Hemodynamic changes in the infant cortex during the processing of featural and spatiotemporal information.

Over the last 20 years neuroscientists have learned a great deal about the ventral and dorsal object processing pathways in the adult brain, yet little is known about the functional development of these pathways. The present research assessed the extent to which different patterns of neural activation, as measured by changes in blood volume and oxygenation, are observed in infant visual and temporal cortex in response to events that involve processing of featural differences or spatiotemporal discontinuities. Infants aged 6.

Hemodynamic response to featural changes in the occipital and inferior temporal cortex in infants: a preliminary methodological exploration.

Over the past 30 years researchers have learned a great deal about the development of object processing in infancy. In contrast, little is understood about the neural mechanisms that underlie this capacity, in large part because there are few techniques available to measure brain functioning in human infants. The present research examined the extent to which near-infrared spectroscopy (NIRS), an optical imaging technique, could be used to assess the relation between object processing and brain functioning.

Assessing infants' cortical response to speech using near-infrared spectroscopy.

Sensitivity to spoken language is an integral part of infants' formative development, yet relatively little is known about the neural mechanisms that underlie the emerging ability to perceive and process speech. This is in large part because there are a limited number of non-invasive techniques available to measure brain functioning in human infants. Near-infrared spectroscopy (NIRS), an optical imaging technique that estimates changes in neuronal activity by measuring changes in total hemoglobin concentration and oxygenation, may be a viable procedure for assessing the relation between speech processing and brain function in human infants.

Using near-infrared spectroscopy to assess neural activation during object processing in infants.

The capacity to represent the world in terms of numerically distinct objects (i.e., object individuation) is a milestone in early cognitive development and forms the foundation for more complex thought and behavior.

Overhauling overtime standards. The Fair Labor Standards Act should be updated.

The minimum wage provisions of the Fair Labor Standards Act (1938) have drawn considerable attention through the years. But the act's overtime provisions have created some major problems yet generated little debate. As it now stands, the act stipulates that employees be paid overtime for hours worked in excess of 40 during a workweek.

[Penetrating heart injury].

A report was made on a 25 year old patient with a penetrating heart injury with basic diagnosis, and treatment. A successful management was a result of good performance of the resuscitation chain, exactness of the clinical diagnosis and interdisciplinary cooperation between surgeons and anaesthetists.

[Multicenter study of the results of the extraction of transvenously implanted heart-pacemaker electrodes using continuous traction].

The continuous traction of firmly grown-in collar electrodes from the right ventricle is a simple technique poor in complications with a high success rate, which can be recommended taking into consideration the indications in the failure of the immediate manual extraction and which can be performed in every centre for cardiac pacemakers. Apart from the consideration of adequate informations in literature this evidence above all depends on the evaluation of data of 29 cases from 10 centres for cardiac pacemakers.
