Signal switching may enhance processing power of the brain

JM Groh, MN Schmehl, VC Caruso… - Trends in Cognitive …, 2024 - cell.com
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 …

Multiple objects evoke fluctuating responses in several regions of the visual pathway

MN Schmehl, VC Caruso, Y Chen, NY Jun, SM Willett… - Elife, 2024 - elifesciences.org
How neural representations preserve information about multiple stimuli is mysterious.
Because tuning of individual neurons is coarse (eg, visual receptive field diameters can …

Coordinated multiplexing of information about separate objects in visual cortex

NY Jun, DA Ruff, LE Kramer, B Bowes, ST Tokdar… - Elife, 2022 - elifesciences.org
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 …

Modeling Neural Switching via Drift-Diffusion Models

N Marco, JM Groh, ST Tokdar - arXiv preprint arXiv:2410.00781, 2024 - arxiv.org
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 …

[HTML][HTML] Spike Count Analysis for MultiPlexing Inference (SCAMPI)

Y Chen, JM Groh, ST Tokdar - bioRxiv, 2024 - pmc.ncbi.nlm.nih.gov
Understanding how neurons encode multiple simultaneous stimuli is a fundamental
question in neuroscience. We have previously introduced a novel theory of stochastic …

Visually-evoked activity and variable modulation of auditory responses in the macaque inferior colliculus

MN Schmehl, JL Herche, JM Groh - bioRxiv, 2024 - biorxiv.org
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 …

Multiple sounds degrade the frequency representation in monkey inferior colliculus

SM Willett, JM Groh - European Journal of Neuroscience, 2022 - Wiley Online Library
How we distinguish multiple simultaneous stimuli is uncertain, particularly given that such
stimuli sometimes recruit largely overlapping populations of neurons. One commonly …

Encoding of Concurrent Sounds in the Monkey Inferior Colliculus

SM Willett - 2020 - search.proquest.com
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 …

Multisensory integration, segregation, and causal inference in the superior colliculus

JT Mohl - 2020 - search.proquest.com
The environment is sampled by multiple senses, which are woven together to produce a
unified perceptual state. However, unifying these senses requires assigning particular …

[PDF][PDF] Patterns of neural correlations in V1 vary with the number of objects

NY Jun, DA Ruff, ST Tokdar, MR Cohen, JM Groh - bioRxiv, 2019 - marlenecohen.com
How the brain preserves information about more than one stimulus at a time remains poorly
understood. We recently showed that when more than one stimulus is present, single …
