science brain problem of bird vs human?

Question

a bird needs to coordinate the responses to many stimuli when flying. which area of a bird's brain would be relatively larger than in a human brain?

help please

Answer 1

I don't know that any portion of a bird's brain is relatively larger than a human's except maybe for the rhinoencephalon - which controls smell. The portions of the bird brain needed for flight are:

motor cortex - to coordinate muscles used in flying
visual cortex - to see where it is going
superior colliculus - for birds who have stereoscopic vision, in order to control eye movements
inferior colliculus - for balance and processing
primary and secondary integration centers - for processing the information received from visual cortex and balance senses
cerebellum - to integrate muscle control during flight

I don't know if birds have some special sense where they are sensitive to the earth's magnetic field where this somehow helps guide them during flight. But since humans do not have anything like that, there wouldn't even be a portion of the human brain that you can compare it to.

Answer 2

physically a bird's brain cannot be larger than a human brain... its just not a physical possiblity. However - I believe you ment which areas have higer levels of activity... so my guess would be the centers that have to do with maps, direction, flight paths. I believe they have an excellent sence of orientation and its not all instinct as many people believe. Not sure what areas of the brain that would be in tho. sorry.

Answer 3

cerebellum? This part of the brain is used to coordinate movements (motor functions) in the body, and to predict the future (e.g., "Is that rock that somebody threw, going to hit me or miss me if I don't change course?" or "I'm flying and I see a delicious mosquito flying; what course should I take and how fast, to snap it up in my beak in mid-air?"
