Split-brain patients have had surgery to cut the corpus callosum. Such a phenomenon was studied and monitored by two neuroscientists Roger Sperry and Michael Gazzaniga. After hard operation, patients felt quite good although the expectations weren't that good. Patients could perform all the activities they did before surgery, that was very surprising and innovational. But after several experiments, doctors discovered side effects and got back to study this process.
Answer:
Explanation:
Active - the process of exposing the body to an antigen. Exposing the body will generate an adaptive response that takes a few days or weeks to develop and can be life long lasting.
Passive - it is provided when we are given antibodies to disease. Instead of producing the antibodies with the immune system, they are given. Like a newborn baby acquires immunity from the placenta.
Natural - it works to fight off pathogens before they begin an active infection. Sometimes it is not enough to stop the pathogen or the pathogen exploits the immune response and gets to the cells.
