Question
In humans, synaptic construction and reconstruction: A) Begins at birth B) Always produces a beneficial outcome for the individual C) Is strongly influenced by experience D) Is most likely complete by age 65 at 42. Chegg Two groups of rats were tested on how fast they could learm to run a maze. Group 1 was given enrichment (handled every day and had toys in the cage), while Group 2 had no enrichment. The result of enrichment on speed of learning the maze was most likely: 43. A) Not effective: both groups learned the maze at the same rate B) Inhibitory: the group with enrichment learned the maze at a slower rate C) Facilitating: the group with enrichment learned the maze at a faster rate D) Dependent on the type of rat studied ly recent 44. In the mature human brain, most changes consist of A) B) C) D) Growth of new neurons Reorganization of connections for existing neurons Neural death Maintaining status quo of the existing neuronsExplanation / Answer
42. The correct answer is Option D. In humans, synaptic construction and reconstruction is most likely complete by 65 years.
43. The correct answer is Option C. The group with enrichment learned the maze at a faster rate.
44. The correct answer is Option B. In the mature human brain, most changes consist of reorganization of connections for existing neurons.
