Front Psychol. 2013 Mar 18;4:116. doi: 10.3389/fpsyg.2013.00116. eCollection 2013.

This paper reports an experiment intended to test a particular hypothesis derived from blindsight research, which we name the "source misidentification hypothesis." According to this hypothesis, a subject may be correct about a stimulus without being correct about how...

Modelling migration: the clock-and-compass model can explain the distribution of ringing recoveries.

Animal behaviour

PMID: 9790701
Anim Behav. 1998 Oct;56(4):899-907. doi: 10.1006/anbe.1998.0826.

The aim of the present study was to test whether the directional distributions found in ringing recoveries could be explained if night-migrating passerines use only a simple clock-and-compass strategy during autumn migration. I developed a mathematical model that predicts...

Cryptochrome magnetoreception: four tryptophans could be better than three.

Journal of the Royal Society, Interface

Wong SY, Wei Y, Mouritsen H, Solov'yov IA, Hore PJ.

J R Soc Interface. 2021 Nov;18(184):20210601. doi: 10.1098/rsif.2021.0601. Epub 2021 Nov 10.

The biophysical mechanism of the magnetic compass sensor in migratory songbirds is thought to involve photo-induced radical pairs formed in cryptochrome (Cry) flavoproteins located in photoreceptor cells in the eyes. In Cry4a-the most likely of the six known avian...

Cryptochromes are photolyase-related blue-light receptors acting as core components of the mammalian circadian clock in the cell nuclei. One or more members of the cryptochrome protein family are also assumed to play a role in avian magnetoreception, but the...

Theophylline as an add-on to thrombolytic therapy in acute ischaemic stroke (TEA-Stroke): A randomized, double-blinded, placebo-controlled, two-centre phase II study.

European stroke journal

Modrau B, Hjort N, Østergaard L, Mouridsen K, Andersen G, Bach FW.

INTRODUCTION: Early reperfusion of brain tissue at risk of injury (penumbra salvage) is crucial in treating acute ischaemic stroke. Neuroprotective agents may extend the time window for the reperfusion. The vasoactive agent theophylline redistributes the perfusion to ischaemic brain...

Introduction. Decreased salivary flow and xerostomia are frequent findings in Parkinson's disease (PD), possibly caused by alterations in the parasympathetic tonus. Here we explore salivary acetylcholinesterase (AChE) activity as a potential biomarker in PD. Methods. We measured salivary flow,...

A robust synthesis of 7,8-didemethyl-8-hydroxy-5-deazariboflavin.

Beilstein journal of organic chemistry

Bender M, Mouritsen H, Christoffers J.
PMID: 27340481
Beilstein J Org Chem. 2016 May 06;12:912-7. doi: 10.3762/bjoc.12.89. eCollection 2016.

The biosynthetic precursor of redox cofactor F420, 7,8-didemethyl-8-hydroxy-5-deazariboflavin, was prepared in four steps from 6-chlorouracil, 2-chloro-4-hydroxybenzaldehyde and bis-isopropylidene protected D-ribose. The latter aldehyde was transformed to the corresponding protected ribitylamine via the oxime, which was submitted to reduction with...

Distinguishing between coherent and incoherent signals in excitation-emission spectroscopy.

Optics express

Lünemann DC, Thomas AR, Xu J, Bartölke R, Mouritsen H, De Sio A, Lienau C.
PMID: 34614680
Opt Express. 2021 Jul 19;29(15):24326-24337. doi: 10.1364/OE.428850.

The separation of incoherent emission signals from coherent light scattering often poses a challenge in (time-resolved) microscopy or excitation-emission spectroscopy. While in spectro-microscopy with narrowband excitation this is commonly overcome using spectral filtering, it is less straightforward when using...
