Consciousness: from philosophy to neuroscience
Seminar organized by Daniel Kiper & Guests

   Fall semester 2021

Location: Y35 F 32

Due to the corona situation, this course will be given both live and online. The recorded zoom sessions will be posted on this webpage for those who miss the "live" version. Thanks for your understanding.

The course happens simultaneously online and in person. Here is the Zoom link:


    Schedule: Thursday, 5.15-7.00pm

This course is intended for all students interested in the topic of consciousness and the NCC, i.e. the Neural Correlate of Consciousness.

The course's main language is english, but discussions and questions in german are also possible.

The course will be recorded and the podcasts will be posted here.


Most topics will be covered in articles and notes available on this web site, or that will be distributed during the course.

Here is a useful book "Philosophy of mind: a beginner's guide" by I. Ravenscroft that has been cleaned up and is searchable. In German, and in English

Successful completion of the course yields three credits, the details of the evaluation modalities will be posted here.

23.9: Introduction

30.9: Qualia
Here are the slides

Unfortunately, the recording did not should not happen again. The slides are self-explanatory, so no worries.
Here is information about the Sussex conference I talked about:

We are holding an interdisciplinary online conference on “Perception and Consciousness: From Biological to Computational Approaches*” to take place next week on the 7th  and 8th of October 2021 between 1pm – 5:30pm UK Time each day.

Registration to Attend

We are part of the Leverhulme Doctoral Scholarship Programme 'From Sensation and Perception to Awareness' at the University of Sussex. The programme is directed by Professor Jamie Ward and Professor Anil Seth and brings together researchers and doctoral students from across neuroscience, philosophy, psychology, robotics, and the arts, with the aim of advancing our understanding of interactions between sensation, perception, and awareness in humans, animals, and machines. Therefore, with this conference we aim to bring together a group of scientists who can offer a wide perspective on perception and consciousness.

If you are interested in *attending* the conference, here is the registration link.

7.10 The hard problem, free will. Here are the slides
Here is the recording.

14.10 NCC: Visual experiments
Here is the recording

21.10 End of visual experiments
Here is the recording
Here is the first assignement, due on Thursday, Nov. 5, 2021, 5pm at the latest.
Just send you essay in PDF format to me ( The essay can be maximum 200 words (I will not read longer ones:-).
Here is the theme:
"If you had methods that can show you the complete brain activity with millisecond and micrometer resolutions, what experiment would you do to see if free will really exists or not? Briefly describe the experiment and explain which conclusion would follow from which results (i.e. which result would lead you to conclude that free will exist, which one that it doesn't)".

28.10: Electrical stimulation, patients and more...
Unfortunately, the recording did not work (only 6 seconds were resorded). I think it is because I exceeded to quota. It is fixed and should not happen anymore.

4.11 End of "patients etc"
Here is the recording (yes, it worked....).

11.1 Baar's global workspace
Here is the recording

18.11 Synesthesia and hallucinations
Here is the recording.

25.11 Discussion round!
Here is the recording

Computational model, part I. A. Needergard
Here is the recording.

Here is the next essay question, due next week (Thursday 9.12, 5pm)
"In the Baar's theater metaphor, what would be the neural equivalent of the costumes worn by actors/actresses in the theater. And secondly, what would be the theater equivalent of the dreams that our brain generates"
Again, max. 200 words, and send it to me (, as PDF, with a file name containing your name. Thanks and have fun.
