MRI. The hippocampus is best imaged in the coronal plane, angled perpendicular to the long axis of the hippocampal body. The three parts of the hippocampus (head, body and tail) can be identified based on morphology and by using local landmarks 3.
What are hippocampal cysts?
Hippocampal sulcus remnant cysts, also known as hippocampal cavities, are remnants of incomplete involution of the embryonic hippocampal fissure and are an incidental finding.
What does damage to the hippocampus do?
If the hippocampus is damaged by disease or injury, it can influence a person’s memories as well as their ability to form new memories. Hippocampus damage can particularly affect spatial memory, or the ability to remember directions, locations, and orientations.
What does choroid fissure cyst mean?
Choroidal fissure cysts are benign intracranial cysts occurring at the level of choroidal fissure. They are usually asymptomatic and discovered incidentally. They are usually small, quite round and noncompressive3). Magnetic resonance imaging (MRI) signal characteristics are similar to cerebrospinalfluid (CSF).
What is hippocampus brain?
Abstract. Hippocampus is a complex brain structure embedded deep into temporal lobe. It has a major role in learning and memory. It is a plastic and vulnerable structure that gets damaged by a variety of stimuli. Studies have shown that it also gets affected in a variety of neurological and psychiatric disorders.
What does the left hippocampus control?
The hippocampus on the language-dominant side (usually the left side of the brain in most people) has a much more important role in memory than the non-dominant side. This hippocampus functions in verbal or language memory and short-term memory.
What is a hippocampus?
Hippocampus is a complex brain structure embedded deep into temporal lobe. It has a major role in learning and memory. It is a plastic and vulnerable structure that gets damaged by a variety of stimuli. Studies have shown that it also gets affected in a variety of neurological and psychiatric disorders.
What causes atrophy of the hippocampus?
While hippocampal atrophy is a key feature of both hippocampal sclerosis (HS) and Alzheimer’s disease (AD), the pathology underlying this finding differs in these two conditions. In AD, atrophy is due primarily to loss of neurons and neuronal volume as a result of neurofibrillary tangle formation.
How common are choroidal fissure cysts?
Choroidal fissure cysts are rare and often incidentally discovered [1]. There are a few cases reported and they are usually asymptomatic. The relationship between complex partial seizure and temporal fissure cyst is controversial [2].
