Explore your Memories
But every end we pull on winds up tugging on a handful of others. Next, Ramirez is investigating what happens when instead of chronically activating a negative memory, you turn up the volume on a positive one. Could you, for instance, turn a negative memory into a positive one by artificially boosting the good-feeling brain centers while someone is recalling something traumatic?
Could you use that to treat PTSD? Ramirez hopes to bring some rigorous science to the somewhat squishy study of positive thinking, to map how it remodels the brain, possibly protecting against aging and injury. Neuroscientist and public science communicator Anil Seth uses the power of Twitter to answer some common questions about neuroscience.
How Memory Works
How does memory work? Can we delete memories? Do blind people dream? Anil answers all these questions and more! Using mice whose neurons had been engineered to respond to light, researchers found they could dial up or down the emotional intensity of a memory. Getty Images.

Memory is the term given to the structures and processes involved in the storage and subsequent retrieval of information. Memory is essential to all our lives. Without a memory of the past, we cannot operate in the present or think about the future. We would not be able to remember what we did yesterday, what we have done today or what we plan to do tomorrow.
Without memory, we could not learn anything. Memory is involved in processing vast amounts of information. This information takes many different forms, e. When information comes into our memory system from sensory input , it needs to be changed into a form that the system can cope with, so that it can be stored. Think of this as similar to changing your money into a different currency when you travel from one country to another.
For example, a word which is seen in a book may be stored if it is changed encoded into a sound or a meaning i.

For example, how do you remember a telephone number you have looked up in the phone book? If you can see it then you are using visual coding, but if you are repeating it to yourself you are using acoustic coding by sound. Evidence suggests that this is the principle coding system in short-term memory STM is acoustic coding. When a person is presented with a list of numbers and letters, they will try to hold them in STM by rehearsing them verbally.
Rehearsal is a verbal process regardless of whether the list of items is presented acoustically someone reads them out , or visually on a sheet of paper. The principle encoding system in long-term memory LTM appears to be semantic coding by meaning. However, information in LTM can also be coded both visually and acoustically. This concerns the nature of memory stores, i.
The way we store information affects the way we retrieve it. Most adults can store between 5 and 9 items in their short-term memory. Miller put this idea forward and he called it the magic number 7. In contrast, the capacity of LTM is thought to be unlimited. This refers to getting information out storage.

STM is stored and retrieved sequentially. For example, if a group of participants are given a list of words to remember, and then asked to recall the fourth word on the list, participants go through the list in the order they heard it in order to retrieve the information. LTM is stored and retrieved by association. This is why you can remember what you went upstairs for if you go back to the room where you first thought about it. Organizing information can help aid retrieval.
What we do
You can organize information in sequences such as alphabetically, by size or by time. Imagine a patient being discharged from hospital whose treatment involved taking various pills at various times, changing their dressing and doing exercises. If the doctor gives these instructions in the order which they must be carried out throughout the day i.
