Circuits and innate behaviour

In this issue

In recent years, neuroscientists have made great strides in understanding the mechanisms and processes of innate behaviour as well as the circuits (both anatomical and molecular) that mediate them. For instance, a new Nature paper describes a powerful method to uniquely label individual cells within a population, and thereby distinguish adjacent neurons and cellular processes. This genetic labelling of neurons with multiple distinct colours allows for the large-scale analysis of neuronal circuits. Another paper in the same issue uses calcium imaging and genetic techniques to characterize the circuits in Caenorhabditis elegans that control food and odour-evoked behaviour.

This special web focus highlights some of the advances in understanding both the circuits and the mechanisms of innate behaviours (such as sexual behaviour, olfaction, sleep and touch) made in the past year. We also present some of the recent technical breakthroughs that hold great promise for the dissection of such circuits and their functions.

Smell: The worm turns

The worm Caenorhabditis elegans has many advantages as an experimental organism. These have been exploited to investigate how, at a single-neuron level, neural circuits transform sensory signals into behaviour.
