Hippocampus

The renaming of the hippocampus as hippocampus major, and the calcar avis as hippocampus minor, has been attributed to Félix Vicq-d'Azyr systematising nomenclature of parts of the brain in 1786.

The researchers were focusing on brain activity in the ventral hippocampus (the underside of the hippocampus).

Jung et al., 1994 The intermediate hippocampus has overlapping characteristics with both the ventral and dorsal hippocampus.

There is evidence that food-caching birds have a larger hippocampus than other types of birds and that damage to the hippocampus causes impairments in spatial memory.

Whether having a bigger hippocampus helps an individual to become a better cab driver, or if finding shortcuts for a living makes an individual's hippocampus grow is yet to be elucidated.

The brain scans also showed that his hippocampus – a part of the brain involved in memory – had shrunk.

The hippocampus, Ranganath explained, is a part of our brain that is good at holding on to the “when” and “where” of memories.

Thus, when you get a smell or a taste that instantly transports you back to an earlier time in your life, that is because your hippocampus, your little seahorse has been stimulated to work.

Under the classical view of systems consolidation, over time, all memories are known to move from their initial storage location of the hippocampus to the neocortex.

When you recall past experiences, such as how much you spent last year during the holidays or remember that the credit card bill is coming soon, you activate your hippocampus.

Blackouts occur when a person consumes enough alcohol that it temporarily blocks the transfer of short-term to long-term memory storage in the brain region named the hippocampus.

Hypertension makes it even more difficult, which may be a reason the hippocampus is one of the first areas affected in Alzheimer’s disease, researchers said.

Researchers trained rats to run back and forth on a raised track with a reward at either end and observed how neurons in their hippocampus “spiked” in the process.

Some people have a greater ability to remember, precisely because i of the hippocampus and frontal cortex, as well as neurotransmitter levels, during REM sleep are slightly different from individual to individual.

The nanoparticles are designed to bind to CD44, a cell surface protein that is produced by reactive astrocytes and microglia cells, more than neurons, especially during neuroinflammation, a hallmark of AD-afflicted brain regions such as the hippocampus.

As part of their pre-surgical preparation, these patients had electrodes placed in the hippocampus and another area of the brain involved in navigation, memory and time perception.

For memories to stick well, there needs to be strong during encoding, which activates the hippocampus.

In Parkinson’s disease, the hippocampus and thalamus are known to be associated with thinking and memory, and the putamen with movement scores, so the researchers say it’s very promising that iron deposition was specifically detected in those areas.

The hippocampus forms connections, even if we don’t want it to,” Burman said.

The maintenance of established remote contextual fear memory requires ERK5 MAP kinase and ongoing adult neurogenesis in the hippocampus:e50455.
