Insight into the proteins in the brain that detect cannabis

Researchers have made new progress in understanding how cannabinoid receptors (CB1Rs), the proteins that detect the active components of marijuana, are controlled in the brain.

Glial cells may play key epilepsy role

Neuroscientists present a new, detailed accounting of how a mutation in a fly model of epilepsy undermines the ability of glial cells to regulate the balance of ions that neurons need to avoid producing seizures.

Can ‘forest bathing’ reduce stress levels?

A recent review and meta-analysis sets out to uncover whether simply spending time in a forest can measurably reduce stress levels.

Brain area tied to emotions is larger in vets, service members with mild TBI and PTSD

A new study finds that veterans and active-duty service members with combat-related PTSD and mild traumatic brain injury had larger amygdalas — the region of the brain that processes such emotions as fear, anxiety, and aggression — than those with on…

Mindfulness may help decrease stress in caregivers of veterans

Caregivers of veterans who engaged in mindfulness-based cognitive therapy found it relieved stress, anxiety and worry, according to a new study.

Widespread brain connections enable face recognition

Remembering a familiar face engages a wider network of brain regions than previously thought, according to a new study.

How the olfactory brain affects memory

How sensory perception in the brain affects learning and memory processes is far from fully understood. Neuroscientists have discovered a new aspect of how the processing of odors impacts memory centers. They showed that the piriform cortex — a part o…

Why does insomnia worsen distress of unpleasant memories?

Brain activity differences may help explain why distress from bad memories grows stronger in people with insomnia but fades in those without insomnia.

New view on the mechanisms of how the brain works

After a series of studies, researchers have shown that not only one part, but most parts of the brain can be involved in processing the signals that arise from touch. The results open the way for a new approach to how the brain’s network of neurons pro…

What makes memories stronger?

Scientists have found that highly demanding and rewarding experiences result in stronger memories. By studying navigation in rats, the researchers traced back the mechanism behind this selective memory enhancement to so-called replay processes in the h…
