High-density multi-fiber photometry for studying large-scale brain circuit dynamics

Y Sych, M Chernysheva, LT Sumanovski… - Nature methods, 2019 - nature.com
Animal behavior originates from neuronal activity distributed across brain-wide networks.
However, techniques available to assess large-scale neural dynamics in behaving animals …

Fiber-optic implant for simultaneous fluorescence-based calcium recordings and BOLD fMRI in mice

F Schlegel, Y Sych, A Schroeter, J Stobart, B Weber… - Nature protocols, 2018 - nature.com
Despite the growing popularity of blood oxygen level–dependent (BOLD) functional MRI (fMRI),
understanding of its underlying principles is still limited. This protocol describes a …

[PDF][PDF] Sensory and behavioral components of neocortical signal flow in discrimination tasks with short-term memory

Y Gallero-Salas, S Han, Y Sych, FF Voigt, B Laurenczy… - Neuron, 2021 - cell.com

Basomedial amygdala activity in mice reflects specific and general aversion uncontrollability

…, M Baer, H Sigrist, E Sautter, Y Sych… - European Journal of …, 2022 - Wiley Online Library
Learning adaptive behaviour to control aversion is a major brain function. Detecting the
absence of control is also important, although chronic uncontrollable aversion can impact …

[HTML][HTML] Striatum-projecting prefrontal cortex neurons support working memory maintenance

M Wilhelm, Y Sych, A Fomins… - Nature …, 2023 - nature.com
Neurons in the medial prefrontal cortex (mPFC) are functionally linked to working memory (WM)
but how distinct projection pathways contribute to WM remains unclear. Based on optical …
