Spectral-Temporal Receptive Fields of Nonlinear Auditory Neurons Obtained Using Natural Sounds
The stimulus–response function of many visual and auditory neurons has been described by a spatial-temporal receptive field (STRF), a linear model that for mathematical reasons has until recently… Expand

Feature analysis of natural sounds in the songbird auditory forebrain.
Although understanding the processing of natural sounds is an important goal in auditory neuroscience, relatively little is known about the neural coding of these sounds. Recently we demonstrated… Expand

A New Multineuron Spike Train Metric
TLDR
We propose an extension of the Victor-Purpura spike train metric to a multineuron metric. Expand

Invariance and Sensitivity to Intensity in Neural Discrimination of Natural Sounds
Intensity variation poses a fundamental problem for sensory discrimination because changes in the response of sensory neurons as a result of stimulus identity, e.g., a change in the identity of the… Expand

Seasonal Plasticity of Precise Spike Timing in the Avian Auditory System
Vertebrate audition is a dynamic process, capable of exhibiting both short- and long-term adaptations to varying listening conditions. Precise spike timing has long been known to play an important… Expand

Cortical interference effects in the cocktail party problem
Humans and animals must often discriminate between complex natural sounds in the presence of competing sounds (maskers). Although the auditory cortex is thought to be important in this task, the… Expand

Cortical Gamma Rhythms Modulate NMDAR-Mediated Spike Timing Dependent Plasticity in a Biophysical Model
TLDR
Spike timing dependent plasticity (STDP) has been observed experimentally in vitro and is a widely studied neural algorithm for synaptic modification. Expand

Spatial unmasking of birdsong in zebra finches (Taeniopygia guttata) and budgerigars (Melopsittacus undulatus).
Budgerigars and zebra finches were tested, using operant conditioning techniques, on their ability to identify a zebra finch song in the presence of a background masker emitted from either the same… Expand

Spike timing and the coding of naturalistic sounds in a central auditory area of songbirds
TLDR
In nature, animals encounter high dimensional sensory stimuli that have complex statistical and dynamical structure. Expand

Spatial unmasking of birdsong in human listeners: energetic and informational factors.
TLDR
Spatial unmasking describes the improvement in the detection or identification of a target sound afforded by separating it spatially from simultaneous masking sounds through mechanisms that are not specific to speech. Expand
