Author: Jose V. Torres-Perez (@Jovitope) is a Postdoctoral Researcher at the School of Biological and Chemical Sciencies, Queen Mary, University of London (UK). This is the story of primary cilium, a cellular structure discovered at least 122 years ago. It was soon regarded as rudimentary and then forgotten for most researchers. Nonetheless, recent advances proved […]

By Francisco R. Villatoro

Human brain has about 85 billion neurons. Each neuron forms thousands of chemical and electrical synapses with other neurons. To record the synaptic activity of each neuron in the brain an intracellular probe with a millivolt scale is required. Glass electrodes are widely used, but they are fragile and they have high impedance. An intracellular […]
