Published in 2019 at "Hippocampus"

DOI: 10.1002/hipo.23080

Abstract: Prolonged increases in excitation can trigger cell‐wide homeostatic responses in neurons, altering membrane channels, promoting morphological changes, and ultimately reducing synaptic weights. However, how synaptic downscaling interacts with classical forms of Hebbian plasticity is still… read more here.

Published in 2021 at "Methods in molecular biology"

DOI: 10.1007/978-1-0716-0830-2_7

Abstract: Optogenetics enables experimental control over neural activity using light. Channelrhodopsin and its variants are typically activated using visible light excitation but can also be activated using infrared two-photon excitation. Two-photon excitation can improve the spatial… read more here.

Published in 2018 at "Nature Communications"

DOI: 10.1038/s41467-018-04840-2

Abstract: Serotonin has widespread, but computationally obscure, modulatory effects on learning and cognition. Here, we studied the impact of optogenetic stimulation of dorsal raphe serotonin neurons in mice performing a non-stationary, reward-driven decision-making task. Animals showed… read more here.
