Prefrontal Cortex Quotes & Sayings

Meditation is blossoming of the prefrontal cortex to overcome the momentum of the nature. It is coming out of the loops of memories, patterns,fears, dreams and anger. — Amit Ray

If [t]he mind is a system with many parts, then an innate desire is just one component among others. Some faculties may endow us with greed or lust or malice, but others may endow us with sympathy, foresight, selfrespect, a desire for respect from others, and an ability to learn from our own experiences and those of our neighbors. These are physical circuits residing in the prefrontal cortex and other parts of the brain, not occult powers of a poltergeist, and they have a genetic basis and an evolutionary history no less than the primal urges. It is only the Blank Slate and the Ghost in the Machine that make people think that drives are "biological" but that thinking and decision making are something else. — Steven Pinker

Bring your dopamine or adrenaline level down by activating other regions of the brain other than the prefrontal cortex. — David Rock

In a sense, yes, but I have another concern that is a more imminent threat that is occupying the vast majority of my prefrontal cortex."
"I'm guessing that's part of the brain."
"In rudimentary terms it's the area of the brain where we make decisions."
Brandon scrunched up his face and pressed his finger into his cheek. "What does rudimentary mean?"
"It means
"
"I'm kidding, Professor." Brandon laughed and punched Marcus playfully in the arm. "I did go to school for a few years, you know. — James L. Rubart

You never want one thing at any given moment of life. Your mind always comes up with at least two choices. If your limbic system wins, the choice you make seems to be pleasurable at first but in the long run ends up being the wrong one. And if your prefrontal cortex wins the choice you make may appear rough at first, but in the long run it turns out to be the right one. — Abhijit Naskar

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

How do we regulate our emotions? The answer is surprisingly simple: by thinking about them. The prefrontal cortex allows each of us to contemplate his or her own mind, a talent psychologists call metacognition. We know when we are angry; every emotional state comes with self-awareness attached, so that an individual can try to figure out why he's feeling what he's feeling. If the particular feeling makes no sense - if the amygdala is simply responding to a loss frame, for example - then it can be discounted. The prefrontal cortex can deliberately choose to ignore the emotional brain. — Jonah Lehrer

Recent brain scans have shed light on how the brain simulates the future. These simulation are done mainly in the dorsolateral prefrontal cortex, the CEO of the brain, using memories of the past. On one hand, simulations of the future may produce outcomes that are desirable and pleasurable, in which case the pleasure centers of the brain light up (in the nucleus accumbens and the hypothalamus). On the other hand, these outcomes may also have a downside to them, so the orbitofrontal cortex kicks in to warn us of possible dancers. There is a struggle, then, between different parts of the brain concerning the future, which may have desirable and undesirable outcomes. Ultimately it is the dorsolateral prefrontal cortex that mediates between these and makes the final decisions. (Some neurologists have pointed out that this struggle resembles, in a crude way, the dynamics between Freud's ego, id, and superego.) — Michio Kaku

evidence from functional magnetic resonance imaging showing that patients with BPD have hyperactivity in the limbic areas of the brain, especially the amygdala, and hypoactivity in the prefrontal cortex [and] in complex interaction with childhood trauma common among borderline patients, can result in the . . . behavior recognized as the symptoms of BPD: impulsive aggression, lack of affective control, and a profound mistrust born out of early disruption in the development of emotional attachment.8 Obviously, psychological theories for BPD — Cathy Wiseman

Become loving and become courageous. Become the inspiration which you seek outside. Bring the metaphorical heart of your limbic system in sync with the analytical powerhouse of the prefrontal cortex. From your mind shall rise the inspiration. From your mind shall rise the love. From your mind shall rise the greatest education of all. — Abhijit Naskar

Although a child's brain has reached 90 percent of its full size by age six, it's far from fully developed, and there are specific parts of the brain that have the furthest to go. It is the newest brain region, the prefrontal cortex, responsible for executive functioning - including voluntary attention and metacognition - that still has years of growth ahead. Your child's behavior will be marked by impulsiveness and inconsistency for quite some time to come. — Anonymous

Training in rapid acoustic discrimination can apparently induce the left prefrontal cortex, which is normally attuned to fast-changing acoustic stimuli but is disrupted in dyslexics, to do its job. The region, even in adults, remains "plastic enough...to develop such differential sensitivity after intensive training," the scientists concluded. — Jeffrey M. Schwartz

Despite their differences, pride, shame, and guilt all activate similar neural circuits, including the dorsomedial prefrontal cortex, amygdala, insula, and the nucleus accumbens. Interestingly, pride is the most powerful of these emotions at triggering activity in these regions - except in the nucleus accumbens, where guilt and shame win out. This explains why it can be so appealing to heap guilt and shame on ourselves - they're activating the brain's reward center. — David D. Burns

In brain scans, music lights up the medial prefrontal cortex and triggers a memory that starts playing in your mind. All of a sudden you can see a place, a person, an incident. The strongest responses to music - the ones that elicit vivid memories - cause the greatest activity on brain scans. — Jodi Picoult

The relationship between the prefrontal cortex and the amygdala fundamentally changes with meditation. — Jim Yong Kim

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

Kris was in black running shorts and a tight gray T-shirt constructed from some sort of magical material that clung to his muscles and triggered a gush of epinephrine while her amygdala attempted to reconcile two conflicting signals from her prefrontal cortex: attraction and revenge. "All — Sarah Strohmeyer

Multitasking has been found to increase the production of the stress hormone cortisol as well as the fight-or-flight hormone adrenaline, which can overstimulate your brain and cause mental fog or scrambled thinking. Multitasking creates a dopamine-addiction feedback loop, effectively rewarding the brain for losing focus and for constantly searching for external stimulation. To make matters worse, the prefrontal cortex has a novelty bias, meaning that its attention can be easily hijacked by something new - the proverbial shiny objects — Daniel J. Levitin

Every single decision of your life is predicated on the healthy functioning of the prefrontal cortex. Even a slight malfunction in a tiny chunk of neuron anywhere in the PFC would lead to the mental deficit in your logical decision-making. — Abhijit Naskar

The part of the brain most affected by early stress is the prefrontal cortex, which is critical in self-regulatory activities of all kinds, both emotional and cognitive. As a result, children who grow up in stressful environments generally find it harder to concentrate, harder to sit still, harder to rebound from disappointments, and harder to follow directions. And that has a direct effect on their performance in school. — Paul Tough

I did not know that my entire personality, my entire being, could be discarded as the byproduct of my anatomy. What if I really am just someone with a large prefrontal cortex ... and nothing more? — Veronica Roth

Then there are the metabolic costs of switching itself that I wrote about earlier. Asking the brain to shift attention from one activity to another causes the prefrontal cortex and striatum to burn up oxygenated glucose, the same fuel they need to stay on task. And the kind of rapid, continual shifting we do with multitasking causes the brain to burn through fuel so quickly that we feel exhausted and disoriented after even a short time. We've literally depleted the nutrients in our brain. This leads to compromises in both cognitive and physical performance. Among other things, repeated task switching leads to anxiety, which raises levels of the stress hormone cortisol in the brain, which in turn can lead to aggressive and impulsive behaviors. By contrast, staying on task is controlled by the anterior cingulate and the striatum, and once we engage the central executive mode, staying in that state uses less energy than multitasking and actually reduces the brain's need for glucose. — Daniel J. Levitin

they found considerable plasticity from the onset of puberty into the early twenties. Once this was discovered, it became obvious that the upheavals of adolescence and early adulthood coincide with a previously unrecognized sensitive period of brain maturation in the prefrontal cortex — Louis Cozolino

The point is that by exercising your capacity for forethought and planning, you strengthen your prefrontal cortex and its connection to the ventral striatum. — Anonymous

Decision-making compresses trial-and-error learning experiences into an instantaneous mental evaluation about what the consequence of a particular action will be for a given situation. It requires the on-line integration of information from diverse sources: perceptual information about the stimulus and situation, relevant facts and experiences stored in memory, feedback from emotional systems and the physiological consequences of emotional arousal, expectations about the consequences of different courses of action, and the like. This sort of integrative processing, as we've seen is the business of working memory circuits in the prefrontal cortex. In chapters 7 and 8 , we discussed the role of the prefrontal cortex in working memory and considered the contribution of the lateral and medial prefrontal cortex. Here, we will focus on two of the subareas of the medial prefrontal cortex in light of their relation to the motive circuits outlined above. — Joseph E. Ledoux

The limbic system explodes during puberty, but the prefrontal cortex keeps maturing for another 10 years. — Robin Marantz Henig

The parts of the brain corresponding to the limbic system (thought to respond only to more visceral, immediate rewards) were activated only when the decision involved comparing a reward today with one in the future. In contrast, the lateral prefrontal cortex (a more "calculating" part of the brain) responded with a similar intensity to all decisions, regardless of the timing of the options. Brains that work like this would produce a lot of failed good intentions. And indeed, we do see a lot of those, from New Year's resolutions to gym memberships that lie unused. — Abhijit V. Banerjee

I've already revealed my favorite way to get in touch with my future self: through the Rule of 3. In the Rule of 3, your future self takes center stage. By mentally fast-forwarding to the end of the day and thinking about what you want to accomplish, you activate the planning centers in your prefrontal cortex, while you also step into the shoes of your future self. And you do the same when you plan out your three accomplishments at the start of every week. — Chris Bailey

(When we force a smile, we activate facial muscles with our prefrontal cortex. But when we smile because we are in a good mood, our nerves are controlled by our limbic system, which activates a slightly different set of muscles. Our brains can tell the subtle difference between the two, which was beneficial for our evolution.) — Michio Kaku

The good part about having a mental disorder is having a valid reason for all the stupid things we do because of a damaged prefrontal cortex. However, the best part is seeing someone completely sane do the exact same things, without a valid excuse. This is the great equalizer of God and his little gift for all us crazy people to enjoy. — Shannon L. Alder
