Examples
This study tracked cells in the hippocampus, a curved structure near the center of the brain in both species that’s vital for learning and memory.
Hassabis, for example, was studying the hippocampus, which processes memory, when he and Legg met.
In previous “replay” algorithms, these data are then transferred to the hippocampus, which stores the memory and uses it for playback.
Previous studies have found that by snipping off the ventral connections from the hippocampus to different brain areas, it’s possible to reduce the impact of memories that normally trigger anxiety.
You see, the hippocampus is special in that it’s one of two brain regions that gives birth to new neurons throughout most of life, although the rate declines with age.
Cortisol is bad for your brain, particularly the hippocampus, which encodes memories.
In depressed people, for instance, the hippocampus tends to be smaller than in healthy people.
Until now, most research on the brain changes caused by stress has focused on the hippocampus, which processes memories.
Eventually it ends in the substance of the hippocampus and in the uncus of the temporal lobe.
The hippocampus, which is otherwise known as the “sea-horse,” affords another interesting example of aquatic locomotion.
The little seahorse (Syngnathus hippocampus) is commonly found here.
The first on the right has two figures of Nereids traversing the sea, one on a sea-bull the other on a hippocampus.
These little cuirassed fishes consist of two genera, Syngnathus and Hippocampus.
