Quotes About Brain

You are your synapses

Fear and anxiety are not biologically wired. They do not erupt from a brain circuit in a prepackaged way as a fully formed conscious experience. They are a consequence of the cognitive processing of nonemotional ingredients. They come about in the brain the same way any other conscious experience comes about but have ingredients that nonemotional experiences lack.108

Fear and other emotions are based on assumptions, presuppositions, and expectations; they are constructed in the brain from nonemotional ingredients.

No doubt one of the reasons human cognition is so powerful is because we have language in our brains, which exponentially increases the ability to categorize information, to chunk. A whole culture, for instance, can be implied by a name.

Every human being has billions of neurons that together make trillions of synaptic connections among one another. Chemicals are oozing and sparks flying constantly, during wakefulness and during sleep, during thoughtfulness and during boredom. At any one moment, billions of synapses are active.

The general view that prefrontal and parietal networks are required for conscious perceptual experiences is supported by studies of patients as they begin to recover from coma.157 They first transition to a vegetative state in which the brain stem and basal forebrain networks of arousal are functionally active, but the frontal and parietal networks are not. Although

Language is not just a system for talking and reading. Talking and reading reflect the cognitive elaborations brought into the brain by language.

The same network is suppressed in states of hypnosis, in which the person is fully awake and responsive, but external awareness is altered (by way of hypnotic suggestion, attention to certain stimuli can be diminished).

It should be noted that psychological processes and learning experiences are, in the end, also biological in nature, because they are products of the brain and as such are also subject to genetic influences and the influence of gene-environment interactions, or what is called epigenetics.

My notion of personality is pretty simple: it's that your "self," the essence of who you are, reflects patterns of interconnectivity between neurons in your brain.

the amygdala itself is a recipient of neuromodulatory inputs means that its processing is also boosted during arousal. As the amygdala drives arousal and arousal in turn drives the amygdala, a self-sustaining reentrant loop is engaged that helps keep the brain and body revved up as long as the threat remains.75

The essence of who you are is stored as synaptic interactions in and between the various systems of your brain. As we learn more about the synaptic mechanisms of memory, we learn more about the neural basis of the self.

This in no way implies the existence of multiple executives, each with their own planning and decision-making capacities. Instead, it suggests that the various component executive functions are achieved by a set of interconnected circuits that are spread over several brain regions in the frontal cortex, and even other regions,

I see you've taken an interest in Whitekit," Goosefeather observed as they climbed a leafy slope. "He's my kin," she mewed. "So am I," he reminded her, "but you don't visit me." That's because you've got bees in your brain.

In a way, these old role-playing games had been the first virtual-reality simulations, created long before computers were powerful enough to do the job. In those days, if you wanted to escape to another world, you had to create it yourself, using your brain, some paper, pencils, dice, and a few rule books.

O que acontece depois da morte? Bem, não sabemos ao certo. Mas as evidências sugerem que não acontece nada. Você morre, seu cérebro para de funcionar e você some e deixa de fazer perguntas irritantes.

What happens when you die? Well, we're not completely sure. But the evidence seems to suggest that nothing happens. You're just dead, your brain stops working, and then you're not around to ask annoying questions anymore

All sensory input received by their brain is digitized and stored as a .oni (dot-oh-en-eye) file on an external data drive attached to their headset.

We are thus faced with the following question: Why should an organ like our brain, with the sensorial system attached to it, of necessity consist of an enormous number of atoms, in order that its physically changing state should be in close and intimate correspondence with a highly developed thought?

In presuming that knowledge is a mental activity we tend to think of our body strictly as a mindless container—an object. Of course, we understand that our senses take in information and our brains process it. But we see this as mechanical. We actually think computers might duplicate how humans know.

Pessimism is the night-side of thought, a melodrama of the futility of the brain, a lyricism written in the graveyard of philosophy.

Why do we all know so much? And why do we feel the unbearable urge to tell each other that we know so much? It's as if we are burdened by the question of what to do with thought, by our brains, by the very weight of the organ…

In the long term, the fragmentation of attention, a breaking up of focus and mental continuity, can disrupt neural connections in the brain and eventually lead to a literally 'shallower' neurological structure. It makes us – on the physiological level of the brain, as well as of the mind – less capable of concentration and continuous thought.

The central idea of this book is that the self is a process, not a thing or an entity. The self isn't something outside experience, hidden either in the brain or in some immaterial realm.
