It is shown that preliminary ablation of the septum lucidum (the rat group II) leads to a considerable (up to 1000 presentations) and prolonged (up to one year) worsening of the elaboration of time intervals estimation, as compared to intact animals and does not significantly influence the conditioned reflexes to time stabilized before the operation (the rat group I). The great worsening of time intervals estimation is due to disturbance of the very mechanism of the reflex to time. Differences are discussed between the two groups of the operated rats. The septum ablation does not affect the state of conditioned reflexes to present stimuli. In the greater part of the postoperative rats a lowering of alimentary motivation is observed that may be secondarily accompanied by a disturbance of time intervals estimation.
结果表明，与未做手术的动物相比，预先切除透明隔（大鼠第二组）会导致时间间隔估计能力显著恶化（多达1000次呈现）且持续时间延长（长达一年），并且对手术前已稳定的时间条件反射没有显著影响（大鼠第一组）。时间间隔估计能力的大幅恶化是由于对时间反射机制本身的干扰。文中讨论了两组手术大鼠之间的差异。透明隔切除不影响对当前刺激的条件反射状态。在大部分术后大鼠中观察到进食动机降低，这可能继而伴随着时间间隔估计的紊乱。
