Fos protein immunodetection was used to investigate the neuronal activation elicited in some olfactory-related areas after either learning of an olfactory discrimination task or its reactivation 10 d later. Trained rats (T) progressively acquired the association between one odor of a pair and water-reward in a four-arm maze. Two groups of…

Temporal lobe epilepsy (TLE) is often accompanied by interictal behavioral abnormalities, such as fear and memory impairment. To identify possible underlying substrates, we analyzed long-term synaptic plasticity in two relevant brain regions, the lateral amygdala (LA) and the CA1 region of the hippocampus, in the kindling model of epilepsy. Wistar…

Benzodiazepines have been useful tools for investigating mechanisms underlying learning and memory. The present set of experiments investigates the role of hippocampal GABA[subscript A]/benzodiazepine receptors in memory consolidation using Pavlovian fear conditioning. Rats were prepared with cannulae aimed at the dorsal hippocampus and trained…

Australian teachers in Church related schools have begun to use the term "spiritual intelligence" in their educational discourse. Is it accurate to describe spirituality as a form of intelligence? This paper explores whether the notion of spiritual intelligence is plausible. It addresses this firstly by discussing the notion of spiritual…

Through the discoveries of neuroscience, educators have moved beyond the intuitive knowledge of how and when learning occurs to a demonstrated scientific understanding of the learning process itself. These new understandings have a two-fold appeal to educators: they allow them to design better, research-based teaching practices, and they help them…

Individuals with fragile X mental retardation 1 ("FMR1") premutation (55 to 200 CGG repeats) are typically unaffected by fragile X syndrome. However, a subgroup of older males with the premutation have developed a neurological syndrome, which usually begins between 50 and 70 years and is associated with a progressive intention tremor and/or ataxia…

A critical step toward becoming a fluent reader is learning to recognize, name and distinguish the letters of the alphabet. This difficult task is often a point of failure. The task, however, can be made easier and less prone to failure. This article, based on research by cognitive scientists, provides guides for how to design a font that will…

Teachers are where the major strength of organizational control lies in the educational process; it is mainly they who restrict the quality of education and teaching and who are the irreplaceable factor in determining how well a school is run and its overall image. Therefore, once a teacher drain from higher education institutions begins, it is…

Paired associates and serial list memory are typically investigated separately. An "isolation principle" (J. B. Caplan, 2005) was proposed to explain behavior in both paradigms by using a single model, in which serial list and paired associates memory differ only in how isolated pairs of items are from interference from other studied items. In…

A good deal is now known about the neural circuitry involved in how conditioned fear can augment a simple reflex (fear-potentiated startle). This involves visual or auditory as well as shock pathways that project via the thalamus and perirhinal or insular cortex to the basolateral amygdala (BLA). The BLA projects to the central (CeA) and medial…

This study examined automatic processing of emotional faces in individuals with high-functioning Pervasive Developmental Disorders (HFPDD) using an affective priming paradigm. Sixteen participants (HFPDD and matched controls) were presented with happy faces, fearful faces or objects in both subliminal and supraliminal exposure conditions, followed…

Over the last few decades, long-term survival rates of children diagnosed with the two most common forms of childhood cancer, acute lymphoblastic leukemia (ALL) and brain tumors have improved substantially. Neurodevelopmental and psychosocial sequelae resulting from these diseases and their treatment have a direct impact on the developing brain…

Neurological examination of children includes the screening for soft neurological signs (NSS). There is little knowledge about their evolution during adolescence, except that their lasting presence has been associated with developmental, psychological, and cognitive disorders. We report the results of a NSS exam (assessing gross and fine motor…

Objective: Shaken Baby Syndrome (SBS) is now recognized as being the main cause of severe traumatic brain injury in infancy. However, our understanding of the impact of this type of abuse on child development remains sketchy. The main objective of the current study was therefore to shed light on the cognitive dysfunctions that are particular to…

The present study was designed to evaluate the effect of HIV/AIDS on cognitive control and to determine if the effect is modified by familial risk for either alcohol or mood disorders. Sixty HIV-1 seropositive and 75 seronegative volunteers were assigned to four subgroups defined by the crossing of a diagnosis of alcohol dependence in the…
