As described in Neuroscience News, Doby Rahnev, recently a member of the D'Esposito Lab but now an assistant professor at Georgia Tech, and his D'Esposito Lab colleagues have come up with a rough map of the frontal cortex’s role in controlling vision in a new paper in PNAS.
Walker Lab's latest research looks at sleep and its effects on Alzheimer's disease, as described in this article from the UC Berkeley News Center.
September, 2014: David Feinberg was awarded one of the first BRAIN Initiative grants, $1.4 million over three years from NIMH to increase the detail or spatial resolution of MRI.
Jack Gallant's work on decoding is a central part of this Nature News Feature entitled Brain decoding: Reading minds.
Sleep deprivation linked to junk food cravings. A sleepless night makes us more likely to reach for doughnuts or pizza than for whole grains and leafy green vegetables, suggests a new study from UC Berkeley that examines the brain regions that control food choices. The findings shed new light on the link between poor sleep and obesity.
Tired and edgy? Sleep deprivation boosts anticipatory anxiety. Matt Walker's lab used fMRI to study the brain's response to emotionally neutral or disturbing images, following a full night's sleep or following a sleepless night. Sleep deprivation tended to enhance the anxiety of those individuals who were innately anxious to begin with.
Wresting new tricks from a Python: Fernando Perez wins 2012 award for the advancement of free software. A physicist and applied mathematician by training, Pérez is now a research scientist at UC Berkeley’s Henry H. Wheeler Jr. Brain Imaging Center, where today he works at the interface between building scientific computing tools and the mathematical questions that arise in the analysis of brain imaging data.
Lost your keys? Your cat? The brain can rapidly mobilize a search party - Gallant Lab research shows how the brain's semantic space changes depending upon the categories of visual searches. You can also watch a video explanation of their results.
Poor sleep in old age prevents the brain from storing memories - Latest research from Matt Walker's lab, which also got some coverage in the Health section of the New York Times and in an article, "Remember, remember" in The Economist.
Increased functional selectivity over development in rostrolateral prefrontal cortex - This study reveals a pattern of increasing functional specialization within rostrolateral prefrontal cortex (RLPFC) and the inferior parietal lobe (IPL) for second-order relational processing, across 85 children aged 7-18. In addition, examination of cortical thickness reveals that local cortical thinning does not drive this pattern of increasing specialization; however, cortical thinning in IPL does appear to have some affect on functional specialization of RLPFC.

Rostrolateral prefrontal cortex: Domain-general or domain-sensitive? - Examining fMRI data from young adults as they performed separate semantic and visuospatial relational matching tasks, we were able to show that rostrolateral prefrontal cortex (RLPFC) is engaged for second-order processing in both the semantic and visuospatial domains. Although there was considerable overlap in semantic and visuospatial activations, the peaks associated with visuospatial processing, within RLPFC, were consistently superior to those associated with semantic processing.
