Memory Block: How Saturated Fats May Hinder Memory Formation in the Aging Brain

Memory Block: How Saturated Fats May Hinder Memory Formation in the Aging Brain

A new study suggests that a high-fat diet may impair memory by causing inflammatory effects and issues in cell-signaling management in the brain cells, especially as people age, but the omega-3 fatty acid DHA may help mitigate these effects. The research, focusing on microglia…

Three new projects launched to map neuronal connections in the mouse and macaque brains

Three new projects launched to map neuronal connections in the mouse and macaque brains

A complete map of all the connections in an entire mammalian brain may be in sight. Allen Institute researchers have just launched three new projects to construct large, detailed maps of neuronal connections in sections of the mouse and macaque brains, with an eye…

Living model of brain reveals how human neurons work together to process information

Living model of brain reveals how human neurons work together to process information

“Dishbrain’ under the microscope. A microscopy image of neural cells where fluorescent markers show different types of cells. Green marks neurons and axons, purple marks neurons, red marks dendrites, and blue marks all cells. Where multiple markers are present, colors are merged and typically…

Battle of the Dendrites: How Neurons Compete To Cut Connections

Battle of the Dendrites: How Neurons Compete To Cut Connections

Researchers at Kyushu University discovered the chemical pathways that regulate synaptic pruning, a crucial phase in brain development where excessive and incorrect neuronal connections are eliminated. The team found that in the presence of neurotransmitter signaling, the receiving dendrite is protected while other dendrites…
