Study Arms:
- COPD Patients (Type: EXPERIMENTAL): C.O.P.D. patients: Presence of a post-bronchodilator forced expiratory volume at one second (FEV1) / forced vital capacity (FVC) \< 0.70 with symptoms as dyspnea, chronic cough, chronic sputum production~Biofeedback and Neurofeedback Training~Varenicline use for smoking cessation~Passive Control
- Asthma Patients (Type: EXPERIMENTAL): Asthma patients: Presence of 2 or more of symptoms of airflow obstruction (cough, wheezing, dyspnea). Airflow obstruction at least partially reversible demonstrated by spirometry with FEV1 increased by \>12% following b2 agonist inhalation) or evidence of bronchial hyperresponsiveness by metacholine provocation test (demonstrated by provocative concentration causing a 20% fall (PC20) \<8 mg or mannitol provocation test (with FEV1 decrease of 15%)~Biofeedback and Neurofeedback Training~Varenicline use for smoking cessation~Passive Control
- Smokers (Type: EXPERIMENTAL): Smokers will consist of a group of patients that are under the age of 35, unemployed and healthy according to a standard clinical evaluation.~Biofeedback and Neurofeedback Training~Varenicline use for smoking cessation~Sham Neurofeedback~Passive Control
