Effects of assisted training with neurofeedback on EEG measures, executive function and mood in a healthy sample

2015

The training in neurofeedback (NF) consists of teaching individuals to modify, adjust and enhance their brain activity pattern. The aim of our research was to evaluate the effect of training on cognitive processes, specifically executive function, and mood in a non-clinical sample. A sample of 30 female college students were assigned to three groups: RH: right hemisphere (n = 10), LH: left hemisphere (n = 10) and control (n = 10). The dominance pattern of beta and the inhibition of the theta pattern were trained in a single session. Measures of executive function (Iowa Gambling Test) and questionnaires of mood were taken pre and post training. We found that NF training produced significant …

El trastorno de Tourette es el resultado de una disfuncion cerebral frontoestriatal que afecta a personas de todas las edades, con un inicio en la primera infancia y continuacion en la adolescencia y la adultez. Desarrollo. Este articulo revisa los principales aspectos cognitivos, de neuroimagen funcional y estudios relacionados con la creatividad en un trastorno caracterizado por un exceso de dopamina en el cerebro. Conclusiones. Dada la especial configuracion cerebral de estos pacientes, deberian esperarse alteraciones neuropsicologicas, especialmente en las funciones ejecutivas. Sin embargo, los hallazgos son poco concluyentes y estan condicionados por factores como la como…

Deceit and facial expression in children: the enabling role of the “poker face” child and the dependent personality of the detector

2015

This study presents the relation between the facial expression of a group of children when they told a lie and the accuracy in detecting the lie by a sample of adults. To evaluate the intensity and type of emotional content of the children’s faces, we applied an automated method capable of analyzing the facial information from the video recordings (FaceReader 5.0 software). The program classified videos as showing a neutral facial expression or an emotional one. There was a significant higher mean of hits for the emotional than for the neutral videos, and a significant negative correlation between the intensity of the neutral expression and the number of hits from the detectors. The lies ex…

Drogas legales emergentes: marihuana sintética, kratom, salvia divinorum, metoxetamina y los derivados de la piperazina

2015

A pesar de su amplia oferta y disponibilidad a través de internet, muchas de las drogas de abuso emergentes siguen siendo desconocidas para un gran número de médicos y profesionales sanitarios. Las alternativas herbales a la marihuana (también conocidas como marihuana sintética), tales como el K2 o el spice, son un grupo de hierbas que contienen una mezcla de materia vegetal además de cannabinoides de origen sintético. El Kratom, es un producto vegetal derivado de Mitragyna speciosa Korth que tiene efectos similares a los de los opioides, y que se emplea para el tratamiento del dolor crónico y el alivio de los síntomas de retirada de los opiáceos. La Salvia divinorum es un alucinógeno con u…

Effects of a single session of SMR neurofeedback training on anxiety and cortisol levels.

2020

Objectives: According to some studies, a putatively calming effect of EEG neurofeedback training could be useful as a therapeutic tool in psychiatric practice. With the aim of elucidating this possibility, we tested the efficacy of a single session of ¿sensorimotor (SMR)/¿theta neurofeedback training for mood improvement in 32 healthy men, taking into account trainability, independence and interpretability of the results. Methods: A pre-post design, with the following dependent variables, was applied: (i) psychometric measures of mood with regards to anxiety, depression, and anger (Profile of Mood State, POMS, and State Trait Anxiety Inventory, STAI); (ii) biological measures (salivary leve…

Drogas emergentes: catinonas sintéticas ('sales de baño')

2015

Las catinonas sintéticas son una nueva clase de drogas de diseño de tipo psicoestimulante y alucinógeno y con efectos similares a la cocaína, la metilendioximetanfetamina (MDMA) u otras anfetaminas. El abuso de catinonas sintéticas, con frecuencia incluidas en los productos vendidos como 'sales de baño', se puso de moda a principios de 2009, lo que llevó a la clasificación legislativa en toda Europa en 2010 y a la lista I de clasificación de drogas dentro de los Estados Unidos en 2011. Los estudios clínicos recientes indican que el mecanismo de acción de la catinona sintética afecta a los sistemas centrales de monoaminas. En esta revisión abordaremos la historia de estas drogas, su mecanism…

Eficacia del neurofeedback para el tratamiento de los trastornos del espectro autista: Una revisión sistemática

2015

Los trastornos del espectro autista (TEA) se caracterizan por deficits en la comunicacion e interaccion con los demas, patrones estereotipados de conducta e intereses restringidos. Presentan patrones de encefalograma (EEG) anomalos que podrian explicar estos deficits, y por ello el neurofeedback se plantea como una alternativa terapeutica dirigida a normalizarlos. El objetivo consistio en analizar el grado de eficacia del neurofeedback como tratamiento de los TEA. Se llevo a cabo una revision sistematica de 17 estudios empiricos localizados mediante busqueda bibliografica exhaustiva en PsycINFO, PsycArticles y Pubmed. Los resultados indican cierta eficacia del neurofeedback para tratar los …
