Brain activation sequences.
OBJECTIVE: Reported brain abnormalities in anatomy and function in psychiatric and neurological patients led to a project based on qualitative electroencephalography examination and analysis in an attempt to find specific brain derived pattern--or sequence of brain locations involved in processing various stimuli--both visual and auditory.
METHODS: Specialized software called Brain Activation Sequences was built according to our team member specifications (M.S.). The software utilizes event related potentials recorded during cognitive/emotion processing in participants (healthy controls, neurological patients and psychiatric patients) to calculate the sequence of brain areas using nonlinear and linear algorithms.
RESULTS: Results show significant differences in activation patterns between patients and healthy controls as well as significant similarities within the groups of patients and controls in both performed testing experiments....
