•Using machine-learning techniques, a research team has reconstructed a short movie of small, randomly moving discs from signals produced by rat retinal neurons. …read more Source:: Science
New neurons in the adult brain are involved in sensory learning
by
•Scientists have demonstrated that the new neurons produced in adults react preferentially to reward-related sensory stimuli and help speed up the association between sensory information and reward. Adult-born neurons therefore …read more Source:: Science
Researchers invent tiny, light-powered wires to modulate brain’s electrical signals
by
•A new study shows how tiny, light-powered wires could be fashioned out of silicon to manipulate electrical signaling between neurons. The research offers a new avenue to shed light on–and …read more Source:: Science
Human skin cells transformed directly into motor neurons
by
•Scientists have converted skin cells from healthy adults directly into motor neurons without going through a stem cell state. The technique makes it possible to study motor neurons of the …read more Source:: Science
New surgical strategy offers hope for repairing spinal injuries
by
•Repairing spinal injuries is a difficult business. Scientists previously developed a new surgical technique to reconnect sensory neurons to the spinal cord after traumatic spinal injuries. Now, they have gained …read more Source:: Science
Human neurons continue to migrate after birth
by
•Researchers have discovered a previously unknown mass migration of inhibitory neurons into the brain’s frontal cortex during the first few months after birth, revealing a stage of brain development that …read more Source:: Science
