A team at CSHL for the 1st time reveals the birth timing and embryonic origin of a critical class of inhibitory brain cells called chandelier cells, tracing the specific paths they take during early development into the cerebral cortex of the mouse brain. The work sheds light on the genetically programed, or "nature" part of the nature/nurture question of human development. http://medicalxpress.com/news/2012-11-birth-migration-mysteries-cortex-powerful.html Neuroscience Thu, 22 Nov 2012 14:00:02 EST news272810455 As is true of many brain structures, the hippocampus, which plays a central role in memory and learning, is made up of multiple cell types organized into domains controlling different functions. Distinct from many other brain regions, however, the hippocampus is a site of active neuronal generation in the adult. Its distinctive pyramidal neurons are contained mainly in the cornu ammonis (CA), while another hippocampal region called the dentate gyrus (DG) is characterized by granule cells. While it is known that the survival of these granule cells relies on the activity of specific transcription factors, how they arise during the differentiation of the hippocampus has remained unknown. http://medicalxpress.com/news/2012-10-transcription-factor-prox1-hippocampal-cellular.html Neuroscience Tue, 16 Oct 2012 08:55:14 EST news269596504 Researchers at Cold Spring Harbor Laboratory (CSHL) have solved an important piece of one of neuroscience's outstanding puzzles: how progenitor cells in the developing mammalian brain reproduce themselves while also giving birth to neurons that will populate the emerging cerebral cortex, the seat of cognition and executive function in the mature brain. http://medicalxpress.com/news/2012-09-protein-key-fate-decision-cortical.html Neuroscience Fri, 21 Sep 2012 13:05:30 EST news267451518 New connections between brain cells emerge in clusters in the brain as animals learn to perform a new task, according to a study published in Nature on February 19 (advance online publication). Led by researchers at the University of California, Santa Cruz, the study reveals details of how brain circuits are rewired during the formation of new motor memories. http://medicalxpress.com/news/2012-02-brain-cells-clusters.html Neuroscience Sun, 19 Feb 2012 13:00:15 EST news248869230 A team of physicians and scientists at Barrow Neurological Institute, in collaboration with colleagues in the Ukraine, have written a first-of-its-kind biography of Ukranian anatomist and histologist Vladimir Betz. The article, "The Discovery of the Pyramidal Neurons: Vladimir Betz and a New Era of Neuroscience," appears in the November 2011 issue of the medical journal, Brain. http://medicalxpress.com/news/2011-12-barrow-physicians-chronicle-vladimir-betz.html Other Thu, 08 Dec 2011 10:01:53 EST news242560480
