Dopamine signals when a fear can be forgotten

A new study shows how a dopamine circuit between two brain regions enables mice to extinguish fear after a peril has passed.

New non-invasive brain stimulation technique shows significant reduction in depression, anxiety and PTSD symptoms

New research shows non-invasive sound wave therapy can directly target deep brain regions, significantly reducing depression, anxiety, and PTSD symptoms.

Brain decoder controls spinal cord stimulation

A lab develops brain wave decoder that may help in spinal cord injury rehabilitation.

In Down syndrome mice, 40Hz light and sound improve cognition, neurogenesis, connectivity

A new study provides new evidence that sensory stimulation of a gamma-frequency brain rhythm may promote broad-based restorative neurological health response.

Immune cells drive congenital paralysis disease

Patients with spastic paraplegia type 15 develop movement disorders during adolescence that may ultimately require the use of a wheelchair. In the early stages of this rare hereditary disease the brain appears to play a major role by over-activating th…

Compelling new insights into dynamics of the brain’s serotonin system

A new study sheds new light on these big questions, illuminating a general principle of neural processing in a mysterious region of the midbrain that is the very origin of our central serotonin (5-HT) system, a key part of the nervous system involved i…

Awkward. Humans are still better than AI at reading the room

Humans are better than current AI models at interpreting social interactions and understanding social dynamics in moving scenes. Researchers believe this is because AI neural networks were inspired by the infrastructure of the part of the brain that pr…

Even light exercise could help slow cognitive decline in people at risk of Alzheimer’s

In a landmark clinical trial people at risk for Alzheimer’s who exercised at low or moderate-high intensity showed less cognitive decline when compared to those receiving usual care.

Exercise boosts brain health — even when energy is low

We know exercise is good for our body, but what about our brains? A new study suggests that exercise plays a crucial role in keeping our minds sharp, even when one of the brain’s key energy sources isn’t available. The study offers fresh insight into b…

What happens in the brain when your mind blanks

Mind blanking is a common experience with a wide variety of definitions ranging from feeling ‘drowsy’ to ‘a complete absence of conscious awareness.’ Neuroscientists and philosophers compile what we know about mind blanking, including insights from the…
