Active (new and reactivated) memories are considered to be labile sensitive treatments disrupting the time-dependent consolidation/reconsolidation processes required for their stabilization. also allow integration of new information updating memories. Here, we investigate possibility that, when active, internal state provided by amnesic is represented integrated within initial memory that amnesia results from absence this at testing. We showed in rats resulting systemic,...
Omega-3 fatty acids are important for several neuronal and cognitive functions. Altered omega-3 acid status has been implicated in reduced resistance to stress mood disorders. We therefore evaluated the effects of repeated restraint (6 h/day 21 days) on adult rats fed deficient, control or enriched diets from conception. measured body weight, plasma corticosterone hippocampus glucocorticoid receptors correlated these data with emotional depression-like behaviour assessed by their open-field...
To assess the role of prelimbic (PL) and infralimbic (IL) cortices in mediating strategy switching, rats were trained a new automated task Y-maze allowing careful analysis rats' behavior. In this situation, can only use two egocentric (Right, Left) visual (Light, Dark) strategies. first experiment, with PL, IL, or PL/IL lesions compared sham-operated when to reach criterion 10 consecutive correct responses light before being response (rule shifting), finally reversed (reversal). second...
In the present review, we provide evidence indicating that although post traumatic stress disorder (PTSD) and substance use (SUD) are two distinct pathologies with very different impacts on people affected by these chronic illnesses, they share numerous common characteristics, high rates of co-morbidity, may result from a source. We propose hyper reactivity to reminders, thus should be considered as disorders memory, treated such. review possibilities intervene pathological memories such...
The effects of ibotenic lesions the hippocampus on conditioning to contextual cues during classical fear in rats were evaluated by (a) amount freezing elicited and (b) relative avoidance a shock compartment. In Experiment 1, had no effect marginally affected after repeated sessions. 2 showed that disrupted when tested single session, while leaving unaffected acquisition freezing. 3 indicated these decreased higher footshock intensity was used but These results show do not quantify context...
Following partial training in an avoidance brightness discrimination task a Y-maze, the retention performance can be enhanced by pretest exposure to various features (prior cuing). The effectiveness of these cues may vary as function length interval. These results demonstrate that prior cuing promotes retrieval memory trace and is submitted long-lasting time-dependent reorganization. present experiments were designed examine involvement hippocampal formation processes promoted cuing. Rats...
In order to investigate the respective roles of dorsal and ventral parts medial prefrontal cortex (mPFC) on a delayed alternation task, acquisition which is disrupted by large mPFC lesions (Winocur, 1991), rats with circumscribed anterior cingulate (ACd) or prelimbicinfralimbic (PL-IL) were compared. As was predicted, ACd severely impaired performance, an analysis results suggests involvement this region in sequencing temporally ordered behavior. On other hand, PL-IL had no effect, finding...
Rats trained in a dual-solution cross-maze task, which can be solved by place and response strategies, predominantly used strategy after extensive training. This paper examines the involvement of medial lateral dorsal striatum (mDS lDS) choice these strategies partial Our results show that rats with lDS mDS lesions mainly from early phase We replicated unexpected data confirmed their tendency to use modified task. When water maze however, control lesioned consistently strategy, demonstrating...
Recently, the field of animal memory research has seen a resurgence interest in mechanisms underlying retrograde amnesia (RA) and use RA as technique for studying processes. A recent report from major neuroscience lab, which demonstrated an old reactivated memory, revitalized debate regarding widely accepted memory-consolidation theory RA. Here, we discuss number characteristics consider findings that led to development hypothesis, well those suggesting alternative retrieval-deficit explanation.
