When we learn, we associate a sensory experience either with other stimuli or with a certain type of behavior. The neurons in the cerebral cortex that transmit the information modify the synaptic connections that they have with the other neurons. According to a generally-accepted model of synaptic plasticity, a neuron that communicates with others of the same kind emits an electrical impulse as well as activating its synapses transiently.

Changes in ADNP gene may be among the most common causes of autism

A new study from Bradley Hospital has identified a genetic change in a recently identified autism-associated gene, which may provide further insight into the causes of autism. The study, now published online in the Journal of Medical Genetics, presents findings that likely represent a definitive clinical marker for some patients’ developmental disabilities.

Findings, published in Nature, could lead to improved treatments for stroke, other brain injuries

Learning a new skill is easier when it is related to ability that we already possess. For example, a trained pianist might learn a new melody more easily than learning how to hit a tennis serve.

The hormone erythropoietin (EPO) could prevent brain injuries in very premature babies, a study suggests.

Brain scans show EPO - used illegally by athletes to boost performance - may help infants when given after birth.

The study, published in the Journal of the American Medical Association, involved almost 500 babies born between 26 and 31 weeks in Switzerland.

The researchers are calling for wider trials of the hormone, which is already given to some babies to treat anaemia.

Erythropoietin is a hormone that stimulates production of red blood cells.

Oligodendrocyte lineage gene 1 (Olig1) plays a key role in hypoxic-ischemic brain damage and myelin repair. miRNA-9 is involved in the occurrence of many related neurological disorders. Bioinformatics analysis demonstrated that miRNA-9 complementarily, but incompletely, bound oligodendrocyte lineage gene 1, but whether miRNA-9 regulates oligodendrocyte lineage gene 1 remains poorly understood.
