Human working memory is based on dynamic interaction networks in the brain. A research project of the Neuroscience Center of the University of Helsinki sheds light on the neuronal mechanisms sustaining memory traces of visual stimuli in the human brain. The results show that the maintenance of working memory is associated with synchronisation of neurons, which facilitates communication between different parts of the brain. On the basis of interaction between the brain areas, it was even possible to predict the subject's individual working memory capacity. The results were published last week in the online version of the journal PNAS. The working memory of an average person can sustain only three of four objects at a time. Maintaining of a memory trace synchronised different brain areas In their study, the researchers mapped almost four billion different neuronal interactions.
The study also revealed several specialized function-specific networks and interactions between them. Robust Short-Term Memory without Synaptic Learning.

How to Memorize Things Quickly. People like to joke that the only thing you really “learn” in school is how to memorize. As it turns out, that’s not even the case for most of us. If you go around the room and ask a handful of people how to memorize things quickly, most of them will probably tell you repetition. That is so far from the truth, it’s running for office. If you want to memorize something quickly and thoroughly, repetition won’t cut it; however, recalling something will. The problem is that recalling something requires learning, and we all learn in different ways.
Below are some universal steps to mastering the art of recalling so that you can start memorizing a ton of data in a short amount of time. Before we start, you need to establish something: are you an auditory, visual, or experiential learner? Step 1: Preparation To optimize your memorization session, pay close attention to which environment you choose. Next, start drinking some tea. Step 2: Record What You’re Memorizing Step 3: Write Everything Down. Paired Associates Memory Assessment - Cambridge Brain Sciences. In this task you have to remember which objects are hidden in different boxes. Psychologists call the skills required for this task 'paired-associate-learning', as you are required to learn to pair two items in memory - in this case the type of object and the location of the object.
When one of the paired features is revealed (in this case the object), you have to remember its associate (the location it is hidden in). This type of learning is essential in everyday life, for example when learning new words. When you learn a new word, not only do you learn the word itself, but you have to pair this with the meaning it represents. Along with our colleagues at the University of Cambridge and at the Institute of Psychiatry in London, we investigated which areas of the brain become active when performing this task. Furthermore, we studied what happens to this activation pattern when the task gets harder and harder. References Gould, R.L., Brown, R.G., Owen, A.
