Brain tissue

Source: Tufts University Summary: A team of researchers has developed 3-D human tissue culture models for the central nervous system that mimic the structural and functional features of the brain. The new 3-D brain tissue models overcome a key challenge of previous models -the availability of human source neurons. This is dueRead More →

Neurons

Source: Medical College of Georgia at Augusta University Summary: Brain regions best known for recognizing the potential horror of a hurricane also help us recognize, appreciate and categorize our food, scientists report.   More Information: Jun Liu et al, “Neural Coding of Appetitive Food Experiences in the Amygdala”, Neurobiology of Learning and Memory (2018). DOI:Read More →

mental disorder

Source: University of New South Wales Summary: Researchers have identified immune cells in greater amounts in the brains of some people with schizophrenia. This new research could open doors to new treatments, research and therapies. One in every 100 Australians lives with schizophrenia. No single cause of schizophrenia has been identified, and this hasRead More →

ability to see in low-light conditions

Source: Duke University Summary: Retinal circuits that were thought to be unchanging and programmed for specific tasks are adaptable to different light conditions, said the scientists who identified how the retina reprograms itself for low light. More Information: Xiaoyang Yao et al, “Gap Junctions Contribute to Differential Light Adaptation Across Selective Retinal GanglionRead More →

ALS motor neurons

Source: Northwestern University Summary: Researchers have discovered that some neurons affected by amyotrophic lateral sclerosis (ALS) display hypo-excitability, using a new method to measure electrical activity in cells. The excitability changes observed in ALS patient neurons most likely represent the early steps in the disease process. The fact that theseRead More →

Post-traumatic stress disorder

Source: Ecole Polytechnique Federale de Lausanne Summary: For the first time, a new study finding shed light on the processes that underlie the successful treatment of traumatic memories. Memories of traumatic experiences can lead to mental health issues such as post-traumatic stress disorder (PTSD), which can destroy a person’s life. It is currently estimatedRead More →
