Atypical brain circuits may cause slower gaze shifting in infants who later develop autism

Atypical brain circuits may cause slower gaze shifting in infants who later develop autism | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it
Infants at 7 months of age who go on to develop autism are slower to reorient their gaze and attention from one object to another when compared to 7-month-olds who do not develop autism, and this behavioral pattern is in part explained by atypical...

Brain spikes: Synchrony may be key to cracking brain's neural code

Brain spikes: Synchrony may be key to cracking brain's neural code | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it

In a perspective article published in the journal Nature Neuroscience on Feb. 25, 2013, biomedical engineering professor Garrett Stanley detailed research progress toward "reading and writing the neural code." This encompasses the ability to observe the spiking activity of neurons in response to outside stimuli and make clear predictions about what is being seen, heard, or felt, and the ability to artificially introduce activity within the brain that enables someone to see, hear, or feel something that is not experienced naturally through sensory organs.(...) - Science Dailay, March 12, 2013tti

Depression stems from miscommunication between brain cells; Study challenges role of serotonin in depression | Brain Imaging and Neuroscience: The Good, The Bad, & The Ugly | Scoop.it
A new study suggests that depression results from a disturbance in the ability of brain cells to communicate with each other. The study indicates a major shift in our understanding of how depression is caused and how it should be treated.

Donald J Bolger's insight:

Overstatement... There are papers that focus on small nuclei which know not to use smoothing, and then there are papers that do whole brain analysis which report all of the regions in which "activation" was found.
