How Does Memory Work in the Brain?

People have various descriptions of memory. Experts liken it to a hard drive where we encode, store, and retrieve information. Now, they see it as a multidimensional process.

When we try to perform an activity such as preparing a particular dish, we easily recall the series of steps involved in cooking process as well as the cooking safety that must be observed. This is because memory does not involve one specific brain part alone but many parts of a whole.

The human brain functions using three basic cognitive processes. Storing memory into the brain all starts with encoding. This is the stage where the brain records information based on what is seen, heard, and felt by an individual. The receptors are then activated by neurotransmitters that signal the brain to react to the stimuli.

Next, our brain stores the information. This stage also has an effect on how long the brain can hold on to a memory and the brain capacity can keep numerous memories in reserve. Long-term Potentiation is responsible for the tenacity in the connection of brain cells so when the strength is preserved, memory is created. How we save information in our brain will have an impact on how we will retrieve that information in the future.

The last step is the retrieval process which involves accessing the information that was stored. We easily remember things depending on the strength of the network system of synaptic contacts.

Although experts who conducted studies on the cerebrovascular system say that there is a connection between memory and judgment, how the brain operates still remains to be a mystery that needs to be unveiled. More research still needs to be done by these experts to better understand fully how the human brain produces memory and how memory can be affected by multiple factors.
