Inclusion Criteria

For the Moebius Participants and congenital bilateral facial paralysis the following inclusion criteria are required for Part I of the study:
* Males and females between the ages of 18 and 65 years
* Normal visual acuity or corrected to normal vision
* The participants must be willing and able to participate in the measurements
* The participants must have given written informed consent to be included in the study
* Clinical diagnosis of Möbius Syndrome or congenital bilateral facial paralysis from a registered neurologist;For the Volunteer Control Participants for Part I, the following inclusion criteria are required:
* Males and females between the ages of 18 and 65 years
* Normal visual acuity or corrected to normal vision
* The participants must be willing and able to participate in the measurements
* The participants must have given written informed consent to be included in the study;We shall begin by scanning for Part II the first SIX fMRI suitable volunteers who apply. Depending on the results (see section 5.3) from this, this will determine how we will procede further with Part II.

* Those suffering from a neurological disorder not related to Möbius e.g. epilepsy, Parkinson*s disease, and Huntington*s disease.;For the Moebius Participants and congenital bilateral facial paralysis in Part II of the study the following criteria apply:
* Visual disorder that cannot be corrected through the use of corrective lenses to a level of 20-40 in both eyes (we have MRI safe glasses for a very broad range of prescriptions)
* Another significant CNS disorder (e.g. brain damage, epilepsy)
