Feasibility of FreeSurfer Processing for T1-Weighted Brain Images of 5-Year-Olds: Semiautomated Protocol of FinnBrain Neuroimaging Lab
<p>Pediatric neuroimaging is a quickly developing field that still faces important methodological challenges. Pediatric images usually have more motion artifact than adult images. The artifact can cause visible errors in ...
Early development of negative and positive affect: Implications for ADHD symptomatology across three birth cohorts
<p>High levels of early emotionality (of either negative or positive valence) are hypothesized to be important precursors to early psychopathology, with attention-deficit/hyperactivity disorder (ADHD) a prime early target. ...
Infant and Child MRI: A Review of Scanning Procedures
Magnetic resonance imaging (MRI) is a safe method to examine human brain. However, a typical MR scan is very sensitive to motion, and it requires the subject to lie still during the acquisition, which is a major challenge ...
Maternal Anxiety Symptoms and Self-Regulation Capacity Are Associated With the Unpredictability of Maternal Sensory Signals in Caregiving Behavior
The unpredictability of maternal sensory signals in caregiving behavior has been recently found to be linked with infant neurodevelopment. The research area is new, and very little is yet known, how maternal anxiety and ...

Behavioral regulatory problems are associated with a lower attentional bias to fearful faces during infancy
<p>To investigate the role of early regulatory problems (RP), such as
problems in feeding, sleeping, and calming down during later
development, the association between parent‐reported RP at 3 months
(no‐RP, <i>n</i> = 110; ...
Neonatal Amygdala Volumes and the Development of Self-Regulation from Early Infancy to Toddlerhood
<p><i>Objective:</i> At the broadest level, self-regulation refers to a
range of separate, but inter-related, processes (e.g., working memory,
inhibition, emotion regulation) central for the regulation of cognition,
emotion ...
The role of alexithymia and perceived stress in mental health responses to COVID-19: A conditional process model
<p><strong>Background</strong><br>Little is known about the psychological mechanisms underlying the mental health problems related to the COVID-19 pandemic. Hypothetically, perceived stress and alexithymia may be factors ...
Infant fecal microbiota composition and attention to emotional faces
The gut microbiota has been suggested to influence neurodevelopment in
rodents. Preliminary human studies have associated fecal microbiota
composition with features of emotional and cognitive development as well
as differences in thalamus-amygdala connectivity. Currently,
microbiota-gut-brain axis studies cover heterogenous set of infant and
child brain developmental phenotypes, while microbiota associations with
more fine-grained aspects of brain development remain largely unknown.
Here (N = 122, 53% boys), we investigated the associations
between infant fecal microbiota composition and infant attention to
emotional faces, as bias for faces is strong in infancy and deviations
in early processing of emotional facial expressions may influence the
trajectories of social-emotional development. The fecal microbiota
composition was assessed at 2.5 months of age and analyzed with 16S rRNA
gene sequencing. Attention to emotional faces was assessed with an
age-appropriate face-distractor paradigm, using neutral, happy, fearful,
and scrambled faces and salient distractors, at 8 months of age. We
observed an association between a lower abundance of Bifidobacterium and a higher abundance of Clostridium
with an increased “fear bias,” that is, attention toward fearful versus
happy/neutral faces. This data suggests an association between early
microbiota and later fear bias, a well-established infant phenotype of
emotionally directed attention. However, the clinical significance or
causality of our findings remains to be assessed....
