Special Issue Information

Dear Colleagues,

Brain-inspired intelligence uses the principles of brain science to build algorithms and computational intelligent systems with human-like intelligence. Scientists are focused on the studies of brain-inspired computer chips for highly sophisticated neural models involving neuronal units and synaptic connections. These can be efficiently applied in not only real-time computational intelligence for large-scale neural circuits but also perceived intelligence with deep learning networks that are approaching state-of-the-art classification accuracy on several vision, speech, and tactility tasks. Engineering the brain by mimicking the structure and function of a neural network on a silicon integrated circuit is the goal of embedded computational intelligence. ARM and FPGA processors are the main flexible components in the embedded system design and achieve their reliability through hardware and software technology, which can provide a high-speed, real-time, and low-power embedded platform for brain-inspired computation that boosts the applications of neural computation in both the industrial and medical fields.

This Special Issue focuses on recent advances in modeling and embedded applications in brain-inspired computation, which might be used for different purposes such as simulation of neural circuits, neural control engineering, synaptic learning rules, perceived tasks in edge computing, etc. Reviews of state-of-the-art brain-inspired artificial intelligence in embedded systems are also welcome.

The topics of interest for this Special Issue include the following: 

  1. Biophysical-based neuromorphic modeling from single neuron to large-scale neural network.
  2. Hardware acceleration strategies of neural circuit simulation on embedded systems.
  3. Closed-loop neuromodulation for neurological diseases such as epilepsy, Parkinson’s disease, depression, etc.
  4. Hardware in-loop simulations for invasive or noninvasive brain stimulation technologies such as DBS, TMS, tDCS, tACS, etc.
  5. Embedded implementation of deep neural networks, including CNN, SNN, RNN, etc.
  6. Lightweight deep learning network for embedded platforms.
  7. Perceived intelligence (vision, speech, tactile, etc.) applications in edge computing.
  8. Communication architectures involved in multi-core embedded systems.
  9. Synaptic learning rules in deep neural networks.

It should be pointed out that the topics are not limited to the above list and we will consider submission in any area of the application of brain-inspired artificial intelligence.

Embedded systems are the best solution to achieve high-performance edge terminal computing tasks. With the rapid increase in the amount of data generated by edge devices, it is imperative to implement intelligent algorithms with large amounts of data and computation on embedded terminal systems. In this paper, a novel multi-core ARM-based embedded hardware platform with a three-dimensional mesh structure was first established to support the decentralized algorithms. To deploy deep convolutional neural networks (CNNs) in this embedded parallel environment, a distributed mapping mechanism was proposed to efficiently decentralize computation tasks in the form of a multi-branch assembly line. In addition, a dimensionality reduction initialization method was also utilized to successfully resolve the conflict between the storage requirement of computation tasks and the limited physical memories. LeNet-5 networks with different sizes were optimized and implemented in the embedded platform to verify the performance of our proposed strategies. The results showed that memory usage can be controlled within the usable range through dimensionality reduction. The down-sampling layer as the base point of the mapping for the inter-layer segmentation achieved the optimal operation in lateral dispersion with a reduction of around 10% in the running time compared with the other layers. Further, the computing speed for a network with an input size of 105 × 105 in the multi-core parallel environment is nearly 20 times faster than that in a single-core system. This paper provided a feasible strategy for edge deployments of artificial intelligent algorithms on multi-core embedded devices. Full article

Both robustness and self-repairing of the rhythmic behaviors generated by central pattern generators (CPGs) play significant roles in locomotion control. Although current CPG models have been established to mimic rhythmic outputs, the mechanisms by which the self-repairing capacities of CPG systems are formed are largely unknown. In this paper, a novel bio-inspired self-repairing CPG model (BiSRP-CPG) is proposed based on the tripartite synapse, which reveals the critical role of astrocytes in the dynamic coordination of CPGs. BiSRP-CPG is implemented on the parallel FPGA platform to simulate CPG systems on real physiological scale, in which a hardware implementation method without multiplier is utilized to break the limitation of FPGA hardware resources. The experimental results verified both the robustness and self-repairing capabilities of rhythm of BiSRP-CPG in the presence of stochastic synaptic inputs and “faulty” synapse. Under the synaptic failure rate of 20%, BiSRP-CPG suffered only 10.53% performance degradation, which was much lower than the 36.84% spike loss rate of CPG networks without astrocytes. This paper provides an insight into one of the possible self-repair mechanisms of brain rhythms which can be utilized to develop autonomously fault-tolerant electronic systems. Full article

With the rapid development of advanced neuroimaging techniques, understanding the brain in terms of structural and functional connectomes has become one of the frontier topics in neuroscience. Different from traditional descriptive brain network models, which focused on single neuroimaging modal and temporal scales, multiscale brain network models consisting of mesoscopic neuronal activity and macroscopic functional dynamics can provide a mechanistic understanding for brain disorders. Here, we review the foundation of multiscale brain network models and their applications in neuropsychiatric diseases. We first describe some basic elements of a multiscale brain network model, including network connections, dynamics of regional neuronal populations, and model fittings to different metrics of fMRI. Secondly, we draw comparisons between multiscale brain network models and other large-scale brain models. Additionally, then we survey the related applications of multiscale brain network models in understanding underlying mechanisms of some brain disorders, such as Parkinson’s disease, Alzheimer’s disease, and Schizophrenia. Finally, we discuss the limitations of current multiscale brain network models and future potential directions for model development. We argue that multiscale brain network models are more comprehensive than traditional single modal brain networks and would be a powerful tool to explore neuronal mechanisms underlying different brain disorders measured by neuroimaging.
