Proyecciones convergentes sobre el núcleo incertus en rata
2016
En un organismo animal, tanto la información procedente del entorno como la que proviene del medio interno ha de ser procesada, interpretada y almacenada mediante conexiones entre las distintas áreas del sistema nervioso central. Los centros superiores son los encargados del análisis y almacenamiento en forma de memoria de esta información. Estos centros superiores a su vez reciben proyecciones de núcleos subcorticales, cuya función, es la modulación de estos centros.En este trabajo ademas también proponemos la existencia de proyecciones desde los centros superiores hasta los núcleos subcorticales, generandose así un circuito tanto ascendente como descendente de la información.
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 …

Efectividad de un entrenamiento asistido por Neurofeedback, con correlatos de cortisol, en un caso clínico de ansiedad
2016
Neurofeedback treatments have shown successful results in anxiety disorders. The effectiveness of a betal Neurofeedback protocol was tested in a longitudinal clinical case study. A participant suffering from an anxiety syndrome underwent 10 sessions of Neurofeedback, in a protocol consisting of uptraining the betal rhythm (16-21 Hz) while downtraining the theta (4-8 Hz) band. State anxiety and salivary cortisol levels were measured during each of the 10 sessions following a pre/post design. Initial and final examinations of anxiety symptoms and sustained attention performance were also implemented. The final evaluation revealed that levels of anxiety fell within a normative range and that s…
