Chromosome 15 duplication has unpredictable brain effects

by  /  3 December 2008

The first postmortem study to examine the effects of chromosome 15 duplication on gene expression shows completely divergent results, suggesting that the effect of genetic duplications is far from predictable, according to a study published last month in the Journal of Medical Genetics.

MicroRNAs may play a role in autism, studies find

by  /  26 November 2008

Some small fragments of RNA are expressed differently in people with autism than in controls, according to two new studies. The findings unveil another layer of complexity in the genetics of autism.

Size of infant’s amygdala predicts language ability

by  /  21 November 2008

A child’s language ability correlates with the volume of his or her amygdala ― the small, deep brain region that is strongly associated with emotion processing ― according to an unpublished five-year longitudinal study presented Wednesday afternoon at the Society for Neuroscience meeting.

Beyond mirror neurons

by  /  20 November 2008

High-functioning children with autism may understand another personʼs intention when, for example, that person reaches for a glass of water ― a simple, goal-directed task ― without help from the mirror neuron system, according to research reported Tuesday at the Society for Neuroscience meeting.

Finding the right (synaptic) partners

by  /  19 November 2008

Researchers are narrowing in on a pool of genes that may be involved in helping neurons find their targets, according to unpublished work presented today in a poster session at the Society for Neuroscience meeting.

A drug that lasts for days

by  /  19 November 2008

A new slow-release form of the drug risperidone ― an antipsychotic given to people with schizophrenia, autism and other psychiatric conditions ― lasts in the blood days instead of hours, according to research presented today at the Society for Neuroscience meeting.

microRNAs in mental illness

by  /  19 November 2008

Some small fragments of RNA, called microRNAs, are under-expressed in people with schizophrenia and bipolar disorder compared with controls, according to unpublished research based on postmortem brain tissue presented this morning at the Society for Neuroscience meeting.

Pathways to plasticity

by  /  18 November 2008

The molecular mechanisms underlying synaptic plasticity ― the ability of neurons to change the strength of their connections ― can vary across different inhibitory neural circuits as much as they can vary across excitatory neural circuits, according to research presented this morning at the Society for Neuroscience meeting.

Lithium’s effect on fragile X mice

by  /  18 November 2008

Lithium treatment reverses some of the behavioral and brain-cell abnormalities in mouse models of fragile X syndrome ― an inherited form of mental retardation that includes learning deficits, aggressiveness, and social withdrawal ― according to research presented today at the Society for Neuroscience meeting.

‘Optogenetics’ sheds light on role of different neurons

by  /  18 November 2008

For decades, those who study brain cell activity have faced a fundamental trade off: either closely monitor the activity of a single cell or look at the circuit level to see how large groups of neurons communicate with each other.
