Analog vs. Digital: What’s the Difference? Air temperature, sound loudness,light intensity—in nature, all of these quantities vary smoothly and continuously over a range. Such quantities is called ...

With transistors and logic gates as our basic building blocks, we can begin to construct the actual circuits that make up computer memory. One of the simplest memory circuits is the AND gate, which ...

Using a sophisticated brain-imaging system, neuroscientists say they have successfully reactivated a specific memory circuit in mice, causing them to seek out shelter when no shelter is actually ...

Virginia Tech researchers are investigating how overloaded mitochondria in the brain’s memory circuits may spark early Alzheimer’s damage. Their work focuses on calcium signaling and how it might ...
