Bevandic J, Stella F, Olafsdottir H
Curr Biol
. 2024 Sep;
34(21):5062-5072.e5.
PMID: 39305898
Hippocampal-dependent memory is known to emerge late in ontogeny, and its full development is protracted. Yet the changes in hippocampal neuronal function that underlie this delayed and gradual maturation remain...

Neuron
. 2024 Feb;
112(7):1060-1080.
PMID: 38359826
Human episodic memory is not functionally evident until about 2 years of age and continues to develop into the school years. Behavioral studies have elucidated this developmental timeline and its...

Science
. 2023 Oct;
382(6668):262-263.
PMID: 37856580
Hierarchical organization of memory is observed in the brains of rats.

Santos-Pata D, Barry C, Olafsdottir H
Curr Biol
. 2023 Sep;
33(21):4570-4581.e5.
PMID: 37776862
Precisely timed interactions between hippocampal and cortical neurons during replay epochs are thought to support learning. Indeed, research has shown that replay is associated with heightened hippocampal-cortical synchrony. Yet many...

Ambrogioni L, Olafsdottir H
Trends Cogn Sci
. 2023 Jun;
27(8):702-712.
PMID: 37357064
A hallmark of biological intelligence is the ability to adaptively draw on past experience to guide behaviour under novel situations. Yet, the neurobiological principles that underlie this form of meta-learning...

Bush D, Olafsdottir H, Barry C, Burgess N
Curr Biol
. 2021 Nov;
32(1):64-73.e5.
PMID: 34731677
Neuronal "replay," in which place cell firing during rest recapitulates recently experienced trajectories, is thought to mediate the transmission of information from hippocampus to neocortex, but the mechanism for this...

Liu Y, Dolan R, Higgins C, Penagos H, Woolrich M, Olafsdottir H, et al.
Elife
. 2021 Jun;

PMID: 34096501
There are rich structures in off-task neural activity which are hypothesized to reflect fundamental computations across a broad spectrum of cognitive functions. Here, we develop an analysis toolkit - temporal...

Bevandic J, Genzel L, Olafsdottir H
Neuron
. 2021 Mar;
109(6):913-915.
PMID: 33735613
In this issue of Neuron, McKenzie et al. (2021) test the degree to which pre-existing biases in hippocampal circuits constrict the encoding of new information via artificial induction of place...

Peron S, Pancholi R, Voelcker B, Wittenbach J, Olafsdottir H, Freeman J, et al.
Nature
. 2020 Mar;
579(7798):256-259.
PMID: 32132709
Most cortical synapses are local and excitatory. Local recurrent circuits could implement amplification, allowing pattern completion and other computations. Cortical circuits contain subnetworks that consist of neurons with similar receptive...

PLoS Comput Biol
. 2019 Feb;
15(2):e1006822.
PMID: 30768590
Place cells in the mammalian hippocampus signal self-location with sparse spatially stable firing fields. Based on observation of place cell activity it is possible to accurately decode an animal's location....
