Continuous odor profile monitoring to study olfactory navigation in small animals

no code implementations14 Jan 2023 Kevin S. Chen, Rui Wu, Marc H. Gershow, Andrew M. Leifer

Olfactory navigation is observed across species and plays a crucial role in locating resources for survival.

Neural signal propagation atlas of C. elegans

1 code implementation9 Aug 2022 Francesco Randi, Anuj K. Sharma, Sophie Dvali, Andrew M. Leifer

We conclude that both synaptic and extrasynaptic signaling drive neural dynamics on short timescales and that measurement of evoked signal propagation are critical for interpreting neural function.

Correcting motion induced fluorescence artifacts in two-channel neural imaging

no code implementations26 Apr 2022 Matthew S. Creamer, Kevin S. Chen, Andrew M. Leifer, Jonathan W. Pillow

Existing approaches for this correction, such as taking the ratio of the two channels, do not account for channel independent noise in the measured fluorescence.

Large-scale neural recordings call for new insights to link brain and behavior

1 code implementation26 Mar 2021 Anne E. Urai, Brent Doiron, Andrew M. Leifer, Anne K. Churchland

Neuroscientists today can measure activity from more neurons than ever before, and are facing the challenge of connecting these brain-wide neural recordings to computation and behavior.

Automatically tracking neurons in a moving and deforming brain

1 code implementation14 Oct 2016 Jeffrey P. Nguyen, Ashley N. Linder, George S. Plummer, Joshua W. Shaevitz, Andrew M. Leifer

Here we present an automated computer vision pipeline to reliably track populations of neurons with single neuron resolution in the brain of a freely moving C. elegans undergoing large motion and deformation.
