New doors open to the understanding of the origin of brain tumours

Normally, adult brain stem cells form more mature cells such as nerve cells (neurones) astrocytes (supporting cells) or oligodendrocytes (myelin forming cells that wrap around processes of neurones). Researchers at the Division of Neuropathology at UCL Institute of Neurology have shown that different mutations in the stem cells turn them into different types of brain cancer.

Queen Square scientists question memory theory

Neuroscientists formed this theory based on observation of patients with amnesia, a condition that severely disrupts the ability to form long-lasting memories. Typically, amnesia is caused by injury to the hippocampi, a pair of brain structures located in the depth of the temporal lobes. More...

Dopamine enhances expectation of pleasure in humans
