Anaphoric nouns are nouns which are used to refer back to some object or idea already presented in a text. They are usually very general words and often abstract nounsSee the glossary definition because they refer to ideas, arguments, theories and so on. When they are used to refer to ideas found elsewhere in a text they are sometimes known as shell nounsSee the glossary definition . They constitute an important class of words in academic discourseSee the glossary definition .
The text below contains examples of nouns used anaphorically to refer to previous items. It also contains other referenceSee the glossary definition items, some of which are highlighted and explained. The text is taken from an article, How memories are formed and retrieved by the brain revealed in a new study, in "The Conversation" by Benjamin J.

Undoubtedly, our ability to create and retrieve long-term memories is a fundamental part of the human experience – but we still have lots to learn about the process. For instance, we lack a clear understanding of how different brain regions interact in order to form and retrieve memories. But our recent study sheds new light on this phenomenon by showing how neural activity in two distinct brain regions interact during memory retrieval.
Try to remember that last dinner you went out for. Perhaps you can remember the taste of that delicious pasta, the sounds of the jazz pianist in the corner, or that boisterous laugh from the portly gentleman three tables over. What you probably can’t remember is putting any effort into remembering any of these little details.
Somehow, your brain has rapidly processed the experience and turned it into a robust, long-term memory without any serious effort from yourself. And, as you reflect on that meal today, your brain has generated a high-definition movie of the meal from memory, for your mental viewing pleasure, in a matter of seconds.
But the hippocampus is simply too small to store every little detail of a memory. This has lead researchers to theorise that the hippocampus calls upon the neocortex – a region which processes complex sensory details such as sound and sight – to help fill in the details of a memory.
"the process refers to the ability to create and retrieve long-tem memories. "process" is a noun which is often used anaphorically, compressing a concept which was explained in a longer stretch of text into one word.
The neocortex does this by doing the exact opposite of what the hippocampus does – it ensures that neurons do not fire together. This is often referred to as “neural desynchronisation”. Imagine asking an audience of 100 people for their names. If they synchronise their response (that is, they all scream out at the same time), you’re probably not going to understand anything. But if they desynchronise their response (that is, they take turns speaking their names), you’re probably going to gather a lot more information from them. The same is true for neocortical neurons – if they synchronise, they struggle to get their message across, but if they desynchronise, the information comes across easily.
Our research found that the hippocampus and neocortex do in fact work together when recalling a memory. This happens when the hippocampus synchronises its activity to glue parts of the memory together, and later help to recall the memory. Meanwhile, the neocortex desynchronises its activity to help process information about the event and later help process information about the memory.
"This" is simple pronoun reference and it refers to the whole of the previous sentence.
"The same” refers to the explanation in the previous sentence (in fact, it’s a substitution: it substitutes for the fact that if they synchronise their response, you’re not going to understand anything but if they desynchronise you’re going to gather a lot more information).
"phenomenon" is another noun often used to refer back to a complex process. In this case it refers to "how different brain regions interact in order to form and retrieve memories".
"experience" is a typical anaphoric noun. In this case it refers back to the whole event of the dinner (and the pasta, the jazz, the laugh) at the very beginning of the text.
"This happens" refers to the hippocampus and neocortex working together.
"This" is a simple pronoun reference but it refers to a complex procedure - glueing the parts of the memory together by making sure the "where" and the "when" neurons fire together. Luckily, it's in the previous sentence so it's easy to identify. We are also given a name for this procedure: "neural synchronisation". As a reader you should take note of this as it may be mentioned later in the text.
"does this" refers to the theory in the the previous paragraph - the theory that the neocortex helps to fill in the details of a memory.
"these little details" refers to taste of the delicious pasta, the sounds of the jazz pianist and the laugh from the portly gentleman. "details" is a noun often used to refer back (anaphorically) to particular items in a text.
"This" means ensuring that neurons do not fire together, at the end of the previous sentence.
small
"these details" refers to the neurons that code for the "where" and the "when”. As we’ve already seen, “details" is a noun often used to refer back to previously mentioned events or procedures.
The hippocampus, a structure located deep within the brain, has long been seen as a hub for memory. The hippocampus helps “glue” parts of the memory together (the “where” with the “when”) by ensuring that neurons fire together. This is often referred to as “neural synchronisation”. When the neurons that code for the “where” synchronise with the neurons that code for the “when”, these details become associated through a phenomenon known as “Hebbian learning”.
“the event” refers to "recalling a memory" in the first sentence. The word “event” is often used to refer to events or processes described earlier in a text.
But the hippocampus is simply too small to store every little detail of a memory. This has lead researchers to theorise that the hippocampus calls upon the neocortex – a region which processes complex sensory details such as sound and sight – to help fill in the details of a memory.

How memories are formed and retrieved by the brain revealed in a new study

Of cats and bicycles
We tested 12 epilepsy patients between 24 and 53 years of age. All had electrodes place directly within the brain tissue of their hippocampus and neocortex as part of the treatment for their epilepsy. During the experiment, patients learned associations between different stimuli (such as words, sounds and videos), and later recalled these associations. For example, a patient may be shown the word “cat” followed by a video of a bike cycling down a street.
The patient would then try and create a vivid link between the two (perhaps the cat riding the bike) to help them remember the association between the two items. Later, they would be presented with one of the items and asked to recall the other. The researchers then examined how the hippocampus interacted with the neocortex when the patients were learning and recalling these associations.
During learning, neural activity in the neocortex desynchronised and then, around 150 milliseconds later, neural activity in the hippocampus synchronised. Seemingly, information about the sensory details of the stimuli was first being processed by the neocortex, before being passed to the hippocampus to be glued together.
We found that the hippocampus and neocortex work closely together when forming and retrieving memories. Orawan Pattarawimonchai/ ShutterstockFascinatingly, this pattern reversed during retrieval – neural activity in the hippocampus first synchronised and then, around 250 milliseconds later, neural activity in the neocortex desynchronised. This time, it appeared that the hippocampus first recalled a gist of the memory and then began to ask the neocortex for the specifics.
Our findings support a recent theory which suggests that a desynchronised neocortex and synchronised hippocampus need to interact to form and recall memories.

While brain stimulation has become a promising method for boosting our cognitive facilities, it has proved difficult to stimulate the hippocampus to improve long-term memory. The key problem has been that the hippocampus is located deep within the brain and is difficult to reach with brain stimulation that is applied from the scalp. But the findings from this study present a new possibility. By stimulating the regions in the neocortex that communicate with the hippocampus, perhaps the hippocampus can be indirectly pushed to create new memories or recall old ones.
Understanding more about the way the hippocampus and neocortex work together when forming and recalling memories could be important for further developing new technologies that could help improve memory for those suffering from cognitive impairments such as dementia, as well as boosting memory in the population at large.
