The background of reduced face specificity of N170 in congenital prosopagnosia. [PDF]

PLoS ONE, 2014
Congenital prosopagnosia is lifelong face-recognition impairment in the absence of evidence for structural brain damage. To study the neural correlates of congenital prosopagnosia, we measured the face-sensitive N170 component of the event-related ...

From Feedback-Learning to Semantic Memory: Can Feedback-Related Brain Activity Predict Object-Word Associations? [PDF]

Psychophysiology
ABSTRACT This study investigated the neural mechanisms underlying feedback‐based learning of novel‐object‐novel‐word associations, focusing on how feedback‐locked event‐related potentials acquired during learning relate to subsequent memory performance and acquired association strength.

Links Between Altered Feedback Learning and Symptoms of Depression: Insights From the FRN and Feedback-Locked N170. [PDF]

Psychophysiology
ABSTRACT Blunted electrophysiological and striatal responses to reward have been suggested as biomarkers or endophenotypes for depression. However, previous studies did not differentiate between learning from immediate and learning from delayed feedback, which involves different neural structures.

Nudging the N170 forward with prior stimulation—Bridging the gap between N170 and recognition potential [PDF]

Human Brain Mapping, 2020
Abstract Evoked response potentials are often divided up into numerous components, each with their own body of literature. But is there less variety than we might suppose? In this study, we nudge one component into looking like another.

Misinterpreting Electrophysiology in Human Cognitive Neuroscience [PDF]

Psychophysiology
ABSTRACT An axiomatic view in contemporary neuroscience is that EEG components such as event‐related brain potentials (ERPs) and oscillations are directly interpretable as manifestations of biological processes that support sensory, motor, and cognitive constructs of interest.

Action or Stimulus: Individual Beliefs About Learned Associations Influence the Processing of Immediate and Delayed Feedback [PDF]

Eur J Neurosci
Individual beliefs on whether feedback refers to a previous action or a previous stimulus affects feedback processing: The feedback‐related negativity, possibly indicating striatal activity, showed stronger feedback valence coding across feedback delays, while the N170, possibly indicating medial temporal lobe activity, showed stronger prediction error

The Unfulfilled Promise of the N170 as a Social Biomarker

Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, 2020
Greater affordability and accessibility of noninvasive brain imaging techniques have led to an increased interest in identifying biomarkers of various cognitive processes, particularly in the field of neurodevelopmental disabilities. Autism spectrum disorder (ASD) is one area of research in which strong claims in support of brain-based biomarkers, such

A neurophysiological signature of dynamic emotion recognition associated with social communication skills and cortical gamma-aminobutyric acid levels in children

Frontiers in Neuroscience, 2023
IntroductionEmotion recognition is a core feature of social perception. In particular, perception of dynamic facial emotional expressions is a major feature of the third visual pathway.

N170 Tuning in Chinese: Logographic Characters and Phonetic Pinyin Script [PDF]

Scientific Studies of Reading, 2016
In alphabetic languages, print consistently elicits enhanced, left-lateralized N170 responses in the event-related potential compared to control stimuli. In the current study, we adopted a cross-linguistic design to investigate N170 tuning to logographic Chinese and to pinyin, an auxiliary phonetic system in Chinese.

Mass-univariate analysis of scalp ERPs reveals large effects of gaze fixation location during face processing that only weakly interact with face emotional expression

Scientific Reports, 2023
Decoding others’ facial expressions is critical for social functioning. To clarify the neural correlates of expression perception depending on where we look on the face, three combined gaze-contingent ERP experiments were analyzed using robust mass ...
