The medial temporal lobe structures are critical for long-term memory, and include the hippocampal formation, perirhinal cortex, parahippocampal, and entorhinal neocortical regions. [ 4 ] : 196 [ 5 ] The hippocampus is critical for memory formation, and the surrounding medial temporal cortex is currently theorized to be critical for memory storage.
Middle temporal gyrus is a gyrus in the brain on the temporal lobe. It is located between the superior temporal gyrus and inferior temporal gyrus. It corresponds largely to Brodmann area 21. The middle temporal gyrus is bounded by: the superior temporal sulcus above; the inferior temporal sulcus below;
Brodmann regarded the location of area 28 adjacent to the hippocampus as imprecisely represented in the illustration of the cortex of the guenon brain in Brodmann-1909. It is located on the medial aspect of the temporal lobe .
The entorhinal cortex (EC) is an area of the brain's allocortex, located in the medial temporal lobe, whose functions include being a widespread network hub for memory, navigation, and the perception of time. [1] The EC is the main interface between the hippocampus and neocortex.
[19]: 49 [20] This ridge can also be seen as an inward fold of the archicortex into the medial temporal lobe. [21] The hippocampus can only be seen in dissections as it is concealed by the parahippocampal gyrus. [21] [19] The hippocampus is located in the three-layered archicortex, one of the three regions of the allocortex. [1] [22]
Area 48 – Retrosubicular area (a small part of the medial surface of the temporal lobe) Area 49 – Parasubicular area in a rodent; Area 52 – Parainsular area (at the junction of the temporal lobe and the insula) (*) Area only found in non-human primates. Some of the original Brodmann areas have been subdivided further, e.g., "23a" and "23b ...
The hippocampal formation is a compound structure in the medial temporal lobe of the brain.It forms a c-shaped bulge on the floor of the temporal horn of the lateral ventricle. [1]
The frontal lobe is located at the front of each cerebral hemisphere and positioned in front of the parietal lobe and above and in front of the temporal lobe.It is separated from the parietal lobe by a space between tissues called the central sulcus, and from the temporal lobe by a deep fold called the lateral sulcus, also called the Sylvian fissure.
