the cerebral cortex in a pigeon as discovered by Pierre Flourens was a complete loss of perception and voluntary movement. Flourens conducted experiments where he removed portions of the cerebral cortex in various animals, including pigeons, to study the effects of these lesions on behavior and cognitive function.

His findings demonstrated that the cerebral cortex plays a crucial role in the processing of sensory information and in the regulation of voluntary motor activity. With the removal of this area, pigeons exhibited significant deficits in both their ability to perceive their environment and to carry out voluntary movements, highlighting the importance of the cerebral cortex in these functions. This research contributed significantly to the understanding of brain organization and the specific functions of different regions, laying the groundwork for future neurological studies.
