Function of hippocampus in “insight” of problem solving

  title={Function of hippocampus in “insight” of problem solving},
  author={Jing Luo and Kazuhisa Niki},
Since the work of Wolfgang Köhler, the process of “insight” in problem solving has been the subject of considerable investigation. Yet, the neural correlates of “insight” remain unknown. Theoretically, “insight” means the reorientation of one's thinking, including breaking of the unwarranted “fixation” and forming of novel, task‐related associations among the old nodes of concepts or cognitive skills. Processes closely related to these aspects have been implicated in the hippocampus. In this… 

New advances in the neural correlates of insight: A decade in review of the insightful brain

The first neuroimaging study of real-time brain activity during insight problem solving was conducted almost ten years ago. Many subsequent studies have used high-resolution event-related potentials

Neural correlates of insight phenomena

Difficult problems are sometimes solved in a sudden flash of illumination, a phenomenon referred to as “insight.” Recent neuroimaging studies have begun to reveal the neural correlates of the

Medial temporal lobe amnesia impairs performance on a free association task

The results support the prediction that the hippocampus contributes to free association, and possibly more generally to other generative tasks that are open‐ended, creative, or that elicit the use of contextual and likely episodic memories in order to derive relevant information.

Learning by Insight-Like Sudden Comprehension as a Potential Strategy to Improve Memory Encoding in Older Adults

Overall memory performance was better in young participants but older participants exhibited a stronger beneficial effect of insight-like sudden comprehension on later recognition memory for CRA items, suggesting that learning via insight might constitute a promising approach to improve memory function in old age.

On the “Demystification” of Insight: A Critique of Neuroimaging Studies of Insight

Psychologists studying problem solving have, for over 100 years, been interested in the question of whether there are two different modes of solving problems. One mode—problem solving based on

Neural Correlates of Learning from Induced Insight: A Case for Reward-Based Episodic Encoding

It is proposed that learning from induced insight mainly relies on the amygdala evaluating the internal value of the suddenly comprehended information, and striatum-dependent reward-based learning.

Altered Brain Connectivity Patterns of Individual Differences in Insightful Problem Solving

Insightful problem solving (IPS) attracts widespread attention in creative thinking domains. However, the neural underpinnings of individual differences in IPS are still unclear. The purpose of this



Hippocampal system and declarative (relational) memory: Summarizing the data from functional neuroimaging studies

The relational (declarative) memory account, in which it is proposed that the hippocampal system plays a critical role in binding together multiple inputs to permit representations of the relations among the constituent elements of scenes or events, can better accomodate the full range of imaging data than any other explanatory account of hippocampal function.

Key hypotheses are that the CA3 pyramidal cells operate as a single autoassociation network to store new episodic information as it arrives via a number of specialized preprocessing stages from many different association areas of the cerebral cortex, and that the dentate granule cell/mossy fiber system is important particularly during learning to help to produce a new pattern of firing in theCA3 cells for each episode.

Hippocampal conjunctive encoding, storage, and recall: Avoiding a trade‐off

This analysis is focused on the feedforward pathways from the entorhinal cortex to the dentate gyrus (DG) and region CA3 and finds that Hebbian synaptic modification facilitates completion but reduces separation, unless the strengths of synapses from inactive presynaptic units to active postsynaptic units are reduced (LTD).

Role of medial temporal lobe in extensive retrieval of task‐related knowledge

The results of event‐related fMRI analysis indicated that MTL was more activated in the retrieval of old semantic associations than in the establishment of new semantic associations.

The role of the anterior prefrontal cortex in human cognition

The results indicate that the fronto-polar prefrontal cortex selectively mediates the human ability to hold in mind goals while exploring and processing secondary goals, a process generally required in planning and reasoning.

Verbal novelty detection within the human hippocampus proper.

It can be concluded that the human hippocampus proper contributes to verbal novelty detection because sclerosis of the hippocampus proper selectively reduced event-related potentials to new but not old verbal stimuli.

Contribution of human hippocampal region to novelty detection

THE ability to respond to unexpected stimuli (the 'orienting response') is a fundamental characteristic of mammalian behaviour1, but the brain mechanisms by which novelty is detected remain poorly
