How many years of memories 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.

What famous person has hyperthymesia?

actress Marilu Henner
The most famous is probably actress Marilu Henner, who showed off her stunning recall of autobiographical minutiae on “60 Minutes” a few years ago. What makes this condition, known as hyperthymesia, so fascinating is that it’s so selective.

How hyperthymesia affects the brain?

Short- and long-term memory are stored in different areas of the brain. People with HSAM process short-term memories the same way as most people do. But researchers have found that, unlike most people, the accuracy and detail of memories improve over time in people with HSAM.

Can you run out of brain space?

There is really no such thing as ‘a memory’. When our brains are overloaded the same neurones are used in multiple memories in very flexible ways. So we might become more likely to confuse events, or have other difficulties in remembering, but we can’t really say that we ‘run out of memory’.

What is the storage stage?

Storage is the second memory stage or process in which we maintain information over periods of time. Retrieval (or recall, or recognition): the calling back of stored information in response to some cue for use in a process or activity.

Does Marilu Henner have hyperthymesia?

Actress Marilu Henner says she can remember it all. The actress, who has also starred in “L.A. Story” (1991) and “Man on the Moon” (1999), is one of only 12 people in the world diagnosed with hyperthymesia, also known as Highly Superior Autobiographical Memory.

How do you test for hyperthymesia?

There is currently no way to diagnose hyperthymesia formally. Possible ways to assess this may be through MRI scans and complex memory tests. Hyperthymesia differs from eidetic memory in that it focuses on a person’s ability to recall their autobiographical experiences rather than to hold visualizations in their mind.

How common is hyperthymesia?

Hyperthymesia, or highly superior autobiographical memory (HSAM), is a condition that leads people to be able to remember an abnormally large number of their life experiences in vivid detail. It is extraordinarily rare, with only about 60 people in the world having been diagnosed with the condition as of 2021.

How much RAM is in the brain?

You might have only a few gigabytes of storage space, similar to the space in an iPod or a USB flash drive. Yet neurons combine so that each one helps with many memories at a time, exponentially increasing the brain’s memory storage capacity to something closer to around 2.5 petabytes (or a million gigabytes).
