             abstract = "In this work we show that the secondary cosmic ray variations 
                         (neutron and muon) depends on the solar structures observed in the 
                         interplanetary medium. We analyzed interplanetary and cosmic 
                         ray-ground-based observations from 2001 to 2004. In order to do 
                         this, interplanetary magnetic field and solar wind plasma 
                         parameters, registered by the instruments on board the Advanced 
                         Composition Explorer - ACE satellite, and ground based cosmic ray 
                         data of the neutron monitors maintained by the Bartol Research 
                         Institute of the Delaware University, United States, and the muon 
                         scintillator telescope, installed in the Southern Space 
                         Observatory - SSO/RSU/INPE-MCT in S{\~a}o Martinho da Serra, 
                         Brazil, were used.We classified the interplanetary structures as: 
                         (a) interplanetary coronal mass ejection, (b) interplanetary 
                         shocks, (c) magnetic clouds, (d) corotating interaction regions, 
                         and (e) complex structures.We observed that during the passage of 
                         magnetic clouds, cosmic ray decreases are more intense than during 
                         the others structures. Thereafter, the cosmic ray response to the 
                         corotating interaction regions passage is the less intense. In 
                         spite of all efforts, it is not possible to satisfactorily explain 
                         the cosmic ray response during the passage of the interplanetary 
                         structures. Several models attribute the cosmic rays decreases to 
                         the particles scattering in the magnetic field turbulent area 
                         between the shock front and the ejection.",
