Several lines of evidence show impaired right hemisphere function in depression. Lateralized simple reaction time tasks show impaired left visual field responses both in normals experiencing a depressed mood and in patients with mild unipolar depression. One interpretation for these findings is that depression impairs right hemisphere function by interfering with right hemisphere arousal and vigilance mechanisms. In order to test this hypothesis, subjects receiving either depression or… Expand

Mood and spatial memory: emotion and right hemisphere contribution to spatial cognition
TLDR
Normal university students examined to determine whether individual differences in mood and arousal levels would be related to performance on a spatial memory task, and a suggestion of right hemisphere sensitivity to mood in this normal sample was a tendency for the subjects high in Negative Arousal not to show the normal right hemisphere (left field) superiority for the spatial memorytask.

Emotional arousal modulation of right temporoparietal cortex in depression depends on parental depression status in women: first evidence.
TLDR
The results speak to the relevance of right temporoparietal dysfunction in emotional information processing as a potential endophenotype for depression with FH. Expand
Neural Basis of Depression Related to a Dominant Right Hemisphere: A Resting-State fMRI Study
TLDR
The results show that regional homogeneity mainly occurs in the right brain, and the overall performance of the brain is such that right Hemisphere synchronization is enhanced while left hemisphere synchronization is weakened. Expand
The role of the right hemisphere in the physiological and cognitive components of emotional processing.
TLDR
Right hemisphere specialization for emotional processing was investigated and selective right hemispheric activation in autonomic responses, combined with the lack of right hemisphere specialization in the cognitive task, suggests that the physiological response system rather than the perceptual/cognitive system is the locus of the right hemisphere superiority for emotion.

The Role of Functional Neuroimaging in the Neuropsychology of Depression

TLDR
Evidence strongly implicating the dorsolateral prefrontal cortex, particularly in the right hemisphere, as a key brain structure in emotion/cognition interactions in negative mood states is reviewed, suggesting this neocortical region is a crucial convergence zone. Expand
The blue brain : hemispheric asymmetry in depression as an explanation for working memory impairment : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Psychology at Massey University, Manawatu, New Zealand
Due to substantial variability in past research regarding the cognitive and neurobiological correlates of depression, the current study investigated whether taking the possible relationship between… Expand
Alertness and visuospatial attention in clinical depression
TLDR
Decreased alertness may lead to lower left hemifield visuospatial attention; this mechanism may be responsible for a spatial bias to the right side in depression, even though treatment of depression and anxiety may reduce this cognitive deficit. Expand
An fMRI study of prefrontal brain activation during multiple tasks in patients with major depressive disorder
TLDR
Patients with depression exhibit increased brain activation, especially in right prefrontal regions, across several types of cognitive task activity, which may recruit greater brain regions to achieve similar or even poorer task performance than control subjects. Expand
Mood Modulates Auditory Laterality of Hemodynamic Mismatch Responses during Dichotic Listening
TLDR
A lateralization effect of emotion-attention interaction was reflected in a stronger response to right-ear deviants in the right auditory cortex during sad mood, which may be a neurophysiological correlate of laterality in sad mood and depression. Expand
Neglect in action: a neuropsychological exploration of some behavioural aspects of neglect
In ten right hemisphere stroke patients the role of input (or attentional) and output (or intentional) factors in unilateral neglect was studied in two reaction time (RT) experiments. In the first… Expand

Differential hemispheric asymmetries in depression and anxiety: A reaction-time study
TLDR
Two alternative interpretations are discussed: depression may engage the right hemisphere's mechanisms, interfering with its functioning at a premotor level, or it may influence the regulation of performance by arousal and vigilance mechanisms lateralized to theright hemisphere, possibly operating at an earlier sensory stage. Expand
Right frontal lobe activation and right hemisphere performance. Decrement during a depressed mood.
TLDR
Observation that college students who reported greater depression also reported less vivid imagery suggest that anterior regions of the brain may modulate the differential effects of emotional arousal on the information-processing capacities of the cerebral hemispheres. Expand
Unilateral attention deficits and hemispheric asymmetries in the control of visual attention
TLDR
The results showed that patients with either left or right parietal damage are impaired in shifting attention from the ipsilateral to the contralateral visual field and, within each visual field, in a direction contraversive to the lesion and these two attentional deficits are more severe after right than after left parietalDamage. Expand
Right hemispheric dominance for mediating cerebral activation
TLDR
The hypothesis that the right hemisphere dominates activation is supported by results that reduce reaction times of the right hand more than warning stimuli projected to the left hemisphere reduced left hand reaction times. Expand
Simple reaction time: evidence for focal impairment from lesions of the right hemisphere.
Simple reaction time is significantly increased in patients with unilateral lesions of either cerebral hemisphere responding with the hand ipsilateral to the lesion, but the effect is much greater… Expand
Frontal and parietal electroencephalogram asymmetry in depressed and nondepressed subjects.
TLDR
Data support the hypothesis of right hemisphere hyperactivation in the frontal region of depressed individuals and are consistent with the growing body of literature which suggests that the left and right frontal regions may be differentially specialized for particular positive and negative affects.

[Disorders of autonomic responses to emotional stimuli in patients with unilateral hemispherical lesions].
TLDR
Both normal controls and left brain-damaged patients were very influenced by the emotional nature of the stimuli and showed clear signs of activation of the sympathetic and para-sympathetic systems in front of emotional films. Expand

Neuropsychological effects of electroconvulsive therapy.
TLDR
Compared pre- and posttreatment performances on the Halstead-Reitan neuropsychological battery of 20 patients who were receiving ECT from two different machines, most Ss gave indicators of cerebral impairment prior to treatment and after treatment, there was an increased number of Ss who evidenced signs consistent with damage to the right cerebral hemisphere.
