Hippocampus looks like a Seahorse and Hippo means Horse in greek and Kampus means sea monster. A Hippocampus is an S-shaped brain structure embedded deep in the temporal lobe of each cerebral cortex. It is an important part of the limbic system, a cortical region that regulates motivation, emotion, learning, navigation, and memory.

The Hippocampus is a structure made of 3 layers of a single pyramidal layer with a plexiform layer on both sides.
A pyramidal is a pyramid-shaped cell or neuron that is found in parts of the brain. It is pretty much a pathway of neurons throughout the brain and it can transmit signals that function to control voluntary movements.
A plexiform layer is made of pyramidal cell axons and hippocampal afferent fibers and contains the Alvear pathway. The plexiform layer is situated near the inferior horn of the lateral ventricle.

The Hippocampus is located deep in the temporal lobe which is in the middle and beside the ear.

The main role of the Hippocampus is memory. It is principally thought that the Hippocampus is involved with storing long-term memory and preserving those memories. The Hippocampus is also thought to be involved with navigation and spatial processing. Think about what you did yesterday? Your hippocampus is working right now trying to figure out what your memory and details of it and there will be some forgotten things. The Hippocampus will try to make it to a cohesive memory and it can help humans find 2 types of memory... Declaritive and spatial relationships. Declarative memories are those related to facts and events. Examples include learning how to memorize speeches or lines in a play.
Spatial relationship memories involve pathways or routes. For example, when a cab driver learns a route through a city, they use spatial memory. Spatial relationship memories appear to be stored in the right hippocampus. The hippocampus is also where short-term memories are turned into long-term memories. These are then stored elsewhere in the brain.

In 1953 a 27-year-old male named Henry Molaison AKA HM suffered from seizures so the doctors removed his temporal lobes without knowing the consequences of what they have done.  HM wasn't capable of forming new memories but had memories of his childhood specifically HIS own memories which are called episodic memories. This operation was a tragedy but at the same time, a really important discovery as surgery on the hippocampi will never be approved again. HM then became an experiment subject in Penfield and Milner's experiments and research about memory. HM passed away on December 2nd, 2008 at the age of 82 but the knowledge that he gave the researchers and students and the world at that a great understanding about memory.

What happens if the Hippocampus gets damaged or affected in any way

Some memory disorders that could appear from damage in the Hippocampus are Short term memory loss, Amnesia, dementia, etc. If you have damaged your Hippocampus it could be that you cannot create new memories or have trouble reciting old memories or recent past events. It could also mean that you have no memory of your past.
