Each time we revisit a memory, it becomes flexible again. The connections appear to become malleable, and then they reset.

Where are memories stored permanently?

An MIT study of the neural circuits that underlie memory process reveals, for the first time, that memories are formed simultaneously in the hippocampus and the long-term storage location in the brain's cortex.

How many years of memory can the brain hold?

A rough calculation by Paul Reber, Professor of Psychology at Northwestern University suggests that the brain can store 2.5 PETABYTES of data – that's 2,500,000 Gigabytes, or 300 years worth of TV.

How memories form and how we lose them - Catharine Young

How many GB is a human brain?

Is it possible to remember childhood memories?

But only in the past 10 years have scientific studies demonstrated a connection between childhood trauma and amnesia. Most scientists agree that memories from infancy and early childhood—under the age of two or three—are unlikely to be remembered.

What does childhood trauma look like in adults?

Childhood trauma also results in feeling disconnected, and being unable to relate to others. Studies have shown that adults that experience childhood trauma were more likely to struggle controlling emotions, and had heightened anxiety, depression, and anger.

Why am I suddenly remembering my childhood trauma?

Where does your mind go when you sleep?

REM sleep tends to combine increased energy provision to the brain and body, and so, this is generally when dreams occur. As the name suggests, during REM, your eyes move rapidly from side to side behind closed eyelids and brain wave activity becomes closer to that seen in wakefulness.
