Area of Science:

• Neuroscience
• Computational Neuroscience
• Systems Neuroscience

Background:

• Investigating orientation tuning dynamics in the primary visual cortex is crucial for understanding visual processing.
• Experimental methods often require theoretical underpinnings for accurate interpretation.

Purpose of the Study:
