Front-end and Back-end Computational Modeling of 40-Hz Auditory Steady-State Response Abnormalities in Schizophrenia
Wenjun Xia, Yan Xu, Zhengdi Zhang
40-Hz ASSR is reduced in schizophrenia, but it is unclear if this reflects altered auditory input or cortical E/I dynamics. We hypothesized that similar group differences could ari…
Real-time fall detection based on vision for low-power edge platforms
Wenjun Xia, Zhicheng Peng, Haopeng Li +1
Falling detection is vital for elderly care and intelligent surveillance; however, prevailing vision-based approaches predominantly frame it as static pose classification or discre…
Single-Node Wilson--Cowan Model Accounts for Speech-Evoked -Band Deficits in Schizophrenia
Zhengdi Zhang, Yan Xu, Wenjun Xia
Cortical gamma ()-band activity reflects local excitation-inhibition (E/I) balance. In schizophrenia (SCZ), reduced task-evoked gamma suggests altered E/I dynamics, but it is un…
Audio Outperforms Text for Visual Decoding
Zhengdi Zhang, Hao Zhang, Wenjun Xia
Decoding visual semantic representations from human brain activity is a significant challenge. While recent zero-shot decoding approaches have improved performance by leveraging al…
Classification Accuracy of Minimal Spiking Neural Networks Follows a Log-Reciprocal Function
Zhengdi Zhang, Cong Han, Wenjun Xia
We investigate classification accuracy in minimal LIF-based spiking neural networks, examining its dependence on neuron count, stimulus nodes, and category number. Using an LLM to…
