Hippocampus Quotes

The relevance of these special properties of the hippocampus and their role in map learning comes from a consideration of the massive upsurge in our use of technology for wayfinding. By focusing on the blue dot of a phone map, rather than looking about at our surroundings and making the effort to form a genuine map, we are short-circuiting the processes that we've learned to use over previous millennia. As far as finding our way is concerned, we have become striatal stimulus-response machines, racing through time and space like feverish maze mice hunting for cheese. ~ Colin Ellard

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

At every level, from the microcellular to the psychological, exercise not only wards off the ill effects of chronic stress; it can also reverse them. Studies show that if researchers exercise rats that have been chronically stressed, that activity makes the hippocampus grow back to its preshriveled state. The mechanisms by which exercise changes how we think and feel are so much more effective than donuts, medicines, and wine. When you say you feel less stressed out after you go for a swim, or even a fast walk, you are. ~ John Ratey

Altogether, these observations suggest that several processes contribute to psychotic experience: the loss of familiarity with the world, hypothetically associated with noisy information processing; increased novelty detection mediated by the hippocampus; associated alterations of prefrontal cortical processing, which have reliably been associated with impairments in working memory and other executive functions; increased top-down effects of prior beliefs mediated by the frontal cortex that may reflect compensatory efforts to cope with an increasingly complex and unfamiliar world; and finally disinhibition of subcortical dopaminergic neurotransmission, which increases salience attribution to otherwise irrelevant stimuli. Furthermore, increased noise of chaotic or stress-dependent dopamine firing can reduce the encoding of errors of reward prediction elicited by primary and secondary reinforcers, thus contributing to a subjective focusing of attention on apparently novel and mysterious environmental cues while reducing attention and motivation elicited by common and natural and social stimuli. ~ Andreas Heinz

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

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. ~ Steven Kotler

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

[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

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

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

Rage swallowed remorse. Rage drop-kicked self-pity. Rage murdered sorrow. And then, like blood-red wine tucked into the refrigerator, rage chilled to become cold, calculating anger. Anger was a creature that arrived on her doorstep with a suitcase full of strategy and vengeance. It tipped its hat at her and hopped into her brain. It knocked on the Logic Department's door. It found a broken mirror somewhere in the crevices between her hippocampus and her hypothalamus, and it was wondering if somebody had misplaced it.

No retaliation? It scoffed. Think again, missy. ~ Angela Panayotopulos

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

When the sunlight hit the trees, all the beauty and wonder come together. Soul unfolds its petals. Flowering and fruiting of plants starts. The birds song light up the spinal column and harmonize the hippocampal functioning. ~ Amit Ray

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

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

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

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

Reyna put her hand on his shoulder. 'Coach, we'll get you to your wife, but let's do it right. Tyson, how did you and Ella get out to this ship?'
'Rainbow!'
'You … took a rainbow?'
'He is my fish pony friend.'
'A hippocampus,' Nico advised. ~ Rick Riordan

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

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

There is some evidence that chronic severe depression causes some atrophy or shrinkage in the hippocampus. Depressive illness could therefore be seen as a very subtle form of degeneration in some nerve cells. ~ Stefan Cembrowicz

Researchers like Jonathan Winson, Gyorgy Buzsaki, Bruce McNaughton, and Matt Wilson believe memory consolidation occurs during sleep, and specifically that it is during sleep that the slow interleaving of information into cortical networks takes place. Recent studies support this notion. For example, Wilson and McNaughton recorded the activity of neurons in the rat hippocampus. Using technically sophisticated procedures, they were able to identify precise patterns of cell activity in the hippocampus as rats explored a novel environment. Subsequently, when the rats went to sleep, the neural patterns seemed to be repeated in the hippocampus, as if the rats were dreaming about the places they had explored. This is an impressive finding. Although it has not yet been demonstrated that the hippocampal playback during sleep is actually read and used by the cortex, the existing data are consistent with the possiblity. ~ Joseph E. LeDoux

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

The three years it takes to acquire 'the knowledge' and the subsequent years of navigating London's complex streets give cabbies a 30% larger hippocampus than the average London resident. ~ James Tagg

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

hippocampus. But during frightening situations - such as a car accident or a robbery - another area, the amygdala, also lays down memories along an independent, secondary memory track.30 Amygdala memories have a different quality to them: they are difficult to erase and they can pop back up in "flashbulb" fashion - as ~ David Eagleman

A book is a vacation for the mind. My books will take you inside my mind, so feel free to make yourself at home. Do as you please, but please don't put your feet up on my hippocampus. ~ Jarod Kintz

The earliest portions to shrink are generally the frontal lobes, which govern judgment and planning, and the hippocampus, where memory is organized. As a consequence, memory and the ability to gather and weigh multiple ideas - to multitask - peaks in midlife and then gradually declines. ~ Atul Gawande

While the hippocampus itself doesn't store memories, it serves to triage our experiences based upon their survival significance. ~ David Perlmutter

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

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... ~ Michel Faber

Neuro-nonsense occurs when people take on board the supposed discoveries of neuroscience – all these brain images that tell us, for instance, that we've discovered now exactly what love is, it's this little bit in the hippocampus, so we have no need to question what the meaning of these things is. But these images have no meaning, any more than a chemical reaction in a test-tube has a meaning. All kinds of nonsense comes into being as a result of this, the nonsense being essentially what happens when our own human nature is confiscated from us by science or pseudosciences which claim to explain us without really going into the question of what we are. ~ Roger Scruton

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
