Numerical exploration of the influence of neural noise on the psychometric function
(2008)
The relationship between stimulus intensity and the probability of detecting the presence of the stimulus is described by the psychometrical function. The probabilistic nature of this relationship is based on the stochastic ...

Estudio de la memoria de trabajo desde la infancia a la adultez emergente y de su relacion con la inteligencia en sujetos en normodesarrollo y sujetos diagnosticados con TDA
(2024-01-19)
La Memoria de Trabajo (MT) es el sistema cerebral involucrado en el almacenamiento temporal de información (corto periodo de tiempo) y la manipulación de la misma. Este mecanismo posibilita la realización de tareas ...

A neurocognitive model for short-term sensory and motor preparatory activity in humans
(Universitat de Valencia, 2004)
The purpose of this review is to present information from different experiments that supports the proposal that brain systems are able to predict, in a short-term interval, ...

Children Cautious Strategy and Variable Maturation Time Window for Responding in a Visual Search Task
(Scientific Research Publishing, 2013)
Present study evaluates the changes and developmental trajectories of the attentional serial visual search and pre-attentional parallel search (pop-out) in situations in which a fast response is required. The hypothesis of ...

Exploring the Interactions Between Neurophysiology and Cognitive and Behavioral Changes Induced by a Non-pharmacological Treatment: A Network Approach
(Frontiers, 2021)
Dementia due to Alzheimer’s disease (AD) is a neurological syndrome which has an increasing impact on society, provoking behavioral, cognitive, and functional impairments. AD lacks an effective pharmacological intervention; ...

Mismatch Negativity and Stimulus-Preceding Negativity in Paradigms of Increasing Auditory Complexity: A Possible Role in Predictive Coding
(MDPI, 2021)
The auditory mismatch negativity (MMN) has been considered a preattentive index of auditory processing and/or a signature of prediction error computation. This study tries to demonstrate the presence of an MMN to deviant ...

Sequential P3 effects in a Posner’s spatial cueing paradigm: Trial-by-trial learning of the predictive value of the cue
(Polish Neuroscience Society, 2009)
The neurocognitive consequences of correct or incorrect spatial prediction in a sequential S1–S2 paradigm were assessed. Sequential dependence on previous trial outcome (valid or invalid) was assessed by late Event-Related ...

Trial-by-trial changes in a priori informational value of external cues and subjective expectancies in human auditory attention
(Public Library of Science, 2011)
Background: Preparatory activity based on a priori probabilities generated in previous trials and subjective expectancies would produce an attentional bias. However, preparation can be correct (valid) or incorrect (invalid) ...
