Repetition suppression of faces is modulated by emotion [PDF]

Proceedings of the National Academy of Sciences, 2004
Single-unit recordings and functional brain imaging studies have shown reduced neural responses to repeated stimuli in the visual cortex. By using event-related functional MRI, we compared the activation evoked by repetitions of neutral and fearful faces, which were either task relevant (targets) or irrelevant (distracters).

Spatially-Specific Repetition Suppression in Transsaccadic Perception

Journal of Vision, 2015
Brain representations of visual space are predominantly eye-centered (retinotopic) yet our experience of the world is largely world-centered (spatiotopic). A long-standing question is how the brain creates continuity between these reference frames across successive eye movements (saccades).

fMRI Repetition Suppression: Neuronal Adaptation or Stimulus Expectation? [PDF]

Cerebral Cortex, 2011
Measurements of repetition suppression with functional magnetic resonance imaging (fMRI adaptation) have been used widely to probe neuronal population response properties in human cerebral cortex. fMRI adaptation techniques assume that fMRI repetition suppression reflects neuronal adaptation, an assumption that has been challenged on the basis of ...

Long-time Low-latency Quantum Memory by Dynamical Decoupling [PDF]

, 2013
Quantum memory is a central component for quantum information processing devices, and will be required to provide high-fidelity storage of arbitrary states, long storage times and small access latencies.

Repetitive Control of Electrical Stimulation for Tremor Suppression [PDF]

IEEE Transactions on Control Systems Technology, 2019
Tremor is a rapid involuntary movement often seen in patients with neurological conditions such as multiple sclerosis and Parkinson’s disease. This debilitating oscillation can be suppressed by applying functional electrical stimulation (FES) within a closed-loop control system.

Repetition suppression in aging: A near-infrared spectroscopy study on the size-congruity effect

NeuroImage, 2017
Age-related changes in the hemodynamic response regarding inhibition capacity and repetition suppression were examined using a modified version of the numerical Stroop task.

Single-exposure visual memory judgments are reflected in inferotemporal cortex

eLife, 2018
Our visual memory percepts of whether we have encountered specific objects or scenes before are hypothesized to manifest as decrements in neural responses in inferotemporal cortex (IT) with stimulus repetition.

Diverse temporal dynamics of repetition suppression revealed by intracranial recordings in human ventral temporal cortex

bioRxiv, 2019
Repeated stimulus presentations commonly produce decreased neural responses - a phenomenon known as repetition suppression (RS) or adaptation – in ventral temporal cortex (VTC) in humans and nonhuman primates.

Measures of repetition suppression in the fusiform face area are inflated by co-occurring effects of statistically learned visual associations

Cortex, 2019
Repeated presentation of a stimulus leads to reductions in measures of neural responses. This phenomenon, termed repetition suppression (RS), has recently been conceptualized using models based on predictive coding, which describe RS as due to ...
