Not exact matches

The K - D test, originally developed in the 1980's by optometrists Al King and Steve Devick at the Illinois College of Optometry, provides objective measures of many aspects of brain function, including subcortical (subconscious) pathways that extend beyond eye movements.

Imaging scans show the brain shifts its activity (measured by blood flow and oxygenation, indicating which neurons are heavily used at a specific time) from the prefrontal executive control regions to subcortical reactive emotion areas.

«Typically, an overproduction of axons and synapses can be found during early puberty, followed by rapid pruning during later puberty, indicating that connections and communication between subcortical and cortical regions are in a highly transitional state during this period.»

The grand symphonic piece that is consciousness encompasses the foundational contributions of the brain stem, forever hitched to the body, and the wider - than - the - sky imagery created in the cooperation of cerebral cortex and subcortical structures, all harmoniously stitched together, in ceaseless forward motion, interruptible only by sleep, anesthesia, brain dysfunction, or death.

Contrary to previous assumptions, dopamine helps both strengthen and weaken synapses made by cortical cells onto cells of the subcortical striatum.

A new study led by Patrick F. Sullivan, MD, FRANZCP, a researcher and professor at both the University of North Carolina School of Medicine and the Karolinska Institutet in Stockholm, Sweden, evaluated the relationship between common genetic variants implicated in schizophrenia and those associated with subcortical brain volumes.

According to Irene Esteban - Cornejo, postdoctoral researcher at the University of Granada and main author of this paper, gray matter volume in the cortical and subcortical regions influenced by physical fitness improves in turn the children's academic performance.

Gross brain pathology from infants with presumed or laboratory - confirmed ZIKV infection, primarily from neuroimaging, closely resembles neuropathology associated with congenital cytomegalovirus (CMV).48 The most notable difference is the distribution of intracranial calcifications (ie, typically subcortical in congenital ZIKV infection and periventricular in CMV).48, 49 Such calcifications are likely dystrophic and related to cell death, either by necrosis, apoptosis, or both.50

Although many of the components of this syndrome, such as cognitive, sensory, and motor disabilities, are shared by other congenital infections, 5 features differentiate CZS from other congenital infections: (1) severe microcephaly with partially collapsed skull; (2) thin cerebral cortices with subcortical calcifications; (3) macular scarring and focal pigmentary retinal mottling; (4) congenital contractures; and (5) marked early hypertonia with symptoms of extrapyramidal involvement (Table).

The infant is a «subcortical creature... [who] lacks the means for modulation of behavior which is made possible by the development of cortical control» (Diamond, Balvin and Diamond, 1963, p. 305).

White matter volume was calculated by subtracting the subcortical and ventricular volumes from the volume bounded by the white matter surface.

These functional maps had large heterogeneous activations, so we parsed them by structure in MNI space to create a final set of functional masks using FSLView's Harvard - Oxford Cortical and Subcortical atlases.

Current neuroscience research indicates that insight and understanding may have only a limited influence on the operation of subcortical processes disrupted by traumatic and relational wounds of war.
