How injured nerves stop themselves from healing

Researchers found that a protein called CXCL12 attracts growing nerve fibers and keeps them entrapped at the injury site. This prevents regeneration in the central nervous system. Eliminating the receptor for CXCL12 improved axonal regeneration, offering a potential starting point for new drugs.

From individual receptors towards whole-brain function

A research team created a computer model that can simulate the impact of individual receptor types on brain activity. The model uses data from three imaging techniques to quantify receptor-specific modulations of brain states. By predicting changes in brain dynamics after receptor activation, the researchers hope to develop new diagnos...

Willpower is the key to enhancing learning and memory: researchers uncover the mechanism

A study published in PNAS found that theta oscillations in the human brain, generated by the hippocampus, play a crucial role in active learning and memory formation. Active navigation improves learning efficiency, while two consecutive phenomena, encoding and retrieval, are facilitated by theta phase code.
