Abstract Background This study investigated the impact of semantic relevance on the ability to comprehend the appearance and function of a product, as presented in images. Methods The images used the constructs of Simile, Metaphor and Analogy to correspond to congruent, related and incongruent semantic structures, and measured the amplitude of Event-Related Potentials (ERPs) to compare these images with Landscape images. Sixteen participants with design-related educational backgrounds were invited to join in the ERP experiment. Results The results found that the image depicting the Metaphor showed a stronger N600 amplitude in the right anterior region of the brain than the Landscape image and the Analogy image induced a stronger N600 effect in the left anterior and right anterior part of the brain than the Landscape image. However, the Simile image did not trigger the N600. The N600 was triggered when the meaning of the Metaphor and Analogy being presented could not be understood. This indicates that a greater processing effort to comprehend them than was required for Simile. Analogy has a wider N600 distribution than Metaphor in the anterior area, suggesting that Analogy would require higher-level thinking processes and more complex semantic processing mechanisms than Metaphor. Conclusions The N600 implicated that an assessment method to detect the semantic relationship between appearance and function of a product would assist in determining whether a symbol was suitable to be associated with a product.

Purpose Improving the ability to listen efficiently in noisy environments is a critical goal for hearing rehabilitation. However, understanding of the impact of difficult listening conditions on language processing is limited. The current study evaluated the neural processes underlying semantics in challenging listening conditions. Method Thirty adults with normal hearing completed an auditory sentence processing task in 4-talker babble. Event-related brain potentials were elicited by the final word in high- or low-context sentences, where the final word was either highly expected or not expected, followed by a 4-alternative forced-choice response with either longer (1,000 ms), middle (700 ms), or shorter (400 ms) response time deadlines (RTDs). Results Behavioral accuracy was reduced, and reactions times were faster for shorter RTDs. N400 amplitudes, reflecting ease of lexical access, were larger when elicited by target words in low-context sentences followed by shorter compared with longer RTDs. Conclusions These results reveal that more neural resources are allocated for semantic processing/lexical access when listening difficulty increases. Differences between RTDs may reflect increased attentional allocation for shorter RTDs. These findings suggest that situational listening demands can impact the demands for cognitive resources engaged in language processing, which could significantly impact listener experiences across environments.

Background. Alexander Romanovich Luria (1902–1977) is a widely recognized authority, attributed with the birth and development of neuropsychology. Reading the list of Luria’s publications makes us aware of the wide range of his interests: from the brain location of mental functions, through methods of rehabilitation and education, cognitive processing, issues of language, intellectual development or the impact of culture on human development, to intercultural research, and consequently to the neuropsychology of creativity. The purpose of this article is to show the link between Luria’s approach and the neuropsychology of creativity, and to demonstrate that a process thinking, taking into account brain/mind state, offers a new way of conceptualizing different approaches to creativity, which can be a step toward their unification, bringing into relation the continuum of passage in nature to a transition from repetition to innovation to genius. Objective. The aim of the present paper is to present the brain mechanisms of creativity. It discusses the neuropsychology of creativity as a subdiscipline developing on the borderline of: (1) medical neuroscience — using clinical and experimental neuroanatomical, neurophysiological, neurobiological, neurosurgical, neurological, neuropsychiatric and (2) social neuroscience — using social psychology and neuropsychology, social linguistics and neurocultural studies to help disabled people. Special focus is placed on the functioning of artists with various forms of brain damage. The relationships between brain damage and the quality of creation are also discussed. In addition, a review of opinions of various authors from around the world on the relationship of the healthy and the damaged brain with creativity is presented in the paper. Case study. Described also are ways to avoid pitfalls in the interpretation of works of art taking into account Luria’s syndrom analysis. While studying the neurological and neuropsychiatric basis of the creativity of people with various brain injuries, one should take into account the possibility of the co-occurrence of syndromes as well as the overlapping of symptoms. The paper presents a case history of the illness of an artist that illustrates the importance of performing a syndrome analysis based on the Lurian approach. It also indicates the significance of supporting any neuropsychological assessment with the use of neuromarkers to avoid arriving at a false diagnosis. In the case of the patient described neurophysiological studies (neuroimaging studies of the brain, quantitative electroencephalography (qEEG), event-related potentials (ERPs) and standardized Low Resolution Electromagnetic Tomography (sLORETA) have proved to be very useful in the confirmation of his neuropsychological and neuropsychiatric diagnosis. Conclusions. The paper has presented data confirming the importance of Luria’s approach in the development of the neuropsychology of creativity. It was also an attempt to explain why we create, and what goes on in our bodies and minds when we begin to explore creative possibilities. Art in all of its manifestations (visual art, music, literature, dance, theater, and more) is an important feature of human societies in both norm and pathology, and therefore deserves further study.

Recent neuroimaging and electrophysiological studies reveal how the reading system successfully adapts when phonological codes are relatively coarse-grained due to reduced auditory input during development. New evidence suggests that the optimal end-state for the reading system may differ for deaf versus hearing adults and indicates that certain neural patterns that are maladaptive for hearing readers may be beneficial for deaf readers. This chapter focuses on deaf adults who are signers and have achieved reading success. Although the left-hemisphere-dominant reading circuit is largely similar in both deaf and hearing individuals, skilled deaf readers exhibit a more bilateral neural response to written words and sentences than their hearing peers, as measured by event-related potentials and functional magnetic resonance imaging. Skilled deaf readers may also rely more on neural regions involved in semantic processing than hearing readers do. Overall, emerging evidence indicates that the neural markers for reading skill may differ for deaf and hearing adults.

This article suggests that the potential usefulness of event-related potentials in psychiatry has not been fully explored because of the limitations of various approaches to research adopted to date, and because the field is still undergoing rapid development. Newer approaches to data acquisition and methods of analysis, combined with closer co-operation between medical and physical scientists, will help to establish the practical application of these signals in psychiatric disorders and assist our understanding of psychophysiological information processing in the brain. Finally, it is suggested that psychiatrists should seek to understand these techniques and the data they generate, since they provide more direct access to measures of complex cerebral processes than current clinical methods.

The main goal of this event-related potentials (ERPs) study was to assess the effects of stimulations in Stroop task in brain activities of patients with different degrees of depression. Eighteen patients (10 males, with the mean age [Formula: see text]) were asked to fill out Beck’s depression questionnaire. Electroencephalographic (EEG) signals of subjects were recorded in three channels (Pz, Cz, and Fz) during Stroop test. This test entailed 360 stimulations, which included 120 congruent, 120 incongruent, and 120 neutral stimulations. To analyze the data, 18 time features in each type of stimulus were extracted from the ERP components and the optimal features were selected. The correlation between the subjects’ scores in Beck’s depression questionnaires and the extracted time features in each recording channel was calculated in order to select the best features. Total area, and peak-to-peak time window in the Cz channel in both the congruent and incongruent stimulus showed significant correlation with Beck scores, with [Formula: see text], [Formula: see text] and [Formula: see text], [Formula: see text], respectively. Consequently, given the correlation between time features and the subjects’ Beck scores with different degrees of depression, it can be interpreted that in case of growth in degrees of depression, stimulations involving congruent images would produce more challenging interferences for the patients compared to incongruent stimulations which can be more effective in diagnosing the level of disorder.

Migraine attacks can cause significant discomfort and reduced functioning for days at a time, including the pre-ictal and post-ictal periods. During the inter-ictsal period, however, migraineurs seem to function normally. It is puzzling, therefore, that event-related potentials of migraine patients often differ in the asymptomatic and inter-ictal period. Part of the electrophysiological dynamics demonstrated in the migraine cycle are attention related. In this pilot study we evaluated an easy-to-use new marker, the Brain Engagement Index (BEI), for attention monitoring during the migraine cycle. We sampled 12 migraine patients for 20 days within one calendar month. Each session consisted of subjects’ reports of stress level and migraine-related symptoms, and a 5 min EEG recording, with a 2-electrode EEG device, during an auditory oddball task. The first minute of the EEG sample was analyzed. Repetitive samples were also obtained from 10 healthy controls. The brain engagement index increased significantly during the pre-ictal (p ≈ 0.001) and the ictal (p ≈ 0.020) periods compared with the inter-ictal period. No difference was observed between the pre-ictal and ictal periods. Control subjects demonstrated intermediate Brain Engagement Index values, that is, higher than inter-ictal, yet lower than pre-ictal. Our preliminary results demonstrate the potential advantage of the use of a simple EEG system for improved prediction of migraine attacks. Further study is required to evaluate the efficacy of the Brain Engagement Index in monitoring the migraine cycle and the possible effects of interventions.
