Abstract:
An apparatus for obtaining magnetic resonance data representing functional brain activities of an examination subject, said apparatus comprising:a magnetic resonance data acquisition system;a stimulation unit for stimulating an examination subject in said magnetic resonance data acquisition system; anda control unit connected to said magnetic resonance data acquisition system and to said stimulation unit for operating said stimulation unit and said magnetic resonance data acquisition system by the executing executive sequences, said control unit having first control output for causing said stimulation unit to emit a stimulus perceivable by said examination subject, a second control output for supplying a pulse sequence to said magnetic resonance data acquisition system for operating said magnetic resonance data acquisition system to obtain magnetic resonance data from said examination subject after said stimulus, a third control output for emitting said magnetic resonance data, and an input interacting with said examination subject to obtain physical parameters from said examination subject during execution of said executive sequences and entering said physical parameters of said examination subject into said control unit for influencing at least one of said pulse sequence and said stimulus during execution of said executive sequences; anddisplay and processing means connected to said third control output for processing said magnetic resonance data to generate a time-resolved and location-resolved presentation of functional brain activities of said examination subject.
