What is the vertebrate brain?
Q: What is the vertebrate brain?
A: The vertebrate brain is the main part of the central nervous system in vertebrates (and most other animals). It is located in the head and protected by the skull, and it processes data from the senses to control other organs of the body.
Q: How much does an adult human brain weigh?
A: An adult human brain typically weighs between 1300-1400 grams.
Q: What role does the spinal cord play in movement?
A: The spinal cord can cause reflex responses as well as simple movements such as swimming or walking. However, more complex behaviour requires a centralized brain.
Q: How do mammals learn?
A: Mammals, particularly humans, are able to develop their brains further through learning during life. This helps them better adapt to their environment.
Q: What structure allows for learning in mammals?
A: Learning capacity is seen best in the cerebral cortex of mammals.
Q: How does behavior differ between lower animals and mammals?
A: In so-called 'lower' animals, most or all of their brain structure is inherited which causes instinctive behavior. In contrast, mammals are able to develop their brains further through learning during life which gives them greater flexibility in behavior.
Q: What evolutionary changes have occurred with regards to vertebrate brains?
A: Throughout evolution, vertebrate brains have become more effective due to changes that have taken place over time.
