A Direct Link From The Brain’s Emotion Areas To The Motor Cortex

In high stress situations like making a goal in soccer, some athletes go through a quick slump in performance under pressure, known as “choking.” Now, Salk Institute researchers have uncovered what might be behind the phenomenon – one-way signals from the brain’s emotion circuit to the movement circuit. The research[1] could lead to new strategies […]

Does Brain’s Decision-making Structure Operate Hierarchically?

The striatum, a vital area of the brain involved with decision making, appears to operate hierarchically, similar to a large corporation with executives, middle managers and employees, according to researchers at the Okinawa Institute of Science and Technology (OIST) Graduate University in Japan. The striatum is part of the basal ganglia, the inner core of […]

What is the Substantia Nigra?

The substantia nigra is a brain structure located in the midbrain that plays an important role in reward, addiction, and movement. Substantia nigra is Latin for “black substance”, reflecting the fact that parts of the substantia nigra appear darker than neighboring areas due to high levels of neuromelanin in dopaminergic neurons. It was discovered in […]
