Neuronal selectivity, a neuron’s ability to respond to specific stimuli, is critical to determine how the neuron behaves to different cues. A team of researchers at Johns Hopkins University, including Kavli NDI members, Ingie Hong, Richard Huganir, Seth Blackshaw, Dwight E. Bergles and Solange P. Brown have identified a subtype of receptors, Calcium Permeable AMPA receptors, that are responsible for controlling neuronal selectivity.
Kavli NDI PI, Dwight Bergles and team leverage the power of AI to make fundamental discoveries in neuroscience.
Neural circuits undergo changes when learning a new sound. Kavli NDI PI, Patrick Kanold and team, using a combination of advanced imaging techniques and AI, identified precise brain regions that are that recruited during this learning process.

Kavli NDI Postdoctoral Fellow, Dr. Jonathan Ling, and colleagues developed a computational data mining resource, ASCOT, to determine how novel cell type-specific splicing variants are regulated across the nervous system.
The Knierim Lab of MBI and the LIMBS Lab of the Department of Mechanical Engineering (N. Cowan, PI) published a study in the journal Nature that showed how the brain translates movement information (e.g., speed and direction) into a position signal on the brain’s “cognitive map.”
During gambling, bias is often generated by internal factors, including individual preferences, past experience, or emotions, and can move a person toward or away from risky behavior. The neural mechanisms responsible for generating internal bias are largely unknown, limiting the treatment of patients with neurological diseases that impair decision-making. Members of the Johns Hopkins University laboratory of Associate Professor of Biomedical Engineering, Dr. Sridevi Sarma, published a paper in Proceedings of the National Academy of Sciences that identifies a 'push-pull' dynamic between the brain's hemispheres during high-risk betting.
Magnetic resonance imaging (MRI) has substantially enhanced our ability to examine the brain anatomy and functions in neurodegenerative diseases. In Huntington's disease (HD), regional brain atrophy begins many years prior to the motor onset (during the "premanifest" period), but the spatiotemporal pattern of regional atrophy across the brain has not been fully characterized.
Oligodendrocyte generation in the adult CNS provides a means to adapt the properties of circuits to changes in life experience. Recent research by Hopkins Department of Neuroscience and Kavli NDI researchers Hughes EG, Orthmann-Murphy JL et al., demonstrates how oligodendrocytes are effected by sensory experience to modify mature cortical circuits.
Multiple populations of wake-promoting neurons have been characterized in mammals, but few sleep-promoting neurons have been identified. Johns Hopkins Kavli NDI researchers Seth Blackshaw and colleagues have identified specific neurons that regulate sleep by inhibiting the activity of wake-promoting cells.
A Johns Hopkins University mathematician and computer scientist joined an international team of neuroscientists to create a complete map, known as a "connectome", of the learning and memory center of the fruit fly larva brain, an early step toward mapping how all animal brains work.
A recent report by, resulting from collaborative efforts by Kavli NDI affiliated laboratories of Drs. Solange Brown and Loyal Goff, reveals that axonal projection pattern, laminar position, and activity state define significant axes of variation that contribute both to the transcriptional identity of individual neurons and to the transcriptional heterogeneity within each neuronal subtype.
Congratulations to Adam Charles on receiving the NSF Career Award.
While it was previously understood that the brain uses landmarks for location and speed calibration. However, it wasn't clear if these landmarks were essential for recalibrating speed. Kavli NDI PI James Kneirim and Noah Cowan demonstrates that visual motion cues alone can recalibrate, even when visual landmarks are absent.
We are pleased to announce the Kavli NDI Distinguished Doctoral and Postdoctoral Fellowship Awardees for the 2024-25 cycle.

By studying the genome of a kind of octopus not known for its friendliness toward its peers, then testing its behavioral reaction to a popular mood-altering drug called MDMA or “ecstasy,” scientists say they have found preliminary evidence of an evolutionary link between the social behaviors of the sea creature and humans, species separated by 500 million years on the evolutionary tree.
Dr. Richard Huganir, a Johns Hopkins Department of Neuroscience faculty member since 1988, is the latest researcher to join the ranks of the Bloomberg Distinguished Professors, a group of interdisciplinary scholars at Hopkins who are working to address major world problems and teach the next generation.
The trend toward a quantitative, task based, understanding of medical images leads to the simple goal of answering “how many bits of information would one expect a medical image to contain about disease status?” Knowing the answer to this question could impact a clinician's decision of whether or not to order an imaging study, particularly in the case where it involves ionizing radiation. This quantity can be studied in terms of mutual information between disease status and anatomical form, and is the problem being tackled by Johns Hopkins Kavli NDI researchers, Daniel Tward and Michael Miller.
Kavli NDI associate Jeremy Nathans, with colleagues Chris Cho and Phillip Smallwood, address a series of open questions related to the regulation of mammalian CNS angiogenesis and blood-brain barrier maintenance. In their recent report in Neuron, they identify two proteins, Gpr124 and Reck, as essential cofactors for Wnt signaling that mediates vascularization of the mammalian brain and spinal cord.
For the first time, scientists have watched sleep transform the brain. The research confirms a longstanding theory about the value of sleep—and helps explain why sleep deprivation messes with our ability to remember.
