Individual section planes (A), are reconstructed in the z-axis to build a volumized block of image planes that can be digitally navigated in all axes using image analysis software (B).

In addition, we provide critical discussion regarding current experimental limitations and propose future convergent methodologies to advance a deeper understanding of neuroanatomy.Ĭurrent methods for volume EM rely on three-dimensional (3D) image reconstruction from ultrathin serial sections made through intact nervous tissue. Here we briefly trace the evolution of the technological arsenal currently available for probing neuron and circuit architecture.

These new techniques for monitoring and manipulating circuits, neurons, and synapses are providing expanded capability that heralds a new era of functional neuroanatomy.

In addition, endeavors are underway to build high-resolution maps of all the neurons and their full complement of synapses in multiple model organisms 1. Neuroanatomy in the 21 st century is being rekindled by the merger of molecular and genetic manipulations aimed at probing circuit function with gene expression profiling, high-resolution imaging, and electrophysiology. Bridging this conceptual chasm requires knowledge across several scales ranging from cell-type specific genetic identity, population-level network connectivity, the function and dynamics of individual synapses, and circuit output. In most cases, it is far from clear how brain functions emerge from existing circuit diagrams. Our current understanding of how neuronal circuits produce sensory perception, memory, and behavior remains nascent. To fully unravel complex neural computations and representations, we must consider both the structure of connections formed between intermingled cell types, and how electrical activity propagates through the network to enable its dynamic function.

However, understanding how neurons “wire” through synapses, the microcircuits they form, and how those microcircuits participate in neural networks to drive perception and behavior remains one of biology’s major frontiers. Individual neurons represent the elemental building blocks of the brain.
