R. S. Liu, L. Lemieux, G. S. Bell, S. M. Sisodiya, S. D. Shorvon, J. W. Sander, J. S. Duncan Institute of Neurology, London, London, United Kingdom Synopsis Whether cerebral damage results from epileptic seizures remains a contentious issue. We report on the first longitudinal community-based quantitative MRI study to investigate the effect of seizures on the hippocampus, cerebellum and neocort...

R. S. Liu, L. Lemieux, A. Hammers, G. S. Bell, S. M. Sisodiya, S. D. Shorvon, J. W. Sander, J. S. Duncan Institute of Neurology, London, London, United Kingdom Synopsis We investigated the pattern of generalized and focal neocortical atrophy that develops in patients with epilepsy. Patients and controls were scanned 3.5 years apart. Image subtraction was used to identify neocortical change that...

Tracking the movement of animals is one most important methods used by scientists to study animal behaviour. Before arrival modern technologies, researchers measured locomotion simply observing and describing it in objective way possible (Kline, 1899). The use cameras computers brought new tools researchers, allowing an easier, faster more measuring A growing number video tracking programs allo...

Are people who are funny more attractive? Or does being attractive lead people to be seen as funnier? The answer may depend on the underlying evolutionary function of humor. While humor has been proposed to signal “good genes,” we propose that humor also functions to indicate interest in social relationships – in initiating new relationships and in monitoring existing ones. Consistent with this...

This work deals with the H1 condition numbers and the distribution of the ~ N;Msingular values of the preconditioned operators f~ 1 N;M WN;M ÂN;Mg. ÂN;M is the matrix representation of the Legendre Spectral Collocation discretization of the elliptic operator A de ned by Au := u + a1ux + a2uy + a0u in (the unit square) with boundary conditions: u = 0 on 0; @u @ A = u on 1. ~ N;M is the sti ness ...
