RESOLVING THE MOLECULAR ARCHITECTURE OF SYNAPSES USING LIGHT MICROSCOPY
Synapses are highly specialized junctions between neurons that are the basis of our understanding of neuronal signal transmission and how memories are formed in the brain. The structure,…
SNIFFING OUT THE ODOR CODE: A ROLE FOR SPIKE TIMING
How would you describe the smell of fresh baked bread, a rose, or an ocean breeze? The world of smell is extremely diverse, and with intangible qualities that…
MOLECULAR MECHANICS OF HEARING AND DEAFNESS
Cadherin-23 stretching simulations. A close-up view of the linker region between cadherin-23 repeats 1 and 2 is shown during a molecular dynamics simulation in which the protein is…
VISUAL SPACE WITHIN A DENDRITE
More than a century ago, famous neuroanatomist and histologist Ramon y Cajal proposed the idea that a neuron receives information through its extensive dendritic tree and sends it…
PERCEIVING SMELLS WITH SPARSE CONNECTIONS
Many regions of the brain are organized in such a way that they form an ordered representation of our sensory experiences. Similar physical stimuli –nearby points of light…
ASTROCYTES SPY ON NEURONAL CONVERSATION TO BRING A RUSH OF BLOOD TO THE HEAD
The human brain represents approximately 2% of the total body weight, but accounts for about 20% of the energy consumed. Functional hyperemia (local increases in blood flow triggered…
DULAC LAB: SMALL RNAS AND THE SENSE OF SMELL
Modern genetics textbooks highlight the concept of the ‘central dogma’ which states that DNA is transcribed into messenger RNA (mRNA) and that mRNA is subsequently translated into proteins. …
MEISTER LAB: THE EYE HAS A SHORT ATTENTION SPAN
No matter how hard we fix our gaze, our eyes are in constant motion due to involuntary head and eye movements. The resulting image motion on our retinas…
FINE-TUNING HEAT SENSITIVITY
This illustration is a surface representation of the TRPV1ankyrin repeat structure (in green) with a bound ATP molecule (multicolor sticks) on a background of capsaicin-laden red pepper flakes.…
