Vision mixing

The diverse, dynamic and unpredictable nature of the real world poses challenges for image sensors. In this week’s issue, Luping Shi and colleagues present a vision chip inspired by the human visual system. Dubbed Tianmouc, the chip parses visual information into primitive representations and then uses two complementary vision pathways — one for cognition-related processing and one for action-related processing — to parse the representations to understand the scene. The cognition processing deals with colour and intensity with high spatial resolution and high precision, while the action processing accounts for spatial and temporal differences with high speed. The researchers successfully tested their chip in an autonomous car, where it achieved robust perception even for challenging issues on the open road.

    • Certain neurons encode memories of events that occurred in specific physical locations known as place fields. Chickadees show patterns of neuronal activity that are specific to locations of hidden food but independent of place fields.

    • Both parents of oldfield mice care for offspring, whereas in deer mice, mothers usually care for pups. The discovery of a type of adrenal-gland cell that is present in oldfield mice but not in deer mice helps to explain the difference.

    • Cement can be reused by including it as a component of steel recycling. This opens the way to an industrial partnership that improves the use of materials and lowers carbon emissions — but only if waste resources are well managed.

    • Artificial neural networks that model the visual system of a male fruit fly can accurately predict the insect’s behaviour in response to seeing a potential mate — paving the way for the building of more complex models of brain circuits.
