Reactivating memories during sleep: Memory rehearsal during sleep can make a big difference in remembering later
Why do some memories last a lifetime while others disappear quickly? A new study suggests that memories rehearsed, during either sleep or waking, can have an impact on memory consolidation and on what is remembered ...

After 100 years, understanding the electrical role of dendritic spines
It's the least understood organ in the human body: the brain, a massive network of electrically excitable neurons, all communicating with one another via receptors on their tree-like dendrites. Somehow these ...

How connections in the brain must change to form memories could help to develop artificial cognitive computers
Exactly how memories are stored and accessed in the brain is unclear. Neuroscientists, however, do know that a primitive structure buried in the center of the brain, called the hippocampus, is a pivotal region ...

Stress breaks loops that hold short-term memory together: study
Stress has long been pegged as the enemy of attention, disrupting focus and doing substantial damage to working memory—the short-term juggling of information that allows us to do all the little things that make us productive.

Computer memory
Computer memory refers to devices that are used to store data or programs (sequences of instructions) on a temporary or permanent basis for use in an electronic digital computer. Computers represent information in binary code, written as sequences of 0s and 1s. Each binary digit (or "bit") may be stored by any physical system that can be in either of two stable states, to represent 0 and 1. Such a system is called bistable. This could be an on-off switch, an electrical capacitor that can store or lose a charge, a magnet with its polarity up or down, or a surface that can have a pit or not. Today capacitors and transistors, functioning as tiny electrical switches, are used for temporary storage, and either disks or tape with a magnetic coating, or plastic discs with patterns of pits are used for long-term storage.
Computer memory is usually meant to refer to the semiconductor technology that is used to store information in electronic devices. Current primary computer memory makes use of integrated circuits consisting of silicon-based transistors. There are two main types of memory: Volatile and Non-volatile.
