Electrical brain stimulation variety of treatments, such as for Parkinson's disease, focal epilepsy and psychosurgery. Sometimes the same electrode is used to probe the brain for finding defective functions, before passing the lesioning current (electrocoagulation). Electrical brain stimulation Electrical brain stimulation (EBS), also referred to as focal brain stimulation (FBS), is a form of electrotherapy and technique used in research and clinical neurobiology to stimulate a neuron or neural network in the brain through the direct or indirect excitation of its cell membrane by using an electric current. It is used for research or for therapeutical purposes. Electrical brain stimulation was first used
Nanoparticles for drug delivery to the brain stabilizing the nanoparticles and preventing the nanoparticles from aggregation. Metallic nanoparticles typically cross the BBB via transcytosis. Nanoparticle delivery through the BBB can be increased by introducing peptide conjugates to improve permeability to the central nervous system. For instance, recent studies have shown an improvement in gold nanoparticle delivery efficiency by conjugating a peptide that binds to the transferrin receptors expressed in brain endothelial cells. Also, solid lipid nanoparticles (SLNs) are lipid nanoparticles with a solid interior as shown in the diagram on the right. SLNs can be made by replacing the liquid lipid oil used in the emulsion process
