She derives stem cells from them to grow budding brain tissue harboring the secrets of his unique illness in a petri dish. She uses the information to genetically engineer a personalized treatment to correct his brain circuit functioning. Just Sci-fi? [...]

Restricting firearms access for people who misuse alcohol may prevent violence http://www.psypost.org/2015/05/restricting-firearms-access-for-people-who-misuse-alcohol-may-prevent-violence-34731 http://www.psypost.org/2015/05/restricting-firearms-access-for-people-who-misuse-alcohol-may-prevent-violence-34731#comments Sat, 30 May 2015 00:15:36 +0000 http://www.psypost.org/?p=34731 Restricting access to firearms for people who misuse alcohol could prevent firearm violence, but policies that more clearly define alcohol misuse should be developed to facilitate enforcement, according to a review of existing research and public policies by the UC Davis Violence Prevention Research Program. The analysis, published online April 30 in the peer-reviewed journal [...]

Auditory processing: Are expectations more important than sound? http://www.psypost.org/2015/05/auditory-processing-are-expectations-more-important-than-sound-34723 http://www.psypost.org/2015/05/auditory-processing-are-expectations-more-important-than-sound-34723#comments Fri, 29 May 2015 20:33:43 +0000 http://www.psypost.org/?p=34723 What affects how we hear? Do we hear sounds as they are, or do our expectations about what we are going to hear instantaneously shape the way sound is processed? These are questions that Bournemouth University’s (BU) Dr Emili Balaguer-Ballester and colleague Andre Rupp of Heidelberg University have been considering in their research into auditory [...]

Researchers ID part of the brain for processing speech http://www.psypost.org/2015/05/researchers-id-part-of-the-brain-for-processing-speech-34721 http://www.psypost.org/2015/05/researchers-id-part-of-the-brain-for-processing-speech-34721#comments Fri, 29 May 2015 20:30:54 +0000 http://www.psypost.org/?p=34721 A team of New York University neuroscientists has identified a part of the brain exclusively devoted to processing speech. Its findings point to the superior temporal sulcus (STS), located in the temporal lobe, and help settle a long-standing debate about role-specific neurological functions. “We now know there is at least one part of the brain [...]

In a paper published today in the journal Science, researchers at MIT reveal that they were able to reactivate memories that could not otherwise be retrieved, using a technology known as optogenetics. The finding answers a [...]
