Noninvasive detection of bacterial biofilms using an insect olfactory brain-based gas sensor

This paper uses a locust-based olfactory system to detect bacterial biofilms by analyzing volatile organic compounds with high accuracy.

Data-Constrained Recurrent Network Neural Model Uncovers the Circuit Mechanism of Olfactory OFF Responses

The paper uses a data-constrained RNN model to uncover two distinct circuit mechanisms for olfactory OFF responses in locust antennal lobe neurons.

Detection of multiple per- and polyfluoroalkyl substances (PFAS) using a biological brain-based gas sensor

This paper develops a biological brain-based gas sensor using locust olfaction to detect and classify multiple PFAS with high accuracy.

Adaptation invariant concentration discrimination in an insect olfactory system

The paper investigates how locusts maintain odor intensity information despite neural adaptation in their olfactory system.

An insect brain-based bioelectronic neural sensor for the systemic detection and precise classification of endometriosis

This paper develops a bioelectronic sensor using an insect olfactory system to detect and classify endometriosis by analyzing volatile organic compounds from cell cultures.

Neural Circuit Dynamics for Sensory Detection

This paper uses optimization-based modeling to study how sensory networks, specifically in the olfactory system, track low-dimensional latent representations of stimuli through temporal dynamics.

Dynamic contrast enhancement and flexible odor codes

The paper investigates how odor-evoked responses in locusts vary with stimulus history and shows that a linear classifier matches behavioral decoding results.

Encoding the expectation of a sensory stimulus

The paper shows how neural circuits encode expectation of a sensory stimulus by reducing responses to repeated stimuli and increasing responses to unexpected ones.

Early warning signals regarding environmental suitability in the Drosophila antenna

The paper shows high-intensity odorant exposure harms flies and that a linear combination of ORN activities predicts intensity-dependent behavioral repulsion.
