Our ability to perceive multiple objects is mysterious. Sensory neurons are broadly tuned,
producing potential overlap in the populations of neurons activated by each object in a …

How neural representations preserve information about multiple stimuli is mysterious.
Because tuning of individual neurons is coarse (eg, visual receptive field diameters can …

Sensory receptive fields are large enough that they can contain more than one perceptible
stimulus. How, then, can the brain encode information about each of the stimuli that may be …

Neural encoding, or neural representation, is a field in neuroscience that focuses on
characterizing how information is encoded in the spiking activity of neurons. Currently, little …

Understanding how neurons encode multiple simultaneous stimuli is a fundamental
question in neuroscience. We have previously introduced a novel theory of stochastic …

How multisensory cues affect processing in early sensory brain areas is not well understood.
The inferior colliculus (IC) is an early auditory structure that is visually responsive (;,), but …

How we distinguish multiple simultaneous stimuli is uncertain, particularly given that such
stimuli sometimes recruit largely overlapping populations of neurons. One commonly …

The inferior colliculus (IC) is an auditory midbrain nucleus essential to the perception of
sound frequency and the localization of sound source; yet it remains unclear how the firing …

This dissertation investigates the application of nonparametric mixture models in hypothesis
testing and high-dimensional covariance matrix estimation, where uncovering complex and …

We are interested in how populations of neurons coordinate to encode information from
multiple simultaneously presented stimuli. We conjecture that information about each …
