Deep inside the brain: Unraveling the dense networks in the cerebral cortex

October 24, 2019 0 Comments Animal Learning and Intelligence, Biology, Brain Tumor, Brain-Computer Interfaces, Intelligence, mice, Nervous System, neuroscience, Psychology Research

Mammalian brains, with their unmatched number of nerve cells and density of communication, are the most complex networks known. While methods to analyze neuronal networks sparsely have been available for decades, the dense mapping of neuronal circuits is a major scientific challenge. Researchers have now succeeded in the dense connectomic mapping of brain tissue from the cerebral cortex, and quantify the possible imprint of learning in the circuit.

Q-suite motor assessment tool promising for evaluating Huntington's disease

October 22, 2019 0 Comments Amyotrophic Lateral Sclerosis, Child Psychology, Children's Health, Huntington's Disease, Nervous System, neuroscience, Psychology Research, Stress

In clinical trials of adults with Huntington's disease (HD) the Q-Suite Motor Assessment Tool (Q-Motor) has proven to be helpful to detect and quantitate subtle motor abnormalities. With the anticipated arrival of preventive gene therapies that will most likely be administered to young children known to be carriers of the HD mutation, it is crucial to have a means to evaluate motor abilities in children that is sensitive to the child's stage of development.

Scientists have discovered a new lineage of specialized brain cells, called Hoxb8-lineage microglia, and established a link between the lineage and OCD and anxiety in mice. Their experiments proved that Hoxb8-lineage microglia prevent mice from displaying OCD behaviors. Additionally, they found that female sex hormones caused more severe OCD behaviors and induced added anxiety in the mice.

Unique brain changes in people with Huntington's disease

October 21, 2019 0 Comments Birth Defects, Brain-Computer Interfaces, Disorders and Syndromes, Healthy Aging, Huntington's Disease, Nervous System, neuroscience, Psychology Research

The part of the brain that selectively degenerates in people with Huntington's disease (HD), called the striatum, is almost entirely destroyed in the late stages of the disease. Brain samples from mutant HD gene positive individuals who had not yet developed symptoms by time of death are extremely rare. As a consequence, very little is known about the active disease process that causes the devastating symptoms of HD.

A new discovery: How our memories stabilize while we sleep

Scientists have shown that delta waves emitted while we sleep are not generalized periods of silence during which the cortex rests, as has been described for decades in the scientific literature. Instead, they isolate assemblies of neurons that play an essential role in long-term memory formation.

A brain mapping technique called BARseq is capable of mapping thousands of neurons in a single mouse, at single neuron resolution, while also detailing which neuron expresses what genes. It could be a game-changer for how neuroscientists look at brains.
