Fish Oil Diet Associated with Acute Reperfusion Related Hemorrhage, and with Reduced Stroke-Related Sickness Behaviors and Motor Impairment

TL;DR: In surviving animals, PUFA supplementation did not influence infarct size as determined 6 weeks after surgery, but did decrease omega-6-fatty-acid levels, moderate sickness behaviors, acute motor impairment, and longer-term locomotor hyperactivity and depression/anxiety-like behavior.
Journal ArticleDOI

A normative and reliability study for the Raven's Coloured Progressive Matrices for primary school aged children from Victoria, Australia.

TL;DR: In this paper, the results of a normative and reliability study on the Raven's Coloured Progressive Matrices (CPM) are reported for a sample of 618 children from Victoria Australia ranging in age from 6.00 to 11.92 years.
Journal ArticleDOI

A role for the 'magnocellular advantage' in visual impairments in neurodevelopmental and psychiatric disorders.

TL;DR: A new integrated model of visual processing based on primate single cell and human electrophysiology may provide a framework to understand how the visual system is involved, by implicating the magnocellular pathway's role in driving attentional mechanisms in higher-order cortical regions, what it is argued to be important for future research highlighting visual aspects of impairment in disorders as diverse as schizophrenia and autism.
Journal ArticleDOI

Separate magnocellular and parvocellular contributions from temporal analysis of the multifocal VEP

TL;DR: The second-order responses of the multifocal cortical visual evoked potential show a first slice which is predominantly driven by neural elements that have a latency and contrast function that mimic those of the magnocellular neurons of the primate LGN and a second slices which is dominated by a generator whose properties resemble primate parvocellular function.
Journal ArticleDOI

Evidence for Fast Signals and Later Processing in Human V1/V2 and V5/MT+: A TMS Study of Motion Perception

TL;DR: Very early activation of V5/MT+, evidenced by diminished accuracy and reduced perception of motion after TMS may be indicative of a thalamic-extrastriate pathway in addition to the traditionally expected later period of processing.
