区域8B可以被视为前额叶皮层或前运动皮层的一部分。以前的研究表明，参与8B区在眼睛和耳朵的运动控制和听觉知觉。在这份报告中，我们研究了三只猕猴的139个神经元，32个神经元表现出与环境听觉刺激有关的活动。15个具有听觉特征的细胞（15/32）在视觉注视执行过程中出现抑制的放电。其余107个单位表现出复杂或无法确定的行为。听觉环境细胞的存在，其活动与人的声音有关（研究人员），表明8B区可能是一个涉及听觉跨通道关联的区域，在自然行为中。视觉注视过程中的抑制效应表明，8B区是抑制网络的一部分，阻止与所有听觉刺激相关的注视转移。这可能是在注视期间注意力的参与可能影响听觉感知的结果。这两个方面表明，8B区参与听觉和定向过程的高级认知过程。
Area 8B may be treated as part of either the prefrontal cortex or the premotor cortex. Previous investigations showed an involvement of area 8B in both eye and ear motor control and in auditory perception. In this report, we Studied 139 neurons in three macaque monkeys of these., 32 neurons showed an activity related to environmental auditory stimuli. Fifteen cells with auditory characteristics (15/32) presented a firing discharge inhibited during the execution Of Visual fixation. The remaining 107 units presented complex or indefinable behaviour. The presence of auditory environmental cells which activity is related prevalently to the voice of persons (researchers) suggests that area 8B may be an area involved in auditory cross-modal association, in natural behaviour. The inhibitory effects during Visual fixation suggest that area 8B is part of the inhibitory network preventing the gaze shift in relation to ail auditory Stimulus. This may be the consequence of the engagement of attention during fixation that may affect the auditory perception. Both aspects indicate that area 8B is involved in high cognitive processes in auditory and orienting processes.
