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.

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or her amygdala ― the small, deep brain region that is strongly associated with emotion processing ― according to an unpublished five-year longitudinal study presented Wednesday afternoon at the Society for Neuroscience meeting.
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.
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microRNAs, are under-expressed in people with schizophrenia and bipolar disorder compared with controls, according to unpublished research based on postmortem brain tissue presented this morning at the Society for Neuroscience meeting.
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 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.
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.
