It has been well established that the cerebellum and its associated circuitry constitute the essential neuronal system for both delay and trace classical eyeblink conditioning (DEC and TEC). However, whether the cerebellum is sufficient to independently modulate the DEC, and TEC with a shorter trace interval remained controversial. Here, we used direct optogenetic stimulation of mossy fibers in the middle cerebellar peduncle (MCP) as a conditioned stimulus (CS) replacement for the peripheral CS (eg, a tone CS or a light CS) paired with a periorbital shock unconditioned stimulus (US) to examine the ability of the cerebellum to learn the DEC and the TEC with various trace intervals.

Over the past several years, the performance of optoelectronic devices has been improved greatly via the SP enhancement effect. In our previous work, the responsivity of GaN ultraviolet detectors was increased by over 30 times when using Ag nanoparticles.

Three-dimensional (3D) structures with high specific surface areas would improve device performance. Herein, we present a novel procedure to fabricate macroscopic, high-quality, nitrogen-doped, 3D graphene/nanoparticle aerogels.

We aim to compare the efficacy and safety of intensive-dose and standard-dose statin treatment for preventing stroke in high-risk patients.
Methods: A thorough search was performed of multiple databases for publications from 1990 to June 2015.
Objective: To observe the migration and differentiation of the neural precursor cells (NPCs) that derived from murine embryonic stem cells (ESCs) when they were transplanted into amyloid beta (A beta)-treated rat hippocampus.
Methods: MESPU35, a murine ESC cell line that express the enhanced green fluorescent protein (EGFP), was induced differentiation into nestin-positive NPCs by modified serum-free methods. The A beta plaques and the differentiation of the grafted cells were observed by immunofluorescent staining.
Objective To identify the genetype of the PS1/APP double transgenic mouse model, then to analyse the histopathological changes in the brain and compare the differences between the transgenic mice models and Abeta1-40-injected rats models of Alzheimer disease. Methods The modified congo red staining, Nissl's staining and immunohistology staimouse extensively displayed Abeta deposits, activation of astrocyte respectively. Results (1) The PS1/APP transgenic mouse extensively displayed Abeta deposits in the cortex and hippocampal structures, and GFAP positive cells were aggregated in mass and surrounded the congo red-positive plaque.
