As anyone suffering through a head cold knows, food tastes wrong when the nose is clogged, an experience that leads many to conclude that the sense of taste operates normally only when the olfactory system is also in good working order. Evidence that the taste system influences olfactory perception, however, has been vanishingly rare -- until now. In a novel study this week in Nature Neuroscience, Brandeis researchers report just such an influence.

 | Two new studies show that the thalamus -- the small central brain structure often characterized as a mere pit-stop for sensory information on its way to the cortex -- is heavily involved in sensory processing, and is an important conductor of the brain's complex orchestra.
Published in Nature Neuroscience and the Proceedings of the National Academy of Sciences, the two studies demonstrate the important role of the thalamus in shaping what humans see, hear and feel. ...> Full Article |

Brain imaging shows playing Tetris leads to a thicker cortex and may also increase brain efficiency, according to research published in the open access journal BMC Research Notes. A research team based in New Mexico is one of the first to investigate the effects of practice in the brain using two image techniques.

Practice makes perfect - or at least that's what we're told as we struggle through endless rounds of multiplication tables, goal kicks and piano scales - and it seems, based on the personal experience of many, to be true. That's why neuroscientists have been perplexed by data showing that at the level of individual synapses, or connections between neurons, increased, repetitive stimulation might actually reverse early gains in synaptic strength. Now, neuroscientists from Carnegie Mellon University and the Max Planck Institute have discovered the mechanism that resolves this apparent paradox. The findings are published in the Jan. 4 issue of Science.
