Quotes About Neurons

Brain cells are normally not sensitive to light. So by introducing light-sensitive proteins into specific types of neurons, we can now selectively control that specific type of neuron by shining light in the brain.

A typical neuron makes about ten thousand connections to neighboring neurons. Given the billions of neurons, this means there are as many connections in a single cubic centimeter of brain tissue as there are stars in the Milky Way galaxy.

I have only so many foreign-language neurons. When I learned Spanish, that displaced whatever Irish was left, and then I learned German, and that displaced the Spanish, and when I learned Serbo-Croatian, that displaced the German. So I'm a bit of a muddle.

Maybe the body learns from dreams. Maybe the muscles, the neutrons, revitalize.

We might even have to hunt for the NCC down at the subcellular level, seeking mechanisms operating inside cells rather than across large neural coalitions, as is widely assumed. Indeed, some have hypothesized, as a possible NCC, all-or-none electrical events occurring in the dendritic tree of cortical neurons, a sort of handshake confirming that a bottom-up signal has encountered top-down feedback within a certain time window.

A single cell can grow 15,000 connections with its neighbors. This chain reaction of growth ensures the pathway of thought responsible for the behavior grows strong, making it easier to kick this new resource into action in the future.

If stem cells divide equally, so both daughter cells look more or less the same, each one becomes another stem cell. If the split is unequal, neurons form prematurely.

Neurons are living cells with a metabolism. And they need glucose in order to function. Glucose is the fuel of the brain, just like gasoline is the fuel of your car.

Your brain is built of cells called neurons and glia - hundreds of billions of them. Each one of these cells is as complicated as a city.

The circadian neurons are one of the few circuits in neurobiology where we have a chance to understand at multiple levels how different sets of neurons communicate with each other - including understanding the wiring rules, the biochemical rules, and the functional behavioral rules.

Sleep is a regenerative process where we heal and where our neurons build strong connections. It's like a fountain of youth that we dive into every night.

With its billions of interconnected neurons, whose interactions change from millisecond to millisecond, the human brain is an archetypal complex system.

In the brain, you have connections between the neurons called synapses, and they can change. All your knowledge is stored in those synapses.

I found some way to recovery. But I know, have always known, that I could go back. Mysterious neurons collide and break. The brain bruises. Memories you thought were buried rise up.

How can we account for long-term memory", van Lommel asks, "if the molecular makeup of the cell membrane of neurons is completely renewed every two weeks and the millions of synapses in the brain undergo a process of constant adaptation?"15

Patiti, voleti, biti sre?an, nesre?an: sve se dešavalo unutra, u misteriji našeg mozga, medu milijardama neurona. Želja, se?anje, strah, agresivnost, misao, san, zavisili su delom od lu?enja razli?itih hemijskih supstanci, neurotransmitera, zaduženih za prenos poruka od jednog do drugog neurona.

Just like the brain consists of billions of highly connected neurons, a basic operating unit in a neural network is a neuron-like node. It takes input from other nodes and sends output to others.

In my view, while the single neuron is the basic anatomical and information processing-signaling unit of the brain, it is not capable of generating behaviors and, ultimately, thinking. Instead, the true functional unit of the central nervous system is a population of neurons, or neural ensembles or cell assemblies.

In the human mind, the number of possible connections that can be made between neurons greatly exceeds the number of atoms in the universe.

We are all now connected by the Internet, like neurons in a giant brain.

In one second of time, the conscious mind utilizes two thousand neurons. In the same second, you subconscious mind utilizes four billion neurons

Unlike the heart or kidney, which have a small, defined set of cell types, we still do not have a taxonomy of neurons, and neuroscientists still argue whether specific types of neurons are unique to humans. But there is no disputing that neurons are only about 10 percent of the cells in the human brain.

We have found that fusions of GFP with the RING finger domains of certain E3 ubiquitin ligases creates an unstable GFP. We have used unstable GFP to learn how disruption of microtubules in the touch receptor neurons causes a generalized reduction in protein levels in the cells.

The fact that three-fifths of an octopus' neurons are not in their brain, but in their arms, suggests that each arm has a mind of its own.
