How reward and experience shape neural population dynamics in mouse visual cortex #neuroscience

How reward and experience shape neural population dynamics in mouse visual cortex
Learning reshapes cortical activity, but it remains unclear whether population-level changes primarily reflect exposure to sensory statistics or reward-driven assignment of behavioral relevance. We analysed calcium imaging data from mice exposed to the same visual environment with or without reward, and used tensor component analysis to separate within-trial dynamics from across-trial learning-related structure. Rewarded learning produced a distinct reorganisation of population geometry. After …

Trying to draft a kind of "graphical abstract" on visual prosthesis BCI options... brain implants with electrodes, ultrasound with optogenetics or nanoparticles, and noninvasive visual-to-auditory sensory substitution. Suggestions for improvement? #neuroscience
