How the brain helps us make good decisions, and bad ones

The orbitofrontal cortex (OFC) appears to play a significant role in our ability to make decisions. A network connecting the OFC and nucleus accumbens translates negative outcomes into values, while the OFC-amygdala circuit helps stabilize action values.

Altered Brain Activity in Antisocial Teenagers

Neuroimaging reveals lower activation in the dorsolateral prefrontal cortex and angular gyrus in teenage girls with conduct disorder. Findings suggest that a reduction in prefrontal brain regions and functional connectivity during effortful emotional regulations contribute to behaviors associated with antisocial behavior in teenage girls.

Proof it’s possible to enhance or suppress memories

Using optogenetics to stimulate different areas of the hippocampus has the ability to enhance or suppress memories in mice. The findings could have implications for suppressing memories associated with traumatic events in PTSD, and also in enhancing cognitive ability or improving memory for those with neurodegenerative diseases, in the future.

The insular cortex processes, and drives learning from pain

Using optogenetics to 'switch off' the insular cortex in mice experiencing a painful event resulted in a less fearful reaction to pain. The ability of the mice to learn avoidance from the pain event was also reduced.

Newly discovered gene mutation reduces fear and anxiety, and increases social interaction

The Ph4-tm gene has been implicated in fear and anxiety. P4h-tm knockout mice showed diminished response to fear and showed more courageous behavior than wild-type mice with a functional P4h-tm gene.
