The brain forgets in order to conserve energy
Our brains not only contain learning mechanisms but also forgetting mechanisms that erase "unnecessary" learning. A research group at Lund University in Sweden has now been able to describe one of these mechanisms at the ...

Smart microchips may optimise human vision
To date, chip-based retinal implants have only permitted a rudimentary restoration of vision. However, modifying the electrical signals emitted by the implants could change that. This is the conclusion of the initial published ...

Light in sight: A step towards a potential therapy for acquired blindness
Hereditary blindness caused by a progressive degeneration of the light-sensing cells in the eye, the photoreceptors, affects millions of people worldwide. Although the light-sensing cells are lost, cells in deeper layers ...

Neither flashing traffics lights nor the colour yellow deter pedestrians from crossing
A study by scientists at the University of Granada (UGR) has shown that neither flashing traffic lights and nor the colour yellow have any effect on pedestrians. Only the two mandatory phases–steady green and steady red–are ...

Flashes of light help researchers to both 'read' and 'write' brain signals
University College London researchers have developed an innovative way to understand how the brain works by using flashes of light, allowing them to both 'read' and 'write' brain signals.

Pleasure response from chocolate: You can see it in the eyes
The brain's pleasure response to tasting food can be measured through the eyes using a common, low-cost ophthalmological tool, according to a study just published in the journal Obesity. If validated, this method could be ...
