A neuron that tracks landmarks helps rats know where they are

Visual landmarks enable an animal to know where it is oriented in relation to its environment. Researchers have identified a new type of neuron in the rat brain, which appears to help facilitate this type of visual and spatial processing.

New imaging method reveals causes of cerebral oedema

Cerebral oedema is a dangerous complication in many brain-related conditions such as strokes. Researchers have now developed a new measurement method that enables a better understanding of the cellular causes of cerebral oedema. According to a new stud…

‘Traveling’ nature of brain waves may help working memory work

The act of holding information in mind is accompanied by coordination of rotating brain waves in the prefrontal cortex, a phenomenon which might confer specific advantages, a new study suggests.

Researchers discover new way to target secondary breast cancer that has spread to the brain

A study has revealed a potential new way to treat secondary breast cancer that has spread to the brain, using existing drugs.

Why the human brain is more vulnerable to disease

With the help of cerebral organoids, scientists were able to ascertain that tuberous sclerosis, a rare neurodevelopmental genetic disorder, arises developmentally rather than only genetically. With these patient-derived laboratory models of the human b…

Another pandemic challenge for nurses: Sleep problems

More than half of nurses had difficulty sleeping during the first six months of the COVID-19 pandemic — and getting less sleep increased their odds of experiencing anxiety and depression, according to a new study.

Research reveals new links between brain over-activity and schizophrenia symptoms

New research has shown that over-activity in a specific area of the brain is linked to certain symptoms of Schizophrenia, opening up possibilities for the development of more targeted treatments.

Chemotherapy’s effectiveness may vary with time of day

New research suggests that chemotherapy could better target brain tumors in mouse models when it was administered at night instead of during the day. That’s because the blood-brain barrier was more likely to allow the chemotherapy to pass through it at…

A virtual reality ‘Shopping Task’ could help test for cognitive decline in adults

New research suggests that a virtual reality test in which participants ‘go to the shops’ could offer a potentially promising way of effectively assessing functional cognition, the thinking and processing skills needed to accomplish complex everyday ac…

Study detects how a genetic variant modifies the brain stimulation impact on memory

The gene of the brain-derived neurotrophic factor (BDNF) is associated with several processes related to memory and brain plasticity. Now, a new article reveals that it is easier to alter the cognitive activity through transcranial magnetic stimulation…
