Recent reports have suggested that patients with semantic dementia show a loss of early (remote) auto-biographical memories with pronounced sparing of recent memories (Graham & Hodges, 1997; Snowden, Griffiths, & Neary, 1996), i.e., a 'reversed' temporal gradient or 'Ribot effect'. At first sight, these findings suggest that the deficits in 'semantic' dementia go beyond the semantic domain, inv...

How an animal learns, remembers, and uses information to guide adaptive behavior remains one of the most challenging questions in science today. Much progress was made in the twentieth century, and new tools available to neurobiological investigators have accelerated progress in the new century. Nevertheless, the road has been rocky and progress sometimes impeded by periodic polemic debates at ...

How learning and memory is achieved in the brain is a central question in neuroscience. Key to today's research into information storage in the brain is the concept of synaptic plasticity, a notion that has been heavily influenced by Hebb's (1949) postulate. Hebb conjectured that repeatedly and persistently co-active cells should increase connective strength among populations of interconnected ...

Since the discovery and description of first specialized cave species, subterranean fauna stimulated scientific research several generations speleobiologists especially after publication Racovitza's classification which is still used today, amended for non-karstic areas groundwaters. More than 28,000 obligate species are known worldwide; however, these figures likely to be underestimated since ...

It is not uncommon for emeritus professors to take a more reflective view of their discipline, or even for them to grapple with the significance of their specialist knowledge for perennial human questions. Leslie Hearnshaw, for many years Professor of Psychology at Liverpool, is better equipped than many for this role, having already written a history of British psychology and the standard biog...
