Diffusion MRI Ch1: Introduction to Diffusion Magnetic Resonance

Source A. What is diffusion Diffusion is a mass transport process arising in nature. It results in molecular or particle mixing without requiring bulk motion. Fick’s laws of diffusion describes the diffusion phenomenon that explain mixing. (Adolf Fick 1855) J= -D∇C J is the net diffusion flux vector D is the diffusion coefficient (intrinsic property … Continue reading

New two-photon calcium microscope records Firing of Thousands of Individual Neurons in 3-D

UCLA neuroscientists have collaborated with physicists to develop a non-invasive, ultra-high-speed microscope that can record in real time the firing of thousands of individual neurons in the brain as they communicate, or miscommunicate, with each other. Simultaneous two-photon calcium imaging at different depths with spatiotemporal multiplexing Adrian Cheng, J Tiago Gonçalves, Peyman Golshani, Katsushi Arisaka … Continue reading
