Memory Formation In The Hippocampus
My response to Essay B will cover the main areas of the process of and the explanation of memory formation in the hippocampus. The essay will include the long-term potentiation, the hippocampal areas and the overall involvement of the glutamate receptors. I will cover the definitions of what these various areas are and tell about the process itself for how everything flows together.
To start with, the hippocampus itself is essentially like a central hub in the brain that helps us process several different types of actions if you will. These actions are where emotions, memories and the autonomic nervous system all process out of. The hippocampus is basically a one stop shop to generate memories and then also briefly store them as well. This …show more content…
part of the brain is vital to the formation of memories and facts that we process on a routine basis. The hippocampus acts as an entryway as mentioned previously.
The memories are stored in the hippocampus temporarily right after forming and then they move to their permanent location elsewhere in the brain.
The next topic I will cover is the description of memory formation in the hippocampus.
The hippocampal formation is in the temporal lobe. It is small part of the limbic cortex. The formation is a forebrain structure. It is comprised of the hippocampus proper, denate gyrus and the subiculum. From our reading, I learned that the entorhinal cortex is responsible for the primary input to the hippocampal formation. This formation is very precise. We learned in our reading that regardless of how or where you look in the formation, there is the same set of circuits. The long-term potentiation deals with the resulting actions that happen from a surge in the excitability of a neuron. A long-term potentiation is not limited to the hippocampus.
Although it does happen throughout various regions of the hippocampus, it can actually happen in many different parts all throughout the brain. Interestingly enough, the long-term potentiation can actually be something that carries on for several months, hence the name long-term potentiation. It is a process that is very …show more content…
complex.
There is a few different types of long-term potentiation as well. These different types include associative long-term potentiation which is basically the parallel stimulation of weak and strong synapse to a given neuron reinforces the weak ones.
Our brain is comprised of so many different areas. One of those areas is the hippocampus. To break it down even further, there are different areas within the hippocampus as well. The hippocampus is a very complex, three dimensional shape. As mentioned previously, the different areas are the hippocampus proper, the denate gyrus and the subiculum.
This breaks down even further. There are several more areas within the hippocampal formation and they include the following: Fimbria, To septum mammillary bodies, Schaffer commissural axon, Field
CA1, Field CA3, Schaffer collateral axon, Mossy fiber, Field CA1, Axon in performant path,
Dentate gyrus, Record from denate Gyrus, Stimulate axons in performant path, Subicular complex and the Entorhinal cortex. All of these individual areas serve a very important function
with the overall goal of processing memory and emotions and providing temporary storage of memories and emotions before they move to their final destination.
Glutamate receptors play an important role in the process of memory formation in the hippocampus. There are 4 different types of glutamate receptors that are researched and talked about. The majority of the receptors are ionotropic and have been named after the artificial ligands that are responsible for their stimulation. These different receptors are titled: the NMDA receptor, the AMPA receptor and lastly the kainate receptor. The last receptor is based off of a metabotropic and is titled the metabotropic glutamate receptor. These receptors all work
together to play the important role in learning and memory.
Each of the different sections written about in this essay play an important part when it comes to the overall formation of memories in the hippocampus.
