The raison d'etre of IR is to satisfy human information need. But, do we really understand information need? Despite advances in the past few decades in both the IR and relevant scientific communities, this question is largely unanswered. We do not really understand how an information need emerges and how it is physically manifested. Information need refers to a complex concept: at the very initial state of the phenomenon (i.e. at a visceral level), even the searcher may not be aware of its…

Neuropsychological Model of the Realisation of Information Need
TLDR
A neuropsychological model of the realisation of IN is proposed, consisting of a successful memory retrieval component, an information flow regulation component, and a high-level perception component that is based on a distributed set of brain regions associated with activities related to information need.
Neuropsychological model of the realization of information need
TLDR
Results of a functional connectivity analysis led to a neuropsychological model of the realization of IN, which consists of a successful memory retrieval component, an information flow regulation component, and a high‐level perception component.
Towards Predicting a Realisation of an Information Need based on Brain Signals
TLDR
This work has conducted experiments whereby twenty-four participants performed a Q/A Task, while their brain activity was being monitored using functional Magnetic Resonance Imaging (fMRI) technology, showing that monitoring brain activity can lead to accurate predictions of a realisation of an IN occurrence.
The Cortical Activity of Graded Relevance
TLDR
The findings show that significant differences in event-related potentials were observed in response to information segments processed in the context of high-relevance, low- relevance and no-relevant, supporting the concept of graded relevance.
NeuroIIR: Challenges in Bringing Neuroscience to Research in Human-Information Interaction
TLDR
The goal will be to clarify some of the major neurophysiological methodological concepts and constructs relevant to IR and IIR, expand awareness of critical parameters associated with neuro Physiological devices and equipment, and provide a foundation to researchers to enable them to apply appropriate neurophysiology modalities for specific types of IR andIIR research investigations.
Understanding Human Reading Comprehension with Brain Signals
TLDR
It is suggested that various cognitive activities, e.g., cognitive loading, semantic-thematic understanding, and inferential processing, at the micro-time scale during reading comprehension underpin these neural responses, which imply that brain signals are valuable feedback for enhancing human-computer interactions duringReading comprehension.
Cortical Activity of Relevance
TLDR
This work aims to focus on user relevance, which is characterised as a subjective process, dependant on the specific user mind state, that is based on mutual interaction of the system and user.
Search Process as Transitions Between Neural States
TLDR
This work directly monitors the brain activity of twenty-four participants during a search process that involved answering questions carefully selected from the TREC-8 and TREC 2001 Q/A Tracks to provide an important first step in representing the search process based on the transitions between neural states.
Neural Correlates of Realisation of Satisfaction in a Successful Search Process
In a search process, searchers review documents to gather information relevant to their information need (IN). During this process, searchers may experience the satisfaction of their IN, indicating…
The relationships between health information behavior and neural processing in african americans with prehypertension
TLDR
The findings suggest that neural processing of socially and emotionally salient health information is more closely associated with health information sharing than previously thought.

Understanding Relevance: An fMRI Study
TLDR
The results of this experiment revealed three brain regions in the frontal, parietal and temporal cortex where brain activity differed between processing relevant and non-relevant documents.
When Relevance Judgement is Happening?: An EEG-based Study
TLDR
Brain signals for the first 800 milliseconds of a relevance assessment process are analysed to answer the question "when relevance is happening in the brain?" with the belief that it will lead to better operational definitions of relevance.

The role of the posterior cingulate cortex in cognition and disease.
TLDR
A novel model of the posterior cingulate cortex's function is synthesized into a model that influences attentional focus by 'tuning' whole-brain metastability and so adjusts how stable brain network activity is over time, and is tested within the framework of complex dynamic systems theory.
Dynamic Neural Network of Insight: A Functional Magnetic Resonance Imaging Study on Solving Chinese ‘Chengyu’ Riddles
TLDR
This study supports the key role of hippocampus in forming novel associations, and indicates a dynamic neural network during insight solution, by using event-related functional magnetic resonance imaging during solving Chinese ‘chengyu’ riddles.
A default mode of brain function.
TLDR
A baseline state of the normal adult human brain in terms of the brain oxygen extraction fraction or OEF is identified, suggesting the existence of an organized, baseline default mode of brain function that is suspended during specific goal-directed behaviors.

Psychophysiological and Modulatory Interactions in Neuroimaging
TLDR
Interactions among extrastriate, inferotemporal, and posterior parietal regions during visual processing, under different attentional and perceptual conditions, are focused on.
What does the mediodorsal thalamus do?
TLDR
The evidence shows that the mediodorsal thalamus plays a critical role in many varied cognitive processes, and the MD is actively processing information and integrating it across these neural circuits for successful cognition.
