Neural Basis of Depression Related to a Dominant Right Hemisphere: A Resting-State fMRI Study

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.

The role of the right hemisphere in the physiological and cognitive components of emotional processing.

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

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.

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

Alertness and visuospatial attention in clinical depression

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.

An fMRI study of prefrontal brain activation during multiple tasks in patients with major depressive disorder

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.

Mood Modulates Auditory Laterality of Hemodynamic Mismatch Responses during Dichotic Listening

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.

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 and there was no evidence of directional hypokinesia, i.e. an independent delay in initiating a leftward directed movement.

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

Frontal and parietal electroencephalogram asymmetry in depressed and nondepressed subjects.

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.

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.
