From the infrastructural and geographical to the viral and the genetic, Echoes of Perfusion is a trans-scalar meditation on the notion of path: described in mathematics as a sequence of links that begins at a node or vertex and then travels from vertex to vertex.

A medical term, perfusion refers to the movement of fluid through the circulatory or lymphatic system to an organ or tissue. Measured as the rate at which blood is delivered to tissue, the concept and term are often used in the healthcare industry to reference curative methods of fluid supply to the body. But perfusion is also a means for viral and microbial transmission—the circulation of certain bacterial, viral, and cancerous cells allows them to covertly migrate and eventually conquer much larger parts of the body.

When these notions of intelligent circulation and supply are scaled to capitalist and geopolitical systems of domination, the economy of the body can be seen as a microcosm of the diffusion of neocolonial power and a model for the feedback loop of structural domination. Motorways, liquid flows, sound waves, nerve fibers... in every dimension imaginable, info-power travels through omnifarious pathways—the passage shaping the info-power and vice versa.

In a stream of consciousness, Zhang explores various contradictions between these abstract and material considerations. The path takes on a biomathematic and aesthetic function here. Straddling the sublime and bio-systemically grievous, it transports the viewer through physiological pathways and concrete overpasses. No matter the host/vessel/infrastructure, each sensory experience gives rise to an uncanny experience of déjà vu: a moving-through strangely un/familiar to the body and the mind.

灌流的回声

从基础设施到地理学，从病毒到基因，《灌流的回声》是一次对“路径”概念的跨尺度沉思：在数学中，路径被描述为从一个节点（node）或端点（vertex）开始，然后从端点到端点的一系列链接。

作为医学术语，灌流是指液体通过循环或淋巴系统向器官或组织的运动。 用血液输送到组织的速度来衡量，这个概念和术语在医疗行业中经常被用来指代治疗性的体液供应。 但灌流也是病毒和微生物传播的一种手段——某些细菌、病毒和癌细胞的循环使它们能够隐蔽地迁移并最终征服更大的身体部位。

当这些智能循环和供应的概念被放大到资本主义和地缘政治的统治体系中时，身体的经济学可以被看作新殖民主义权力扩散的缩影，以及结构性统治的反馈循环模型。车道、液体流、声波、神经纤维...........在每一个可以想象到的维度，信息力（info-power）都会通过各式各样的路径来传播，而路径又会对信息力进行塑形，反之亦然。

张文心以意识流的方式探讨了上述抽象性和物质性要素之间的矛盾。在这里，路径兼具了生物数学和美学的功能，它横跨崇高感和生物系统性的悲哀，将观看者同时引导至体内的通道中和混凝土立交桥上。不管是经由何种主体/躯壳/基础设施，每一次的观看都召唤着一次似曾相识（déjà vu）的微妙感官体验：一种对身体和心灵的即熟悉又陌生的穿越。
