Weekly Neuroscience Update

Researchers have developed a new computational model of major depressive disorder. The model reveals older memories, as well as short term memories, are affected by major depressive disorder. Researchers say how long the memory deficits go back depends on how long the depressive episode lasts.

A new brain cancer atlas maps out comprehensive, visually rich information about the anatomical and genetic bases of glioblastoma, researchers report.

A new study reports people who have a family history of alcohol use disorder release more dopamine in the ventral striatum as a response to the expectation of receiving an alcoholic drink than those without a family history of alcoholism.

A drug that blocks the alpha7 nicotinic acetylcholine receptor may provide a new method for combating drug addiction relapse, researchers report.

A groundbreaking study reveals human immune cells in the blood can be transformed into functional neurons within 3 weeks by adding four proteins. The discovery could be used to generate neurons to study specific psychological and neurological disorders, researchers say.

Researchers report transcranial magnetic stimulation predisposes neural connections in the visual cortex for reorganization.

Researchers have created a new model that may help explain how the brain stores memories of tangible events. The new model explains how neural activity in the hippocampus can help map space, time and context in episodic memories.

A new study reveals people respond to stimuli in another person’s peripersonal space as they could their own.

Research has shown that a developing child’s brain structure and function can be adversely affected when the child is raised in an environment lacking adequate education, nutrition and access to health care.

Finally this week, researchers report intuition is the result of information processing in the brain that results in prediction based on previous experience.
