Midline thalamic reuniens lesions improve executive behaviors

Highlights • Lesions of the nucleus reuniens improve prefrontal executive functions. • Rats with nucleus reuniens lesions become more attentive and less impulsive. • Nucleus reuniens lesions accelerate learning of stimulus–reward associations. • Enhanced attention does not necessarily lead to improv...
