Long-term semantic memories seem to be located primarily in the ________.

A) temporal lobes and frontal lobes
B) prefrontal cortex and the brain stem
C) hippocampus and the thalamus
D) parietal lobes and the prefrontal cortex

Long-term semantic memories, which involve factual knowledge and general information, are primarily located in the temporal lobes and frontal lobes of the brain. The temporal lobes are specifically important for semantic memory retrieval, while the frontal lobes are involved in the organization and integration of this knowledge. The hippocampus and thalamus are more closely associated with the formation and consolidation of episodic memories. Parietal lobes are primarily involved in sensory and spatial processing, and the brain stem plays a role in basic physiological functions such as heart rate and breathing.
