ALL IN THE MIND Reading Explorer 3-10A In an experiment to test intelligence, a bottlenose dolphin guides a ball through a maze of pipes. WARM UP ALL IN THE MIND WARM UP Before You Read Before You Read What’s on your mind? The ancient Egyptians thought so little of the brain that when a king died, they removed the brain from his body and threw it away. The Egyptians presumed, like many people before and after them, that consciousness - your mind and your thoughts - existed in the heart. Now we know that the mind is a product of the brain, but how exactly does this 1.5-kilo piece of matter create a mind that allows you to think about yourself, experience happiness and anger, or remember events that happened 20 minutes or 20 years ago? This isn't a new question. Today, however, powerful new techniques for visualizing the sources of thought, emotion, behavior, and memory are transforming the way we understand the brain and the mind it creates. ancient Egyptians 古埃及人 emotion n. 情感 ; 情绪 ; 激情 transform v.使改观; 使改变形态 What’s on your mind? Have you ever stopped and thought, "What's wrong with me today? I just don't feel like myself"? Perhaps you were more tired or worried than usual - but somehow, you knew that something was different about you. This self-awareness - the ability to think about yourself and how you're feeling - is an important part of being human. This part of your mind has its origins in the prefrontal cortex - a region of your brain just behind your forehead that extends to about your ears. Before this area began to function (around age two), you didn't understand that you were a separate individual with your own identity. As this part of your brain developed, you became more aware of yourself and your thoughts and feelings. The temporal lobe - a part of the brain associated with perception and speech - helped you understand and put into words these thoughts and feelings. but somehow 但不知怎么的 function n.功能 ; 函数 ; 作用 identity n.相同; 身份; 一致; 特征 What’s on your mind? Perhaps one of the most important factors involved in shaping our identity is memory. What exactly is a memory? Most scientists define it as a stored pattern of connections between neurons in the brain. Every feeling you remember and every thought you think alters the connections within the vast network of brain cells, and memories are reinforced, weakened, or newly formed. neuron n.神经元 A neuron is a cell that is part of the nervous system. Neurons send messages to and from the brain. vast adj.巨大的; 大量的 reinforced v.加强; 加固 What’s on your mind? Most people's earliest memories reach back to about age three or so. Very few people remember anything before this time because the part of the brain that helps form long-term memories (the hippocampus) was not yet fully developed. This doesn't mean earlier memories don't exist in your mind, though. Some scientists believe highly emotional memories, especially those associated with intense fear, might be stored in another structure in the brain (the amygdala) that may be functional at birth. Although these memories are not accessible to the conscious mind, they might still shape the way we feel and behave, even into adulthood. structure n. 结构 ; 构造 ; 体系 conscious adj.有意识的; 意识到 adulthood n. 成年; 成年期 What’s on your mind? But where do our emotions come from, and how do they shape the people we are and the way we perceive the world? Forty years ago, psychologist Paul Ekman demonstrated that facial expressions used to exhibit certain emotions are recognized by people everywhere. Ekman suggested that these emotions and their corresponding facial expressions evolved to help us deal quickly with situations that can affect our welfare. demonstrated v.证明; 演示 evolve v.进化; (使)逐渐形成，逐步发展 welfare n.福利 What’s on your mind? Though humans may share certain emotions and recognize them in others, we don't all have the same emotional response to every situation. In fact, most emotional responses are learned and stored in our memories. The smell of freshly cut grass, for example, will generate happy feelings in someone who spent enjoyable childhood summers in the countryside, but not in someone who was forced to work long hours on a farm. Once an emotional association like this is made, it is very difficult to reverse it. "Emotion is the least flexible part of the brain, says Ekman. But we can learn to control our emotions by becoming consciously aware of their underlying causes and by not reacting automatically to things in our environment. smell of 气味 ; 带有…气味 ; 带有某种令人不快的迹象 flexible adj.灵活的;柔韧的;有弹性的 What’s on your mind? But is it really possible to control our emotions? Researcher Richard Davidson has demonstrated that people who experience negative emotions display activity in their right prefrontal cortex. In those with a more positive perspective, the activity occurs in the left prefrontal cortex. Could we, Davidson wondered, control this activity and shift our mental state away from negative feelings toward a calmer state of mind? perspective n.观点; 态度; shift v.转移;换 What’s on your mind? To answer this question, Davidson worked with a group of volunteers in the United States. One group received eight weeks of training using different meditation and relaxation techniques, while another group did not. By the end of the study, those who had meditated had accomplished their goal: They showed a clear shift in brain activity toward the left, "happier" frontal cortex. For centuries, people have studied the brain, but it is only in recent years that we have really started to learn how it works. Nevertheless, there is still a long way to go before we understand our mind's many complexities. meditation n.冥想 frontal cortex 额叶皮层 Post -Reading Reading Comprehension Reading Comprehension Reading Comprehension 1 2 3 4 Reading Skill Reading Skill Self-awareness human two identity Long-term responses reverse meditation Reading Skill The smell of freshly cut grass, for example, will generate happy feelings in someone who spent enjoyable childhood summers in the countryside, but not in someone who was forced to work long hours on a farm. I feel happy when I hear seagulls because it reminds me of my childhood at the beach. I also like the smell of rain on hot earth because that reminds me of how we would wait excitedly for the rain to come in the middle of the summer.
