Imaging pinpoints brain regions that 'see the future'

...om neural networks responsible for the storage and retrieval of autobiographical memories. Conversely, the neural networks associated with personal mental time travel showed significantly less activity when participants imagined scenarios involving Bill Clinton. The reason, researchers suggest, is that par...

Multi-million pound UK Biobank underway

...stems for blood sample separation and for storage, retrieval and tracking of around 10 million biological samples, which must be kept at between -80?C and -200?C for several decades. When UK Biobank is running nationwide, this robotic system will need to handle samples taken from around 1,000 people every day....

Tracking the memory trace

... formation follows a dynamic pattern, allowing for retrieval from different areas of the brain, depending on when an organism needs to remember, said a researcher at Baylor College of Medicine. That is what Dr. Ron L. Davis, professor of molecular and cellular biology at BCM, theorizes, based on his most rece...

Researchers know what you were about to say; fMRI used to detect memory storage and retrieval

...s completely," Polyn said. "In that sense, memory retrieval is like revisiting the past; brain patterns that are long gone can be revived by the memory system." ...

Researchers develop new method for studying 'mental time travel'

...the pictures. This supports the theory that memory retrieval is a form of mental time travel. In addition, by measuring second-by-second changes in how well participants were recapturing their previous brain state, the researchers were able to predict what kind of item the subjects would recall next, several ...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

...cherche Scientifique (CNRS) have been studying the retrieval of nitrogen dioxide variability from space and modelling its global behaviour. The team have published an article in the 1 September 2005 edition of the science journal Nature about the global changes in nitrogen dioxide observed in the last decad...

New research puts a fresh spin on current thinking of speech evolution in humans

...immediately in front of it that is involved in the retrieval of information from memory. "These connections suggest to us that Broca's area is in a unique position to use information shared from past experience and which is stored in memory for the service of communicative acts," explains Dr. Petrides. "That ...
