SUBICULUM Meaning and
Definition
-
Subiculum is a term primarily used in the field of neuroscience to refer to a specific region of the brain. It is a region found within the hippocampus, which is a crucial part of the brain involved in memory formation and spatial navigation. More specifically, the subiculum is a transitional area situated between the hippocampus proper and the entorhinal cortex.
In terms of its anatomical properties, the subiculum is relatively large and consists of several layers of cells. It is primarily composed of pyramidal neurons and exhibits a distinct structure characterized by dense connections with other regions of the brain, including both incoming and outgoing connections. These connections allow the subiculum to play a critical role in the flow of information within the hippocampal circuitry.
Functionally, the subiculum has been implicated in various important processes. It is involved in consolidation of memories, particularly in transferring information from the hippocampus to other regions of the brain for long-term storage. Additionally, the subiculum has been associated with spatial navigation, decision-making, and regulation of emotional responses. Dysfunction or damage to the subiculum has been linked to memory impairments, epilepsy, and psychiatric disorders such as schizophrenia.
In summary, the subiculum is a distinct region within the hippocampus of the brain that plays a crucial role in memory formation, spatial navigation, and emotional regulation. Its connections with other brain regions and anatomical features make it an essential component of the broader hippocampal circuitry.

Etymology of SUBICULUM
The word subiculum originates from Latin. Its etymology can be traced back to the Latin verb subicere, which means to place under or to support. Subiculum itself is derived from the diminutive form of subicere, which is subiculum. In English, the word subiculum refers to a substructure or a supporting part. In anatomy, the term specifically denotes a curved structure in the brain, namely the hippocampal subiculum.
