We have demonstrated the operation of a chemical signal generator which can expose target cells to a stimulus chemical in a spatiotemporally varying manner via control of microfluidic channel inlet pressures.
can collaterals form de-novo? what is the primary growth stimulus: chemical (ischemia?) or physical?
During chemical stimulus presentations, chemical stimulus water was dripped into each test tank at constant rate; following chemical stimulus presentations, fry were removed from test tanks, the tanks were rinsed and then refilled with treated tap water, and fry pairs were returned to test tanks.
The appropriate stimuli (chemical, biological, mechanical and electrical) are applied and over a relatively short time new tissue is formed.
Intravital microscopy as a model for trigeminovascular nociception monitors dural vessel diameter in response to external stimuli, chemical or electrical, and relates the dilatory response to trigeminovascular activation.
Communication of sensory nerves responsive to noxious stimuli (chemical, mechanical, or inflammatory) with the central nervous system occurs via vagal, pelvic, and splanchnic nerve pathways [11, 12].
Physical stimuli, chemical feedback, and emotional impulses start battling it out in our heads even as we try to steer conversations with our kinda loved ones away from the subject of race.
In this experiment, we found that fry responded to predator visual stimuli, chemical stimuli, and a combination of visual and chemical stimuli with tighter shoaling behavior than when presented with stimuli from adult conspecifics (Figure 2).
Cerebral circulation is normally regulated by several complex mechanisms, such as metabolic stimuli, chemical stimuli, perfusion pressure, and neural stimuli [ 1].
Noxious stimuli (chemical, thermal or mechanical) activate nociceptors which are the peripheral endings of small diameter primary sensory neurons.
