Compared with young rats that have been raised in an "impoverished" environment, young rats that have been raised in an "enriched" environment have:
A) more dendritic branches and more synaptic connections in the cerebral cortex.
B) a much stronger tendency to favor their left paws.
C) an enlarged medulla and reticular formation.
D) about half as many glial cells but almost double the number of neurons in their brain.

Question

Quizplus · Accepted Answer

Studies have shown that rats raised in an enriched environment with opportunities to engage in exploratory behavior, social interaction, and physical exercise have more dendritic branches and synaptic connections in the cerebral cortex compared to rats raised in an impoverished environment. This suggests that environmental stimulation during development can have a significant impact on brain structure and function.

B, C, and D are incorrect as they do not align with the findings of studies on environmental enrichment and brain development in rats.
