Involvement of the hippocampus, amygdala, entorhinal cortex and posterior parietal cortex in memory consolidation

A total of 182 young adult male Wistar rats were bilaterally implanted with cannulae into the CA1 region of the dorsal hippocampus and into the amygdaloid nucleus, the entorhinal cortex, and the posterior parietal cortex. After recovery, the animals were trained in a step-down inhibitory avoidance task. At various times after training (0, 30, 60 or 90 min) the animals received a 0.5-µl microinfusion of vehicle (saline) or 0.5 µg of muscimol dissolved in the vehicle. A retention test was carried out 24 h after training. Retention test performance was hindered by muscimol administered into both the hippocampus and amygdala at 0 but not at 30 min posttraining. The drug was amnestic when given into the entorhinal cortex 30, 60 or 90 min after training, or into the parietal cortex 60 or 90 min after training, but not before. These findings suggest a sequential entry operation, during the posttraining period, of the hippocampus and amygdala, the entorhinal cortex, and the posterior parietal cortex in memory processing

Panic-like defensive behavior but not fear-induced antinociception is differently organized by dorsomedial and posterior hypothalamic nuclei of Rattus norvegicus (Rodentia, Muridae)

The hypothalamus is a forebrain structure critically involved in the organization of defensive responses to aversive stimuli. Gamma-aminobutyric acid (GABA)ergic dysfunction in dorsomedial and posterior hypothalamic nuclei is implicated in the origin of panic-like defensive behavior, as well as in pain modulation. The present study was conducted to test the difference between these two hypothalamic nuclei regarding defensive and antinociceptive mechanisms. Thus, the GABA A antagonist bicuculline (40 ng/0.2 µL) or saline (0.9% NaCl) was microinjected into the dorsomedial or posterior hypothalamus in independent groups. Innate fear-induced responses characterized by defensive attention, defensive immobility and elaborate escape behavior were evoked by hypothalamic blockade of GABA A receptors. Fear-induced defensive behavior organized by the posterior hypothalamus was more intense than that organized by dorsomedial hypothalamic nuclei. Escape behavior elicited by GABA A receptor blockade in both the dorsomedial and posterior hypothalamus was followed by an increase in nociceptive threshold. Interestingly, there was no difference in the intensity or in the duration of fear-induced antinociception shown by each hypothalamic division presently investigated. The present study showed that GABAergic dysfunction in nuclei of both the dorsomedial and posterior hypothalamus elicit panic attack-like defensive responses followed by fear-induced antinociception, although the innate fear-induced behavior originates differently in the posterior hypothalamus in comparison to the activity of medial hypothalamic subdivisions.

Estado e economia na Coreia do Sul - do Estado desenvolvimentista à crise asiática e à recuperação posterior

The State and the economy in South Korea: from the developmentist state to the Asian crisis and later recovery. The article focuses on the institutions of South Korean capitalism and on the interactions between the state and the economy. The economic model in South Korea was characterized by a very interventionist state, which played a very active role in the process of industrialization. However, South Korea suffered a severe crisis in 1997, attributed by many authors to the distortions inherent to strong state intervention. The article shows that the crisis was a result of the combination between internal economic fragilities and a rapid process of financial deregulation, which undermined the state's capacity of control. The crisis, nevertheless, does not disqualify the role of the national institutions in the very successful process of industrialization. Despite the reforms, the Korean capitalism conserves much of the previous model of business organization and industrial relations. The state continues strong and played active role in the process of economic reforms. There are, nevertheless, doubts about the impacts of the reforms and the new configuration of Korean capitalism. They will depend on the current transformations in world economy and in the East Asian countries.

Quantification of standing balance in survivors of childhood posterior fossa brain tumours

Malgré un intérêt grandissant pour la question du devenir des survivants de tumeur cérébrale pédiatrique, l’évaluation de leur équilibre est souvent négligée. Les objectifs de nos travaux étaient de 1) examiner les écrits portant sur l’équilibre chez les survivants de tumeur cérébrale pédiatrique; 2) comparer l'équilibre debout et la qualité de vie entre les survivants et un groupe d’enfants témoins; et 3) examiner l'association entre l'équilibre debout et qualité de vie chez les survivants. Notre recension des écrits démontra que les survivants de tumeur cérébrale présentent des troubles de l’équilibre, mais les limites méthodologiques des études nous empêchent de conclure de manière définitive. Ensuite, nous avons recruté un groupe d’enfants survivants d’une tumeur cérébrale de la fosse postérieure et un groupe d’enfants sains. Leur équilibre était évalué à l’aide du Bruininks-Oseretsky Test of Motor Proficiency-2nd edition (BOT-2) et du Pediatric Balance Scale (PBS). Certains participants ont aussi été évalués avec une plate-forme de force où les limites de stabilité étaient documentées. Finalement, tous les enfants et leurs parents remplissaient le Pediatric Quality of Life Inventory (PedsQL4.0). Nos résultats démontrent que les survivants présentent une diminution de l’équilibre mise en évidence par le BOT-2, mais que leur qualité de vie est similaire aux enfants sains. La performance au BOT-2 est associée à la dimension physique du PedsQL4.0, suggérant une relation entre l’équilibre et la qualité de vie. Nos résultats suggèrent qu’une évaluation de l’équilibre pourrait être bénéfique chez cette clientèle afin de mieux cerner ses besoins de réadaptation.

Hemodynamic changes during posterior epilepsies: an eeg-fnirs study

Posterior epilepsies are relatively rare, mainly suspected clinically by the presence of visual auras. Functional near-infrared spectroscopy (fNIRS) is an emerging non-invasive imaging technique that has the potential to monitor hemodynamic changes during epileptic activity. Combined with electroencephalography (EEG), 9 patients with posterior epilepsies were recorded using EEG-fNIRS with large sampling (19 EEG electrodes and over 100 fNIRS channels). Spikes and seizures were carefully marked on EEG traces, and convolved with a standard hemodynamic response function for general linear model (GLM) analysis. GLM results for seizures (in 3 patients) and spikes (7 patients) were broadly sensitive to the epileptic focus in 7/9 patients, and specific in 5/9 patients with fNIRS deoxyhemoglobin responses lateralized to the correct lobe, and to plausible locations within the occipital or parietal lobes. This work provides evidence that EEG-fNIRS is a sensitive technique for monitoring posterior epileptic activity.
