Sentences with phrase «neurons produce more of»

Using mice, this study found that in obesity, CB1 cannabinoid receptors become enriched on the nerve terminals that normally inhibit orexin neuron activity, and the orexin neurons produce more of the endocannabinoids to activate these receptors.

Not exact matches

Zimmer: Yeah, so the neurons are growing in the child's brain and they are making more and more of these connections and then cutting them back, so you know, it's possible that they are cutting back these connections to produce a very efficient network.

The reason, Del Percio argues, is that the brains of athletes are more efficient, so they produce the desired result with the help of fewer neurons.

«Neurons become increasingly more complex in their extensions and connections as the brain matures, and the maturational delays reported previously in animal models and human behavioral studies of iron deficiency would predict that lower iron intake would produce neurons in cortical gray matter that are structurally less complex and more imNeurons become increasingly more complex in their extensions and connections as the brain matures, and the maturational delays reported previously in animal models and human behavioral studies of iron deficiency would predict that lower iron intake would produce neurons in cortical gray matter that are structurally less complex and more imneurons in cortical gray matter that are structurally less complex and more immature.

Their answer, garnered through a series of electrophysiology, dendritic spine density and immunohistochemistry experiments with mice that were genetically altered to produce either more new neurons or kill off newborn neurons, supports the second model — some of the cortical neurons transfer their connections from mature granule cells to the new granule cells.

Psychologists suspect that the mathematical intuition that these neurons help produce lays the foundation for all of our more sophisticated kinds of math.

Still, when the brain cells and spinal cord cells of these babies were examined at autopsy, there was clear evidence that nusinersen had tricked SMN2 into producing a great deal more of the full length, motor neuron - protecting protein: two to six times more copies of SMN's messenger RNA were found in spinal cord samples from nusinersen - treated babies than in autopsy samples from untreated infants.

In studies of neural development in mice, Stahl found that TRNP1 produces a protein that determines whether neural stem cells self - replicate, leading to a balloonlike expansion of cortical surface area, or whether they differentiate into a plethora of intermediate stem cell types and neurons, thickening the cortex and forming more complex brain structures.

«Even so, the computer model we used allowed us to characterize, and more importantly quantify, key features of how neurons produce these signals,» says Anastassiou.

Some individual neurons, targeted with millisecond pulses of light, produced more than 3,000 action potentials over the span of thirty minutes, with no reduction in efficacy.

This is also why levodopa — the chemical building block of dopamine — is the go - to drug for PD: giving the surviving dopamine - producing neurons more building blocks allows them to eke out more dopamine, going a long way toward correcting the subset of PD symptoms that are caused by loss of dopamine - producing cells (particularly in the early stages of the disease).

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

«The fasting is a mild energetic stress and the neurons respond adaptively by increasing mitochondria which helps them produce more energy and... by increasing the number of mitochondria and neurons it can increase the ability of the neurons to form and maintain synapses and thereby increase learning and memory ability.

They help produce more neurotransmitters and really optimize the expression of these neurotransmitters to where we get good sensitivity between the neurons.
