A self-powered deep brain stimulation has been demonstrated by a flexible piezoelectric PIMNT energy harvester to induce behavioural changes in a mouse.

Sensations from viscera, like fullness, easily become painful if the stimulus persists. Mice lacking alpha1G T-type Ca2+ channels show hyperalgesia to visceral pain. Thalamic infusion of a T-type blocker induced similar hyperalgesia in wild-type mice. In response to visceral pain, the ventroposterolateral thalamic neurons evokeda surge of single spikes, which then slowly decayed as T type-dependent burst spikes gradually increased. In alpha1G-deficient neurons, the single-spike response persiste

This study investigates pricing and return policies under various supply contracts in a closed-loop supply chain in which a supplier has more bargaining power than a retailer. We develop integrated supply contract models based on the principal–agent paradigm. Specifically, the supplier with more bargaining power devises a supply contract, acting as a Stackelberg leader. Then, given the contract offer, the retailer decides on pricing and return policies which affect consumers’ demand and return b

Spatiotemporal mapping of neural interactions through electrocorticography (ECoG) is the key to understanding brain functions and disorders. For the entire brain cortical areas, this approach has been challenging, especially in freely moving states, owing to the need for extensive craniotomy. Here, we introduce a flexible microelectrode array system, termed iWEBS, which can be inserted through a small cranial slit and stably wrap onto the curved cortical surface. Using iWEBS, we measured dynamic
