Blindness is a world wide problem. As of 2012 there were 285 million visually impaired people in the world, of which 246 million had low vision and 39 million were blind. Most people with poor vision are in the developing […]

 
Sensations which seem to come from limbs that had been amputated are called «phantoms». Most limb amputees report awareness of a phantom limb, i.e., the perceived presence of the missing arm or leg. Phantom sensations may also occur after […]

As we saw in the previous entry of this series, philosophers of mind usually distinguish between what (after David Chalmers) they called the ‘easy’ and the ‘hard’ problem of consciousness. The ‘easy’ problem refers to how to explain the functioning […]

Some jellyfish species are beautifully fluorescent in the dark ocean, emitting light from different parts of their bodies in a process that is thought to help them to warn off predators. The molecular biology behind this process of […]

 
People, like cats, are curiosity-driven creatures that manifest unique inclinations towards certain stimuli. Curiosity´s unavoidability has been immortalized in the proverb of the cat. Could we be so extremely pulled by this impulse to the level of […]

Alzheimer’s disease (AD) is one of the most devastating human pathologies. AD is the leading cause of age-related dementia and currently afflicts more than 44 million persons worldwide (World Alzheimer Report 2014). It is characterized by a cognitive […]

The study of the spontaneous activity in the brain –and its origin– is one of the major puzzles in modern neural science. In many situations, the same neurons which behave smoothly and in an easily predictable way in in vitro […]
