Neuromodulation in epilepsy is a proven treatment for people with drug-resistant focal epilepsy. Dual device therapies are increasingly utilized in people with drug-resistant epilepsy. Vagus nerve stimulation (VNS) and deep brain stimulation (DBS) target the thalamus involving the primary neurobiological network in patients with genetic generalized epilepsy (GGE). We report a novel case of combined neuromodulation in a patient with drug-resistant GGE who achieved a partial response with seizure reduction after VNS implantation yet following VNS-DBS polyneurostimulation gradually achieved prolonged seizure freedom. We speculate that by combining the indirect activating effects of VNS with the direct inhibitory effects of DBS, this may provide synergy to thalamic modulated networks. We hypothesize a "rational polytherapy" may exist in some patients with GGE undergoing dual neuromodulation.

Alzheimer's disease (AD) is gradually increasing in prevalence and the complexity of its pathogenesis has led to a lengthy process of developing therapeutic drugs with limited success. Faced with this challenge, we proposed using a state-of-the-art drug screening algorithm to identify potential therapeutic compounds for AD from traditional Chinese medicine formulas with strong empirical support. We developed four deep neural network (DNN) models for AD drugs screening at the disease and target levels.

The mammalian brain has an extremely limited ability to regenerate lost neurons and to recover function following ischemic stroke. A biomaterial strategy of slowly-releasing various regeneration-promoting factors to activate endogenous neurogenesis represents a safe and practical neuronal replacement therapy. In this study, basic fibroblast growth factor (bFGF)-Chitosan gel is injected into the stroke cavity.

Parkinson's disease (PD), a degenerative disorder of the central nervous system, is commonly diagnosed using functional medical imaging techniques such as single-photon emission computed tomography (SPECT). In this study, we utilized two SPECT data sets (n = 634 and n = 202) from different hospitals to develop a model capable of accurately predicting PD stages, a multiclass classification task. We used the entire three-dimensional (3D) brain images as input and experimented with various model architectures.

Spatially resolved transcriptomics technologies provide high-throughput measurements of gene expression in a tissue slice, but the sparsity of these data complicates analysis of spatial gene expression patterns. We address this issue by deriving a topographic map of a tissue slice-analogous to a map of elevation in a landscape-using a quantity called the isodepth. Contours of constant isodepths enclose domains with distinct cell type composition, while gradients of the isodepth indicate spatial directions of maximum change in expression.
