Smartphones Can Predict Brain Function Associated With Anxiety and Depression

Data collected from smartphones can accurately predict connectivity between brain regions associated with emotional processing. Analyzing cellphone data, such as social activity, screen time, and location, alongside fMRI brain scans, researchers found smartphone data activity mirrors brain activity associated with depression and anxiety.

To Perceive Faces, Your Brain Relies on a Process Similar to Computer Face Recognition Systems

Some patients with a disorder called hemi-PMO see distortions in the same half of a person's face, regardless of the angle they view the face. Findings suggest the visual system standardizes all the faces we perceive using the same process, so they can be better compared to faces we have seen before. Read More

Your brain shows if you are lonely or not

In the medial prefrontal cortex, loneliness is associated with a reduced representational similarity between the self and others. Feeling socially disconnected may be mirrored by a self-representation of being a "loner." Read More

Our visual world of color is largely incorrect

People are oblivious to change when color is removed from peripheral vision. Research reports the brain likely fills in for much of our perceptual experience when it comes to seeing the entire picture in color. Read More

How the brain forms habits

As the brain starts to develop new habits, activity in the dorsolateral striatum increases. As the activity bursts increase, the habit becomes stronger. Inhibiting neural activity with optogenetics reduces habit behaviors in mice. Read More

Autism can be measured through a non-verbal marker

A visual test may be a new tool in the diagnosis of autism. Individuals on the autism spectrum are slower to dampen neural activity in response to visual stimuli in the brain. Using EEG data collected from the visual region, researchers could predict with 87% accuracy whether or not a person had ASD. Read More

Study Explains Public Resistance to Vaccinations

Study reports past problems with vaccine research can cause hysteresis, or a negative history that stiffens the resolve of some against vaccinations. The findings shed light on why it is hard to improve vaccine uptake, even when there is overwhelming evidence of the safety and benefits of vaccinations. Read More

Brain Learns to Recognize Familiar Faces Regardless of Where They Are in Visual Field

Researchers report facial recognition varies by where they appear in the visual field, and this variability is reduces through learning familiar faces via social interactions. The study reports repeated social interactions tune visual neurons in the face processing network to enable consistent and rapid rapid recognition of familiar faces. Read More
