Not exact matches

Using human fetal «mini-brains» grown in 3 - D cultures, scientists determined that a specific protein produced by the Zika virus changes the properties of neural stem cells in the developing brain of an infected fetus, potentially causing microcephaly in newborns (Ki - Jun Yoon, abstract 103.06, see attached summary).

He was paralyzed, but the moment he thought about using his hand, we saw changes in neural activity in the specific part of the motor cortex associated with hand movement.

By combining SNP - targeting allele - specific silencing and gain - of - function approaches, we showed that a 46 - glutamine expansion in human HTT was sufficient for a dominant - negative effect on spindle orientation and changes in the distribution within the spindle pole and the cell cortex of dynein, p150Glued and NuMA in neural cells.

A comparison wa made between their behavior change from the beginning to the finish of the research with neural activity in a specific brain region which a previous study had indicated is predictive of behavior change.

Joint angle - specific strength gains at shorter muscle lengths tend to be caused by changes in neural drive (Noorkõiv et al. 2014).

Changes in neural drive after explosive contraction and maximal (sustained) contraction strength training are specific to the contraction duration (Balshaw et al. 2016).

This pain can not be traced back to a specific cause such as an infection, inflammatory skin disease, neural irritation, trauma, surgery or hormonal changes (2).

The reason for the difference between the changes in joint angle - specific strength and the changes in joint angle - specific neural drive is that both peripheral and central factors are operating, and the impact of joint angle - specific neural drive is greater after training at short muscle lengths, while the impact of peripheral factors (like regional muscle size and / or muscle fascicle length) are greater after training at long muscle lengths.

In one study, Remaud et al. (2010) assessed joint angle - specific changes in maximum voluntary isometric contraction (MVIC) torque and in neural drive after isotonic and isokinetic types of external load, using knee extension training.

If this is the case, we should find that the main causes of specificity in strength gains after training with different types of external load are regional hypertrophy and joint angle - specific changes in neural drive (especially at end range of motion).

This is in line with the expected effects of joint angle - specific changes in neural drive being most relevant at short muscle lengths.

This specificity is likely attributable to differences in regional hypertrophy (which may be a function of different increases in muscle fascicle length) and joint angle - specific changes in neural drive, just like partial and full range of motion training.

On the other hand, regional hypertrophy (but not always muscle fascicle length) seems more important than changes in joint angle - specific neural drive for the joint angle - specific gains in strength after isometric training at long muscle lengths (Alegre et al. 2014; Noorkõiv et al. 2014).

This is because the changes in neural drive after explosive contraction and maximal (sustained) contraction strength training are very specific to the duration of the contraction performed (Tillin et al. 2012b; 2014; Balshaw et al. 2016).
