Diseño e implementación de dos sistemas de monitoreo para la evaluación de la actividad ansiolítica in vivo en ratas (Rattus Norvegicus).

Abstract

For the present work, two monitoring systems were designed and implemented for the evaluation of anxiolytic activity in vivo in rats. These systems made it possible to visualize an application for each one respectively, they were created by the author called Clear/Dark and Labyrinth, various events to be measured. These systems were developed by blocks of: input, processing, storage and output (user interface). In the first block with the help of the Sharp sensors, distance data was collected, the second block processed the data obtained, which are transmitted through the NRF24L01 module to its receiver, for this block the Mega and Uno Arduinos were used. Being this the main board; in the third block, vectors were created for the storage of the emitted measurements, at this point the Matlab Software was used specifically for the graphical interface to process the information received by the receiver module NRF24L01 and be able to be visualized in the fourth block, in the final stage the application was programmed to show in addition to the data already mentioned a graph of the displacements. From the tests carried out, it is concluded that the synchronization time between the two platforms is 2 seconds. It has an error in the crosses of 0.467 points in the LDM and 0.333 points in EPM due to the sensitivity of the sensors. It is concluded that the implemented systems can become an aid tool for the development of anxiolytic tests. It is advisable to use artificial vision to perform image processing with the help of specialized software as well as the use of a single hardware platform with greater transmission capacity to avoid interruptions in sending data.
