Those circuits depend on enzymes known as recombinases, which can cut out stretches of DNA, flip them, or insert them. Sequential activation of those enzymes allows the circuits to count events ...

Memory formation and storage require long-lasting changes in memory-related neuronal circuits. Recent evidence indicates that DNA methylation may serve as a contributing mechanism in memory formation ...

One of the great puzzles of cell biology is how information is stored, processed and passed from generation to generation at the biochemical level. By far the most famous mechanism is the sequence of ...

Engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of ...

On theoretical grounds, the architecture of CA3 circuits seems to be well adapted for the rapid storage and retrieval of associative memories. This is thought to require plastic changes in the ...

Memory effects are ubiquitous in nature and the class of memory circuit elements – which includes memristors, memcapacitors and meminductors – shows great potential to understand and simulate the ...

Our brains do not react in a fixed, mechanical way like electronic circuits. Even if we see the same scene every day on our ...

Electromagnetic stimulation of an area of the brain known as the hippocampus has improved the memory of older adults with age-related memory loss, according to the results of a study published in the ...

Zebrafish, photographed with confocal microscope. The brain region that controls eye movement is structurally similar in fish and mammals, but the zebrafish system contains only 500 neurons, making it ...

The modern System-on-Chip (SoC) could reasonably be called an island of logic, surrounded by a sea of memory. The Semiconductor Industry Association (SIA) roadmap predicts that embedded memories will ...
