Next-GenerationMultiphoton Imaging for Optogenetics

At the 2018 Annual Meeting of the Society for Neuroscience, Bruker announced the release of the Ultima 2Pplus next-generation multiphoton, all-optical stimulation and simultaneous imaging platform for neurobiology applications.

			Hyperactive immune system implicated in aging brain disorders In a study of fruit flies, NIH scientists suggested that the body's immune system may play a critical role in the damage caused by aging brain disorders. The results are based on experiments in which the researchers altered the activity of Cdk5, a gene that preclinical studies have suggested is important for early brain development and may be involved in neurodegenerative diseases, such as ALS, Alzheimer's and Parkinson's disease.

			New mechanism may explain neurons shrinking in Huntington's disease A hallmark of neurodegenerative diseases like Huntington's is the progressive death of nerve cells in the brain. The cells don't die quickly, though. They first start to disconnect from each other because their neurites -- long finger-like extensions that make connections all through the brain -- become smaller.

	Antibodies and Huntington's: Diagnosis & Treatment Huntington’s disease is a genetically inherited neurodegenerative disorder caused by an autosomal dominant mutation in the huntingtin gene resulting in a trinucleotide (CAG) repeat expansion with over 40 repeats.

	MPFI researchers identify synaptic logic for connections between two brain hemispheres Researchers at the Max Planck Florida Institute for Neuroscience have developed a new combination of technologies that allows them to identify the functional properties of individual synapses that link the two hemispheres and determine how they are arranged within a neuron's dendritic field.

	Faulty brain immune cells cause Alzheimer's disease Mutations of the TREM2 gene can significantly increase the risk of Alzheimer's disease. Scientists from the German Center for Neurodegenerative Diseases and the Ludwig-Maximilians-University Munich now shed light on the reasons why TREM2 is so important for brain health.

	Pitt study delves deeper into how electrical stimulation activates neurons Electrical stimulation of the brain is common practice in neuroscience research and is an increasingly common and effective clinical therapy for a variety of neurological disorders. However, there is limited understanding of why this treatment works at the neural level.

	Researchers reveal five insomnia types Researchers at the Netherlands Institute for Neuroscience revealed that there are five types of insomnia. This finding was published on Monday January 7 by The Lancet Psychiatry. A commentary in the journal stated that the finding could be a new page in the history of insomnia, promoting discoveries on mechanisms and interventions.

	Simple blood test reliably detects signs of Alzheimer’s damage before symptoms A simple blood test reliably detects signs of brain damage in people on the path to developing Alzheimer's disease - even before they show signs of confusion and memory loss, according to a new study from Washington University School of Medicine in St. Louis and the German Center for Neurodegenerative Diseases in Germany.

	Study evaluates first-ever Robotic Visualization System for neurosurgery A one-year study was recently conducted to perform a comprehensive assessment of the new, cutting-edge ZEISS KINEVO 900, a first-ever Robotic Visualization System® and compares its performance to the previous model of ZEISS surgical microscope.
