The study used a brain-computer interface to train animals and showed that subjects learned easier-to-learn patterns more readily, while harder-to-learn patterns were entirely new.
A new study reveals that neurons in the brain's inferotemporal cortex fire strongly and selectively when exposed to familiar images, especially those seen many times before. This finding suggests that the brain uses this mechanism to track a rapidly changing visual environment and may lead to improvements in perception and cognition.
Research found that neutralizing a specific cytokine in the brain impaired cognitive flexibility in stressed and nonstressed rats. However, restoring low levels of this cytokine in a specific region of the brain corrected the deficit.
