Short-term plasticity of the motor cortex compensates for bradykinesia in Parkinson’s disease
Neurobiology of Disease, 2023 Patients with Parkinson's disease (PD) show impaired short-term potentiation (STP) mechanisms in the primary motor cortex (M1). However, the role played by this neurophysiological abnormality in bradykinesia pathophysiology is unknown.

Preparation of Dispersion-Strengthened Coppers with NbC and TaC by Mechanical Alloying
Materials Transactions, JIM, 1991 To prepare a dispersion-strengthened copper-based alloy, mechanical alloying was carried out using pure copper, niobium, tantalum and graphite powders. After mechanical alloying for 144.0 ks,a Cu-Nb-C solid solution+NbC mixture powder and a Cu-Ta-C solid solution+Ta+TaC mixture powder were obtained inthe Cu-Nb-C and Cu-Ta-C systems, respectively. These
