On the neurophysiology of consciousness: Part II. Constraining the semantic problem
1Department of Neurological Surgery, University of Southern California, Los Angeles 90033, USA.
Subjective awareness (C) is proposed to depend on the intralaminar nuclei of the thalamus (ILN). The internal structure and external relations of ILN are key to enabling subjective awareness.
Area of Science:
- Neuroscience
- Philosophy of Mind
- Cognitive Science
Background:
- Subjective awareness, termed 'C', is a complex phenomenon.
- Previous work (Part I) introduced the hypothesis linking C to the thalamus.
- This essay builds upon foundational concepts and semantic considerations.
Purpose of the Study:
- To elaborate on the hypothesis that subjective awareness depends on the intralaminar nuclei of the thalamus (ILN).
- To explore the semantic and philosophical underpinnings of this proposal.
- To provide detailed consideration of propositions 0, 1, and 2 from Part I.
Main Methods:
- Review of relevant material from Part I.
- Detailed examination of semantic aspects related to subjective awareness.
- Philosophical analysis of core propositions concerning ILN and C.
Main Results:
- The internal structure and external relations of ILN are presented as critical factors for subjective awareness.
- Propositions 0, 1, and 2 are analyzed in depth, supported by semantic and philosophical arguments.
- The dependence of subjective awareness (C) on ILN is further substantiated.
Conclusions:
- The intralaminar nuclei of the thalamus (ILN) are essential for subjective awareness (C).
- Understanding the intricate structure and connections of ILN is crucial for explaining consciousness.
- This work provides a deeper philosophical and semantic foundation for the ILN-C hypothesis.

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
