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. ... -
Dissection of Neural Circuit Function and Degeneration from a Subcellular Perspective
(2020-02-17)How do neurons perform the set of signaling functions necessary for proper circuit function? We aim to uncover cellular and molecular mechanisms that shape excitability among different mammalian neurons. We approach these ... -
Distinct Neuronal Ensembles Encode Sensory Stimulus Context in the Neocortex
(2018-11-19)The Hamm lab conducts basic research on cortical microcircuitry with paradigms and approaches designed to provide deeper insight into neuropsychiatric disease. Sensory processing abnormalities in schizophrenia (SZ) undermine ... -
The Dynamics of Perceptual Decision Making
(2017-02-13)How do humans and other animals make decisions? A large body of work has investigated this question in the perceptual domain where subjects make decisions about simple visual stimuli. A critical question concerns the ... -
Ecological resources and the evolution of parent-offspring interactions
(2020-11-23)Animal behavior is a key component of biological adaptations, where fitness relies on the ability to find mates, acquire food, and avoid predation. Variation in the availability of key ecological resources can drive the ... -
Effects of Nicotine on Brain and Behavior: How nAChRs Modulate Circuits Related to Mood and Aggression
(2018-03-12)Acetylcholine signaling influences behaviors related to diverse functions, including drug abuse, attention, food intake, and mood. The ability of acetylcholine to coordinate the response of neuronal networks in many brain ... -
Emergent Computation and Learning from Assemblies of Neurons
(2022-09-19)Despite breathtaking advances in ML, and in our understanding of the brain at the level of neurons, synapses, and neural circuits, we lack a satisfactory explanation for the brain's performance in perception, cognition, ... -
Engineering Neurotechnology for the Surgical Treatment of Epilepsy: A Surgeon-scientist-non-engineer’s Perspective
(2018-10-29)(1) Cellular and Gene Therapy for Parkinson’s Disease Elucidation of the role of axon guidance molecules in the development and reconstruction of the nigrostriatal pathway, which degenerates in Parkinson’s Disease, and ... -
Epilepsy – Beyond the Local Network
(2019-10-28)While human research has emphasized the large-scale network disruptions in the epilepsies and their co-morbidities, basic science has typically focused on local networks. In rodents, more general large-scale network dynamics ... -
Evolution and Development of a Minimal Nervous System in our Closest Invertebrate Relatives
(2019-11-25)Animal behavior depends both on the intrinsic properties of individual neurons and how these neurons connect to and modulate one another. A major focus of modern neuroscience is to dissect behavior at the level of individual ... -
Evolutionarily Conserved Mechanisms of Sociality
(2019-10-07)There is an extraordinary amount of variation in social behavior within and across species. However, when phenotypic convergence in behavior (e.g., sociality) is observed, it begs the question as to whether the same neural ... -
Feasibility and acceptability of using affordable robots for persons with motor and/or cognitive impairments in low-resource settings
(2022-04-18)Robots in Medicine are here to stay. While their use in medicine and rehabilitation is increasing in high income countries, there is still a need to find ways to extend their utility to more diverse rehabilitation populations ... -
Finding Low-dimensional Structure in Large-scale Neural Recordings
(2018-02-12)Improvements in neural recording technologies have rapidly increased the number of neurons that it is now possible to record from. Along with these improvements, analyses of neural information processing are moving from ... -
Flexible Learning and Decision Making in a Changing World
(2020-10-19)Survival requires proper association of reward outcomes to choices and actions that precede them. To learn successfully, however, the brain must constantly adjust how it incorporates each reward feedback because the ... -
From Spikes to Factors: Understanding Large-scale Neural Computations
(2022-04-04)It is widely accepted that human cognition is the product of spiking neurons. Yet even for basic cognitive functions, such as the ability to make decisions or prepare and execute a voluntary movement, the gap between spikes ... -
The functional connectome across spatiotemporal scales: How integrating fMRI and (i)EEG changes our understanding of the human brain
(2021-03-08)The view of human brain function has drastically shifted over the last decade, owing to the observation that the majority of brain activity is intrinsic rather than driven by external stimuli or cognitive demands. Specifically, ...
