A player's brain function changed more as their number of hits increased.
- The results confirm the growing theory that a concussion results from a series of blows, not simply one big impact.
- Specialized helmets with sensors were worn by the athletes, who could count and assess the force of head strikes. The kids underwent a test of thinking and memory while the players were placed in an MRI scanner to measure their brain activity.
- The brain scans and the hits were then compared. Those were common hits.
- The quantity and distribution of hits were connected to the changes in brain function that were observed over time in the MRIs. Brain activity did vary, but mental performance did not.
- The brain may be employing other areas to replace those impacted by the blows in order to get around those alterations.
Therefore, a player hit several times has more chances of concussion.

Answer:
After a good meal, Jane is relaxing comfortably as her food digests, suggesting her <u>parasympathetic</u> nervous system is in control. When she is frightened by a loud noise, Jane's digestion is inhibited and her heartbeat accelerates, suggesting her<u> sympathetic </u>nervous system is in control.
Explanation:
Parasympathetic nervous system and the sympathetic nervous system are two of the 3 domains of the autonomic nervous system.
During the resting and the relaxing stage,<u> parasympathetic system</u> (also called as rest or digest system) is activated which is associated with the conservation of the energy by :
1) Slowing the heart rate
2) Increasing the intestinal activity ( the reason why Jane is relaxing comfortably as her food digests )
3) Relaxation of the sphincter muscles of the GIT.
While during the fight , flight or fright stage , the <u>sympathetic nervous system</u> is activated which is associated with the body alertness by :
1) Increasing the heart rate
2) Inhibition of secretion of GIT enzymes ( the reason why digestion of JANE is inhibited )
3) Relaxation of the walls and the contraction of the sphincters of the GIT smooth muscle.
