Malfunctioning gene associated with Lou Gehrig’s disease leads to nerve-cell death in mice

PHILADELPHIA — Lou Gehrig’s disease, or amyotrophic lateral sclerosis (ALS), and frontotemporal lobar degeneration (FTLD) are characterized by protein clumps in brain and spinal-cord cells that include an RNA-binding protein called TDP-43. This …

Neural biology explains ejaculation

How does the body know it has had an ejaculation? And why does it care? Anatomically, it is more complex than it seems, says the University of Cincinnati scientist who last year identified the spinal cord cells that control ejaculation in rats and the neural pathway by which signals travel between the body’s sexual organs to the brain.
