Image by Ravi Kiran Kasula.Īre you mesmerised? This image is a simple stylised model showing the layout of the visual cortex of the brain. The Meunier lab looks at some of the smallest parts of the body - proteins a single molecule level - to track molecular processes of nerve cells and how they transmit messages. This stunning image is a snapshot of a live tracking of the Munc18-1 loop mutant protein, which has been implicated in causes infant epilepsy and other neurodegenerative diseases. Research from the Srinivasan Lab shows that budgies fly through openings wider than their wingspan without changing their wing position, but they close their wings when the opening is narrower (left). Birds are ‘body aware’, and can fly through dense foliage with acute precision. This image shows the flight direction and wing patterns of the common budgie, when flying through a gap. Cortical (brain) neurons here are stained and magnified 20x. Two neurons interlace, forming connections and providing mutual support for growth in this beautiful, ethereal image. Cells from each side of the brain must travel a long way across the complex midline environment to make connections. This swirling vortex-like image is a representation of the struggle brain cells endure. The occasional neuron (aqua) has also escaped the black centre of the sphere. Glial cells (orange) and cell nuclei (purple) have migrated from the centre of the sphere. Single-plane image of a neurosphere, a ball of cells grown from a single stem cell. Image by Hanne Thoen from the Marshall lab, which researches the neuroscience of vision. While humans see in 3 channels, mantis shrimp use at least 12, including UV and polarised light! They have the most-known complex visual system of any animal in the world. Image by Ben Sivyer.Īren't neurons beautiful! Cells in the first optic lobe (lamina) of mantis shrimps relay the information to the second (medulla) optic lobe. A recent study by Prof Williams showed that dendrites are not just passive structures for relaying signals, but are integral in processing information about moving light. This tri-layered projection of a ganglion cell in the retina of the eye shows each of the neuron branches (dendrites) colour-coded according of their depth in the retina. Image by Dr Iris Wang in the Anggono lab, who is exploring neural plasticity and how receptors for glutamate are controlled in communication between neurons. Image by Veronkia Halasz, former student in the Cunnington lab, which studies how the brain processes attention and predicting actions.Īxons (the cable of a neuron) from the hippocampus are finely separated (shown as the blue tracks) and labelled with colourful toxins (shown in green and red). Here are scans of 15 brains from university students showing the similarities and differences in shape and folds. Our brains are amazing machines - and have quite an amount of variation between people. Neuron membranes are in red, and active presynaptic boutons and the cell nuclei in green. This is a histological section through the hippocampus with the cell bodies stained in blue. elegans innervate the entire worm's body, so when they are visualised with fluorescent proteins they show the profile of the animal, which have conveniently spelled out QBI! Image by Nick Valmas. This simple system makes studying neurons much easier. This worm is barely 1mm as an adult and has exactly 302 neurons. To do that, we often look to the simple roundworm ( C. Part of QBI's core mission is to understand the fundamental processes of the brain. Image by Andreas Papadopulos, Meunier lab The acto-myosin II rings visible in the bottom left of the cell form to help recovering secretory vesicles that have fused with the plasma membrane. In response, the cortical actin network undergoes remodelling. The image was taken six minutes after stimulation with Ba 2+, which causes secretion. The image displays a 3D reconstruction of the basal cortical actin network. The actin cytoskeleton in neurosecretory cells undergoes a dramatic transformation after stimulation. The neuron shown here has been incubated with a protein, shown in pink, that binds to these synaptic regions. Image by Iris WangĪs neurons grow in culture they develop extensive networks and make connections with one another. Here are just a few of them.įind more images on our Instagram page axons: this image comes from the hippocampus, a region of the brain important for learning and memory. QBI researchers produce beautiful images in the process of studying the brain.
