Sharp drop in stress hormones may set stage for arthritis, multiple sclerosis after pregnancy
... "fight or flight" response, in which strength and reflexes
are enhanced, to escape or deal with a possible threat. Other research has shown that all three of these stress hormones serve to hinder the production of immune system hormones. The increase in these stress hormones is probably caused by the maste...
Cell transplants look promising for stroke recovery
... on their motor and sensory abilities and on their reflexes
before the stroke and at one day, seven days and 14 days after the stroke. In a test of sensory abilities 14 days after the stroke, the rats treated with marrow stromal cells completed the test 60 percent faster than the non-treated rats. A detailed ...

...pical anesthetic in the upper airway removed local reflexes
that promote airway patency (openness) during wakefulness. From their tests, the researchers discovered that the children's airways were smaller in sleep-disordered breathing patients, and that upper airway collapsibility and sleep-disordered breath...
SIDS risk linked to lack of experience with tummy-sleeping
...ds to breathe easier. If so, is that because their reflexes
haven't developed far enough or because they just don't wake up?" Thach and his colleagues studied 38 healthy infants aged 3 to 37 weeks. Half of the babies usually slept prone or had a history of turning prone during sleep. The other babies had neve...
Rat whisking may provide insight into debilitating eye disorder
...ink circuit." The only neural circuits controlling reflexes
that had been identified prior to the UCSD physicists' discovery were negative feedback loops, in which sensory input leads to motor output that withdraws sensors from the source of a stimulus. For example, such a reflex occurs if you accidentally t...
