Article Synopsis
  • Skeleton-based human interaction recognition is complex due to challenges in effectively utilizing various skeletal modalities and constraints in capturing two-person interactions.
  • The new multi-modal enhancement transformer (ME-Former) network addresses these issues by incorporating a multi-modal enhancement module and a context progressive fusion block to improve feature extraction and interaction modeling.
  • Experimental results on the NTU-RGB+D datasets show that ME-Former significantly outperforms existing GCN-based methods, proving its effectiveness in recognizing human interactions.

The development of two-photon microscopy and Ca indicators has enabled the recording of multiscale neuronal activities and thus advanced the understanding of brain functions. However, it is challenging to perform automatic, accurate, and generalized neuron segmentation when processing a large amount of imaging data. Here, we propose a novel deep-learning-based neural network, termed as NeuroSeg-II, to conduct automatic neuron segmentation for two-photon Ca imaging data.

Quantitative and mechanistic understanding of learning and long-term memory at the level of single neurons in living brains require highly demanding techniques. A specific need is to precisely label one cell whose firing output property is pinpointed amidst a functionally characterized large population of neurons through the learning process and then investigate the distribution and properties of dendritic inputs. Here, we disseminate an integrated method of daily two-photon neuronal population Ca imaging through an auditory associative learning course, followed by targeted single-cell loose-patch recording and electroporation of plasmid for enhanced chronic Ca imaging of dendritic spines in the targeted cell.
