Study unveils surprising mechanism that controls brain formation

A study from The Scripps Research Institute has unveiled a surprising mechanism that controls brain formation. The findings have implications for understanding a host of diseases, including some forms of mental retardation, epilepsy, schizophrenia, and autism.

Coordinated behavior occurs whether or not neurons are actually connected via synapses

The brain-awake and sleeping-is awash in electrical activity, and not just from the individual pings of single neurons communicating with each other. In fact, the brain is enveloped in countless overlapping electric fields, generated by the neural circuits of scores of communicating neurons.

Sleep on it to remember it better: Study

A new study says that the best way to remember something important is to remember it while you are asleep. The research, led by Bjorn Rasch of the University of Basel in Switzerland says that newly learned memories during sleep rather than when awake does a better job of strengthening the memory trace. This could help people with disorders such as post-traumatic stress disorder (PTSD) feel researchers.

Population of highly active neurons could provide insight into neocortex

Carnegie Mellon University researchers have found that within the brain's neocortex lies a subnetwork of highly active neurons that behave much like people in social networks.

AHNPs may serve as effective treatment for epilepsy and other disorders with altered neuronal circuitry

Epilepsy research is reaching beyond improving the means for quelling symptoms to the exploration of potential modalities for correcting or reversing alterations in neural function that underlay some forms of the disorder.

Study finds structural similarities in neocortices of humans and chickens

For more than a century, neuroscientists believed that the brains of humans and other mammals differed from the brains of other animals, such as birds (and so were presumably better). This belief was based, in part, upon the readily evident physical structure of the neocortex, the region of the brain responsible for complex cognitive behaviors.

UCSF scientists discover new stem cell in developing human brain

UCSF scientists have discovered a new stem cell in the developing human brain. The cell produces nerve cells that help form the neocortex - the site of higher cognitive function -- and likely accounts for the dramatic expansion of the region in the lineages that lead to man, the researchers say.

UCSF approach may one day be used to create new periods of plasticity in human brain

UCSF scientists report that they were able to prompt a new period of "plasticity," or capacity for change, in the neural circuitry of the visual cortex of juvenile mice. The approach, they say, might some day be used to create new periods of plasticity in the human brain that would allow for the repair of neural circuits following injury or disease.

Study: Cell-based strategy for treating neurodegenerative diseases

UCSF scientists have used a novel cell-based strategy to treat motor symptoms in rats with a disease designed to mimic Parkinson's disease.

Findings may shed light on the origins of autism and attention deficit disorders

Like a spotlight that illuminates an otherwise dark scene, attention brings to mind specific details of our environment while shutting others out. A new study by researchers at the Salk Institute for Biological Studies shows that the superior colliculus, a brain structure that primarily had been known for its role in the control of eye and head movements, is crucial for moving the mind's spotlight.

Scientists identify the first genetic mechanism that generates the cerebral cortex

The cerebral cortex, the largest and most complex component of the brain, is unique to mammals and alone has evolved human specializations. Although at first all stem cells in charge of building the cerebral cortex-the outermost layer of neurons commonly referred to as gray matter-are created equal, soon they irrevocably commit to forming specific cortical regions. But how the stem cells' destiny is determined has remained an open question.

Mechanism during sleep responsible for memory formation identified

A Rutgers University, Newark and Coll-ge de France, Paris research team has pinpointed for the first time the mechanism that takes place during sleep that causes learning and memory formation to occur.

New study shows striking similarity in the evolution of cities and human brains

Cities are organized like brains, and the evolution of cities mirrors the evolution of human and animal brains, according to a new study by researchers at Rensselaer Polytechnic Institute.

Stages of sleep have distinct influence on process of learning and memory

Research on the sleeping brain has revealed some fascinating stage-dependent interactions between areas involved in formation and storage of long term memories.

Researchers find evidence for precise communication across brain areas during sleep

By listening in on the chatter between neurons in various parts of the brain, researchers from the California Institute of Technology (Caltech) have taken steps toward fully understanding just how memories are formed, transferred, and ultimately stored in the brain--and how that process varies throughout the various stages of sleep.

Gene find sheds light on motor neuron diseases like amyotrophic lateral sclerosis

Scientists have identified a gene in mice that plays a central role in the proper development of one of the nerve cells that goes bad in amyotrophic lateral sclerosis, or Lou Gehrig's disease, and some other diseases that affect our motor neurons.

Cigarette smoking may accelerate disability in multiple sclerosis

Persons with multiple sclerosis who smoke risk increasing the amount of brain tissue shrinkage, a consequence of MS, and the subsequent severity of their disease, new research conducted at the Buffalo Neuroimaging Analysis Center (BNAC) at the University at Buffalo has shown.

Memory storage molecule PKMzeta stores memories in neocortex

The memory storage molecule PKMzeta maintains long-term memories in the neocortex and its presence is continually required in order for the memory to endure, according to a finding by researchers at the Weizmann Institute in Rehovot, Israel and SUNY Downstate Medical Center in Brooklyn, New York.

Sexual selection had an important influence on primates brains

When male primates tussle and females develop their social skills it leaves a permanent mark, on their brains.

Scientists answer brain mystery

The taste of champagne, the sound of a train, the flash of a pop fly into left field - indeed all of human perception ' begins in the brain's center. That's where sensory information passes from the thalamus to the neocortex for processing.
