The multifaceted concept of impulsivity implies that different impulsivity aspects, mediated by different neural processes, influence behavior at different levels. The nucleus accumbens (NAc) is a key component of the neural processes regulating impulsivity. In this review, we discuss the findings of lesion studies in animals and functional imaging studies in humans focusing on the role of the ...

Phasic Nucleus Accumbens Dopamine Encodes

JONATHAN SUGAM: Phasic nucleus accumbens dopamine encodes risk-based decision making behavior (Under the direction of Regina M. Carelli) When deciding to act organisms must correctly evaluate the costs and benefits of action selection in order to optimize resources. Several factors influence the evaluation of reward value including the behavioral cost, the delay to, probability of, and magnitud...

Cómo Direccionar Más Allá del Primer MegaByte en el Modo Real de las PC

La situación anterior fue ocasionada por la regla que adoptó Intel, la cual consiste en ofrecer una rígida compatibilidad de sus nuevos productos con los que ya tenía comercializados anteriormente [3]. Las máquinas 80286 y superiores ejecutan todo el software desarrollado para las máquinas 8088 y 8086. En este modo real de trabajo la única diferencia aparente consiste en la velocidad del proces...
