The uncinate fasciculus is a hook-shaped bundle of axons that links anterior portions of the temporal lobe with the inferior frontal gyrus and the lower surfaces of the frontal lobe. It arises in the anterior temporal lobe and amygdala, in the temporal lobe curving in an upward pathway behind the external capsule inward of the insular cortex ...
The temporal lobe is located beneath the lateral fissure on both cerebral hemispheres of the mammalian brain. [3] The temporal lobe is involved in processing sensory input into derived meanings for the appropriate retention of visual memory, language comprehension, and emotion association. [4]: 21 Temporal refers to the head's temples.
The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse') is a major component of the brain of humans and other vertebrates.The hippocampus is part of the limbic system, and plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation.
The temporal lobe is involved in processing sensory input into derived meanings for the appropriate retention of visual memories, language comprehension, and emotion association. [10]: 21 Within the temporal lobe is an area of the brain called the hippocampus which is associated with forming new memories and learning new things. The hippocampus ...
The superior longitudinal fasciculus (SLF) is an association tract in the brain that is composed of three separate components. [1] [2] It is present in both hemispheres and can be found lateral to the centrum semiovale and connects the frontal, occipital, parietal, and temporal lobes. [2]
The uncus is an anterior extremity of the parahippocampal gyrus.It is separated from the apex of the temporal lobe by a sulcus called the rhinal sulcus. [1] Although superficially continuous with the hippocampal gyrus, the uncus forms morphologically a part of the rhinencephalon.
The anterior part of the gyrus includes the perirhinal and entorhinal cortices [citation needed]. The term parahippocampal cortex is used to refer to an area that encompasses both the posterior parahippocampal gyrus and the medial portion of the fusiform gyrus [ citation needed ] .
The symptoms of conduction aphasia suggest that the connection between the posterior temporal cortex and frontal cortex plays a vital role in short-term memory of words and speech sounds that are new or have just been heard. The arcuate fasciculus is the main connection between these two regions.
