So, the fabric of the brain, even though your brain may be smaller, bigger, it may have different types of neurons, different morphologies of neurons, we actually do share the same fabric.

The brain contains very few cells that produce orexin in a human brain, about 10,000 to 20,000 neurons in the hypothalamus.

The unique character of both individual neurons and neurons within a collection of the brain are driven by fundamental properties of their underlying biochemistry.

And in this slide you see the neurons and the synapses of the brain don't form.

If we model smell on local terms, we can trace how nasal neurons interact with scent particles, sending signals through a network of other neurons to the brain.

Our brain is made up of billions of active neurons, around 170,000 km of combined axon length.

This activity of the drug on brain neurons is thought to be responsible for its antidepressant effects.

There are these newly identified neurons, mirror neurons, that act like a neuro Wi Fi, activating in our brain exactly the areas activated in theirs. We feel with automatically.

The signals that you are seeing here are action potential, are the same signals that the neurons of my brain, of our brain, use to exchange information.

What they do is they introduce a noise into the brain so that the neurons cannot understand each other.

The nasal cavity is unique, as the only place where brain cells (neurons) are directly exposed to the environment.

In other areas of the brain, viable human neurons have been recovered and grown in culture hours after clinical death.

Your connectome is far more complex than this because your brain contains 100 billion neurons and 10,000 times as many connections.

The pullback sequence from within the brain to the outside of the skull included neurons, action potentials, and a hair follicle.

A wetware computer is an organic computer (also known as an artificial organic brain or a neurocomputer) built from living neurons.

Orexin neurons are found in the hypothalamus but project to many parts of the brain, including several areas that regulate wakefulness.

The most vulnerable cells in the brain, CA1 neurons of the hippocampus, are fatally injured by as little as 10 minutes without oxygen.

Hebbian theory is a theory in neuroscience that proposes an explanation for the adaptation of neurons in the brain during the learning process.

Pyramidal neurons (pyramidal cells) are a type of neuron found in areas of the brain including the cerebral cortex, the hippocampus, and the amygdala.

Now, one recent discovery that has been made by researchers in Italy, in Parma, by Giacomo Rizzolatti and his colleagues, is a group of neurons called mirror neurons, which are on the front of the brain in the frontal lobes.

Animal studies have shown that the stress hormone cortisol, together with neurotransmitters in the brain, also plays an important role in the remodeling of neurons.

This remodeling includes limited replacement of neurons in the hippocampus, a brain region important for spatial memory and memory of events in our daily lives.

So if we give you a specification, this brain, which is autonomous, have 500 million nerve cells, 100 million neurons so around the size of a cat brain, so there sleeps a little cat thinks for itself, optimizes whatever it digests.

Rats that have had the motor neurons in the brain stem disconnected from the neural circuits of the cerebral hemispheres (decerebration), are unable to approach and eat food.

Neurons ... communication.

So when we look at the brains of these animals, on the top panel you see the alignment of 125 cells showing what happens with the brain activity, the electrical storms, of this sample of neurons in the brain when the animal is using a joystick.

This is a tool that lets us pass a magnetic pulse through somebody's skull, into a small region of their brain, and temporarily disorganize the function of the neurons in that region.

Exposure to excessive sound kills hair cells, and studies have shown as hair cells are lost, different neurons are activated, activating auditory parts of the brain and giving the perception of sound.

However, studies determined that environmental changes could alter behavior and cognition by modifying connections between existing neurons and via neurogenesis in the hippocampus and other parts of the brain, including the cerebellum.

Neural stem cells The existence of stem cells in the adult brain has been postulated following the discovery that the process of neurogenesis, the birth of new neurons, continues into adulthood in rats.

In the computer, you have all the data going through the central processing unit, and any piece of data basically has to go through that bottleneck, whereas in the brain, what you have is these neurons, and the data just really flows through a network of connections among the neurons. There's no bottleneck here.

And if we can do that, the sequence of the neurons we recover from that unscrambling will be a prediction of the pattern of neural activity that is replayed in the brain during memory recall.

Afferent neurons communicate with specialized interneurons.

These cells are modified postganglionic neurons.

Activation of these neurons increases dopamine and norepinephrine in these areas, and excites histaminergic tuberomammillary neurons increasing histamine levels there.

He generated neurons from these induced pluripotent stem cells from patients who have Lou Gehrig's Disease, and he differentiated them into neurons, and what's amazing is that these neurons also show symptoms of the disease.

So this is how close your mental experience and the activity of the neurons in the retina, which is a part of the brain located in the eyeball, or, for that matter, a sheet of visual cortex.

Did you know you have functioning neurons in your intestines about a hundred million of them? Food scientist Heribert Watzke tells us about the hidden brain in our gut and the surprising things it makes us feel.

Ed Boyden A light switch for neurons

VS Ramachandran The neurons that shaped civilization

When your neurons are replaced, they change.

He took 20,000 and then 60,000 disaggregated rat neurons so these are just individual neurons from rats put them on a chip.

Now this is a map, down in the surface of the brain, in which, in a very elaborate experiment we've reconstructed the responses, location by location, in a highly detailed response mapping of the responses of its neurons.

And we did that for tens of thousands of neurons, built digital models of all the different types of neurons we came across.

Moreover, once we can do that, we can actually activate specific neurons or we can destroy or inhibit the activity of those neurons.
