Nonlinear Statistical Data Assimilation for HVC$_{\text{RA}}$ Neurons in the Avian Song System
With the goal of building a model of the HVC nucleus in the avian song system, we discuss in detail a model of HVCRA projection neurons comprised of a somatic compartment with fast Na and K currents and a dendritic compartment with slower Ca dynamics. We show this model qualitatively exhibits many observed electrophysiological behaviors. We then show in numerical procedures how one can design a...

متن کاملHVC Interneuron Properties from Statistical Data Assimilation
Data assimilation (DA) solves the inverse problem of inferring initial conditions given data and a model. Here we use biophysically motivated HodgkinHuxley (HH) models of avian HVCI neurons, experimentally obtained recordings of these neurons, and our data assimilation algorithm to infer the full set of parameters and a minimal set of ionic currents precisely reproducing the observed waveform i...
متن کاملTitle: Distributed and Selective Auditory Representation of Song Repertoires in the Avian Song System Avian Song Repertoire Representation in Nucleus Hvc
For many songbirds, the vocal repertoire comprises acoustically distinct songs that are flexibly used in various behavioral contexts. To investigate how these different vocalizations are represented in the song neural system, we presented multiple song stimuli while performing extracellular recording in nucleus HVC in adult male song sparrows Melospiza melodia, a species known for its complex v...
متن کاملSynaptic interactions underlying song-selectivity in the avian nucleus HVC revealed by dual intracellular recordings.
Stimulus-dependent synaptic interactions underlying selective sensory representations in neural circuits specialized for sensory processing and sensorimotor integration remain poorly understood. The songbird telencephalic nucleus HVC is a sensorimotor area essential to learned vocal control with one projection neuron (PN) type (HVC(RA)) innervating a song premotor pathway, another PN (HVC(X)) i...
