UMD News

Research has already shown that up to half of all children diagnosed with ADHD have parents with untreated ADHD as well. UMD psychologists now want to determine whether treating parents with the disorder will improve their parenting and help their children with a shared diagnosis.
People with dementia in the U.S. are notoriously left out of the conversation about their own healthcare decisions. Now, one UMD information scientist is exploring how technology can enable those with dementia to remain involved in decision making and to age in their own homes.

All of us make many decisions every day. For most things, there’s usually no right answer, so we decide using values rooted in our past experiences. Now, neuroscientists have identified the part of the mammalian brain that stores information essential to such value-based decision making. Researchers zeroed in on a particular brain region known as the retrosplenial cortex and captured in real time what goes on in the brains of mice as they make decisions. While such neural activity isn’t usually visible, in this case researchers genetically engineered mice so that their neurons, when activated, expressed a protein that glowed.
Frontotemporal dementia is the most common type of early onset dementia, typically beginning between ages 40 and 65 and affecting the frontal and temporal lobes of the brain. A subgroup of patients with frontotemporal dementia have a specific genetic mutation that prevents brain cells from making a protein called progranulin. Although progranulin is not widely understood, its absence is linked to the disease. Now, a group of researchers have discovered that, after aminoglycoside antibiotics were added to neuronal cells with this mutation, the cells started making the full-length progranulin protein by skipping the mutation.
Neurologists had long assumed that brain diseases impacting language abilities would manifest in essentially the same way in patients around the world. However, recent discoveries have begun to question that assumption. New research shows that English and Italian speakers with dementia-related language impairment experience distinct kinds of speech and reading difficulties based on features of their native languages. For instance, Italian speakers with dyslexia tend to have less severe reading impairment than English or French speakers due to Italian’s simpler and more phonetic spelling.
Computers are being trained to “see” the patterns of disease hidden in our cells and tissues, and now comes word of yet another remarkable use of computer-generated artificial intelligence: swiftly providing neurosurgeons with valuable, real-time information about what type of brain tumor is present, while the patient is still on the operating table. Sending out a biopsy to an expert pathologist and getting back a diagnosis traditionally takes about 40 minutes, but the researchers found they could take a small tumor biopsy during surgery, feed it into a trained computer in the operating room, and receive a diagnosis that rivals the accuracy of an expert pathologist.
About four years ago, pathologist Matthew Anderson was examining slices of postmortem brain tissue from an individual with autism under a microscope when he noticed something extremely odd: T cells swarming around a narrow space between blood vessels and neural tissue. The cells were somehow getting through the blood-brain barrier. He soon identified more T-cell swarms in a few other postmortem brains of people who had been diagnosed with autism. Anderson tested whether the neurological features he was observing were specific to autism by examining postmortem brain samples from 25 people with ASD and 30 developmentally normal controls.
When a human or animal is about to perform an action, its dopamine neurons make a prediction about the expected reward. Once the actual reward is received, the neurons fire off an amount of dopamine that corresponds to the prediction error. The dopamine, in other words, serves as a correction signal, telling the neurons to adjust their predictions until they converge to reality. Now, researchers have uncovered new details about how dopamine helps the brain learn by optimizing reinforcement-learning algorithms—specifically, by introducing an improved reinforcement-learning algorithm that changes the way it predicts rewards.
While the brain itself has no direct way for disposing of cellular waste, tiny vessels lining the interior of the skull collect tissue waste and dispose of it through the body’s lymphatic system. It is this disposal system that researchers exploited to offer an immunotherapeutic treatment for glioblastoma patients. The researchers introduced the gene known as vascular endothelial growth factor C, or VEGF-C, into the cerebrospinal fluid of mice with glioblastoma and observed an increased level of T cell response to tumors in the brain. When combined with immunotherapy, the VEGF-C treatment significantly extended survival.
When you expect a bad experience and then it doesn’t happen, you have a distinctly positive feeling. A new study of fear extinction training in mice may suggest why: the brain cells that are key for learning not to feel afraid anymore are the same ones that help encode feelings of reward. Specifically, the study shows that fear extinction memories and feelings of reward alike are stored by neurons that express the gene Ppp1r1b in the posterior of the basolateral amygdala, a region known to assign associations of aversive or rewarding feelings, or “valence,” with memories.
Researchers have shown therapeutic efficacy of a new experimental drug in mouse models of Alzheimer’s disease and a rare genetic form of epilepsy known as Dravet syndrome. The small molecule increases the activity of a subset of neurotransmitter (NMDA) receptors that are found at synapses. These receptors are known to support cognition and memory by enhancing communication between neurons. The new research shows that enhancing the activity of synaptic NMDA receptors helps restore the brain’s rhythms to normal patterns and improves memory.
Researchers report that in an alcohol-dependent mouse model, the rodent brain’s functional architecture is substantially remodeled, but when deprived of alcohol, the mice displayed increased coordinated brain activity and reduced modularity. The findings also identified several previously unsuspected regions of the brain relevant to alcohol consumption.
Xenobots are tiny living robots that have been created using cells taken from frog embryos. Each is less than a millimeter across, but one can propel itself through water using two stumpy limbs, while another has a kind of pouch that it could use to carry a small load. Such robots could one day be used to clean up microplastics, digest toxic materials, or even deliver drugs inside human bodies.
This first-person account of UH's Brain and Behavior Lab describes the experience of encountering some commonly-used tools in cognitive neuroscience from a lay perspective. In particular, the writer mentions a new technology called Optically Pumped Magnetometry (OPM), a new type of MEG device. UH is the first university laboratory in the U.S. with access to OPM.
