  • Remembering Novelty

    The brain and its functions still pose many open questions. One of them is how exactly we form long-term memories about the environment. In a new study Ryuichi Shigemoto and his group from the Institute of Science and Technology Austria (IST Austria) together with researchers from Aarhus University and the National Institute for Physiological Sciences […]

  • New study reveals how the nervous system mutes or boosts sensory information to make behavioral decisions

    Fruit flies may be able to teach researchers a thing or two about artificial intelligence. University of Michigan biologists and their colleagues have uncovered a neural network that enables Drosophila melanogaster fruit flies to convert external stimuli of varying intensities into a “yes or no” decision about when to act. The research, scheduled to publish […]

  • Automatic decision-making prevents us harming others – new study

    A team based in the Universities of Birmingham and Oxford in the UK and Yale University in the US investigated the different approaches to avoiding pain for the first time. They found that when learning to avoid harming ourselves, our decision-making tends to be more forward-looking and deliberative. The findings, published in Proceedings of the […]

  • UofSC research finds trigger that leads to faster nerve healing

    A new study published in Current Biology identifies the biological triggers that promote quicker nerve regeneration. From their previous studies, the researchers knew that damaged nerves regrow more quickly when “stress granules” in the site of the nerve injury are broken apart. Now they know what causes those stress granules to disassemble through a process […]

  • Astrocytes build synapses after cocaine use in mice

    Drugs of abuse, like cocaine, are so addictive due in part to their cellular interaction, creating strong cellular memories in the brain that promote compulsive behaviors. Researchers have tried to understand the formation of these memories in hopes of finding ways to disrupt them as a potential treatment for substance use disorder (SUD). A new […]

  • Study Reveals Most Effective Drugs for Common Type of Neuropathic Pain

    More than 20 million people in the U.S. suffer neuropathic pain. At least 25% of those cases are classified as unexplained and considered cryptogenic sensory polyneuropathy (CSPN). There is no information to guide a physician’s drug choices to treat CSPN, but a researcher from the University of Missouri School of Medicine and MU Health Care […]

  • Reelin-Nrp1 Interaction Regulates Neocortical Dendrite Development

    The mammalian neocortex has an orderly and beautiful six-layer structure. Neurons in each layer develop the dendrites and form a normal network. Recently, it has been reported that dendritic abnormalities are found in patients with psychiatric disorders such as schizophrenia and autism. Therefore, understanding the mechanism by which dendrites are normally formed is important for […]

  • New Study May Reveal Link to Lipids Playing a Key Role in Parkinson’s Disease

    In a novel research study conducted by a team from the Neuroregeneration Institute at McLean Hospital, investigators believe they have found key brain cell type changes involving lipids, inflammation, and the development of Parkinson’s disease (PD). Their findings appear in the current issue of the Proceedings of the National Academy of Sciences of the United […]

  • Study explains the process that exacerbates MS

    People with multiple sclerosis (MS) gradually develop increasing functional impairment. Researchers at Karolinska Institutet have now found a possible explanation for the progressive course of the disease in mice and how it can be reversed. The study, which is published in Science Immunology, can prove valuable to future treatments.

  • 抑制神经元信号的新方法

    位于神经元细胞膜上的离子通道可限制带电离子进出神经元,当有足够多的特定离子涌入神经元后就会促成放电现象的产生,而癫痫患者大脑内的神经细胞正是因为过于容易放电而导致了一系列病理特征的产生。因此,抗癫痫类药物大多会以这类离子通道为治疗靶点,通过与细胞膜上的相关位点进行结合从而对特定离子通道的大门进行封锁,以此来抑制神经元的放电行为。而瑞典林雪平大学的研究团队则于最近找到了一个可用作为新靶点的结合位点。不同于以往那些被液体所环绕的结合部位,该结合位点位于双层磷脂膜结构的内部,是一种极其罕见的脂质结合口袋。鉴于现有的抗癫痫类药物并不十分有效且都具有一定的副作用,研究人员将希望寄托在了这一新发现的药物靶点上,希望有科学家能找到可与之进行结合的化学物质。
