When a neuron ages, it loses synaptic connections with other neurons, it is less able to transmit nerve impulses, and its metabolism is also altered. This process of neuronal aging—inevitable with the ...
The human brain contains billions of neurons, specialized nerve cells that communicate with each other via electrical and ...
Schematic representation of axonal transport vesicles (blue) carrying presynaptic proteins (SV and AZ proteins). Kinesin motor proteins (KIF1A) attach these vesicles and carry them along the axons to ...

Scientists mapped every neural link in an adult fruit fly’s brain for the first time
Researchers have produced the first complete wiring diagram of an adult fruit fly brain, tracing roughly 139,255 neurons and ...
Summary: Researchers compiled emerging evidence to prove that astrocytes, traditionally dismissed as passive, structural ...
Our brain is a complex organ. Billions of nerve cells are wired in an intricate network, constantly processing signals, enabling us to recall memories or to move our bodies. Making sense of this ...
Insights from advanced imaging technology show how neurons communicate at the atomic level for the first time. For the first time, scientists at The Hospital for Sick Children (SickKids) used advanced ...
A regulatory protein in astrocytes may explain how certain memories persist over time for learning and cognitive function.
Summary: Astrocytes, star-shaped non-neuronal cells, serve as active gatekeepers of long-term memory stability. By ...
