Channel Makover Switches Off Neurons in a Flash

Frame from the video Channel Makover Switches Off Neurons in a Flash.

Scientists have bioengineered an enhancement to a cutting edge technology that provides instant control over brain circuit activity with a flash of light. The research adds the same level of control over switching neurons off that, until now, had been limited to switching them on. What had been working through a weak pump now works through a highly responsive channel -- like going from a squirt to a gushing hose. Project officer Michelle Freund, Ph.D., of the NIMH Office of Technology Development and Coordination, explains the significance of the new findings.

3-D Analysis of Intact Mouse Hippocampus CLARITY

Frame from the video 3-D Analysis of Intact Mouse Hippocampus CLARITY.

CLARITY provided this 3D view showing a thick slice of a mouse brain’s memory hub, or hippocampus. It reveals a few different types of cells: projecting neurons (green), connecting interneurons (red), and layers of support cells, or glia (blue). Conventional 2D methods require that brain tissue be thinly sliced, sacrificing the ability to analyze such intact components in relation to each other. CLARITY permits such typing of molecular and cellular components to be performed repeatedly in the same brain. Source: Kwanghun Chung, Ph.D., and Karl Deisseroth, M.D., Ph.D., Stanford University.
