Abstract

This study addresses the question of how previous choices affect the interaction between the basal ganglia and anterolateral motor cortex (ALM) during a cued auditory dual choice task in mice. We did Ca imaging in the ALM and used ChR2 for excitation of neurons in the indirect pathway. We discovered that optogenetic manipulation's impact varied with the animal's past decisions. Notably, trials following the same choice were less influenced by optogenetic stimulation, suggesting a form of neural adaptation or memory effect within the circuit. Our analysis shows distinct activity patterns in the ALM based on prior choices, with a pronounced difference in the magnitude of neuronal response. These findings highlight the importance of historical choice information in shaping future decisions and suggest a sophisticated mechanism by which the corticostriatal circuit adjusts to previous outcomes, enhancing our understanding of decision-making processes and neural plasticity.
