Is neuroenhancement by noninvasive brain stimulation a net zero-sum proposition?
AK Brem, PJ Fried, JC Horvath, EM Robertson… - Neuroimage, 2014 - Elsevier
In the past several years, the number of studies investigating enhancement of cognitive
functions through noninvasive brain stimulation (NBS) has increased considerably. NBS …

Different computations underlie overt presaccadic and covert spatial attention
Perception and action are tightly coupled: visual responses at the saccade target are
enhanced right before saccade onset. This phenomenon, presaccadic attention, is a form of …

Partially overlapping spatial environments trigger reinstatement in hippocampus and schema representations in prefrontal cortex
When we remember a city that we have visited, we retrieve places related to finding our goal
but also non-target locations within this environment. Yet, understanding how the human …

Differential impact of endogenous and exogenous attention on activity in human visual cortex
How do endogenous (voluntary) and exogenous (involuntary) attention modulate activity in
visual cortex? Using ROI-based fMRI analysis, we measured fMRI activity for valid and …

Reduced fidelity of neural representation underlies episodic memory decline in normal aging
Emerging studies have emphasized the importance of the fidelity of cortical representation in
forming enduring episodic memory. No study, however, has examined whether there are …

[HTML][HTML] Feature-based attention enhances performance by increasing response gain
K Herrmann, DJ Heeger, M Carrasco - Vision research, 2012 - Elsevier
Covert spatial attention can increase contrast sensitivity either by changes in contrast gain or
by changes in response gain, depending on the size of the attention field and the size of the …

Complementary role of frontoparietal activity and cortical pattern similarity in successful episodic memory encoding
One central goal in cognitive neuroscience of learning and memory is to characterize the
neural processes that lead to long-lasting episodic memory. In addition to the stronger …

Attention enhances contrast appearance via increased input baseline of neural responses
EK Cutrone, DJ Heeger, M Carrasco - Journal of vision, 2014 - jov.arvojournals.org
Covert spatial attention increases the perceived contrast of stimuli at attended locations,
presumably via enhancement of visual neural responses. However, the relation between …

Parallel engagement of regions associated with encoding and later retrieval forms durable memories
The fate of a memory is partly determined at initial encoding. However, the behavioral
consequences of memory formation are often tested only once and shortly after learning …

How attention extracts objects from noise
The visual system is remarkably proficient at extracting relevant object information from
noisy, cluttered environments. Although attention is known to enhance sensory processing …
