[PDF][PDF] A circuit for gradient climbing in C. elegans chemotaxis

J Larsch, SW Flavell, Q Liu, A Gordus, DR Albrecht… - Cell reports, 2015 - cell.com
Animals have a remarkable ability to track dynamic sensory information. For example, the
nematode Caenorhabditis elegans can locate a diacetyl odor source across a 100,000-fold …

[HTML][HTML] Serotonin and the neuropeptide PDF initiate and extend opposing behavioral states in C. elegans

…, N Pokala, EZ Macosko, DR Albrecht, J Larsch… - Cell, 2013 - cell.com
Foraging animals have distinct exploration and exploitation behaviors that are organized into
discrete behavioral states. Here, we characterize a neuromodulatory circuit that generates …

[PDF][PDF] Neural circuitry for stimulus selection in the zebrafish visual system

AM Fernandes, DS Mearns, JC Donovan, J Larsch… - Neuron, 2021 - cell.com
When navigating the environment, animals need to prioritize responses to the most relevant
stimuli. Although a theoretical framework for selective visual attention exists, its circuit …

[PDF][PDF] Biological motion as an innate perceptual mechanism driving social affiliation

J Larsch, H Baier - Current Biology, 2018 - cell.com
Collective behavior, such as shoaling in teleost fish, is driven by the perceptual recognition
of conspecific animals. Because social interactions are mutual, it has been difficult to …

A single-cell resolution gene expression atlas of the larval zebrafish brain

…, M Al Kassar, N Mokayes, S Sherman, J Larsch… - Science …, 2023 - science.org
The advent of multimodal brain atlases promises to accelerate progress in neuroscience by
allowing in silico queries of neuron morphology, connectivity, and gene expression. We …

Oscillatory stimuli differentiate adapting circuit topologies

SJ Rahi, J Larsch, K Pecani, AY Katsov, N Mansouri… - Nature …, 2017 - nature.com
Biology emerges from interactions between molecules, which are challenging to elucidate
with current techniques. An orthogonal approach is to probe for 'response signatures' that …

[HTML][HTML] Visual recognition of social signals by a tectothalamic neural circuit

…, S Sherman, M Januszewski, H Baier, J Larsch - Nature, 2022 - nature.com
Social affiliation emerges from individual-level behavioural rules that are driven by conspecific
signals 1 , 2 , 3 , 4 – 5 . Long-distance attraction and short-distance repulsion, for example…

High-throughput imaging of neuronal activity in Caenorhabditis elegans

J Larsch, D Ventimiglia… - Proceedings of the …, 2013 - National Acad Sciences
Neuronal responses to sensory inputs can vary based on genotype, development, experience,
or stochastic factors. Existing neuronal recording techniques examine a single animal at …

MultiFocus Polarization Microscope (MF-PolScope) for 3D polarization imaging of up to 25 focal planes simultaneously

…, M McQuilken, SB Mehta, A Verma, J Larsch… - Optics express, 2015 - opg.optica.org
We have developed an imaging system for 3D time-lapse polarization microscopy of living
biological samples. Polarization imaging reveals the position, alignment and orientation of …

[PDF][PDF] Rapid effects of selection on brain-wide activity and behavior

C Pantoja, J Larsch, E Laurell, G Marquart, M Kunst… - Current Biology, 2020 - cell.com
Interindividual variation in behavior and brain activity is universal and provides substrates
for natural selection [1–9]. Selective pressures shift the expression of behavioral traits at the …
