#Neurons in #primate cerebral #cortex area #FEF (frontal eye fields) fire selectively when visual stimuli fall on a particular part of the #retina or when a #saccade (point-to-point eye movement) is planned and made to that location. This has an important consequence: since a saccade will bring stimuli of interest to a NEW retinal location, different cells may be firing in response to them after each eye movement. Previously, it was noticed that some cells fire in ANTICIPATION of this: if a saccade will bring a stimulus into the part of retinal space they care about, they'll fire before the saccade, even with no stimulus present in the part of retinal space they "usually" care about. This is called "predictive remapping". Now, a team at Tirin Moore's lab at #Stanford has found an even more exotic version of remapping: instead of cells firing in anticipation of a stimulus coming into their favorite part of retinal space, many neurons show a shift in preference towards the end-point of the saccade. That is, their preferred part of retinal space is pushed towards the saccade target but only just before the saccade. Very cool, and totally unclear what it means. #science #neuroscience #nature http://www.nature.com/nature/journal/v507/n7493/pdf/nature13149.pdf

As if you needed another reason to #exercise! New research in #mice suggests that aerobic exercise might guard against #AMD (age-related #macular degeneration). The disease causes late-life blindness in many humans. The research also establishes a link between exercise and light induced retinal damage / function: the molecule #BDNF (brain derived #neurotrophic factor). #science #neuroscience #jneurosci via #nytimes http://nyti.ms/1gA8Bny
