In a fruit fly, nerve cells that detect limb movement are silenced when the insect walks or grooms. This on-off switch may help the nervous system to shift between two states: one helps keep the body ...

LET us revert now to the reflex “standing” exhibited by the decerebrate animal. We traced it to a postural contraction of the antigravity muscles, in each of which the contraction was due to a ...

Orthostatic hypertension—a rise in blood pressure upon assuming upright posture—is an underappreciated and understudied clinical phenomenon. There is currently no widely agreed-upon definition of ...

A nervous system circuit in fruit flies toggles between supporting stabilizing body posture reflexes or dynamic voluntary action like walking. In a fruit fly, nerve cells that detect limb movement are ...

When each of us sits down, we navigate our feet to a position that feels comfortable, even if the seat we are in is uncomfortable. What we may not realize is that how we position our feet may affect ...
