Changes in P3b Latency and Amplitude Reflect Expertise Acquisition in a Football Visuomotor Learning Task. [PDF]

open access: yesPLoS ONE, 2016
Learning is not a unitary phenomenon. Rather, learning progresses through stages, with the stages reflecting different challenges that require the support of specific cognitive processes that reflect the functions of different brain networks. A theory of

Quantifying Intermodal Distraction by Emotion During Math Performance: An Electrophysiological Approach

open access: yesFrontiers in Psychology, 2019
Emotionally engaging stimuli are powerful competitors for limited attention capacity. In the cognitive neuroscience laboratory, the presence of task-irrelevant emotionally arousing visual distractors prompts decreased performance and attenuated brain ...

A componential analysis of the ERP elicited by novel events using a dense electrode array [PDF]

open access: yes, 1999
In this study, we examined the relationship between the novelty P3 and the P300 components of the brain event‐related potential (ERP). Fifteen subjects responded manually to the rare stimuli embedded either in a classical auditory oddball series or in a ...

Mapping the Human Brain in Frequency Band Analysis of Brain Cortex Electroencephalographic Activity for Selected Psychiatric Disorders

open access: yesFrontiers in Neuroinformatics, 2018
There are still no good quantitative methods to be applied in psychiatric diagnosis. The interview is still the main and most important tool in the psychiatrist work.

Sex differences in electrophysiology: P200 event-related potential evidence

open access: yesTranslational Neuroscience, 2018
We conducted an event-related potential (ERP) study using a 256-channel dense sensor array electroencephalography (EEG) system to examine how, and if the P200 neurophysiological signal is sexually dimorphic. We had two groups of participants: females (n=

New Protocol for Quantitative Analysis of Brain Cortex Electroencephalographic Activity in Patients With Psychiatric Disorders

open access: yesFrontiers in Neuroinformatics, 2018
The interview is still the main and most important tool in psychiatrist's work. The neuroimaging methods such as CT or MRI are widely used in other fields of medicine, for instance neurology.

Discrimination Between Brain Cognitive States Using Shannon Entropy and Skewness Information Measure [PDF]

open access: yes, 2020
Non-invasive brain imaging techniques are popular tools for monitoring the cognitive state of human participants. This work builds on our previous studies using the HydroCel Geodesic Sensor Net, 256 electrodes dense-array electro-encephalography (EEG ...

Dynamic Responses in Brain Networks to Social Feedback: A Dual EEG Acquisition Study in Adolescent Couples

open access: yesFrontiers in Computational Neuroscience, 2017
Adolescence is a sensitive period for the development of romantic relationships. During this period the maturation of frontolimbic networks is particularly important for the capacity to regulate emotional experiences.

Weak surround suppression of the attentional focus characterizes visual selection in the ventral stream in autism

open access: yesNeuroImage: Clinical, 2018
Neurophysiological findings in the typical population demonstrate that spatial scrutiny for visual selection determines a center-surround profile of the attentional focus, which is the result of recurrent processing in the visual system. Individuals with

Maskless Fabrication of PLA‐Based Neural Arrays for CNS Recording and Stimulation

open access: yesAdvanced Materials Interfaces, EarlyView.
Biodegradable neural interfaces enable bidirectional communication with the CNS. Through electrochemical characterization, ageing tests with impedance monitoring, and in vivo validation, we assess the performance of PLA‐based epicortical and spinal implants.
