After the Ice Bucket: Thawing Amyotrophic Lateral Sclerosis with Predictive Medicine
(2017-10-16)The prolific 2014 ALS Association’s Ice Bucket Challenge commenced the world-wide dumping of ice water on the heads of courageous supporters to bring awareness and research funding to a lesser-known yet fatal neurodegenerative ... -
Analysis of social behavior in Lake Malawi cichlids using automated behavior phenotying
(2021-09-20)In the wild, behaviors are often expressed over long time periods in complex and dynamic environments, and many behaviors include direct interaction with the environment itself. However, measuring behavior in naturalistic ... -
Ancestral Remembrances and Descendant Recollections – Multi-generational Studies of Structure and Function in the Nervous System
(2018-03-26)Historical events have generated data indicating that stressors experienced by populations, affect not only the individuals directly exposed to them, but also descendants. Using animal models, our research (and my talk) ... -
Arbitration between Actions and Habits: Cortical Regulators and the Influence of Cocaine
(2018-01-29)Selecting actions based on their consequences is essential to day-to-day function and yet, is impaired in neuropsychiatric diseases like addiction. Goal-directed action selection likely requires the coordinated output of ... -
Artificial Intelligence platforms for translatable closed-loop neuromodulation
(2021-09-27)Closed-loop neuromodulation and direct neural interface systems provide powerful tools for elucidating the causal effects of regulating neurophysiological processes and restoring function, and promise to enable precision ... -
Biological and Bionic Hands: Natural Neural Coding and Artificial Perception
(2018-01-22)Our ability to manipulate objects dexterously relies fundamentally on sensory signals originating from the hand. To restore motor function with upper-limb neuroprostheses requires that somatosensory feedback be provided ... -
Biophysically Principled Modeling of Human MEG/EEG Signals Reveals Novel Mechanisms and Meaning of Brain Rhythms
(2016-11-28)Magneto- and Electro-encephalography (MEG/EEG) are among the most powerful technologies to non-invasively record large-scale activity from humans with fine temporal and spatial resolution. These signals provide reliable ... -
Brain dynamics related to short-term memory and learning
(2021-02-15)Through the combination of in vivo optical imaging and chronic expression of genetically encoded calcium indicators it is now feasible to directly 'watch' brain activity patterns related to specific behaviors. I will ... -
Bringing Bioelectricity to Light
(2017-02-06)To study a neural circuit, one would like to probe the activity of many neurons, with high resolution in space and time. A key challenge has been the difficulty of visualizing changes in transmembrane potential. We discovered ... -
Built to Learn: Insights into Nature and Nurture from Blindness and Cognitive Expertise
(2022-12-05)Humans are unique among animals not only in their shared cognitive capacities but also in their remarkable adaptability to diverse environments. Studies with people born blind provide insights into the mechanisms of human ... -
Cholinergic Sensorimotor Integration Regulates Rapid Behavioral Decisions
(2018-04-16)During active exploration, the spatial and temporal pattern of the sensory cue perceived by an animal is shaped by the animal’s own movement. Thus, to move towards a sensory target, the nervous system needs to make rapid ... -
Clarifying the Brain Networks that Support Word Learning and Processing
(2021-10-25)Across development, children continually encounter new words and incorporate these words into their vocabulary. This ability to learn new words in turn influences how children process spoken language, which subsequently ... -
Cortical Circuits of Vision
(2017-04-24)The diversity of neuron types and synaptic connectivity patterns in the mammalian cerebral cortex is astonishing. How this cellular and synaptic diversity contributes to cortical function is just beginning to emerge. Using ... -
Corticocortical Communication
(2020-02-10)Most brain functions involve neuronal population activity that is distributed across multiple areas. The routing of signals through this distributed network is flexible, changing from moment-to-moment to meet task demands. ... -
Decoding Distinct Attention and Working Memory States from Human EEG
(2021-10-18)Working memory allows us to temporarily hold task relevant information from the environment “in mind” so that we can manipulate or act upon it. As such, it is a critical workspace for many cognitive operations and individual ... -
Deconstructing Memory Circuits at Cell Type-specific Resolution
(2019-01-28)Nelson Spruston studies the hippocampus, with an emphasis on uncovering the diversity and complexity of cells and synapses that allow this brain structure to contribute to memory-guided behavior, such as spatial navigation ... -
Defining neuromodulation targets for PTSD using neuroimaging
(2021-02-01)Posttraumatic stress disorder (PTSD) is a serious psychiatric condition that affects 6-8% of the general population and 30-46% of military or highly traumatized urban populations. Different neuromodulation techniques are ... -
Developmental Cognitive Neuroscience in an Age of Discovery
(2022-01-31)Just as the brain changes over the life course to meet unique challenges and make new discoveries at each developmental phase, so too is the field of cognitive neuroscience changing. Over the years, we have seen significant ... -
Dissecting hand dexterity and recovery processes for effective rehabilitation
(2021-04-12)Hand dexterity is the hallmark of human skill and intelligence. From Pablo Casals’ sublime cello playing to the mundane task of tying one’s shoelace, the level of dexterity in humans stands out among our primate relatives. ... -
