Journal of the Royal Society, Interface / the Royal Society.J R Soc Interface.2014 Jul 6;11(96). pii: 20140318. doi: 10.1098/rsif.2014.0318.
Motor activity possesses a multiscale regulation that is characterized by fractal activity fluctuations with similar structure across a wide range of timescales spanning minutes to hours. Fractal activity patterns are disturbed in animals after ablating the master circadian pacemaker (suprachiasmati

Experimental gerontology.Exp Gerontol.2014 Jul;55:70-9. doi: 10.1016/j.exger.2014.03.011. Epub 2014 Mar 24.
Studies on the molecular clockwork during aging have been hitherto addressed to core clock genes. These previous investigations indicate that circadian profiles of core clock gene expression at an advanced age are relatively preserved in the master circadian pacemaker and the hypothalamic suprachias

Emotional modulation of attention affects time perception: Evidence from event-related potentials.

Tamm M1, Uusberg A2, Allik J3, Kreegipuu K2.
Acta psychologica.Acta Psychol (Amst).2014 Jun;149:148-56. doi: 10.1016/j.actpsy.2014.02.008. Epub 2014 Mar 18.
Emotional effects on human time perception are generally attributed to arousal speeding up or slowing down the internal clock. The aim of the present study is to investigate the less frequently considered role of attention as an alternative mediator of these effects with the help of event-related po
