Opis:: This review contains a search for neuropragmatic studies related to the perlocutionary effects of speech acts on linguistic representations in the brain. This review study investigates the use of the electroencephalograph (EEG) with the event-related potentials (ERP) approach (method). This search was carried out by applying a number of criteria to the selection of articles using several search keywords, especially those related to the perlocutionary effects of speech acts and EEG/ERP. Of the 1,737 articles, 30 of them met the predetermined criteria. The results of this review are that there are three focuses of EEG/ERP-based neuropragmatic studies related to (1) the effect of stimulation of short sentences/speech in the context of conversation; (2) the effect of stimulation of literal and non-literal speech acts (irony and metaphor), and (3) the effect of stimulation of continuous speech acts in the context of discourse.

Opis:: The results of contemporary studies confirm the formation of two neural networks in the brain during the period of adolescence. The first is defined as emotional, located in the limbic system, develops earlier, quicker, and more intensively than the second one in the prefrontal cortex, called the judgement network, which fulfils the role of control and inhibition of emotional reactions. The domination of the emotional network in adolescence is manifested by hyperactivity of the limbic system, accompanied by intensified undertaking of courageous, reckless, risky, or even sometimes dangerous actions, so very characteristic in the maturation. The aim of the article is to present the state of the art in the field of latest achievements in experimental neurophysiology related to the maturation of the structural end functional processes in adolescents, and to alcohol vulnerability. Alcohol effect initiation starts in early adolescence, and therefore is connected with alcohol abuse and addiction in adulthood, which confirms the necessity for provision of an early prophylactic protection for juveniles, even before entering the phase of early adolescence. Some electrophysiological characteristics, such as low P3 amplitude of the Event-Related Potential (ERP) and Event-Related Oscillations (EROs), are manifested by their high risk offspring, and are considered to be biological markers (endophenotypes) of a predisposition to develop alcohol use disorders. Electroencephalographic oscillations induced within the range of the theta and delta waves (Event-Related Oscillation- ERO), considered as endophenotypes and markers of increased vulnerability for addiction, present three groups of genes and three types of neurotransmitters, with gamma aminobutyric acid, acetylcholine and glutamate as neurotransmitters in the central nervous system. A new research approach consisting in the application of electroencephalographic methods and techniques in developmental and genetic studies of the conditioning of varied vulnerability, and especially increased preferences for alcohol tasting and abuse in adolescence, provide unique possibilities for comprehensive and deepened studies which may contribute to the prevention of alcohol addiction, the genesis of which, to a great extent, is related with the effect of causative environmental and genetic factors during adolescent development.

Opis:: This paper presents an objective method for early diagnosis of disorders and diseases of olfactory system. To achieve this goal the author designed a fragrance dosing prototype, which is synchronized with the dedicated recorder of olfactory evoked potentials. Automatic synchronization of registration of olfactory event-related potentials with dosing of stimulus fragrances enables precise determination of latency occurring between stimulation and response of the central nervous system. Obtained results allow to prove that developed prototype enables the evaluation of the olfactory system disorders in the context of neurodegenerative disorders. However it is necessary to establish a standardization procedures, before a wide implementation in a clinical practice. That is why the developed method requires a broader research which is an issue of a much larger group of patients and significantly longer duration of the study.
