Neural Stem Cells Regenerate Axons in Severe Spinal Cord Injury

Researchers were able to regenerate an astonishing degree of axonal growth at the site of severe spinal cord injury in rats. Results were then replicated using two human stem cell lines, one already in human trials for ALS. “We obtained the exact results using human cells as we had in the rat cells,” said Tuszynski.

Her Vision is 20/20, But She Can’t Make Sense of What She Sees

A rare and baffling neurological disorder called Bálint syndrome, which badly impairs a patient's ability to make sense of what he or she sees is discussed. The article describes, in novelistic detail, the difficult adjustments two patients have had to make in their lives.

Researchers Create Short-Term Memories In-Vitro

Researchers have discovered how to store diverse forms of artificial short-term memories in isolated brain tissue. Using isolated pieces of rodent brain tissue, the researchers demonstrated that they could form a memory of which one of four input pathways was activated.

Astrocytes Control the Generation of New Neurons from Neural Stem Cells

Neuroscience researchers show how astrocytes control the generation of new neurons in the brain. “In the brain, astrocytes control how many new neurons are formed from neural stem cells and survive to integrate into the existing neuronal networks. Astrocytes do this by secreting specific molecules but also by much less understood direct cell-cell interactions with stem cells”, says Prof. Milos Pekny.

One Week of Therapy May Help Reorganize Brain, Reduce Stuttering

Just one week of speech therapy may reorganize the brain, helping to reduce stuttering, according to a study published in the August 8, 2012, online issue of Neurology, the medical journal of the American Academy of Neurology.

Brain’s Stem Cells Eavesdrop to Find Out When to Act

Working with mice, Johns Hopkins researchers say they have figured out how stem cells found in a part of the brain responsible for learning, memory and mood regulation decide to remain dormant or create new brain cells. Apparently, the stem cells “listen in” on the chemical communication among nearby neurons to get an idea about what is stressing the system and when they need to act.

Neurons Derived from Cord Blood Cells May Represent New Therapeutic Option

The researchers demonstrated that cord blood cells, which come from the mesoderm, the middle layer of embryonic germ cells, can be switched to ectodermal cells, outer layer cells from which brain, spinal and nerve cells arise. "This study shows for the first time the direct conversion of a pure population of human cord blood cells into cells of neuronal lineage by the forced expression of a single transcription factor," says Juan Carlos Izpisua Belmonte.

Study Shows the Deaf Brain Processes Touch Differently

Lacking sound input, the primary auditory cortex “feels” touch. The finding reveals how the early loss of a sense affects brain development. It adds to a growing list of discoveries that confirm the impact of experiences and outside influences in molding the developing brain.
