Midbrain dopamine neurons encode a quantitative reward prediction error signal. Si bien los resultados apoyan la hipótesis propuesta, es necesario realizar futuros experimentos para determinar con mayor precisión el correlato neuroquímico del incremento de CSPc en animales con AA.īayer, H. No se halló CSPc en los animales que recibieron haloperidol, mientras que en los sujetos con salina se observó en un ensayo. Se administró haloperidol a animales con AA (0.1 mg/kg, i.p.) antes de los ensayos de incremento del refuerzo y salina a un grupo control. El objetivo de este estudio fue evaluar si este efecto está asociado a la hiperactividad dopaminérgica. En estudios previos las ratas con AA mostraron un incremento del Contraste Sucesivo Positivo consumatorio(CSPc, i.e, mayor consumo de una solución azucarada al 32%, 24 hs después de tener acceso a una solución al 4%), respecto de animales sin AA. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.Las ratas expuestas a aislamiento adolescente (AA) muestran alteraciones neurológicas y conductuales en la adultez, muchas de ellas relacionadas con cambios en la respuesta ante reforzadores apetitivos. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file.
