Autism Blog - Autism: Is it all about bigger brains? « Left Brain/Right Brain
Basic Fibroblast Growth Factor (bFGF or FGF2) has particularly important implications in autism given its involvement in prolonging the period of cell division of the number of undifferentiated radial glial cells (cortical stem cells) which determine the total number of eventual minicolumns: the longer these radial glial divide, the greater the number of minicolumns, like that seen in autism.
-
in light of the increased cranial volumn and minicolumnar density in autism, more recent studies have begun targeting certain proteins and steroids called Growth Factors, which are in part intimately involved in neocortical expansion.

Scientists at UC Santa Barbara have made a major discovery in how the brain encodes memories. The finding, published in the December 24 issue of the journal Neuron, could eventually lead to the development of new drugs to aid memory.
Inside the Mind of a Savant: Scientific American
Article about Kim Peek and mind of savant.
-
Theory guides us in one respect. Kim’s brain shows abnormalities in the left hemisphere, a pattern found in many savants. What is more, left hemisphere damage has been invoked as an explanation of why males are much more likely than females to display not only savantism but also dyslexia, stuttering, delayed speech, and autism.
-
The proposed mechanism has two parts: male fetuses have a higher level of circulating testosterone, which can be toxic to developing brain tissue; and the left hemisphere develops more slowly than the right and therefore remains vulnerable for a longer period. Also supporting the role of left hemisphere damage are the many reported cases of “acquired savant syndrome,” in which older children and adults suddenly develop savant skills after damage to the left hemisphere.

Brain Stimulant: Brain Chip to Restore Functioning from Damage
The ReNaChip project is developing electronic biomimetic technology that could serve to replace damaged or missing brain tissue. This is basically neuromorphic engineering that seeks to mimic how neurons function. In the future this may be useful for people who have had injuries due to stroke or other illnesses.

-
The objective of this project is to develop a full biohybrid rehabilitation and substitution methodology; replacing the aged cerebellar brain circuit with a biomimetic chip bidirectionally interfaced to the inputs and outputs of the system. Information processing will interface with the cerebellum to actuate a normal, real-time functional behavioural recovery, providing a proof-of-concept test for the functional rehabilitation of more complex neuronal systems.

Music Improves Brain Function | LiveScience
Even a year or two of music training leads to enhanced levels of memory and attention when measured by the same type of tests that monitor electrical and magnetic impulses in the brain.
-
Laurel Trainor, director of the Institute for Music and the Mind at
McMaster University in West Hamilton, Ontario, and colleagues compared
preschool children who had taken music lessons with those who did not.
Those with some training showed larger brain responses on a number of
sound recognition tests given to the children. Her research indicated
that musical training appears to modify the brain's auditory cortex. -

Does Vitamin D Improve Brain Function?: Scientific American
And although vitamin D is well known for promoting bone health and regulating vital calcium levels—hence its addition to milk—it does more than that. Scientists have now linked this fat-soluble nutrient’s hormonelike activity to a number of functions throughout the body, including the workings of the brain.

New Light On Nature Of Broca's Area: Rare Procedure Documents How Human Brain Computes Language
"Two central mysteries of human brain function are addressed in this study: one, the way in which higher cognitive processes such as language are implemented in the brain and, two, the nature of what is perhaps the best-known region of the cerebral cortex, called Broca's area," said first author Ned T. Sahin, PhD, post-doctoral fellow in the UCSD Department of Radiology and Harvard University Department of Psychology.
-
The study – which provides a picture of language processing in the brain with unprecedented clarity – will be published in the October 16 issue of the journal Science.

Wires Inserted Into Human Brain Reveal Speech Surprise | Wired Science | Wired.com
This tested only one type of verbal cognition, cautioned Sahin, and the focus was unavoidably narrow, but it was enough to show that Broca’s area is involved not only in translating speech, but receiving it. That role was considered specific to part of the brain called Wernicke’s area.
More broadly, the findings may represent a general rule for Broca’s area, and perhaps other brain regions: Each part plays multiple roles, rather than performing a single task.
-
in’s team benefited from a brain-reading technology called intra-cranial electrophysiology, or ICE, in which electrodes are positioned inside the brain itself. It’s a medical rather than a research tool, used to precisely measure electrical activity in the brains of epileptics who don’t respond to treatment.

Reading, E-Books and the Brain : The Frontal Cortex
Although scientists had previously assumed that the dorsal route ceased to be active once we learned how to read, Deheane's research demonstrates that even literate adults still rely, in some situations, on the same patterns of brain activity as a first-grader, carefully sounding out the syllables.

This research suggests that the act of reading observes a gradient of fluency. Familiar sentences printed in Helvetica activate the ventral route, while difficult prose filled with jargon and fancy words and printed in an illegible font require us to use the slow dorsal route.
