Quotes About Brain

Since long intestines and large brains are both massive energy consumers, it's hard to have both. By shortening the intestines and decreasing their energy consumption, cooking inadvertently opened the way to the jumbo brains of Neanderthals and Sapiens.1

As we mentioned in the previous chapter, scientific insights into the way our brains and bodies work suggest that our feelings are not some uniquely human spiritual quality, and they do not reflect any kind of 'free will'. Rather, feelings are biochemical mechanisms that all mammals and birds use in order to quickly calculate probabilities of survival and reproduction. Feelings aren't based on intuition, inspiration or freedom they are based on calculation.

we all know that the brain's retrieval system is amazingly efficient, except when you are trying to remember where you put your car keys.

The Human Brain Project,

Though the adult brain is more flexible and volatile than was once thought, it is still less malleable than the teenage brain. Reconnecting neurons and rewiring synapses is hard work.5 But in the twenty-first century, you can't afford stability.

The most commonly believed theory argues that accidental genetic mutations changed the inner wiring of the brains of Sapiens, enabling them to think in unprecedented ways and to communicate using an altogether new type of language.

The human collective knows far more today than did the ancient bands. But at the individual level, ancient foragers were the most knowledgeable and skilful people in history. There is some evidence that the size of the average Sapiens brain has actually decreased since the age of foraging.5

When you force yourself to laugh, you use different brain circuits and muscles than when you laugh because something is really funny. Humans cannot usually detect the difference. But a biometric sensor could.9

Some believe that if we could only crack the genetic code and map every neuron in the brain, we will know all of humanity's secrets. After all, if humans have no soul, and if thoughts, emotions and sensations are just biochemical algorithms, why can't biology account for all the vagaries of human societies?

Homo sapiens, the brain accounts for about 2–3 per cent of total body weight, but it consumes 25 per cent of the body's energy when the body is at rest. By comparison, the brains of other apes require only 8 per cent of rest-time energy.

En Homo sapiens, el cerebro supone el 2-3 por ciento del peso corporal total, pero consume el 25 por ciento de la energía corporal cuando el cuerpo está en reposo.

Los científicos no saben cómo un conjunto de señales eléctricas en el cerebro crea experiencias subjetivas. Y, lo que es más importante, tampoco saben cuál podría ser el beneficio evolutivo de semejante fenómeno. Es la mayor laguna en nuestra comprensión de la vida.

The fact is that a jumbo brain is a jumbo drain on the body. It's not easy to carry around, especially when encased inside a massive skull. It's even harder to fuel. In Homo sapiens, the brain accounts for about 2–3 per cent of total body weight, but it consumes 25 per cent of the body's energy when the body is at rest.

It turns out that our choices of everything from food to mates result not from some mysterious free will but rather from billions of neurons calculating probabilities within a split second.

A champion is strong, not just by showing it physically -but mentally, cause to achieve and become at the level he is, he needs a brain to analyze it, right?

Si le cerveau des mammifères a évolué selon une certaine voie, celui des oiseaux en a suivi une autre . Progression dynamique plutôt que stagnation reptilienne. Au lieu de se déployer à la surface en gros plis grumeleux comme chez les mammifères, leur intelligence est enfouie dans le cortex. Comment voler avec une grosse tête ? Leur cerveau est compact, renferme plus de neurones dans un petit espace que tout autre animal.

Our brain is so full of nonsense there is no room for common sense.

Every mental event has a neural correlate. Through mindfulness we can rewire the brain for peace, harmony, laughter, and love.

To think is to practice brain chemistry.

The brain, which operates on electromagnetic impulses, is as much an activity of the universe as are the electromagnetic storms in the atmosphere or on a distant star. Therefore science is one form of electromagnetism that spends it time studying another form…science is god explaining god through a human nervous system…isn't spirituality the same thing?

You won't know what your brain can do until you test its limits and push beyond them. No matter how inefficiently you are using your brain, one thing is certain: it is the gateway to your future. Your success in life depends on your brain, for the simple reason that all experience comes to us through our brains.

In our everyday lives, if we intentionally set out to learn new things or do familiar things in new ways (such as commuting to work via a new route or taking the bus instead of a car), we effectively rewire our brains and improve them. A physical workout builds muscle; a mental workout creates new synapses to strengthen the neural network.

cuando la mente desea trascender, el cerebro está dispuesto a seguirla.
