Enkephalin-containing interneurons are specialized to innervate other interneurons in the hippocampal CA1 region of the rat and guinea-pig

1998

Enkephalins are known to have a profound effect on hippocampal inhibition, but the possible endogenous source of these neuropeptides, and their relationship to inhibitory interneurons is still to be identified. In the present study we analysed the morphological characteristics of met-enkephalin-immunoreactive cells in the CA1 region of the rat and guinea-pig hippocampus, their coexistence with other neuronal markers and their target selectivity at the light and electron microscopic levels.  Several interneurons in all subfields of the hippocampus were found to be immunoreactive for met-enkephalin. In the guinea-pig, fibres arising from immunoreactive interneurons were seen to form a plexus …

Netiešās asociācijas sabiedrībā: salīdzinājums starp Ziemeļvalstīm un Baltijas valstīm NB6 ietvarā

2021

Šī maģistra darba tēma ir Netiešās asociācijas sabiedrībā: salīdzinājums starp Ziemeļvalstīm un Baltijas valstīm NB6 ietvarā, un tā gaitā analizētas netiešās asociācijas un to ietekmējošie faktori pret personām ar invaliditāti, sievietēm un seksuālajām minoritātēm Baltijas valstīs un Ziemeļvalstīs. Teorētiskajā ietvarā ir apkopota informācija par netiešo asociāciju konceptu, kā arī to formēšanās ietekmējošajiem faktoriem. Datu ievākšanas nolūkiem tika izveidota platforma www.HiddenBias.eu ar netiešo asociāciju testu. Darbā tika izvirzītas hipotēzes, ka Baltijas valstīs, salīdzinot ar Ziemeļvalstīm, ir novērojams ciešāks netiešo asociāciju līmenis pret visām pētāmajām grupām, un ka Baltijas …

Transcranial Magnetic Stimulation and Neuroimaging Coregistration

2013

The development of neuroimaging techniques is one of the most impressive advancements in neuroscience. The main reason for the widespread use of these instruments lies in their capacity to provide an accurate description of neural activity during a cognitive process or during rest. This important advancement is related to the possibility to selectively detect changes of neuronal activity in space and time by means of different biological markers. Specifically, functional magnetic resonance imaging (fMRI), positron emission tomography (PET), single-photon emission computed tomography (SPECT), and nearinfrared spectroscopy (NIRS) use metabolic markers of ongoing neuronal activity to provide a…

Device For Ultrasound Tests

2015

A device (1) for ultrasound tests, comprising one or more transducers (4) for generating ultrasound beams with different powers and/or frequencies to be projected in direction of a plurality of targets (11), guaranteeing the separate control of the temperature both of the targets and of the transducers and it allows performing several tests contemporarily, by optimizing the functionality and the efficiency of the device, at the same time by guaranteeing results comparable therebetween for each test, and to this purpose it comprises: a first supporting structure (3) having at least a closed chamber (7; 23) receiving the body of said one or more transducers (4) and it is isolated from a propa…

Oltre le parole: le relazioni intersoggettive nei nidi d’infanzia e la formazione delle educatrici

2017

In questo articolo mi soffermo in particolare, sulle interazioni e sui legami affettivi ed emotivi tra adulti e bambini, ma anche tra bambini e bambini, all'interno dei nidi d'infanzia, focalizzandomi sulla intercorporeità. Farò riferimento in particolare alle prospettive dell’infant research, dell’intersoggettività e delle neuroscienze secondo un “approccio in seconda persona”. Concluderò con una riflessione sulla formazione degli educatori per l’infanzia alla luce di quanto sostenuto, sottolineando la necessità di percorsi specifici e adeguati alla delicatezza ed alla complessità del ruolo svolto nella crescita dei bambini.

ILS – ett nytt finlandssvenskt material för kartläggning av läsning och skrivning

2019

Det har inte funnits tillräckligt med forskningsbaserade verktyg för kartläggning av finlandssvenska barns inlärningsmässiga och språkliga svårigheter. I samarbete mellan ILS-projektet vid Niilo Mäki Institutet och Åbo Akademi, normerades två benämningstest för finlandssvenska barn i åldern 6–12 år. Med hjälp av testen kan man både kartlägga och följa upp benämningsförmågan, men även planera olika stödinsatser. SSB – Test i Snabb Seriell Benämning mäter benämningshastigheten och antalet benämningsfel när olika stimuli presenteras i ordningsföljd. VBT – Verbbenämningstestet å sin sida mäter noggrannheten gällande benämning av enskilda bilder som föreställer olika slags handlingar. I den här …

Comparison of oxidoreductive enzyme activities in three coal tar creosote-contaminated soils

2019

This study used laboratory experiments to compare the effects of coal tar creosote on the activity of oxidoreductive enzymes in sandy loam, loamy sand and sandy clay loam soils. Different amounts of coal tar creosote were added to soil samples as follows: 0 (control), 2, 10 or 50 g kg–1 dry matter. The activity of soil dehydrogenases (DHAs), o-diphenol oxidase (o-DPO), catalase (CAT), nitrate reductase (NR) and peroxidases (POX) was determined. Contamination of soil with coal tar creosote affected oxidoreductase activity. Oxidoreductive enzyme activity following soil contamination with coal tar creosote was in the following order: DHAs > CAT > NR > POX > o-DPO in…

Tasapainon ja toimintakyvyn välinen yhteys nivelreumaa sairastavilla naisilla : seurantatutkimus

2013

Tausta ja tarkoitus: On yleisesti tunnettu tosiasia, että nivelreumaa sairastavien tasapaino on heikentynyt. He näyttäisivät luottavan tasapainon hallinnassa normaalia enemmän visuaaliseen informaatioon, kokevat enemmän tasapainon epävarmuutta ja kaatumisen pelkoa sekä heillä on kohonnut riski kaatumisiin verrattuna terveisiin verrokkeihin. Tämän Pro-gradu tutkielman tarkoituksena oli selvittää onko nivelreumaa sairastavien naisten tasapainossa eroa verrattuna terveisiin naisiin, tapahtuuko tasapainossa nivelreumaa sairastavilla ja terveillä verrokeilla muutoksia kuuden kuukauden seurannan aikana sekä onko nivelreumaa sairastavilla tasapainossa tapahtuvien muutosten ja itse arvioidussa toim…

Impact of pharmacological and environmental manipulations on neuronal structural plasticity and dynamics

2017

El sistema nervioso de vertebrados es uno de los más estudiados, aunque peor comprendidos, del organismo de mamíferos. Desde que Ramón y Cajal postuló su teoría celular de este sistema (Ramón y Cajal 1909), la neurona se ha postulado como su unidad funcional. Sin embargo, durante las últimas décadas se ha revolucionado la visión que se tenía de éste. Una de las percepciones más asentadas era que, tras el desarrollo embrionario, el sistema nervioso se mantenía inmutable. Sin embargo, ahora sabemos que diferentes formas de plasticidad gobiernan su adaptación, que son necesarias para importantes procesos del día a día, tales como el aprendizaje y la memoria (Smythies 2002; Berlucchi and Buchte…
