What functions are associated with the hippocampus?
The hippocampus is thought to be principally involved in storing long-term memories and in making those memories resistant to forgetting, though this is a matter of debate. It is also thought to play an important role in spatial processing and navigation.
How does the hippocampus affect behavior?
The ability to learn new information about a person, or ourselves, that is tied to a specific event or experience is a characteristic feature of hippocampal-dependent memory, and contributes to our ability to form relationships with others, influences our behaviors towards others, and affects our judgments and …
What is the difference between damage to the left versus the right hippocampus?
Right hippocampus plays a critical role in spatial memory in older adults, while the role of left hippocampus in verbal memory is more prominent.
Why is the fornix important?
The fornix is an important part of the limbic system, and represents the largest single pathway of the hippocampus, connecting it to various subcortical structures. Being a part of the limbic system, the fornix is associated with the processes of cognition, memory consolidation, emotions and sexual responses.
What is the function of the fornix in the female reproductive system?
The fornices of the vagina (sing. fornix of the vagina or fornix vaginae) are the superior portions of the vagina, extending into the recesses created by the vaginal portion of cervix. The word “fornix” is Latin for “arch”….

What happens when hippocampus shrinks?
Hippocampus Shrinkage and Depression Hippocampal shrinkage also damages cognitive functions and interferes with the process of creating memories, which has a profound impact on both behavior and the ability to form a stable, realistic, and cohesive sense of self.
Which type of memory is most impaired by damage to the hippocampus?
In all five experiments, patients with hippocampal damage exhibited impaired recognition memory.
What causes hippocampal atrophy?
The hippocampus and surrounding areas within the medial temporal lobe are typically involved in Alzheimer disease (AD),2–6 but are also affected in other dementias, such as vascular dementia (VaD). In AD, hippocampal atrophy (HA) is usually attributed to the deposition of neurofibrillary tangles and neuritic plaques.
Where does the fornix terminate?
The fibers that constitute the postcommissural fornix arise mainly from the subiculum of the hippocampal formation. The majority of the fibers in the postcommissural fornix terminate in the mammillary body and thalamus.
