Brief Summary
The purpose of this study is to evaluate the effects of a Zen meditation retreat (Sesshin) on psychophysiological parameters in healthy volunteers (regular meditators and non-meditators) and in cancer patients and to observe possible changes in the attentional circuitry (through functional Magnetic Resonance Imaging- fMRI) and in psychological tests (Beck Anxiety and Depression Inventories, Self-Compassion Scale, Mindfulness Attention Awareness Scale, Lipp Stress Scale for Adults).

Outcome Measures
Primary Outcomes (1)
To evaluate the neural correlates of performance modulation on an attention paradigm (the Stroop word-color task; SWCT) and on an emotional paradigm (the frustration paradigm) before and after a Zen meditation retreat.
2 years
Secondary Outcomes (1)
Anxiety, stress and depression symptoms, self-compassion feelings and mindfulness state will also be evaluated in healthy volunteers and cancer patients.

NO INTERVENTIONNo meditation (no intervention; keep regular activities) or a resting group (this group stays at the same place of the retreat group, but only to rest)
Interventions
Zen meditation retreat (7 days: 5 days from 5:30 to 9:30 plus one day for adaptation and the departure day). The program starts everyday at 5:30 and finish at 9:30. In silence, the volunteers perform seating and walking meditation, stretching exercises, eating and all tasks in mindfulness.
Eligibility Criteria
You may qualify if:
- Healthy volunteers:
- Men or women
- Left-handed or right-handed, as long as there are left-handed individuals in both groups for comparison
- Ages between 18 and 65
- No history of neurological or psychiatric problems, or use of controlled medication that might interfere with attention
- No symptoms of claustrophobia
- Written informed consent form to participate in the study
- Cancer patients:
- The same criteria that apply to healthy volunteers in addition to a diagnosis of neoplasia confirmed by biopsy
- Volunteers should be undergoing post-therapeutical control, have no cure criteria yet, and not have been submitted to radio- or chemotherapy in the last three months
You may not qualify if:
- Healthy Volunteers:
- Chemical dependence, including nicotine and alcohol
- Dementia or psychotic condition (established by a questionnaire)
- Depression or use of antidepressants
- Non-controlled severe organic disease that might interfere with the performance of the study, such as neoplasias, cardiopathies, digestive pathologies, diabetes mellitus type I or type II
- Neoplasias in the central nervous system
- Tremor or dystonia in cephalic segment that hinders the performance of the RMf study (tremor equal to or higher than 3 in each corporal segment, according to the UPDRS scale)
- Fulfillment of any criterion of contraindication for the MR exam (for instance, use of pacemaker; intracranial aneurism clip; cochlear implants)
- Presence of odontological devices that might disturb the magnetic field or any sources of variation of the magnetic susceptibility
- Presence of lesion in the encephalic parenchyma in the structural images. Exception is made to discreet punctiform areas in the white matter or a discreet reduction in the encephalic volume.
- Cancer patients:
- All the healthy volunteers, except for those that fit in the item: "non-controlled severe organic disease that might interfere in the performance of the study, such"
- The use of medication that acts on the central nervous system
