Document Summary

Brains are pretty large; forebrain is enlarged. Hindbrain (medulla)- links spinal cord & peripheral nervous system to control regions in brain. Forebrain & midbrain more developed in birds & mammals. Serves similar function as mammalian cerebral cortex. Best developed in crows, parrots & passerines. Right cerebral hemisphere- monitors & filters environmental stimuli. Left cerebral hemisphere- complex integration & learning. The medulla oblongata- automatic (cid:364)housekeeping(cid:365) tasks (breathing and keeping blood warm) Hypophysis- pituitary gland ((cid:364)master gland(cid:365), regulates stress, growth, reproduction. Cortical areas are arranged in columns, like mammals. Cerebellum- balance & coordination during flight (large size) Large eyes and large optic lobes- brain is displaced back and vertically. Birds have very large lens and they tend to be rounder. Can be drawn across the eye for protection and to moisten the eye while maintaining vision. Can see very well straight in front of them.
