Quotes About Hippocampus

Theodore Berger, for example, a neural engineer at the University of Southern California, is working on an artificial hippocampus, one of the core neuronal structures implicated in this process. Berger's device records the electrical activity that arises whenever we encode short-term memories — for example, learning to play scales — then translates them into digital signals.

The amygdala plays an important role in the acquisition, storage, expression, and extinction of threat memories. The ventromedial prefrontal cortex (PFCVM) regulates the acquisition, storage, expression, and extinction of threat memories by the amygdala. The hippocampus learns about the context of acquisition and modulates the expression and extinction of threat memories in relation to context.

UFCNo such thing as childhood memories, he says. We're just playing games with our neurons every day, tossing them around the hippocampus, constructing little fairy tales featuring characters named after people we used to live with. 'Your dad is just a flurry of molecular activity in your frontal lobe' he'll tell you...

Indeed, brain scans done by scientists at Washington University in St. Louis indicate that areas used to recall memories are the same as those involved in simulating the future. In particular, the link between the dorsolateral prefrontal cortex and the hippocampus lights up when a person is engaged in planning for the future and remembering the past.

It turns out that this part of the brain is one of the first areas that's attacked by Alzheimer's disease. So we can now use some of the basic understanding of this part of the brain to ask the simple question, 'What is going wrong with these special cells in the hippocampus at the very earliest stages?'

The hippocampus helps record both types of memories initially, and it helps retain them for the medium term. The hippocampus also helps us access old personal memories in long-term storage in other parts of the brain.

Throughout our lifetimes, we are constantly regenerating new brain cells in the hippocampus, a process called neurogenesis. New stem cells are constantly being born in the hippocampus that ultimately differentiate into fully functional neurons.

The hippocampus is crucial in recognizing a face as that of your cousin. But it is the amygdala that adds you don't really like her.

Neurobiological research has shown that in people with chronic PTSD, both stress hormone secretion and areas of the brain connected to memory function, such as the hippocampus, appear to be affected, although exactly how and why remains controversial.

There are neurons in the old part of our brain that are known to learn maps of the places we have visited, and these neurons have been under evolutionary pressure for so long that they are fine-tuned to do what they do. In mammals, the old brain parts where these map-creating neurons exist are called the hippocampus and the entorhinal cortex.

In 2005, scientists in the lab of May-Britt Moser and Edvard Moser used a similar experimental setup, again with rats. In their experiments, they recorded signals from neurons in the entorhinal cortex, adjacent to the hippocampus.

Acquiring navigational skills causes a redistribution of gray matter in the hippocampus as a driver's mental map of London grows larger and more detailed with experience.

nerve cells within the olfactory bulb and hippocampus of a human brain are continuously regenerated. This means that when a whiff of something sparks a memory, be it a smoky campfire or a familiar perfume, the neurons that originally encoded those sensations may no longer be with you, and the memories may now be preserved by cells that never experienced them.

At Amen Clinics, we published a study on nearly a thousand pot smokers compared to nonusers. As a group, the pot smokers showed lower blood flow in every area of the brain, especially the hippocampus (mood and memory).[16] This is clear evidence that getting stoned can cause lasting damage.

leave people vulnerable to mental illness later in life. Recent studies have used functional magnetic resonance imaging (fMRI), or brain scans, to discover specific changes in certain areas of what's called the hippocampus in the brains of young adults who have experienced abuse.

hipocampo, un grupo de neuronas con forma de caballito de mar que realiza una importante función de «ensamblaje» conectando áreas del cerebro muy separadas, que van desde las regiones dedicadas a la percepción hasta la memoria y los centros del lenguaje.

De alguna manera el hipotálamo busca la satisfacción inmediata de una serie de necesidades sin prestar demasiada atención a las consecuencias. Es un «quiero esto y lo quiero ya».

Los hipocampos, al igual que los núcleos del septo y la corteza orbitofrontal, tienen la capacidad de modular los núcleos amigdalinos.

Las amígdalas están en conexión con unas estructuras vecinas que son los hipocampos. Ambas trabajan para almacenar recuerdos de gran intensidad emocional. Las amígdalas, sobre todo la del lado derecho del cerebro, almacena la experiencia afectiva que se tuvo en un momento determinado, mientras que el hipocampo del lado derecho almacena en su banco de memoria, el lugar donde tuvo lugar aquel impacto emocional.

REM sleep has also been shown to be particularly important for enhancing our ability to retain emotional memories and for allowing the hippocampus to turn short-term memories of the day before into long-term ones (i.e., it helps make memories more permanent, leading to structural change in the brain).

Then in 1998, two reseachers, Frederick "Rusty" Gage, an American, and Peter Eriksson, of Sweden, discovered such new cells in the human hippocampus. (This discovery is described in detail in Chapter 10 of The Brain That Changes Itself.)
