Thorny life of new-born neurons

The hippocampus is a critical region in the brain for learning and memory. For the first time, scientists have observed how stimulation causes the spines on its neuronal dendrites to enlarge.

Scientists discover schizophrenia gene roles in brain development

A USC research team identified 150 proteins affecting cell activity and brain development that contribute to mental disorders, including schizophrenia, bipolar condition and depression.

Waves move across the human brain to support memory

Engineers have discovered a new fundamental feature of brain oscillations: they actually move rhythmically across the brain, reflecting patterns of neuronal activity that propagate across the cortex. The researchers also found that the traveling waves …

Sleep problems in Parkinson’s disease: Can we fix them?

Researchers have uncovered why people with a hereditary form of Parkinson’s disease suffer from sleep disturbances. The molecular mechanisms uncovered in fruit flies and human stem cells also point to candidate targets for the development of new treatm…

Maps made of nerve cells

Mice move through the virtual world of a video game and provide insight into the mechanisms of memory formation.

Study of sleeping fur seals provides insight into the function of REM sleep

All land mammals and birds have two types of sleep: rapid eye movement (REM) and non-REM (also called slow-wave sleep). Earlier evidence had suggested that REM sleep is essential for physical and mental well-being and learning, but the underlying funct…

Normal eye dominance is not necessary for restoring visual acuity in amblyopia

Research published today may lead to changes in how amblyopia is treated, particularly in adults. The research shows that eye dominance and visual acuity are controlled by different areas of the brain, and that one can be corrected without correcting t…

In building the brain, cell pedigree matters

Research in mice shows that a protein made by the stem cells that give rise to neurons, but not by neurons themselves, is key to brain cells’ ability to migrate during development and assume their proper positions This primordial protein acts by clingi…

Sharing spaces: Your brain considers other people’s personal space as your own

Peripersonal space (PPS) is the area immediately around your body used when interacting with people and objects. Recently, researchers have shown that some neurons in the primate brain respond to an infringement of another individual’s PPS as if their …

Negative vs. positive social media experiences and depressive symptoms

Negative experiences on social media carry more weight than positive interactions when it comes to the likelihood of young adults reporting depressive symptoms, according to a new analysis. The finding may be useful for designing interventions and clin…
