Quotes About Receptors

The complex human eye harvests light. It perceives seven to ten million colors through a synaptic flash: one-tenth of a second from retina to brain. Homo sapiens gangs up to 70 percent of its sense receptors solely for vision, to anticipate danger and recognize reward, but also—more so—for beauty.

There are actually some women in the world with four color receptor cells in their eyes, which can allow them to see 100 million colors. To put that into perspective for you, a typical human only has three color receptors and can only see about one million colors.

My wife could turn to me and she may say, 'Why do you love me?' And I can with all honesty look her in the eye and say, 'Because our pheromones matched our olfactory receptors.'

the second principle of moral psychology, which is that there's more to morality than harm and fairness. The central metaphor of these four chapters is that the righteous mind is like a tongue with six taste receptors.

Humans have taste receptor cells in the gut, the voice box, the upper esophagus, but only the tongue's receptors report to the brain.

Which is something to be thankful for," says Danielle Reed, Rawson's former colleague at Monell. Otherwise you'd be tasting things like bile and pancreatic enzymes. (Intestinal taste receptors are thought to trigger hormonal responses to molecules, such as salt and sugar, and defensive reactions—vomiting, diarrhea—to dangerous bitter items.)

The study animal of choice for taste researchers is the catfish,* simply because it has so many receptors. They are all over its skin. "Catfish are basically swimming tongues," says Rawson. It is a useful adaptation for a limbless creature that locates food by brushing up against it; many catfish species feed by scavenging debris on the bottom of rivers.

I wonder now if, as well as those millions of scent receptors, dogs also have the ability to love a whole bunch of people unconditionally, with no limits on numbers.

Truth cannot be constructed. To live in ideology is, as Havel so eloquently reminds us, inevitably to live in a lie. Truth can only be revealed. We cannot be creators, only receptors.

Her receptors were just very keen," said Pontes, "and she processes information fast and it spits out decisions and it makes people get nervous.

Women are much better than men in tactile sensitivity with their fingers, but possibly only because they have smaller hands and, therefore, a denser network of receptors.

Confident people tend to challenge themselves and compete, even when their efforts yield small victories. Small victories build new androgen receptors in the areas of the brain responsible for reward and motivation.

While I was young, getting money, a hustler, I was sharp. But I never thought I was too smart to learn something new. Keep your receptors open, and don't get too egotistical to think you know more than everybody else in the room.

She had been privileged to live outside of Time, to enter and leave at will, looting and manipulating, weightless, invisible. Now Time had claimed her again, put her under house arrest, taken her passport away. Only an animal with a full set of pain receptors after all.

Color as we perceive it is our psychophysical reaction of the nerve signal generated by the receptors of our eyes, which distinguish electromagnetic waves of different frequencies.

We see the world around us in color. What is color? Put simply, it is the frequency (the speed of oscillation) of the electromagnetic wave light is. If the wave vibrates more rapidly, the light is bluer. If it vibrates a little more slowly, the light is redder. Color as we perceive it is our psychophysical reaction of the nerve signal generated by the receptors of our eyes, which distinguish electromagnetic waves of different frequencies.

Touch' is a multi-faceted concept, reflecting the different types of receptors. The simplest are free nerve endings which detect pain and changes in temperature; slightly more complex are Merkel's tactile cells (which detect pressure); followed by Grandry bodies, which consist of two to four tactile cells and detect movement (velocity); and the lamellated Herbst corpuscles (similar to Vater-Pacinian corpuscles in mammals), which are sensitive to acceleration.

It seems odd to think of tasting without any perceptive experience, but you are doing it right now. Humans have taste receptor cells in the gut, the voice box, the upper esophagus. But only the tongue's receptors report to the brain.

Not all taste buds are located on the tongue. Some are found on the roof of the mouth and in the throat.… Taste receptors are also found in the lining of the intestine, suggesting that our concept of the sense of taste should include these chemical-sensing systems.

If you feel depressed for an hour, you've produced approximately eighteen billion new cells that have more receptors calling out for depressed-type peptides and fewer calling out for feel-good peptides.

There are some who believe that perfume is magic. The fragrance of a thing is its purest essence. And certain scents can awaken phantoms of past love, of sweetest reminiscence." "Phantoms?" Daisy repeated, intrigued, and the other girl replied impatiently. "He doesn't mean it literally, dear. Perfume can't summon a ghost. And it's not really magic. It's only a mixture of scent particles that travel to the olfactory receptors in your nose.

Advanced research along these lines has established that in each and every minute an immensely astronomical number of information bits do enter through our whole-body receptors. Additionally, during

advancing bio-neurological researchers have discovered that our neurological systems possess a gigantic number of micro-receptors, the result of which is that it is thought that every cell in our bio-bodies act as some kind of a receptor, including the cells in our bones.

After being sensed, the information, via innate electrical coding, is passed along from cell to cell, then through nervous system channels where it ends up in this or that control center which then makes "sense" of the electrical coding, and which is not always the brain. It thus turns out that the entire human body is one gigantic series of sensing systems, having, as it does, millions upon millions of sensing receptors.
