Neural Mechanisms of Visual Mental Imagery in the Healthy and Damaged Brain
In the absence of visual input from the external world, humans are able to internally generate vivid mental images of external stimuli. This cognitive process is known as visual mental imagery, and…
Assessing the causal role of early visual areas in visual mental imagery
TLDR
A model of visual mental imagery based on neuroimaging findings that involves large-scale brain networks spanning prefrontal areas to sensory areas, and that highlights the activation of occipital areas during visualmental imagery is outlined.
Visual and Motor Mental Imagery After Brain Damage
TLDR
This chapter presents evidence from brain-damaged patients relevant to the debate concerning the neural underpinnings of visual and motor mental imagery capacities, and indicates that such a close correspondence only exists for motor imagery.
Vivid visual mental imagery in the absence of the primary visual cortex
TLDR
It is shown that in spite of his near-complete cortical blindness, SBR exhibits vivid visual mental imagery both behaviorally and when measured with functional magnetic resonance imaging.
The connectional anatomy of visual mental imagery: evidence from a patient with left occipito-temporal damage.
TLDR
The connectional anatomy of the FIN is described in neurotypical participants and in RDS, a right-handed patient with an extensive occipito-temporal stroke in the left hemisphere, and it is found that the FIN was spared by the lesion.
The neural correlates of visual mental imagery: An ongoing debate
The connectional anatomy of visual mental imagery: evidence from a patient with left occipito-temporal damage
TLDR
The connectional anatomy of FIN is described in neurotypical participants and in RDS, a right-handed patient with an extensive occipitotemporal stroke in the left hemisphere, and it is found that the FIN was spared by the lesion.
Loss of imagery phenomenology with intact visuo-spatial task performance: A case of ‘blind imagination’
Visual mental imagery engages the left fusiform gyrus, but not the early visual cortex: A meta-analysis of neuroimaging evidence
TLDR
A revised neural model of VMI is proposed that draws inspiration from recent cytoarchitectonic and lesion studies, whereby fronto-parietal networks initiate, modulate, and maintain activity in a core temporal network centered on the fusiform imagery node, a high-level visual region in the left fusodus gyrus.
Hemispheric asymmetries in visual mental imagery
TLDR
A critical review of the available literature on the hemispheric laterality of visual mental imagery, by looking at cross-method patterns of evidence in the domains of lesion neuropsychology, neuroimaging, and direct cortical stimulation suggests that visualmental imagery relies on large-scale brain networks, with a crucial participation of high-level visual regions in the temporal lobe.

TLDR
It is concluded that rich internal representations can be activated to support visual imagery even when they cannot support visually mediated perception of objects.

Functional Anatomy of High-Resolution Visual Mental Imagery
TLDR
There is strong evidence that imagery based on verbal descriptions can recruit regions known to be engaged in high-order visual processing and region activation in other regions was very similar in the two conditions.
Cortical blindness and visual imagery
TLDR
Investigations of three patients with cortical blindness provide strong evidence that primary visual cortices are not essential for the mediation of visual images recalled from memory.
Visual mental imagery induces retinotopically organized activation of early visual areas.
TLDR
Event-related analysis revealed that the imagery (greater than either form of attention) retinotopic maps were similar to the perception maps, and blocked analysis revealed similar perception and imagery effects in human motion processing region MT+.
