University of Utah School of Medicine researchers and their colleagues at University of Texas (UT) Southwestern Medical Center have found strong evidence that abnormal calcium signaling in neurons may play an important role in the development of spinocerebellar ataxia type 2 (SCA2), a disorder causing progressive loss of coordination, speech difficulty, and abnormal eye movements. Their findings are published in the July 27, 2009 issue of Journal of Neuroscience.SCA2 is an inherited...

John's Hopkins researchers have shown that interactions between the PICK1 protein and another group of proteins known as AMPA receptors are important for allowing certain nerve cells to learn. These nerve cells, called Purkinje cells, become desensitized in response to signals from neighboring cells in a process known as long-term depression (LTD.). It is this process that allows them to learn certain motor skills such as the vestibulo-ocular reflex which coordinates eye movements with head...

The ability of the brain to transmit and process information requires a lifelong commitment to maintaining the integrity of synapses--the special connections that permit the passage of nerve impulses from one nerve cell to another, according to investigators at St. Jude Children's Research Hospital and colleagues in Hokkaido University School of Medicine (Japan). A report on this work appears in the November 15 issue of Nature Neuroscience. This long-term commitment requires proteins called...

While researchers have long known the genetic defect underlying Fragile X syndrome, they are still tracing how that defect creates the complex mix of mental retardation, hyperactive behavior, attention deficits, and other problems in the disorder. Fragile X is particularly important because it is the most common single-gene cause of mental retardation--affecting about 1 in 4000 males and 1 in 8000 females in the U.S. In an article in the August 4, 2005, issue of Neuron, researchers led by...

The cerebellum is a section of the brain that is most in charge of cognitive functions and motor skills. Formation and Orientation The cerebellum can be found at the bottom of the brain behind the pons and below that cerebral cortex under a layer of dura mater. It is considered as a part of the "hindbrain". The cerebellum is anatomically divided into two separate hemispheres, marked by the 'vermis', a small midline zone between the left and right hemispheres. But three lobes can be...
