Nerve impulses have to be at the heart of consciousness inasmuch as impulses contain the brains representation of information and create the synaptic field potentials. Thalamus-Can an ipx protocol be routed. The thalamus relays sensory impulses from receptors in various parts of the body to the cerebral cortex.

These branches end at junctions called synapses. It goes from the optic nerve to the thalamus and then to the visual cortex. Nerve impulses such as pain signals travel slower at 061ms.

For example the botulism toxin the active ingredient of Botox prevents vesicles which are carrying neurotransmitter molecules from fusing with the membrane and releasing its contents. Signals are sent from the optic nerve to the thalamus and then the visual cortex in the brain. The signals for taste hearing sight and touch are processed by the thalamus before being directed to the part of the brain-specific to the sense.
