Chronic nicotine reverses working memory deficits caused by lesions of the fimbria or medial basalocortical projection / Edward D. LEVIN in Cognitive Brain Research, 1-3 (October 1993)

Public ISBD [article]  inCognitive Brain Research > 1-3 (October 1993) . - p.137-143 Titre : Chronic nicotine reverses working memory deficits caused by lesions of the fimbria or medial basalocortical projection Type de document : Texte imprimé et/ou numérique Auteurs : Edward D. LEVIN, Auteur ; N. Channelle CHRISTOPHER, Auteur ; Sandra J. BRIGGS, Auteur ; Jed E. ROSE, Auteur Année de publication : 1993 Article en page(s) : p.137-143 Langues : Anglais (eng) Mots-clés : Nicotine Chronic Lesion Fimbria Basalocortical-projection Memory Nicotinic-acetycholine Radial-arm-maze Index. décimale : PER Périodiques Résumé : Nicotine has been found in a variety of studies to improve performance in memory tasks. This study was conducted to determine if chronic nicotine administration is useful in counteracting the working memory deficits seen after lesions of the fimbria or the medial basalocortical projection. Rats were trained to asymptotic performance on a working memory version of the radial-arm maze. Then, they were given knife cut lesions of the fimbria or the medial basalocortical projection or underwent sham surgeries. At the time of surgery, rats in each treatment group were implanted with either nicotine-containing or placebo glass and Silastic pellets. Rats with fimbria or basalocortical lesions showed a significant decline in working memory performance. Chronic nicotine significantly improved choice accuracy in both lesioned and unlesioned rats. Nicotine treatment restored performance of the lesioned rats to control levels. These data show that in addition to improving memory performance in normal rats, nicotine can counteract lesion-induced memory impairments. Nicotine also may be useful for treatment of disease-related memory impairments such as seen in Alzheimer's disease.

Topographic differences of slow event-related brain potentials in blind and sighted adult human subjects during haptic mental rotation / Frank ROSLER in Cognitive Brain Research, 1-3 (October 1993)

The overall topography of the slow wave pattern which prevailed during the task differed for sighted and for blind, but not for congenitally and adventitiously blind subjects. While the tactile stimuli were encoded, the blind showed a pronounced occipital and the sighted a pronounced frontal activation. The task-specific amplitude increment of a negative slow wave which can be understood as a manifestation of the process of mental rotation proper, showed a different topography for sighted and for blind subjects too. It had its maximum over central to parietal cortical areas in both groups, but it extended more towards occipital regions in the blind. In both groups, the effects were very similar to those observed in former studies with visual versions of the mental rotation task, i.e. the slow wave amplitude over central to parietal areas increased monotonously with an increasing angular disparity of the two stimuli to be compared. These results are discussed with respect to the question of whether visual deprivation in the blind can cause a reorganization of cortical representational maps.

The effects of age on the N200 component of the auditory event-related potentials / Hideo ENOKI in Cognitive Brain Research, 1-3 (October 1993)

Public ISBD [article]  inCognitive Brain Research > 1-3 (October 1993) . - p.161-167 Titre : The effects of age on the N200 component of the auditory event-related potentials Type de document : Texte imprimé et/ou numérique Auteurs : Hideo ENOKI, Auteur ; Satoshi SANADA, Auteur ; Harumi YOSHINAGA, Auteur ; Eiji OKA, Auteur ; Shunsuke OHTAHARA, Auteur Année de publication : 1993 Article en page(s) : p.161-167 Langues : Anglais (eng) Mots-clés : Event-related-potential N200 P300 Child Development Aging Index. décimale : PER Périodiques Résumé : This study was undertaken to determine the effects of development and aging on N200 of event-related potentials from childhood to adulthood. Event-related potentials were recorded from 164 normal subjects ranging in age from 4 to 77 years. A total of 127 of the 164 subjects demonstrated N200 peaks. N200 showed marked developmental changes. During childhood, the N200 latency decreased rapidly with age to the minimum (217±17.3 ms) at 16 years of age, while it was prolonged gradually with age during adulthood. The latency/age slope in the subjects from 5 to 15 years of age was -9.03 ms/year, while +0.97 ms/year in those from 16 to 77. The N200-P300 interpeak latency remained constant in all age groups and showed no age-related changes. The N200 amplitude decreased as age increased. Nineteen young cases showed N200 peaks to the frequent stimuli. Their ages ranged from 5 to 17 years. Our study suggests that N200 is valuable in evaluating the developmental and aging processes in the central nervous system. The results of this study could be used as normative data in clinical practices.

Motion-onset visual-evoked potentials as a function of retinal eccentricity in man / Ljudmila SCHLYKOWA in Cognitive Brain Research, 1-3 (October 1993)

Public ISBD [article]  inCognitive Brain Research > 1-3 (October 1993) . - p.169-174 Titre : Motion-onset visual-evoked potentials as a function of retinal eccentricity in man Type de document : Texte imprimé et/ou numérique Auteurs : Ljudmila SCHLYKOWA, Auteur ; Bob W.

The center of the 2x2 deg stimulus field was binocularly viewed either foveally or at eccentricities of 6, 12, or 20 deg in the lower visual field along the vertical meridian. Peak-to-peak amplitudes P1-N2 and N2-P2 were found to decrease non-linearly as a function of eccentricity. The VEP-amplitudes were standardized by setting each foveal value to 100%, and a relative measure was derived for peripheral values given by the ratio of the peripheral to the foveal values. The decrease of the relative VEP-values with eccentricity was significantly smaller than that of the relative cortical magnification factor of striate cortex in man, whereas it agreed fairly well with that of the relative point-image size of the area MT in Macaque monkey. In this respect, the motion-onset VEP is distinct from the pattern-reversal VEP, the amplitude of which decreases much more rapidly with retinal eccentricity; hence, it may involve different generating structures of the brain.

Here we extend these observations by a non-linear dynamical analysis of these oscillatory signals (local fields potentials) in successive epochs during background activity and visual responses. Two numerical estimates have been obtained from the original data every 200 ms: (1) correlation dimension and (2) non-linear forecasting of the trajectories. Results from eight different recording sites analyzed are consistent and indicate, in the average, an increase in complexity of the signal during the oscillatory periods.

Event-related brain potentials during natural speech processing: effects of semantic, morphological and syntactic violations / Angela D. FRIEDERICI in Cognitive Brain Research, 1-3 (October 1993)

The sentences which were presented as connected speech were either correct or incorrect including a semantic error (selectional restriction), a morphological error (verb inflection), or a syntactic error (phrase structure). After each sentence, a probe word was presented auditorily, and subjects had to decide whether this word was part of the preceding sentence or not. Event-related brain potentials (ERPs) were recorded from 7 scalp electrodes. The ERPs evoked by incorrect sentences differed significantly from the correct ones as a function of error type. Semantic anomalies evoked a ‘classical’ N400 pattern. Morphological errors elicited a pronounced negativity between 300 and 600 ms followed by late positivity. Syntactic errors, in contrast, evoked an early negativity peaking around 180 ms followed by a negativity around 400 ms. The early negativity was only significant over the left anterior electrode. The present data demonstrate that linguistic errors of different categories evoke different ERP patterns. They indicate that with using connected speech as input, different aspects of language comprehension processes cannot only be described with respect to their temporal structure, but eventually also with respect to possible brain systems subserving these processes.

Chronometrical analysis of event-related potentials and reaction time in patients with multiple lacunar infarcts / Hisao TACHIBANA in Cognitive Brain Research, 1-3 (October 1993)

The N2 and RT latencies of the patients were significantly longer than those of normal subjects, although P2 and P3 latencies did not differ between the two groups. However, the time from N2 to RT did not differ between the two groups. These observations suggest that the impairment of cognitive information processing in these patients arises from an uncertainty in classifying the perceived event, while motor organization time is relatively well preserved. In addition, the N2 latency may be more sensitive in detecting cognitive impairment in such patients.
