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]

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]

The general organization of the frontal lobe independent of side includes the formation of gyri (the gray and white matter convolutions of the brain) and sulci (the natural planes in the plane containing the blood vessels). The surfaces of the frontal lobe include the orbital (basal) surface, the lateral surface, and the mesial surface (see diagrams). Within the deep white matter of the frontal lobe is the anterior part of the lateral ventricle which contains cerebrospinal fluid. The posterior part of each frontal lobe known as the precentral gyrus contains the primary motor cortex. Here motor function is arranged according to the part of the body moved (somatotopic representation). The arrangement of cortex is known as the homunculus (see diagram).

Which lobe of the brain is responsible for the formation of language?
Located at the front and middle of the left temporal lobe, respectively, Broca's area and Wenicke's area are the regions of the human brain that handle the formation and processing of language. Regardless of what language you're using, these two regions allow you to form sentences, understand the meaning of what others are saying and pick up on verbal patterns. These regions are the reason why a left temporal lobe hemorrhage can leave a person unable to understand what someone is saying, or lead them to babble incoherently.
