Final answer:
The brain pulls from working memory when looking at one piece of information, which is located in the prefrontal lobe and is used for actively processing and managing information we are currently aware of.
Step-by-step explanation:
When looking at one piece of information, our brain pulls from working memory, also known as active or short-term memory. This type of memory is localized to the prefrontal lobe. According to the Atkinson-Shiffrin model of memory, information must go through three distinct stages: Sensory Memory, Short-Term Memory (working memory), and finally Long-Term Memory, for it to be stored permanently. The function of the hippocampus and medial temporal structures, as suggested by the study of patient HM, is to consolidate short-term memories into long-term memory, which is stored in the temporal lobe. However, working memory is immediately accessible and is the information we are currently aware of or thinking about.
