How does memory actually work?

In light of current research in cognitive science, the very, very short answer to these questions is that memory operates according to a “dual-process,” where more unconscious, more routine thought processes (known as “System 1”) interact with more conscious, more problem-based thought processes (known as “System 2”).

How is memory stored in the brain?

Researchers have been able to trace memory down to the structural and even the molecular level in recent years, showing that memories are stored throughout many brain structures in the connections between neurons, and can even depend on a single molecule for their long-term stability.

Which brain is responsible for memory?

Hippocampus
Hippocampus. A curved seahorse-shaped organ on the underside of each temporal lobe, the hippocampus is part of a larger structure called the hippocampal formation. It supports memory, learning, navigation and perception of space.

How is a memory made?

The brain simmers with activity. Different groups of neurons (nerve cells), responsible for different thoughts or perceptions, drift in and out of action. Memory is the reactivation of a specific group of neurons, formed from persistent changes in the strength of connections between neurons.

How memory is formed?

How many years of memory can the brain hold?

300 years
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 are 3 ways we forget?

There are three ways in which you can forget information in the STM:

  • Decay. This occurs when you do not ‘rehearse’ information, ie you don’t contemplate it.
  • Displacement. Displacement is quite literally a form of forgetting when new memories replace old ones.
  • Interference.

How can we improve memory?
