Why Homeodynamics, Not Homeostasis?

Homeodynamics versus homeostasis: periodicities superimposed on non-linear dynamic sympathetic tone generated in ventral medulla.

Homeodynamics based on theories of complexity and chaos and its impact on mechanisms generating sympathetic activity are presented. Activity in rats cervical, lumbar and renal sympathetic nerves was analyzed. In time domain glutamate stimulation of neurons within medullary periambigual area (PAA) disturbed temporal pattern of respiratory-sympathetic synchronization. Divalént calcium antagonists...

Why does the central nervous system not regenerate after injury?

A major problem for neuroscientists and clinicians is why the central nervous system shows ineffective regeneration after injury. Injured peripheral nerve fibers reform their connections, whereas those in injured spinal cord never re-grow. Insights into the mechanisms for repair and restoration of function after spinal cord injury have been obtained by experiments showing that injured nerve cel...

Why not?

We study the ”Left handed Octopus” problem. In general, we do very strange things that may imply that we are not all together well in our heads.

Why Not?
