How Does the Hippocampus Function?

The hippocampus of the brain is a region of the brain that helps humans process long-term learning and memory events such as sound, light, and taste, and plays a so-called "declarative memory" function. In medicine, the "hippocampus area" is an inner fold area of the cerebral cortex. It forms an arched bulge around the "choroidal fissure" at the bottom of the "lateral ventricle". It is composed of two fan-shaped parts. Sometimes the two are collectively called the hippocampal structure. .

Study shows damage to brain hippocampus affects imagination

Research by British scientists has found that people with damaged hippocampus regions have poor imagination in addition to poor memory. According to foreign news reports, scientists have previously known that damage to the hippocampus can lead to amnesia, and researchers at the University College London have further explored the impact on other aspects.

Damage to the hippocampus of the brain affects imagination

The damaged hippocampus were asked to imagine a future friend meeting or Christmas party, or imagine being in a beach or bar, but they reported that they could not form a specific image in their brains, and replaced it with a bunch of separated images. Debris. Researchers believe that this may be because the hippocampus is responsible for providing the brain with an environment for constructing various images. ^[3] Researchers have published the results of this research in the Journal of the National Academy of Sciences.

"Creating" memories

In September 2012, according to Discover Magazine, several neuroscientists reported in the online version of Nature and Neuroscience that they implanted artificial memory in slices of rat brain hippocampus. The researchers stimulated rodent brain cells with electrical currents, causing them to produce memory-like nerve cell activities that would last about 10 seconds. This is the first time that researchers have created memory without a brain. Ben Strowbridge, a neuroscientist involved in the study, said at a news conference. "This study paves the way for future research and helps researchers determine which brain circuit is what makes us form short-term memories." ^[4]

Achieving the "Dream of Dreams"

In September 2012, Matt Wilson, a neuroscientist at the Massachusetts Institute of Technology's Pickall Learning and Memory, said his research team is currently exploring how the hippocampus in the brain encodes the events it experiences as memories. In this groundbreaking study, scientists at the Massachusetts Institute of Technology in the United States succeeded in influencing mice's dreams by repeatedly playing the environmental sounds encountered by mice a few days ago. The realization of the human reality version of the stealing dream space is just around the corner ^[5] .
