Neuromodulation of Visual Cortex Reduces the Intensity of Intrusive Memories.

Noa Herz, Yair Bar-Haim, Ido Tavor, Niv Tik, Haggai Sharon, Emily A Holmes, Nitzan Censor,

Aversive events can be reexperienced as involuntary and spontaneous mental images of the event. Given that the vividness of retrieved mental images is coupled with elevated visual activation, we tested whether neuromodulation of the visual cortex would reduce the frequency and negative emotional intensity of intrusive memories. Intrusive memories of ... Read more >>

Inhibition of the supplementary motor area affects distribution of effort over time.

Aviv Emanuel, Jasmine Herszage, Haggai Sharon, Nira Liberman, Nitzan Censor,

In tasks that extend over time, people tend to exert much effort at the beginning and the end, but not in the middle, exhibiting the stuck-in-the-middle pattern (STIM). To date, little is known about the neural mechanisms underlying this effect. As the supplementary motor area (SMA) was previously implicated in ... Read more >>

Intrusive memories: A mechanistic signature for emotional memory persistence.

Noa Herz, Yair Bar-Haim, Emily A Holmes, Nitzan Censor,

Memories of negative emotional events persist more over time relative to memories for neutral information. Such persistence has been attributed to heightened encoding and consolidation processes. However, reactivation of the encoded information may also lead to reduced memory decay through rehearsal or a reconsolidation processes. Here, we tested whether involuntary ... Read more >>

Explaining Individual Differences in Motor Behavior by Intrinsic Functional Connectivity and Corticospinal Excitability.

Jasmine Herszage, Eran Dayan, Haggai Sharon, Nitzan Censor,

Motor performance varies substantially between individuals. This variance is rooted in individuals' innate motor abilities, and should thus have a neural signature underlying these differences in behavior. Could these individual differences be detectable with neural measurements acquired at rest? Here, we tested the hypothesis that motor performance can be predicted ... Read more >>

Visual-oculomotor interactions facilitate consolidation of perceptual learning.

Shira Klorfeld-Auslender, Nitzan Censor,

Visual skill learning is commonly considered a manifestation of brain plasticity. Following encoding, consolidation of the skill may result in between-session performance gains. A great volume of studies have demonstrated that during the offline consolidation interval, the skill is susceptible to external inputs that modify the preformed representation of the ...

A Rapid Form of Offline Consolidation in Skill Learning.

Marlene Bönstrup, Iñaki Iturrate, Ryan Thompson, Gabriel Cruciani, Nitzan Censor, Leonardo G Cohen,

The brain strengthens memories through consolidation, defined as resistance to interference (stabilization) or performance improvements between the end of a practice session and the beginning of the next (offline gains) [1]. Typically, consolidation has been measured hours or days after the completion of training [2], but the same concept may ... Read more >>

Modulation of Learning and Memory: A Shared Framework for Interference and Generalization.

Jasmine Herszage, Nitzan Censor,

The human brain is known by its ability to modify and update existing memories, mediated by underlying neuronal plasticity. This ability is facilitated by two main phenomena, interference and generalization. Interference occurs when a new memory harms, or is being harmed by, a different memory that was acquired in temporal ... Read more >>

Susceptibility of consolidated procedural memory to interference is independent of its active task-based retrieval.

Ella Gabitov, Arnaud Boutin, Basile Pinsard, Nitzan Censor, Stuart M Fogel, Geneviève Albouy, Bradley R King, Julie Carrier, Leonardo G Cohen, Avi Karni, Julien Doyon,

Reconsolidation theory posits that upon retrieval, consolidated memories are destabilized and need to be restabilized in order to persist. It has been suggested that experience with a competitive task immediately after memory retrieval may interrupt these restabilization processes leading to memory loss. Indeed, using a motor sequence learning paradigm, we ... Read more >>

Consolidation of complex motor skill learning: evidence for a delayed offline process.

Diva Lugassy, Jasmine Herszage, Raphael Pilo, Tamar Brosh, Nitzan Censor,

Following initial acquisition, studies across domains have shown that memories stabilize through consolidation processes, requiring a post-acquisition temporal interval to allow their occurrence. In procedural skill memories, consolidation not only stabilizes the memory, but also simultaneously enhances it by accumulating additional gains in performance. In addition, explicit skill tasks were ... Read more >>

Neuromodulation of reinforced skill learning reveals the causal function of prefrontal cortex.

Eran Dayan, Jasmine Herszage, Rony Laor-Maayany, Haggai Sharon, Nitzan Censor,

Accumulating evidence has suggested functional interactions between prefrontal cortex (PFC) and dissociable large-scale networks. However, how these networks interact in the human brain to enable complex behaviors is not well-understood. Here, using a combination of behavioral, brain stimulation and neuroimaging paradigms, we tested the hypothesis that human PFC is required ... Read more >>

Re-stepping into the same river: competition problem rather than a reconsolidation failure in an established motor skill.

Ella Gabitov, Arnaud Boutin, Basile Pinsard, Nitzan Censor, Stuart M Fogel, Geneviève Albouy, Bradley R King, Habib Benali, Julie Carrier, Leonardo G Cohen, Avi Karni, Julien Doyon,

Animal models suggest that consolidated memories return to their labile state when reactivated and need to be restabilized through reconsolidation processes to persist. Consistent with this notion, post-reactivation pharmacological protein synthesis blockage results in mnemonic failure in hippocampus-dependent memories. It has been proposed that, in humans, post-reactivation experience with a ... Read more >>

Memory reactivation improves visual perception.

Rotem Amar-Halpert, Rony Laor-Maayany, Shlomi Nemni, Jonathan D Rosenblatt, Nitzan Censor,

Human perception thresholds can improve through learning. Here we report findings challenging the fundamental 'practice makes perfect' basis of procedural learning theory, showing that brief reactivations of encoded visual memories are sufficient to improve perceptual discrimination thresholds. Learning was comparable to standard practice-induced learning and was not due to short ... Read more >>

Memory Reactivation Enables Long-Term Prevention of Interference.

Jasmine Herszage, Nitzan Censor,

The ability of the human brain to successively learn or perform two competing tasks constitutes a major challenge in daily function. Indeed, exposing the brain to two different competing memories within a short temporal offset can induce interference, resulting in deteriorated performance in at least one of the learned memories [1-4]. Although ... Read more >>

Neural Variability Quenching Predicts Individual Perceptual Abilities.

Ayelet Arazi, Nitzan Censor, Ilan Dinstein,

Neural activity during repeated presentations of a sensory stimulus exhibits considerable trial-by-trial variability. Previous studies have reported that trial-by-trial neural variability is reduced (quenched) by the presentation of a stimulus. However, the functional significance and behavioral relevance of variability quenching and the potential physiological mechanisms that may drive it have ... Read more >>

Altered Human Memory Modification in the Presence of Normal Consolidation.

Nitzan Censor, Ethan R Buch, Karim Nader, Leonardo G Cohen,

Following initial learning, the memory is stabilized by consolidation mechanisms, and subsequent modification of memory strength occurs via reconsolidation. Yet, it is not clear whether consolidation and memory modification are the same or different systems-level processes. Here, we report disrupted memory modification in the presence of normal consolidation of human ... Read more >>
