Cognitive Profiles of Developmental Dysgraphia

open access: yesFrontiers in Psychology, 2018
Developmental dysgraphia is a disorder of writing/spelling skills, closely related to developmental dyslexia. For developmental dyslexia, profiles with a focus on phonological, attentional, visual or auditory deficits have recently been established ...

Perceptual deficits and inattention in schizophrenia

open access: yes, 2008
A number of investigators have found perceptual deficits in schizophrenic subjects. It has also been indicated that those with schizophrenia suffer from reduced attention.

Magnocellular and parvocellular pathway mediated luminance contrast discrimination in amblyopia

open access: yes, 2010
To evaluate whether luminance contrast discrimination losses in amblyopia on putative magnocellular (MC) and parvocellular (PC) pathway tasks reflect deficits at retinogeniculate or cortical sites.

The magnocellular deficit theory of dyslexia: the evidence from contrast sensitivity

open access: yes, 2000
A number of authors have made the claim that dyslexia is the result of a deficit in the magnocellular part of the visual system. Most of the evidence cited in support of this claim is from contrast sensitivity studies.

Simultaneous release of glutamate and acetylcholine from single magnocellular "cholinergic" basal forebrain neurons

open access: yes, 2006
Basal forebrain (BF) neurons provide the principal cholinergic drive to the hippocampus and cortex. Their degeneration is associated with the cognitive defects of Alzheimer's disease. Immunohistochemical studies suggest that some of these neurons contain

Neural Substrates for Early Data Reduction in Fast Vision: A Psychophysical Investigation

open access: yesBrain Sciences
To ensure survival, the visual system must rapidly extract the most important elements from a large stream of information. This necessity clashes with the computational limitations of the human brain, so a strong early data reduction is required to ...

Visual search deficits are independent of magnocellular deficits in dyslexia

open access: yes, 2011
The aim of this study was to investigate the theory that visual magnocellular deficits seen in groups with dyslexia are linked to reading via the mechanisms of visual attention.

Understanding reversal errors in dyslexia: the role of the magnocellular/dorsal visual stream

open access: yes, 2023
Although reversal errors (e.g., “b” vs. “d”) are often considered a hallmark of dyslexia, the origin of these errors remains elusive. Neuropsychological studies suggest that the magnocellular/dorsal visual stream may play an important role in our ability

Colocalization of vasopressin and oxytocin in hypothalamic magnocellular neurons in water−deprived rats

open access: yes, 2001
The posterior lobe hormones vasopressin and oxytocin are expressed in mutually−exclusive sets of magnocellular hypothamalic neurons. However, under certain functional conditions a partial coexpression has been observed.
