What Is a Gastrovascular Cavity?
The gastrovascular cavity is a structure found in primitive animal phyla. It is responsible for both the digestion of food and the transport of nutrients throughout the body. The cavity has only one opening to the environment. Food goes in and waste comes out that same opening, making it a two-way digestive tract.
By contrast, organisms that have a mouth on one end with an anus on the other end have a one-way digestive tract, called an alimentary canal. Food goes in the mouth, while waste comes out the anus.
Answer:
Sperry is best known for split-brain research, in which he tested these patients after they had the surgery. Initially he discovered that there are two modes of thinking, verbal and nonverbal. Verbal thought is represented in the left hemisphere while nonverbal thought is represented in the right hemisphere. Once he learned this, he did more research to find out if each hemisphere of the brain could operate on its own.The split-brain experiments that Sperry conducted helped researchers to develop a map of the brain. This laid the groundwork for an entire field of research studying how the human brain functions. As a result, in 1981, he won the Nobel Prize in Medicine.
