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 ...

Tsukuba, Japan—Although we know that groups of cells working together in a specific brain region—the hippocampus—are vital for making, storing, and retrieving many types of memories, we still don't ...

Researchers have found that cells in the rat hippocampus -- a brain region that is essential for making memories -- are specifically organized into small clusters when fear-based memories are formed.
