I would love to see the topics of sleep and dreams, emotions and feelings, language and thoughts, and learning and memory.
Also, a series about the fundamentals of neuroscience would be highly interesting - the brain, the nervous system, genes and neurons... (maybe even neural circuits).
Moreover, I would like you to discuss the topic of neuroimaging (techniques such as fMRI, MRI, PET, EEG).
And especially because of your specialization in vision and sight, a month about visual processing would be awesome.
