Learning to optimize perceptual decisions through suppressive interactions in the human brain
(2019-01)
Translating noisy sensory signals to perceptual decisions is critical for successful interactions in complex environments. Learning is known to improve perceptual judgments by filtering external noise and task-irrelevant ...
Unimodal and bimodal access to sensory working memories by auditory and visual impulses
(2019-11)
It is unclear to what extent sensory processing areas are involved in the maintenance of sensory information in working memory (WM). Previous studies have thus far relied on finding neural activity in the corresponding ...
Modulation of the pupillary response by the content of visual working memory
(2019-09)
Studies of selective attention during perception have revealed
modulation of the pupillary response according to the brightness
of task-relevant (attended) vs. -irrelevant (unattended) stimuli
within a visual display. ...
Hippocampal network abnormalities explain amnesia after VGKCC-Ab related autoimmune limbic encephalitis
(2019-05)
Objective Limbic encephalitis associated with antibodies to components of the voltage-gated potassium channel complex (VGKCC-Ab-LE) often leads to hippocampal atrophy and persistent memory impairment. Its long-term impact ...
The autoantibody-mediated encephalitides: from clinical observations to molecular pathogenesis
(2019-10)
The autoimmune encephalitis (AE) syndromes have been characterised by the detection of autoantibodies in serum and/or cerebrospinal fluid which target the extracellular domains of specific neuroglial antigens. The clinical ...
Premembering Experience: A Hierarchy of Time-Scales for Proactive Attention
(2019-10)
Memories are about the past, but they serve the future. Memory research often emphasizes the former aspect: focusing on the functions that re-constitute (re-member) experience and elucidating the various types of memories ...
Prospective task knowledge improves working memory-guided behaviour
(2019-07)
Working memory (WM) is the ability to keep information online for a forthcoming task. WM
theories have tended to focus on how sensory information is maintained, and less on how WM
content is used for guiding behaviour. ...
Sleep duration over 28 years, cognition, gray matter volume, and white matter microstructure: a prospective cohort study
(2020-01)
Study Objectives
To examine the association between sleep duration trajectories over 28 years and measures of cognition, gray matter volume, and white matter microstructure. We hypothesize that consistently meeting sleep ...
A common neural network architecture for visual search and working memory
(2020-09)
Visual search and working memory (WM) are tightly linked cognitive processes. Theories of
attentional selection assume that WM plays an important role in top-down guided visual search.
However, computational models of ...
Are People Ready for Personalized Brain Health? Perspectives of Research Participants in the Lifebrain Consortium
(2019-11)
Background and Objectives
A healthy brain is central to physical and mental well-being. In this multi-site, qualitative study, we investigated views and attitudes of adult participants in brain research studies on the ...
