We have developed a whole-cortical electrocorticographic array for the common marmoset that continuously covers almost the entire lateral surface of cortex, from the occipital pole to the temporal and frontal poles. This protocol describes a chronic implantation procedure of the array in the epidural space of the marmoset brain.

Here we present a protocol for Ca²⁺ imaging in neurons and glial cells, which enables the dissection of Ca²⁺ signals at subcellular resolution. This process is applicable to all cell types that allow the expression of genetically encoded Ca²⁺ indicators.

In this protocol, we introduce a method for purifying the dendritic filopodia-rich fraction from the phagocytic cup-like protrusion structure on cultured hippocampal neurons by taking advantage of the specific and strong affinity between a dendritic filopodial adhesion molecule, TLCN, and an extracellular matrix molecule, vitronectin.

Here, we present an alternative protocol to actively induce experimental autoimmune encephalomyelitis in C57BL/6 mice, using the immunogenic epitope myelin oligodendrocyte glycoprotein (MOG)_35-55 suspended in incomplete Freund's adjuvant containing the heat-killed Mycobacterium avium subspecies paratuberculosis.

Here, we describe the modified treatment methods for wasting marmoset syndrome (WMS, also known as inflammatory bowel disease (IBD)-like disease) with tranexamic acid. We also present how to administer the therapeutic agents orally, subcutaneously, and intravenously.
