Studies of the infant brain show signs of what scientists call synaptic pruning. What occurs during this process? a. The brain creates additional neural connections by removing parts of the surrounding bone. b. Unused synaptic connections and nerve cells are cleared out to make way for new cells. c. New cells work to “rewrite” old cells and ultimately change their functioning. d. New cells will not develop until the body makes sufficient physical space within the brain.
What is meant by the experimental ablation method of studying the brain? a. The approach in which identical experiments are conducted on numerous animals simultaneously b. The approach in which experiments are conducted on animal species to understand the function of the human brain c. The approach in which the brain is preserved with fixatives such as formaldehyde, sliced thin, and then studied with a microscope Od. The approach in which parts of the brain are systematically destroyed to determine their function
