- Feb. 21, 2018 : MIT Technology Review: A Less-Artificial Intelligence
A fair number of engineers working on artificial intelligence don’t care whether their systems resemble real brains or not, as long as they perform well. But even today’s best systems can generalize only if fed thousands of samples, and they can’t transfer their generalizations to new contexts. This leaves AI vulnerable to attackers, who can trick it with tiny tweaks to the data. Neuroscientist Andreas Tolias believes that brain-like features could fix these problems.

- Sept. 27, 2017: Dr. Matthew Rasband receives the United States - Israel Binational Science Foundation Neufeld Memorial Research Award
Dr. Rasband's United States - Israel Binational Science Foundation-funded research involves a complex study of nodes of Ranvier, also known as myelin-sheath gaps. Myelin is an insulating membrane sheath produced by specialized glial cells in the central nervous system (which includes nerves in the brain and spinal cord) and the peripheral nervous system (nerves throughout the rest of the body.) Myelin enables fast and efficient nerve conduction that is essential for proper body function, and in some cases, even survival. Destruction of myelin leads to several neurological diseases, such as multiple sclerosis, and is also associated with psychiatric and neurodegenerative disorders.
- Sept. 11, 2017: DNA looping may lead to opportunities to treat brain tumors
A recent paper from Dr. Deneen's lab in the journal Nature Neuroscience describes the mechanism by which normal brain cells regulate the expression of the NFIA gene, which is important for both normal brain development and brain tumor growth.
- March 20, 2017: Neurons deep in brain more active than once thought
It's the part of the brain that makes sure you cannot tickle yourself. The cerebellum, an apple-sized region near the base of the skull, senses that your own fingers are the ones trying to tickle, and cancels your usual response. Cerebellar neurons, which were thought to fire only rarely as they take in information from the senses, are in fact far more active than previously suspected, according to a recent study in the journal Nature Neuroscience. “The study is the first to look at the activity of these neurons, known as granule cells, in the brains of living animals while they are learning a task,” said Dr. Javier Medina, associate professor and the Vivian L. Smith Endowed Chair in Neuroscience at Baylor College of Medicine, and a senior co-author with Dr. Sam Wang, professor of molecular biology and the Princeton Neuroscience Institute. "We knew very little about how these neurons in the cerebellum were firing when the brain is engaged in behavior.”
- Feb. 7, 2017: Vital links between brain tumors, epileptic seizures found
Detecting brain tumors at the earliest possible stage and eliminating them before seizures begin might be possible one day, according to research by scientists at Baylor College of Medicine and Texas Children’s Hospital, including Neuroscience Associate Professor Dr. Benjamin Deneen. In the study, which is published in the journal Nature Neuroscience, the scientists report that the emergence of specific brain cells during brain tumor progression in a mouse model marked the onset of seizures and brain tumor invasion. An improved understanding of how brain tumors cause seizures can potentially lead to strategies to prevent them or treat them.

- Oct. 9, 2015: Dr. Mingshan Xue wins Janett Rosenberg Trubatch Career Development Award from Society for Neuroscience
Supported by the Trubatch family, the Career Development Award recognizes two recipients each year for originality and creativity in neuroscience research conducted by early-career professionals. Mingshan Xue, PhD, an assistant professor of neuroscience at Baylor College of Medicine, has made important contributions to the study of cortical circuits. As a graduate student at Baylor College of Medicine, Xue demonstrated that a protein that regulates neurotransmitter release performs opposite functions in mammals and the Drosophila fly model, highlighting the importance of species differences. Xue’s research also elucidated how this and other proteins are able to control neurotransmitter release. His current research focuses on the balance of excitatory and inhibitory signaling in the cortex, and how this balance is disrupted in neurological disorders like autism spectrum disorder and epilepsy.
