Emotional stimuli capture attention, thus making it more likely that we will look at these stimuli than at other objects in our environment. This emotional advantage is also seen at the neural level-areas of the brain related to attention show more activity when perceiving emotional than neutral stimuli. However, our emotional responses do not end there. Instead, we often produce some sort of behaviour in response to the emotional stimuli. Recent brain-imaging studies have shown that emotion enhances activity in regions related to movement planning in the same way that it influences areas related to attention. A similar pattern has been observed in cells in the spinal cord, suggesting that emotion helps promote neural networks that will put us in a state of "action preparedness." This Discovery Grant will fund Dr. Stephen Smith's Affective Neuroscience Laboratory at the University of Winnipeg. Dr. Smith's research team performs cutting-edge research that attempts to identify the networks in the brain and spinal cord that influence emotion-movement interactions. In the current studies, Dr. Smith and his students will use functional magnetic resonance imaging to measure activity in the brain and the spinal cord. The data from these scans will provide the most complete depiction of the neural architecture of emotional experiences currently available, and may have applications for our understanding of the neuroscience behind numerous psychological disorders.

情绪刺激会吸引注意力，因此我们更有可能看到这些刺激，而不是周围环境中的其他物体。 这种情绪优势也可以在神经层面上看到，当感知情绪刺激时，大脑中与注意力相关的区域比中性刺激表现出更多的活动。 然而，我们的情绪反应并没有就此结束。 相反，我们经常会对情绪刺激做出某种行为反应。 最近的大脑成像研究表明，情绪会增强与运动规划相关的区域的活动，就像它会影响与注意力相关的区域一样。 在脊髓细胞中也观察到了类似的模式，这表明情绪有助于促进神经网络，使我们处于“行动准备状态”。" 这项发现补助金将资助温尼伯大学斯蒂芬·史密斯博士的情感神经科学实验室。 史密斯博士的研究小组进行了尖端研究，试图确定大脑和脊髓中影响情绪运动相互作用的网络。 在目前的研究中，史密斯博士和他的学生将使用功能性磁共振成像来测量大脑和脊髓的活动。 这些扫描数据将提供目前可用的情绪体验神经结构的最完整描述，并可能应用于我们对许多心理障碍背后的神经科学的理解。
