Oxytocin receptor genetic variation relates to empathy and stress reactivity in humans
tkoie 2010/01/08
Oxytocin reseptor gene (rs53576) was tested.Compared with GG individuals, AG/AA individuals exhibited lower behavioral and dispositional empathy, and an other-oriented empathy scale. AA/AG individuals displayed higher physiological and dispositional stress reactivity than GG individuals.

Influence of paced maternal breathing on fetalâ€“maternal heart rate coordination
tkoie 2009/07/15
Pregnant mothers often report a special awareness of and bonding with their unborn child.ã€€Little is known about this relationship. We find a clear increase in synchronization epochs mostly at high maternal respiratory rates in the original but not in the surrogate data.

the manner in which bilateral primary auditory cortex interact during speech and nonspeech processing is not well understood. --- we show a dissociation in neuronal interactions, occurring at both different hierarchal levels of the auditory system and in different hemispheres.

Theories of empathy should depend on affective, motor, and/or higher cognitive brain regions, but until recently no experimental method has been available to directly test these --- We found that empathically accurate, as compared with inaccurate, judgments.

Narrowing of intersensory speech perception in infancy â€” PNAS
tkoie 2009/06/19
Sensitivity to non-native languages,faces,vocalizations and music that is present early in life declines as infants acquire experience with native perceptual inputs.Our findings lend support to the notion that perceptual narrowing is a domain-general as well as a pan-sensory developmental process

Motivational states activate distinct hippocampal representations to guide goal-directed behaviors
tkoie 2009/06/16
beyond coding spatiotemporal context, hippocampal representations encode the relationships between internal states, the external environment, and action to provide a mechanism by which motivation and memory are coordinated to guide behavior.

Newborn infants perceive abstract numbers
tkoie 2009/06/12
we show that newborn infants spontaneously associate stationary, visual-spatial arrays of 4â€“18 objects with auditory sequences of events on the basis of number. Their performance provides evidence for abstract numerical representations at the start of postnatal experience.

Evidence on the emergence of the brain's default network from 2-week-old to 2-year-old healthy pediatric subjects
tkoie 2009/04/08
PCC/Rsp may serve as the main â€œhubâ€ of the default network as this region does in adults. In addition, although not as remarkable as the PCC/Rsp, the MPFC also emerges as a potential secondary hub starting from 1 year of age.

Medial temporal theta state before an event predicts episodic encoding success in humans
tkoie 2009/03/31
We report a human electrophysiological brain state that predicts successful memory for events before they occur. Using magnetoencephalographic recordings of brain activity during episodic memory encoding, we show that amplitudes of theta oscillations shortly preceding the onsets of words were higher
