Mental Training Affects Distribution of Limited Brain Resources
TLDR
This study shows that meditation, or mental training, affects the distribution of limited brain resources, and supports the idea that plasticity in brain and mental function exists throughout life and illustrates the usefulness of systematic mental training in the study of the human mind.
Neural substrates of cognitive capacity limitations
TLDR
Together, these results suggest visual capacity limitation is due to discrete, slot-like, resources, each containing limited pools of neural information that can be divided among objects.
attentional bottleneck in the human brain
TLDR
It is concluded that a unified attentional bottleneck, including the inferior frontal junction, superior medial frontal cortex, and bilateral insula, temporally limits operations as diverse as perceptual encoding and decision-making.

Neural Competition for Conscious Representation across Time: An fMRI Study
TLDR
FMRI data are consistent with the notion that the attentional blink is related to attentional demands of T1 for selection, and indicate that these demands are reflected at the level of visual cortex.
Brain Mechanisms of Serial and Parallel Processing during Dual-Task Performance
The psychological refractory period (PRP) refers to the fact that humans typically cannot perform two tasks at once. Behavioral experiments have led to the proposal that, in fact, peripheral
Central as well as Peripheral Attentional Bottlenecks in Dual-Task Performance Activate Lateral Prefrontal Cortices
TLDR
Differences between the CB and PB groups with respect to the exact prefrontal areas activated and the correlational patterns suggest that the executive functions resolving interference at least partially differ between the groups.

Capacity limit of visual short-term memory in human posterior parietal cortex
TLDR
Functional magnetic resonance imaging is used to suggest that activity in the posterior parietal cortex is tightly correlated with the limited amount of scene information that can be stored in visual short-term memory, and suggests that the posterior PAR cortex is a key neural locus of the authors' impoverished mental representation of the visual world.
The neural basis of the central executive system of working memory
TLDR
Using functional magnetic resonance imaging to examine brain activation during the concurrent performance of two tasks, which is expected to engage the CES, results support the view that the prefrontal cortex is involved in human working memory.
Neural Correlates of the Attentional Blink
The Neural Fate of Consciously Perceived and Missed Events in the Attentional Blink
Modulation of long-range neural synchrony reflects temporal limitations of visual attention in humans.
TLDR
This work hypothesized that the network communicates by means of neural phase synchronization, and used magnetoencephalography to study transient long-range interarea phase coupling in a well studied attentionally taxing dual-target task (attentional blink).
The prefrontal cortex and working memory: physiology and brain imaging
Neural activity predicts individual differences in visual working memory capacity
TLDR
This work provides electrophysiological evidence for lateralized activity in humans that reflects the encoding and maintenance of items in visual memory and provides a strong neurophysiological predictor of an individual's capacity, allowing a direct relationship between neural activity and memory capacity.
Neural Systems for Visual Orienting and Their Relationships to Spatial Working Memory
TLDR
The IPs and FEF form a dorsal network that controls the endogenous allocation and maintenance of visuospatial attention and it is proposed that this cortical network is important for reorienting to sensory events.
