Document Summary
Philosophical underpinnings: dualism: mind and brain are separate entities, modern view: mind is an activity of the brain. Integration of neural activity from different cortical sites (the binding problem) Recursive comparison of information via thalamocortical circuits. What does it mean to be conscious : self awareness: Sensory experience comes into the brain; consciousnss requires that you can distribute that information. Visual pathways involved in conscious and blindsight. When we name a picture, for example, visual regions are thought to be in phase with language regions, including broca"s area: brain rhythms have been generally suggested to link the cellular networks in the cortex and thalamus. This may also be an important mechanism for consciousness (the binding problem). Action can be controlled subconsciously: even in the absence of form vision (form agnosia) Brain activity before conscious awareness of intention to move- readiness potential.
