Is chronic pain a separate brain function? A new study maps the neurological loop between the spinal cord and cortex that drives persistent pain.

After my last Signal Chain Basics article, The basics of op amp loop-stability analysis: A tale of twin loop-gains, I received questions about how to generate the open-loop SPICE simulation curves ...

A series of recent studies in mice and rats has mapped specific brain circuits that appear to drive chronic pain, identifying ...

Some low-dropout regulators (LDOs) use multiple feedback loops to improve output voltage transient response. In many of these cases, some or all of the loops are inside the IC. Accessing these loops ...

A new map of a brain circuit specific to chronic pain suggests a promising route to treatment for the roughly 60 million Americans living with persistent pain, according to a study published in Nature ...
