Hippocampus Brain Quotes & Sayings

Imaging studies have shown that exercise increases blood volume in a region of the brain called the dentate gyrus. That's a big deal. The dentate gyrus is a vital constituent of the hippocampus, a region deeply involved in memory formation. — John Medina

[Narratives] serve as powerful tools for high-level neural network integration. The combination of linear storyline and visual imagery woven together with verbal and nonverbal expressions of emotion activates and utilizes dedicated circuitry of both left and right hemispheres, cortical and subcortical networks, the various regions of the frontal lobes, and the hippocampus and amygdala. The cooperative and interactive activation involved in stories may be precisely what is required for scultpting and maintaining neural network integration while allowing us to combine sensations, feelings, and behaviors with conscious awareness. Further, stories link individuals into families, tribes, and nations and into a group mind linking each individual brain. It is likely that our brains have been able to become as complex as they are precisely because of the power of narratives and the group to support neural integration — Louis Cozolino

Cannabis affects the brain because brain cells themselves produce cannabis-like neurotransmitters. The first such compound to be identified was christened anandamide, ananda being Sanskrit for "bliss." The proteins that transmit anandamide's message to the brain, the receptors, are mainly located in the striatum (hence the blissful feeling) and in the cerebellum (hence the unsteady gait after taking marijuana), in the cerebral cortex (hence the problems with association, the fragmented thoughts and confusion), and in the hippocampus (hence the memory impairment). But there are no receptors in the brain stem areas that regulate blood pressure and breathing. That's why it's impossible to take an overdose of cannabis, as opposed to opiates. — D.F. Swaab

You don't have to work for Google, or any of the other firms encouraging staff to pursue personal projects on company time, to use slowness to unlock your creativity. Anyone can do it. Start by clearing space in your schedule for rest, daydreaming and serendipity. Take breaks away from your desk, especially when you get stuck on a problem. — Carl Honore

Nowadays you can record on your laptop with Pro Tools, which I do quite often. — Ronnie Wood

In your body, the gradually accumulating burden of reactive experiences is called allostatic load, which increases inflammation, weakens your immune system, and wears on your cardiovascular system. In your brain, allostatic load causes neurons to atrophy in the prefrontal cortex, the center of top-down executive control; in the hippocampus, the center of learning and memory; and in other regions. It impairs myelination, the insulating of neural fibers to speed along their signals, which can weaken the connectivity between different regions of your brain, so they don't work together as well as they should. — Rick Hanson

There's a lot of scientific evidence demonstrating that focused attention leads to the reshaping of the brain. In animals rewarded for noticing sound (to hunt or to avoid being hunted, for example), we find much larger auditory centers in the brain. In animals rewarded for sharp eyesight, the visual areas are larger. Brain scans of violinists provide more evidence, showing dramatic growth and expansion in regions of the cortex that represent the left hand, which has to finger the strings precisely, often at very high speed. Other studies have shown that the hippocampus, which is vital for spatial memory, is enlarged in taxi drivers. The point is that the physical architecture of the brain changes according to where we direct our attention and what we practice doing. — Daniel J. Siegel

Along with the violent tonic-clonic seizure, it turned out I had also been experiencing complex partial seizures because of overstimulation in my temporal lobes, generally considered to be the most "ticklish" part of the brain. The temporal lobe houses the ancient structures of the hippocampus and the amygdala, the parts of the brain responsible for emotion and memory. The symptoms from this type of seizure can range from a "Christmas morning" feeling of euphoria to sexual arousal to religious experiences. — Susannah Cahalan

Words travel, because the word arctic comes from arktos, Greek for bear. Cancer comes from the Greek word for crab, karkinos. Memory, or one of its locations in the brain, the hippocampus, means seahorse. A bestiary is buried in our language. — Rebecca Solnit

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?' — John O'Keefe

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. — Siri Hustvedt

An accident of brain development stacked the deck against children: the mother had three or four years to fuck with your head before your hippocampus began recording lasting memories. You'd been talking to your mom since you were one year old and listening to her for even longer, but you couldn't remember a single word of what you or she had said before your hippocampus kicked into gear. Your — Jonathan Franzen

The recorder consisted of a biochip smaller than the head of a pin implanted into the hippocampus and nanosensors embedded throughout the body. Normally, the system lay dormant. But as soon as it detected severe deviations from the norm in various brain activity parameters - indicative of the stress caused by imminent death or great danger - the black-box would automatically contact the police and record the short-term memory in the hippocampus via molecular scanning. In the event of death, about one to two minutes of memories preceding the cessation of brain activity could be decrypted from the black box. — Bao Shu

Emily said ... Well, I read that it's important to sleep. While you sleep, the hippopotamus in your brain replays things that happend during the day, e.g. what you studied. So therefore it remembers it for you. — Jaclyn Moriarty

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. — Sam Kean

However, another brain structure, located near the hippocampus, matures quite early and can store the emotional component of trauma, though not the memories themselves. This structure is the almond-shaped amygdala, which also comes in pairs. Very young children who have experienced trauma may have no memory of the trauma, but the trauma is encoded in the amygdala. When — Jane Gilgun

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. — Michio Kaku

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). — Norman Doidge

Growing older is an opportunity for you to increase your value and competence as the neural connections in your hippocampus and throughout your brain increase, weaving into your brain and body the wisdom of a life well lived, which allows you to stop living out of fear of disappointing others and being imperfect. Ageless living is courageous living. It means being undistracted by the petty dramas of life because you have enough experience to know what's not worth worrying about and what ought to be your priorities. — Christiane Northrup

Neuroscience may one day resolve how planning takes place. The first hints are coming from the hippocampus, which has long been known to be vital both for memory and for future orientation. The devastating effects of Alzheimer's typically begin with degeneration of this part of the brain. As with all major brain areas, however, the human hippocampus is far from unique. Rats have a similar structure, which has been intensely studied. After a maze task, these rodents keep replaying their experiences in this brain region, either during sleep or sitting still while awake. Using brain waves to detect what kind of maze paths the rats are rehearsing in their heads, scientists found that more is going on than a consolidation of past experiences. — Frans De Waal

Elegance has nothing to do with fashion. — Karl Lagerfeld

This is why, in a nutshell, advice is overrated. I can tell you something, and it's got a limited chance of making its way into your brain's hippocampus, the region that encodes memory. If I can ask you a question and you generate the answer yourself, the odds increase substantially. — Michael Bungay Stanier

With books we stand on the shoulders of giants. — John Locke

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. — David Perlmutter

The hippocampus is the structure where memory is supposedly controlled. It is the most plastic part of the brain; it is also the part that is assumed to absorb all the damage from repeated insults like the chronic stress we experience daily from small doses of negative feelings - as opposed to the invigorating "good stress" of the tiger popping up occasionally in your living room. You can rationalize all you want; the hippocampus takes the insult of chronic stress seriously, incurring irreversible atrophy. Contrary to popular belief, these small, seemingly harmless stressors do not strengthen you; they can amputate part of your self. — Nassim Nicholas Taleb

That is what a book is: a million little things, a thousand feelings, hundreds of experiences, all melted together and sculpted into a book-shaped vessel. — Beth Revis

Kirk Erickson and colleagues in Art Kramer's lab hypothesized that the well-documented shrinkage of the brain with age would be reduced by exercise. They used structural scans to measure hippocampal volume in 165 healthy older people who varied in their level of physical fitness. The hippocampus is a structure deep in the temporal lobes long known to be critical for forming new memories. They found that people who showed higher aerobic fitness had larger hippocampi bilaterally. Moreover, the fitter group also showed better spatial memory performance than the less fit group. — Pamela M. Greenwood
