dc.description.abstract | The frontal cortex (FC) plays a key role in higher-order cognitive functions and goal-directed behaviors. It is also crucial for the top-down modulation of sensory processing. In auditory tasks, FC interacts with the auditory cortex (AC) dynamically, which modulates the activity of AC to adaptively process and represent task-relevant signals. Task paradigm is an essential factor that influences frontal responses and top-down modulation. The attentional effect on sensory processing varies with different behavioral requirements and reward structures. Therefore, the neural mechanisms of top-down control may vary in different behavioral task paradigms. This study investigates how the neural representation of auditory stimuli in dorsolateral FC of the ferret is shaped by task and reward structure during different behavioral tasks. The results show that frontal neurons have differential responses and selectivity during the two behavioral tasks, and diverse temporal dynamics associated with task variables. | en_US |
