Activity patterns of serotonin neurons underlying cognitive flexibility

S Matias, E Lottem, GP Dugué, ZF Mainen - Elife, 2017 - elifesciences.org
10.7554/eLife.20552.001 Serotonin is implicated in mood and affective disorders. However,
growing evidence suggests that a core endogenous role is to promote flexible adaptation to …

A gradual temporal shift of dopamine responses mirrors the progression of temporal difference error in machine learning

R Amo, S Matias, A Yamanaka, KF Tanaka… - Nature …, 2022 - nature.com
A large body of evidence has indicated that the phasic responses of midbrain dopamine
neurons show a remarkable similarity to a type of teaching signal (temporal difference (TD) error…

[HTML][HTML] Balanced activity in basal ganglia projection pathways is critical for contraversive movements

F Tecuapetla, S Matias, GP Dugue, ZF Mainen… - Nature …, 2014 - nature.com
The basal ganglia, and the striatum in particular, have been implicated in the generation of
contraversive movements. The striatum projects to downstream basal ganglia nuclei through …

SV Ramanaiah, CM Cordas, SC Matias, MV Reddy… - Biotechnology …, 2021 - Elsevier
In the present work, power generation and substrate removal efficiencies of long-term operated
microbial fuel cells, containing abiotic cathodes and biocathodes, were evaluated for 220 …

[HTML][HTML] In situ electrochemical characterization of a microbial fuel cell biocathode running on wastewater

SV Ramanaiah, CM Cordas, S Matias, LP Fonseca - Catalysts, 2021 - mdpi.com
The electrochemical features of microbial fuel cells’ biocathodes, running on wastewater,
were evaluated by cyclic voltammetry. Ex situ and in situ electrochemical assays were …
