This non-empirical article by Nelson is an argument to provide probability that a person’s environment guides in the development of the brain. The author writes about how the interaction of the brain and environmental experience help in the redesigning process we call neural plasticity. Providing three established procedures to show that our experiences are connected to changes within the brain. These three procedures are: anatomical‚ neurochemical‚ metabolic‚ which may be expressed at any time within

isolated from the teratocarcinomareplicated and grew in cell culture as a stem cell and are now known as embryonic carcinoma (EC) cells. Although similarities in morphology and differentiating potential (pluripotency) led to the use of EC cells as the in vitro model for early mouse development‚ EC cells harbor genetic mutations and often abnormal karyotypes that accumulated during the development of the teratocarcinoma. These genetic aberrations further emphasized the need to be able to culture pluripotent cells

Many animals have been cloned in the past‚ and science is eager to move onto bigger and better things. However‚ the next step in cloning is one of great debate and controversy; human cloning. The biggest obstacle in cloning research is the ethical concern for human life and well-being‚ one that has caused human cloning to be banned in countless
