New study shows combination therapy slows cognitive decline in at-risk populations

An important new study has demonstrated that a combination therapy can slow cognitive decline in older adults at risk for dementia.

The roots of fear: Understanding the amygdala

Treating anxiety, depression and other disorders may depend on the amygdala, a part of the brain that controls strong emotional reactions, especially fear. But a deep understanding of this structure has been lacking. Now scientists have identified new …

After a heart attack, the heart signals to the brain to increase sleep to promote healing

Study shows how the heart and brain interact to influence sleep patterns and help with recovery.

Healthy brains suppress inappropriate immune responses

Researchers have found a process by which the brain guards against attack by the immune system. In mice with multiple sclerosis, such ‘guardian’ proteins that train the immune system were drastically depleted, and replenishing them improved symptoms, a…

Similarities in brain development between marmosets and humans

In common marmosets, the brain regions that process social interactions develop very slowly, extending until early adulthood, like in humans. During this time, all group members are involved in raising the infants, which contributes to the species’ str…

Combining VR and non-invasive brain stimulation: A neurotechnology that boosts spatial memory without surgery

Researchers have joined forces to give a boost to spatial memory by creating a unique experimental setup that combines non-invasive deep-brain stimulation, virtual reality training, and fMRI imaging. The study demonstrates that targeted, painless elect…

Smell loss linked to 100-plus diseases

Researchers reveal a link between olfactory loss and inflammation in 139 medical conditions. The researchers say loss of smell is an early sign of numerous neurological and bodily diseases.

Magnetic field applied to both sides of brain shows rapid improvement for depression

A type of therapy that involves applying a magnetic field to both sides of the brain has been shown to be effective at rapidly treating depression in patients for whom standard treatments have been ineffective. The treatment — known as repetitive tran…

Discovery of key mechanism in Huntington’s Disease could pave the way for early detection and treatment

Researchers have identified a key biochemical mechanism relevant to the development of Huntington’s Disease. This discovery opens up the possibility of studying the disease before its clinical onset and eventually stopping its progression.

Depression: Dysfunction of neurons in the amygdala may be behind negative perceptions of the environment

One of the characteristics of depression is a tendency to perceive sensory stimuli and everyday situations in an excessively negative way. But the mechanisms underpinning this ‘negativity bias,’ which can fuel the development of depressive symptoms, ha…
