Structural membrane contacts of somatic zone magnocellular perikaryons.

open access: yes, 2019
Magnocellular neurones establish different types of membrane contact with other supraoptic nucleus elements. (A) Soma-somatic membrane apposition of two adjacent magnocelluar neurones (MN1 and MN2) without intervening neuropil elements; MN1 and MN2 ...

Phylogenetic reduction of the magnocellular red nucleus in primates and inter-subject variability in humans

open access: yesFrontiers in Neuroanatomy
IntroductionThe red nucleus is part of the motor system controlling limb movements. While this seems to be a function common in many vertebrates, its organization and circuitry have undergone massive changes during evolution.

Backward Masking as a Test of Magnocellular Sensitivity

open access: yes, 2010
Backward masking has been proposed as a test of magnocellular sensitivity on the basis of the dual channel theory of masking. This proposal, however, faces the difficulty that the latency difference between magno- and parvocellular responses is much ...

Enhanced distraction by magnocellular salience signals in schizophrenia [PDF]

open access: yes, 2014
Research on schizophrenia has provided evidence of both impaired attentional control and dysfunctional magnocellular sensory processing. The present study tested the hypothesis that these impairments may be related, such that people with schizophrenia ...

Differential deficits in pattern- versus flash-visual evoked potentials in schizophrenia: relationship to subcortical visual systems, pulvinar nucleus and cognition

open access: yesFrontiers in Neuroimaging
BackgroundThe human subcortical visual system is divided into distinct magnocellular, parvocellular and koniocellular pathways, which contribute differentially to specific aspects of early visual processing.

Visual response latencies of magnocellular and parvocellular LGN neurons in macaque monkeys

open access: yes, 1999
Signals relayed through the magnocellular layers of the LGN travel on axons with faster conduction speeds than those relayed through the parvocellular layers.

Dyslexia, magnocellular integrity and rapidly presented stimuli

open access: yes, 2011
Conlon at al. (2011, Brain and Cognition, 76, 197-205) studied the responses of dyslexic readers and controls to rapidly presented stimuli. They found that the dyslexic readers showed poorer performance than the controls but only when the interstimulus ...

Neural correlates underlying naloxone-induced amelioration of sexual behavior deterioration due to an alarm pheromone

open access: yesFrontiers in Neuroscience, 2015
Sexual behavior is suppressed by various types of stressors. We previously demonstrated that an alarm pheromone released by stressed male Wistar rats is a stressor to other rats, increases the number of mounts needed for ejaculation, and decreases the ...

The magnocellular theory of developmental dyslexia.

open access: yes, 2001
Low literacy is termed 'developmental dyslexia' when reading is significantly behind that expected from the intelligence quotient (IQ) in the presence of other symptoms--incoordination, left-right confusions, poor sequencing--that characterize it as a ...

Optic Neuritis: From Magnocellular to Cognitive Residual Dysfunction

open access: yesBehavioural Neurology, 2013
Optic Neuritis (ON) has been associated to both parvocellular dysfunction and to an alteration of the magnocellular pathway. After objective visual field and acuity recovery, ON patients may complain about their vision suggesting a residual subclinical ...
