The purpose of this study is to test the accuracy of using an imaging technique called breath-holding functional magnetic resonance imaging (BH fMRI) in addition to the standard imaging test described above. This study will allow the researchers to find out whether using BH fMRI in combination with the standard approach is the same as, better, or worse than the standard approach used alone.

Inclusion Criteria:

Health Volunteers

• Volunteers between the ages of 18 and 80 years
• Volunteers must be able to perform the language paradigms on cue while inside the scanner Patients
• Patients between the ages of 18 and 80 years
• Patients must be able to perform the language paradigms on cue while inside the scanner
• Women of child bearing potential must have a negative pregnancy test prior to the study intervention (Serum or Urine)
• Patients diagnosed with primary glial neoplasm, meningioma and metastasis (from prior histology) or must be suspected to have primary glial neoplasm, meningioma and metastasis on imaging (to be confirmed by post-operative histology).
• Patient"s location of the tumor must involve the expected location of Broca"s area (left pars opercularis and/or pars triangularis), or the expected location of the primary motor area (the pre-central gyrus). This determination will be made on the basis of a pre-operative MRI by a fellowship-trained Neuroradiologist
