Objective computerized evaluation of normal patterns of facial muscles contraction.

Unlabelled: Different methods used to evaluate the movements of the face have many degrees of subjectivity and reliability. The authors discuss the ease of using these methods in clinical practice or their accuracy in scientific research.

Aim: To obtain the standard for normal facial muscles movements using an objective method - the Vicon system.

Middle-latency auditory responses in neurological diseases.

Unlabelled: The presence of middle-latency evoked auditory potentials allows for integrity evaluation of both peripheral and the central auditory systems, and also, that of the nucleus and auditory pathways of sub-cortical region. They have also been used to study alterations of these structures in different neurological diseases.

Aims: the aim of this study is to verify the latency of the middle-latency evoked auditory potentials and detect the presence of any deflections in subjects with neurological diseases.
