Which lobe of the brain is responsible for long term memory?
The temporal lobe consists of edifices that are essential for declarative or long-term memory. Declarative or explicit memory is understanding memory classified into semantic memory (facts) and episodic memory (events). The temporal lobe is important for long-term memory to involve the hippocampus, accompanying the surrounding hippocampal region consisting of the perirhinal, parahippocampal, and the entorhinal neocortical regions. The hippocampus is significant for memory formation, and the encompassing medial temporal cortex is currently theorized to be significant for memory storage. The prefrontal and visual cortices are similarly committed in explicit memory.

How to understand temporal lobe?
In order to fully comprehend the temporal lobe, it is best to analyze it also through its functional connectivity, not just its gross structure. The idea that certain parts of the brain perform certain functions is called localizationism. Localizationism does not always correspond to predictions of functions. Connections define functions. On the other hand, without understanding function, connections of structures are useless. Hence, in order to see the whole picture, structure, connections, and functions must be correlated. [1][2]
What are the three areas of the temporal gyrus?
Temporal area 1 anterior (TE1a), middle (TE1m) and posterior (TE1p) are found in the MTG. All three areas have functional connectivity to different parcellations of the frontal, temporal and parietal lobes. TE1a has additional functional connectivity to some STS areas, temporal gyrus ventral (TGv), entorhinal cortex (EC), and hippocampus. All three areas have white matter connections (structural connectivity) to "u" fibers of the occipitotemporal system and arcuate/SLF. TE1a has an additional white matter connection to inferior longitudinal fasciculus (ILF). These areas are primarily responsible for processing visual information, including working memory for short term visual maintenance of information. [3][5]
