Neuroscientists discover normal brain communication in people with AgCC

Like a bridge that spans a river to connect two major metropolises, the corpus callosum is the main conduit for information flowing between the left and right hemispheres of our brains. Now, neuroscientists at the California Institute of Technology have found that people who are born without that link-a condition called agenesis of the corpus callosum, or AgCC-still show remarkably normal communication across the gap between the two halves of their brains.

New surgical tool can identify tumor margins during brain operation

Scientists are reporting development and successful initial testing of a new tool that tells whether brain tissue is normal or cancerous while an operation is underway, so that surgeons can remove more of the tumor without removing healthy tissue, improving patients' survival.

OPHN1 protein mediates mGluR-dependent longterm depression at synapses

Scientists at Cold Spring Harbor Laboratory (CSHL) have solved part of a puzzle concerning the relationship between changes in the strength of synapses - the tiny gaps across which nerve cells in the brain communicate - and dysfunctions in neural circuits that have been linked with drug addiction, mental retardation and other cognitive disorders.

New, more effective DBS paradigm may manage Parkinson's symptoms

Parkinson's disease (PD) is a devastating and incurable disease that causes abnormal poverty of movement, involuntary tremor, and lack of coordination. A technique called deep brain stimulation (DBS) is sometimes used to improve motor symptoms in patients with advanced disease. Now, a study published by Cell Press in the October 20 issue of the journal Neuron describes a new and more effective DBS paradigm that makes real-time adjustments in response to disease dynamics and progression and may be better for managing symptoms of advanced PD.
