Using a twin preterm fetal sheep model, Back and colleagues studied the impact of both hypoxia alone, as well as in combination with ischemia (insufficient blood flow) on the developing hippocampus.
The hippocampus is so named because it resembles a seahorse--the Greek word for horse is hippos and kampus means "sea monster." You actually have two hippocampi, one in the left hemisphere and one in the right hemisphere of the brain.
Inside our brains, a cashew-shaped structure called the hippocampus stores the sensory and emotional information that makes up memories, whether they be positive or negative ones.
In order for the hippocampus to operate normally, there is a fine balance between excitation mediated by the neurotransmitter glutamate, and inhibition mediated by the neurotransmitter GABA.
Each hippocampus (it actually looks not so much like a seahorse, more like a tapering sausage) acts together with adjacent cortical areas to drive the consolidation of experiences into memory traces.
More recent research suggests that the hippocampus also may play a role in social interaction.
Alterations in cortical regions involved in emotion, memory, perception, and salience functions among tinnitus patients have been reported previously.[7],[8] As an important component of the emotion and memory networks, the hippocampus is essential for emotional reaction, learning, and memory.[9],[10] Hippocampus could constantly update the tinnitus signal that is generated in the thalamocortical system preventing habituation.[11] The CA1 area of the hippocampus is of significant importance for neurotransmission in and out of hippocampus, and the possibility of a role for this area in tinnitus is intriguing.
'We know that calcifications in the hippocampus are common, especially with increasing age,' de Brouwer said.
Using autopsied brain samples from 28 people who died suddenly between the ages of 14-79, researchers looked at "newly formed neurons and the state of blood vessels within the entire human hippocampus soon after death," said the Cell Stem Cell study.
Researchers at the Brain Research Institute of the University of Zurich showed for the first time the process by which neural stem cells divide and newborn neurons integrate in the adult mouse hippocampus.
The hippocampus has been one major focus in studying the stress responsivity and neural mechanisms underlying depression.
While playing 3D-platform video games has previously been shown to promote grey matter in the hippocampus in younger adults, in the current study, the researchers tested the impact of 3D-platform video game playing, like Super Mario 64, on grey matter in the hippocampus, cerebellum, and the dorsolateral prefrontal cortex (DLPFC) of older adults.
