Memory involves the whole body. It’s how the self defies amnesia | Psyche Ideas
Forming New Memories
Our consciousness is deeply connected to our thinking and memory, and self-remembrance is an automatic feature of our brain.
People who have survived accidents or illness which limit their brain functioning, making them unable to form any new memory, question the presumption we have of our minds being our sole repository of identity.

Where your brain keeps memories
By studying people with amnesia, it seems that short-term and long-term memories don't form in precisely the same way, nor do declarative and procedural memories.
- Emotional responses such as fear occur in a brain region called the amygdala.
- Memories of learned skills are associated with the region called the striatum.
- The hippocampus is essential for forming, retaining, and recalling declarative memories.
- The temporal lobes play a critical role in forming and recalling memories.
How we experience memories
Memories are held within groups of neurons called cell assemblies. They fire as a group in response to a specific stimulus, such as recognising your friend's face.
The more neurons fire together, the more the interconnection of the cells strengthen. We experience the nerves' collective activity as a memory.

Memorizing new material
When we try to memorize new information, we assume that the more work we put in, the better we will do.
But, our memory for new information is the most fragile just after it has first been en...
Take some downtime
Aiming for minimal interference - to do literally nothing - is the best way to consolidate the facts and remember it better.
Research found that short periods of rest increased the ability to recall information up to 30 % in healthy individuals. For people with neurological injury, such as a stroke, the ability to recall after some rest, places them almost within the range of healthy people.
We remember better after rest
When memories are initially encoded, they pass through a period of consolidation that cements them in long-term storage.
It was once thought to happen mostly during sleep; studies have found that it is not limited to sleep, because it happens during periods of wakeful rest, too.

Memory Distortion
We all can form complex false memories in us, and it can even impact our decision making and future behavior. Planting false memories in a person can be used to tackle certain disorders like obesity and alcoholism.
Memory researchers have concluded that it is possible to induce fictional memories of the past in volunteers and even make them believe in some past criminal deeds that never happened.
False Memories: Legal Issues
False memories are a challenge in legal cases, as they are indistinguishable from real memories, with any distortion being undetectable.
Certain regression therapies where patients confront their buried childhood memories are prone to ‘implantation’ of false memories in their minds.
