Abstract Practical quantum computing will require error rates well below those achievable with physical qubits. Quantum correction 1,2 offers a path to algorithmically relevant by encoding logical qubits within many qubits, for which increasing the number of enhances protection against errors. However, introducing more also increases sources, so density errors must be sufficiently low performance improve code size. Here we report measurement qubit scaling across several sizes, and...
The fear responses to environmental threats play a fundamental role in survival. Little is known about the neural circuits specifically processing threat-relevant sensory information mammalian brain. We identified parvalbumin-positive (PV(+)) excitatory projection neurons mouse superior colliculus (SC) as key neuronal subtype for detecting looming objects and triggering responses. These neurons, distributed predominantly superficial SC, divergently projected different brain areas, including...
Animals respond to environmental threats, e.g. looming visual stimuli, with innate defensive behaviors such as escape and freezing. The key neural circuits that participate in the generation of dimorphic remain unclear. Here we show behavioral patterns triggered by stimuli are mediated parvalbumin-positive (PV+) projection neurons mouse superior colliculus (SC). Two distinct groups SC PV+ form divergent pathways transmit threat-relevant signals parabigeminal nucleus (PBGN) lateral posterior...
Neuropeptides are key signaling molecules in the endocrine and nervous systems that regulate many critical physiological processes. Understanding functions of neuropeptides vivo requires ability to monitor their dynamics with high specificity, sensitivity, spatiotemporal resolution. However, this has been hindered by lack direct, sensitive, noninvasive tools. We developed a series GRAB (G protein-coupled receptor activation‒based) sensors for detecting somatostatin (SST),...

Abstract Feeding behavior is regulated by both the homeostatic needs of body and hedonic values food. Easy access to palatable energy-dense foods consequent obesity epidemic stress urgent need for a better understanding neural circuits that regulate feeding. Here, we report neurotensin-positive neurons in lateral septum (LS Nts ) play crucial role regulating Silencing LS specifically promotes feeding food, whereas activation suppresses overall project tuberal nucleus (TU) via GABA signaling...
The rapid, stable, and undamaged picking of small-sized spherical fruits are one the key technologies to improve level intelligent robots reduce grading operations. Cherry tomatoes were selected as research object in this work. Picking strategies two-stage “Holding-Rotating” finger-end grasping determined. end-effector was designed separate fruit from stalk based on linear motion constraint part rotating gripper. This work first studied human hand-grasping cherry fingers with sinusoidal...
Liraglutide, a glucagon-like peptide-1 (GLP-1) analog, is approved for obesity treatment, but the specific neuronal sites that contribute to its therapeutic effects remain elusive. Here, we show GLP-1 receptor–positive (GLP-1R–positive) neurons in lateral septum (LSGLP-1R) play critical role mediating anorectic and weight-loss of liraglutide. LSGLP-1R were robustly activated by liraglutide, chemogenetic activation these dramatically suppressed feeding. Targeted knockdown receptors within LS,...
Abstract Appetitive locomotion is essential for animals to approach rewards, such as food and prey. The neuronal circuitry controlling appetitive unclear. In a goal-directed behavior—predatory hunting, we show an excitatory brain circuit from the superior colliculus (SC) substantia nigra pars compacta (SNc) enhance in mice. This tectonigral pathway transmits locomotion-speed signals dopamine neurons triggers release dorsal striatum. Synaptic inactivation of this impairs but not defensive...

We investigated if emotion regulation can be improved through self-regulation training on non-emotional brain regions, as well how to change the networks implicated in this process. During period, participants were instructed up-regulate their right dorsolateral prefrontal cortex (rDLPFC) activity according real-time functional near-infrared spectroscopy (fNIRS) neurofeedback signals, and there was no emotional element. The results showed that significantly increased regulation,...

Metal oxide gas sensors (MOGS), crucial components in monitoring air quality and detecting hazardous gases, are well known for their poisoning effects when exposed to certain molecules, such as hydrogen sulfide. Surprisingly, our research reveals that high-temperature H2S treatment leads an enhancement effect rather than response decay. This study investigates the time-decaying enhancement, being attributed formation of metal sulfide sulfate on oxide's surface, enhancing electronic...
