One is complex forms of memory, which require the hippocampus and (are called) explicit memory storage.
Sleep-deprived gamers, who still relied on the hippocampus, had to think harder about their virtual navigation.
And in some previous studies where the hippocampus was stimulated, memory was actually disrupted.
Nobody knows what triggers these dramatic morphological changes in the hippocampus during and after hibernation.
Without help from the hippocampus, new semantic memories are too weak to be intentionally recalled.
In taxi drivers, the back of the hippocampus was larger than it was in average men.
Most significantly of all, it shrinks the volume of the prefrontal cortex and the hippocampus.
After four weeks, significant changes were recorded in the hippocampus of the enriched-environment mice compared with controls.
And when we tried to see what comes into the hippocampus, we found it very complicated to analyze.
But it also suggests that the back of the hippocampus is growing at the expense of the front.
The first task was to establish that it was indeed the hippocampus in which changes were taking place.
You've got to see how information comes into the hippocampus and how it is stored over the long term.
Being a romantic, I started out with Alden Spencer to study the hippocampus.
It includes the amygdala, hippocampus, cingulated gyrus, orbital frontal cortex, and the insula.
The researchers do not know why these cells have this defence, but other nearby cells in the hippocampus do not.
Putting the information from each slide together, the researchers were able to devise a mathematical model of a whole hippocampus.
One question: Why would regrowth in the hippocampus reverse depression, when the ailment also affects many other areas of the brain?
The hippocampus is an area at the base of the brain in humans, close to the junction with the spinal cord.
Earlier research showed that the neurons shrink in the hippocampus, and that seems to impair memory in response to stress, he said.
The researchers concentrated on two areas of the brain, the hippocampus and the frontal cortex, areas where plaque formation occurs in humans.
Scientists are already discussing the impact of wiring two hippocampus chips together.
People who learn new vocabulary quickly show more activity in the hippocampus.
ECONOMIST: What makes some people learn language after language?
The researchers recorded a drop in receptor density in the hippocampus - and other key memory centres - of 49% of Alzheimer's patients.
Aging brains rely less on the hippocampus as memory degrades and more on the frontal cortex, which is more focused on reasoning skills.
Slices of rat hippocampus were stimulated with electrical signals millions of times, until scientists could be sure which input produced a corresponding output.
This work shows that sleep trains the brain and promotes memory reorganisation from the hippocampus to the striatum, meaning that navigation becomes more automatic.
Oligomers, which are considered more toxic to brain tissue than amyloid-beta proteins, were applied to the hippocampus, the brain's memory center, in young mice.
The hippocampus, for example, is a part of the brain in the medial temporal lobe, which is very active in spatial navigation and memory.
They concentrate on the hippocampus -- part of the cerebral cortex which sits deep in the brain -- where short-term memories become long-term ones.
These receptors are usually found in particularly high density in the cells of the hippocampus that are most vulnerable to the effects of Alzheimer's disease.
