First Genetic Map Of The Cerebral Cortex Produced

The first genetic map of the cerebral cortex has been created through a major international collaboration. It identifies more than 300 genetic variants that influence the structure of the key brain region. The cerebral cortex — often referred to as the grey matter – plays a crucial role in thinking,…Continue readingFirst Genetic Map Of The Cerebral Cortex Produced

Neurogliaform Cells Form In The Brain’s Preoptic Area

Scientists from the University of Geneva (UNIGE) have discovered a unique molecular factor allowing them to track, from birth to maturity, a homogeneous class of neurons called the neurogliaform cells. The results reveal for the first time the genesis and the development of these cells, opening new opportunities for the…Continue readingNeurogliaform Cells Form In The Brain’s Preoptic Area

Brain’s Visual Circuitry Sculpted By First Sights Babies See

Scientists have found more clues about what happens in the brains of baby mammals as they try to make visual sense of the world. The study in mice is part of an ongoing project in the lab of Spencer Smith, assistant professor of cell biology and physiology at the UNC…Continue readingBrain’s Visual Circuitry Sculpted By First Sights Babies See

Visual Cortex Has Effect On Eye Movement Plasticity

The visual cortex, a region of the brain known to process sensory information, plays a key role in promoting the plasticity of innate, spontaneous eye movements, a study has found. Researchers made the unexpected discovery by peering into the eyes of mice and tracking their ocular movements. Houmam Araj, Ph.D.,…Continue readingVisual Cortex Has Effect On Eye Movement Plasticity

Anatomical Cerebral Cortex Patterning Regulated By Genetic Factors

The extraordinarily homogeneous anatomical patterning of the brain’s cortex is controlled by genetic factors, suggests a new study by an international research consortium led by Chi-Hua Chen of the University of California, San Diego, and Nicholas Schork of the J. Craig Venter Institute. The human brain’s wrinkled cerebral cortex, which…Continue readingAnatomical Cerebral Cortex Patterning Regulated By Genetic Factors

Thickness Of Grey Matter Predicts Ability To Recognize Faces And Objects

When you see a familiar face, when a bird-watcher catches a glimpse of a rare bird perched on a limb, or when a car-fancier spots a classic auto driving past, the same small region in the brain becomes engaged. For almost two decades, neuroscientists have known that this area, called…Continue readingThickness Of Grey Matter Predicts Ability To Recognize Faces And Objects

Cerebral Cortex Shape Correlated With Genetic Ancestry

The three-dimensional shape of the cerebral cortex, the wrinkled outer layer of the brain controlling many functions of thinking and sensation, strongly correlates with ancestral background, researchers at the University of California, San Diego have found. The study could lead to more precise studies of brain anatomy going forward, and…Continue readingCerebral Cortex Shape Correlated With Genetic Ancestry
