new paper: rehearsal initiates systems memory consolidation, sleep makes it last
April, 24th 2019
Our new paper “Rehearsl initiates systems memory consolidation, sleep makes it last” was just published in Science Advances. Using fMRI, we show how rehearsal shifts mnemonic processing from the hippocampus to the posterior parietal cortex and how sleep stabilizes this transition.
new paper: fast track to the neocortex – a memory engram in posterior parietal cortex
November, 20th 2018
Our new paper “Fast track to the neocortex: A memory engram in posterior parietal cortex” was just published in Science. We show with diffusion-weighted MRI that plasticity develops rapidly – after just one learning session – for a declarative object-location task in the precuneus. This rapid plasticity drove correct memory recall; and it persisted for more than 12 h.
new paper: inclubation, not sleep, aids problem-solving
October, 1st 2018
Our new paper “Incubation, not sleep, aids problem-solving” was just published in Sleep.
In this paper, we try to tease apart the effects of sleep and inclubation on problem-solving in different tasks: classic riddles,visual change detection and anagrams.
new paper: how subclasses affect classification
September, 27th 2018
Our new paper “Multivariate classification of neuroimaging data with nested subclasses: Biased accuracy and implications for hypothesis testing” was just published in PLOS Computational Biology.
In this paper, we show how subclasses can bias classification results and inflate correct classification rates of linear classifiers. We show, when this bias is strongest and how to use permutation tests to correct this bias.
meet us and discuss our new MEG sleep results at ESRS in Basel
September, 23rd 2018
Steffen and Lea will be attending ESRS in Basel from the 25th to the 28th of September.
Lea will be presenting a poster on her newest MEG results on October, 26th from 11:00 to 13:00 (P033).
Come find us and discuss slow oscillations, sleep spindles and why recording sleep in the MEG is fascinating.
