Mirror neurons and the phenomenology of intersubjectivity 总被引:3,自引:0,他引:3
Dieter Lohmar 《Phenomenology and the Cognitive Sciences》2006,5(1):5-16
The neurological discovery of mirror neurons is of eminent importance for the phenomenological theory of intersubjectivity. G. Rizzolatti and V. Gallese found in experiments with primates that a set of neurons in the premotor cortex represents the visually registered movements of another animal. The activity of these mirror neurons presents exactly the same pattern of activity as appears in the movement of one's own body. These findings may be extended to other cognitive and emotive functions in humans. I show how these neurological findings might be “translated” phenomenologically into our own experienced sensations, feelings and volitions. 相似文献

Abstract: The paper aims at highlighting how our primary understanding of others’ actions is rooted in the mirror mechanism. To this end, the anatomical architecture of the mirror neuron system for action will be outlined as well as its role in grasping goals and intentions in others’ motor behaviour. One further step through the looking glass of social cognition will be referring to the ubiquitous emotional colouring of actions and considering its links with the motor domain. This will allow a clearer perspective on the mechanism underlying our abilities for emotional understanding and on cases in which these abilities are amiss, as in autistic spectrum disorders. 相似文献

相关线索能够诱发药物依赖者的心理渴求,而健康人不会对相关线索产生心理渴求。15名海洛因成瘾者和12名没有任何物质滥用的健康被试参与实验,收集了他们在观看相关线索与对照线索时的脑神经活动。结果发现,药物线索能够诱发戒断者更多脑区的活动,包括扣带回和楔前叶。两组被试在对照动作线索刺激诱发作用下,其颞叶、顶叶均出现了较为一致的活动。在用药动作线索诱发作用下,戒断组双侧颞中回、双侧顶下小叶、左侧顶上小叶和右侧额下回显示出显著活动,并且与对照动作线索激活脑区一致;健康组被试除枕叶-颞叶联合区外,没有出现显著的脑区活动。以上结果表明,用药动作线索诱发了海洛因戒断者颞中回、顶下小叶、额下回等镜像神经系统的活动,这些脑区对不同类型的相关线索十分敏感,它们可能通过对用药动作的心理模拟,参与了用药动作线索的快速自动化加工。 相似文献

A new class of visuomotor neuron has been recently discovered in the monkey's premotor cortex: mirror neurons. These neurons respond both when a particular action is performed by the recorded monkey and when the same action, performed by another individual, is observed. Mirror neurons appear to form a cortical system matching observation and execution of goal-related motor actions. Experimental evidence suggests that a similar matching system also exists in humans. What might be the functional role of this matching system? One possible function is to enable an organism to detect certain mental states of observed conspecifics. This function might be part of, or a precursor to, a more general mind-reading ability. Two different accounts of mind-reading have been suggested. According to ‘theory theory', mental states are represented as inferred posits of a naive theory. According to ‘simulation theory', other people's mental states are represented by adopting their perspective: by tracking or matching their states with resonant states of one's own. The activity of mirror neurons, and the fact that observers undergo motor facilitation in the same muscular groups as those utilized by target agents, are findings that accord well with simulation theory but would not be predicted by theory theory. 相似文献

Pigeons worked individually in a chamber containing a response key and a mirror. Pecking on the key was controlled by a multiple schedule in which a brief period of continuous food reinforcement alternated with a 5-minute period of extinction. Under baseline conditions, aggressive behavior (responding on the mirror) occurred at the onset of each extinction period. In Experiment I (acute drug administration), the aggressive behavior was decreased by doses of cocaine that had little or no effect on key pecking. Such food-reinforced responding was disrupted, however, by higher doses of cocaine. An attempt to mimic the disruptive drugs effects by a prefeeding manipulation was unsuccessful. In Experiment II (chronic drug administration), some tolerance developed to the disruptive effects of cocaine on the food-reinforced responding, except at the highest dose tested. There was no clear-cut indication of tolerance to the initial effect of cocaine on the aggressive behavior at any dose. 相似文献

示能性(affordance)概念解释了人的行为与物体功能之间互动、互补的关系。但是,有关示能性生理基础却很少被提及。镜像神经元的发现为示能性生理基础提供了可能的解释。文章根据研究将示能性分为结构示能性和功能示能性,探讨了不同示能性和镜像神经元之间的关系,并提出不同神经通路中的镜像神经元是示能性生理基础的结论。背-背侧分流中的镜像神经元是结构示能性的神经基础,而腹-背侧分流中的镜像神经元是功能示能性的神经基础。 相似文献

镜像神经元是意大利帕尔玛大学Rizzolatti等人在恒河猴大脑腹侧运动前皮层F5区发现的一种神经元。这种神经元在猴子操作和观察同一个指向某种目标的动作时(如伸手抓食物)皆被激活,似乎这种神经元映射了其它个体的动作,因此被命名为“镜像神经元”。镜像神经元通过具身的模拟把动作的执行和动作的知觉结合在一起,把观察过程与身体运动过程相融合,克服了二元论在身心之间所设置的障碍,为人们正确认识身心关系开辟了新的视角。 相似文献

ABSTRACT— Humans seem unique in their consideration of others' goals, motivations, intentions, and needs. But the human form of social awareness did not spring from nowhere; certain mechanisms shared across primates formed the foundation from which these processes derived. A review of recent nonhuman primate research points to particular ancestral mechanisms, including an interest in images moving in synchrony with self, a mirror neuron system that responds in the same way to actions made by the self and by others, and inherited social tolerance that provided the bases for social thinking. Still there is a gap in tracking social awareness from these basic beginnings to the ability to think about self and other with respect to intentions and goals. Comparative and clinical work will fill in this gap and will map brain processes onto social thinking. 相似文献

为了解流行性乙型脑炎(乙脑)患儿血清神经元特异性烯醇化酶(NSE)、S-100蛋白(S-100)、髓鞘碱性蛋白(MBP)含量变化及其临床意义,用酶联免疫吸附法检测100例乙脑患儿血清NSE、S-100、MBP含量变化。结果显示,乙脑组患儿血清NSE、S-100、MBP含量与对照组比较显著增高(P均〈0.01),增高程度与病情严重程度相平行(P〈0.01)。因此,血清NSE、S-100、MBP含量测定对乙脑患儿脑损伤严重程度及临床预后判断有重要参考价值。 相似文献
