A recent study published in Nature Communications reveals that the mechanical properties of the developing brain play a significant role in synapse formation and electrical signal emergence. The researchers found that softer regions exhibit higher synapse densities, while stiffer regions show lower densities.
A team of researchers has established the first comprehensive model of how calcium is transported out of the cell by the plasma membrane Ca²⁺-ATPase, explaining its high speed. The model reveals that PIP₂ stabilizes calcium binding and facilitates rapid release, making it the pump's primary acceleration factor.
Researchers at ISTA investigated the crucial set of synapses between neurons within the cerebellum, uncovering details of their function and development. The study used advanced techniques to look at the inhibitory synapses in great detail, revealing how they delicately influence the cell's signal output.
Researchers developed a tapered fiber optoacoustic emitter (TFOE) for non-genetic photoacoustic neural stimulation at the single cell level. The technology achieves high spatial resolution and optoacoustic conversion efficiency, allowing for precise control over neuron activity patterns.
Electrical engineers at ETH Zurich and biologists from the University of Bern have developed a new method to record the activity of moving cells, including beating cardiac muscle cells. The new method combines the patch-clamp technique with an atomic force microscope, allowing for longer measurements and automation.
Researchers at CSHL used a new technique to measure neural responses in awake rats, finding that only 5% of neurons react strongly to specific sounds. This discovery may help explain how we focus on one sound amidst noise and could inform ways to improve sound learning.
A team of scientists has discovered that a protein called CatSper1 plays a crucial role in hyperactivation, the whiplike motion of sperm tails, and male fertility. The breakthrough uses patch clamp recording to study electrical currents inside sperm cells, opening new avenues for research into infertility and contraception.
