Newborn girls prefer to look at faces while newborn boys prefer to look
at mechanical stimuli (such as mobiles).
The scientists discovered that a class of mechanoreceptors in the skin that detect
painful mechanical stimuli are part of a feedback circuit in which excitatory neurons that produce the hormone somatostatin are inhibited by neurons that synthesize dynorphin (a natural analgesic molecule that produces effects similar to opiates).
In vivo tracking of segmental bone defect healing reveals that callus patterning is related to
early mechanical stimuli.
Weight - bearing exercise in particular
provides mechanical stimuli or «loading» important for the maintenance and improvement of bone health, whereas physical inactivity has been implicated in loss of bone density.
In their recent publication in Science, the researchers demonstrate how bacteria recognize surfaces and respond to
this mechanical stimulus within seconds.
«However, we have little knowledge of how bacteria read out
mechanical stimuli and how they change their behavior in response to these cues,» says Jenal.
So ultimately
these mechanical stimuli determine how the plant embryo develops; but until now it wasn't possible to measure this,» says Sprakel.
«This work marks, to the best of our knowledge, the first identification of a genetic basis for a mast - cell - mediated urticaria induced by
a mechanical stimulus,» said Dean Metcalfe, M.D., chief of NIAID's Laboratory of Allergic Diseases and a study co-author.
The cell density of cartilage is also very low, therefore, cell cultures offer an easier approach to study cellular responses of chondrocytic cells, e.g., to
mechanical stimuli.
Researchers have identified a molecule that can transform
the mechanical stimulus of a sound wave into an electrical signal recognizable by the brain.
With the help of this channel,
the mechanical stimulus is transformed into electro - chemical activity.
Recent research has indicated that
the mechanical stimuli for hypertrophy and fiber type shifts are in fact different.
Mechanical stimuli, such as compression of the arterial muscle, induce arterial vasodilation, the magnitude of which is not affected by increasing the duration of compression, but it is enhanced by increasing the number of compressions (4).
