Dendritic sensitivity to the direction of synaptic firing mediated by inhibition; and, The effects of the release timecourse of neurotransmitter on synaptic transmission
… pass information within the context of larger neuronal ensembles. The first project focuses on information transfer between two neurons during synaptic transmission. The project was spurred by an initial observation that neuronal communication through synapses in young and developing neuronal …

Region-specific Mechanisms of Estrogen and Age on Neuronal Ensemble Activity During Spatial Navigation
… on activity, plasticity, and reliability of neuronal ensembles in several subregions of the hippocampus and striatum during spatial navigation using cellular and molecular techniques that take advantage of the kinetics of the immediate-early genes c-fos and Arc. Increased activation and …

Technologya nd Protocolsf or Translational Researchin ElectricalS timulation
… Mechanistic studies of electric field effects on neuronal ensembles first require electrophysiological characterization of a target brain region, such as the primary motor cortex that is involved in motor rehabilitation. Furthermore, when considering synaptic effects, it is important to consider …

Neural Population Dynamics Underlying Encoding of Time in the Cortico-Striatal Circuit
… perceived time intervals by forming coordinated neuronal ensembles, referred to as timing ensembles. Importantly, these neuronal ensembles exhibited dynamic engagement in neuronal activity on a trial-by-trial basis, rendering the timing ensembles as more reliable time encoders than individual …

Molecular mechanisms of memory formation : using activity regulated genes to identify active neural circuits
… to be represented in sparsely distributed neuronal ensembles within these larger structures. Currently, there are few tools that allow for the identification and manipulation of these ensembles, which has limited our understanding of the molecular and cellular processes underlying learning …

The mechanisms of reliable coding in mouse visual cortex
… movie dynamically altered the structure of interneuronal correlations. Movies with more naturalistic correlations typically recruited large neuronal ensembles that were weakly noise correlated. Using computational modeling, I discovered that these ensembles were able reduce shared noise through …

Neural activity in the posterior thalamus and hippocampus during time interval discrimination in rats
… were observed in both areas of the brain, and neuronal ensembles recorded from both areas conveyed significant amounts of information about the passage of time. A larger proportion of neurons conveyed temporal information based on monotonically changing activity profiles in the posterior …
