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

calcium imaging

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

A Wireless Brain-Machine Interface for Real-Time Speech Synthesis

Figure 1. Schematic of the brain-machine interface for real-time synthetic speech production. Black circles and curved arrows represent neurons and axonal projections, respectively, in the neural circuitry for speech motor output. The volunteer’s stroke-induced lesion in the efferent motor pathways (red X) disconnects motor plans represented in the cerebral cortex from the speech motoneurons, thus disabling speech output while sparing somatic, auditory, and visual sensation as well as speech motor planning centers in cerebral cortex. Signals collected from an electrode implanted in the subject’s speech motor cortex are amplified and sent wirelessly across the scalp as FM radio signals. The signals are then routed to an electrophysiology recording system for further amplification, analog-to-digital conversion, and spike sorting. The sorted spikes are sent to a Neural Decoder which translates them into commands for a Speech Synthesizer. Audio signals from the synthesizer are fed back to the subject in real time.

MRI-Visible Micellar Nanomedicine for Targeted Drug Delivery to Lung Cancer Cells

id11014

Polymeric micelles are emerging as a highly integrated nanoplatform for cancer targeting, drug delivery and tumor imaging applications. In this study, we describe a multifunctional micelle (MFM) system that is encoded with a lung cancer-targeting peptide (LCP), and encapsulated with superparamagnetic iron oxide (SPIO) and doxorubicin (Doxo) for MR imaging and therapeutic delivery, respectively. The … Continue reading
