Kirker, korona og nettbaserte gudstjenester
2021
Sammendrag Store deler av Norge ble digitale da landet nærmest stengte ned våren 2020. Denne artikkelen dreier seg om hva som skjedde da kirker og menigheter byttet kirkerommet med det digitale rom som følge av korona-pandemien. Det ble holdt gudstjenester og til og med «servert» kirkekaffe på nett. Artikkelen bygger på en undersøkelse som viser at 72 % av norske kirker og menigheter produserte nettbaserte samlinger under koronakrisen. 749 kirkeledere i hele Norge har deltatt i den omfattende kartleggingen som fant sted fra 15. april til 10. mai 2020. Dette utgjør om lag en tredel av alle registrerte menigheter og kristne forsamlinger i landet. I artikkelen presenterer og diskuterer vi f…

Hippocampal theta phase-contingent memory retrieval in delay and trace eyeblink conditioning
2017
Hippocampal theta oscillations (3–12 Hz) play a prominent role in learning. It has been suggested that encoding and retrieval of memories are supported by different phases of the theta cycle. Our previous study on trace eyeblink conditioning in rabbits suggests that the timing of the conditioned stimulus (CS) in relation to theta phase affects encoding but not retrieval of the memory trace. Here, we directly tested the effects of hippocampal theta phase on memory retrieval in two experiments conducted on adult female New Zealand White rabbits. In Experiment 1, animals were trained in trace eyeblink conditioning followed by extinction, and memory retrieval was tested by presenting the CS at …

Learning to learn: Theta oscillations predict new learning, which enhances related learning and neurogenesis
2012
Animals in the natural world continuously encounter learning experiences of varying degrees of novelty. New neurons in the hippocampus are especially responsive to learning associations between novel events and more cells survive if a novel and challenging task is learned. One might wonder whether new neurons would be rescued from death upon each new learning experience or whether there is an internal control system that limits the number of cells that are retained as a function of learning. In this experiment, it was hypothesized that learning a task that was similar in content to one already learned previously would not increase cell survival. We further hypothesized that in situations in…
Hippocampal theta activity is selectively associated with contingency detection but not discrimination in rabbit discrimination-reversal eyeblink con…
2010
The relative power of the hippocampal theta-band (∼6 Hz) activity (theta ratio) is thought to reflect a distinct neural state and has been shown to affect learning rate in classical eyeblink conditioning in rabbits. We sought to determine if the theta ratio is mostly related to the detection of the contingency between the stimuli used in conditioning or also to the learning of more complex inhibitory associations when a highly demanding delay discrimination-reversal eyeblink conditioning paradigm is used. A high hippocampal theta ratio was not only associated with a fast increase in conditioned responding in general but also correlated with slow emergence of discriminative responding due to…
Breathe out and learn : Expiration-contingent stimulus presentation facilitates associative learning in trace eyeblink conditioning
2019
Rhythmic variation in heart rate and respiratory pattern are coupled in a way that optimizes the level of oxygen in the blood stream of the lungs and the body as well as saves energy in pulmonary gas exchange. It has been suggested that the cardiac cycle and respiratory pattern are coupled to neural oscillations of the brain. Yet, studies on how this rhythmic coupling is related to behavior are scarce. There is some evidence that, for example, the phase of respiration affects memory retrieval and the electrophysiological oscillatory state of the limbic system. It is also known that the phase of the cardiac cycle and hippocampal electrophysiological oscillations alone affect learning. Here, …
Asiantuntijat uusien toimintamallien oppijoina
2003
Työ muuttuu ja sitä kautta myös työssä tarvittavien toimintatapojen pitäisi muuttua. Ajattelumallien tai toimintatapojen muuttaminen ei ole aina helppoa, sillä käytössä olevat mallit rutinoituvat nopeasti. Ihmisillä ei ole kykyä, halua tai aikaa tarkastella omaa työtään uusien silmälasien läpi, arvioida tapojensa toimivuutta tai jopa kokonaan kyseenalaistaa niiden järkevyyttä. Mielenkiintoisen ratkaisun etsiä uusia toimintamalleja ennakkoluulottomasti edustaa seuraava esimerkki Englannista. – Artikkelissa kuvataan brittiläisessä sairaalassa toteutettua kehittämisprosessia, jossa lääkärien visuaalisen hahmottamisen apuna on käytetty taiteilijoita.
