Neuroscience

Internal states, circuits, and the behaviour they produce.

in revision

Ethomics β€” What Is a Hungry Fly?

High-dimensional behavioural state benchmarking in Drosophila. The Espresso platform captures 17 behavioural metrics simultaneously across hundreds of flies. Used here to ask: does a serotonergic circuit manipulation produce genuine hunger, or just a superficially similar signature?

Current Biology 2017 β€” 48 citations

Intertemporal Choice

Dorsal raphe serotonergic neurons bidirectionally control delay discounting in Drosophila. Activation increases patience; silencing increases impulsivity. Effect is trade-off specific β€” not a motor or motivational confound.

PNAS 2020 β€” 119 citations

Noradrenergic Attention

Two distinct noradrenergic pathways implement different attentional control mechanisms in rodents. Selective lesions reveal a functional dissociation not apparent from anatomy alone.

Epitranscriptomics

Direct RNA nanopore sequencing pipeline for m6A and pseudouridine mapping in Drosophila serotonergic neurons. Does hunger change the RNA modification landscape?

Nature Neuroscience 2016 β€” 550 citations

Basolateral Amygdala Valence Circuits

Antagonistic negative and positive neurons of the basolateral amygdala encode opposing valence signals. Selective activation and silencing reveal a functional opponent architecture for fear and reward.

Octopamine, Dopamine, and the Hungry Fly Circuit

A mushroom-body output neuron (MBON11) integrates octopaminergic and dopaminergic signals to control hunger-motivated feeding in Drosophila. Octopaminergic VPM3/4 neurons are instructive but not required for hunger-driven feeding; dopaminergic PPL101 neurons are required but not instructive. MBON11 sits at the convergence point.
