Sentences with phrase «hypocretin neurons»

This is coupled by ghrelin activity, which is also detected by Hypocretin Neurons.

Hypocretin Neurons express leptin receptors.

In animals, Hypocretin Neurons serve an important evolutionary function.

It means that Hypocretin Neurons are instead always acted upon by mostly uniform — excitatory — signals they receive.

GABA neurons also create a bridge between Neuropeptite Y, which is the molecule that arguably has the strongest appetite - stimulating effect on the brain, and Hypocretin Neurons (more on Neuropeptide Y later this week).

Ghrelin, which originates in the gut and is known to stimulate appetite, also excites Hypocretin Neurons.

Hypocretin Neurons only ever up - regulate and relax.

Moreover, some recent complicated neurobiological work done on mice has shown that injecting them with leptin decreases the activity of their Hypocretin Neurons.

One notable source of excitation is corticotrophin releasing hormone, which suggests that stress activates the activity of Hypocretin Neurons.

Hypocretin neurons wake animals up.

Because 1) Hypocretins simultaneously stimulate appetite and wakefulness, particularly through orexigenic output of the melanocortin system, and subsequent release of CRH, which activates the stress response, and 2) while Hypocretin Neurons wake us up, they also need to be quiet enough for people to go to sleep.

It seems as though Hypocretin Neurons may act as a nexus of signal input for the appropriate synchronization of various autonomic, endocrine, and metabolic processes.

Hypocretin Neurons may serve as one of the answers to the question of exactly how that phenomenon comes about.

Hypocretin Neurons demonstrate why so many people have difficulty with their appetite and their sleep.

And normally, Hypocretin Neurons respond quickly to changes in input.

From there, Hypocretin Neurons project to all regions of the brain, including the hypothalamus, cerebral cortex, brain stem, and spinal cord.

Hypocretin Neurons upregulate the production of molecules down several other pathways, too: these include noradrenergic, histaminergic, cholinergic, dopamine, and serotonergic.

If it is detecting lowered leptin (and other hormone) levels in the blood, it does several things: it up - regulates hunger signalling, it emphasizes sweet foods in doing so (partly why so many disordered eaters struggle with carbohydrates in particular), and it sends activation signals to hypocretin neurons.

Research is beginning to show that Hypocretin Neurons are excited by excitatory synaptic currents and asymmetric synapses with minimum inhibitory input.

Hypocretin neurons are one way in which intermittent fasting may dysregulate a woman's normal hormonal function.

Hypocretin Neurons play the role both of trigger and of accelerator, taking states of wakefulness, insomnia, stress, and obesity into continual positive feedback loops.

Hypocretin neurons, about which I have also written before, up - regulate wakefulness and the stress response.

For example, orexin / hypocretin levels increase during sleep loss (39) and orexin / hypocretin neurons are an important component of sleep — wakefulness and feeding neural systems (40, 41).

Hypocretin neurons are one way in which intermittent fasting may dysregulate a woman's system.»

Hypocretin neurons have the ability to incite energetic wakefulness, and to prevent a person from falling asleep, should his body detect a «starved» state.

Scientists hypothesized that the problem with S. pyogenes might be «molecular mimicry,» in which a molecular pattern on the bacterium resembles proteins on those hypocretin neurons.

Three groups independently studying people with narcolepsy identified antibodies against the same protein, tribble 2, that's found on hypocretin neurons.

They focused this effect on the hypocretin neurons, which are brain cells in the lateral hypothalamus.

What does feeding do, then, for Hypocretin Neuron excitation?

What this means is that Hypocretin Neuron activity is stimulated in part by decreasing levels of leptin in the blood, and that increased leptin levels reduce the level of excitation running through Hypocretin Neurons.

Not exact matches

Researchers have engineered the genomes of mice so they have a light - sensitive inhibitory molecule that can shut down the wakefulness - promoting properties of neurons called hypocretin cells.

Since the late 1990s, scientists have known narcoleptics lack neurons that produce neuropeptides called hypocretins, which regulate wakefulness.

Symptoms appear only after more than 90 % of the hypocretin - producing neurons have been destroyed.

Sporadic cases can happen in any breed and is caused by a loss of hypocretin 1 - producing neurons in the hypothalamus.
