While some types of excitatory neurons respond to images and represent them in the visual cortex, the activity of two types of inhibitory interneurons combine in a circuit to reinforce visual stability and reliability.
A new statistical model lays groundwork for understanding how ketamine induces an anesthetic response, steps to monitor unconscious patients, and provides new information about brain activity while unconscious.
While the visual cortex stores individual images in the brain, the hippocampus plays a significant role in the ability to recognize a sequence of images.
A new study reveals the role the locus coeruleus plays in learning, behavior, and mental health.
As novel visual patterns become familiar, stark changes occur in the visual cortex. Gamma rhythms give way to low-wave beta waves, and the neural activity switches from PV neurons in favor of inhibitory SOM neurons.

A newly developed artificial intelligence algorithm can accurately and reliably assess unconsciousness in patients under anesthesia based on brain activity.
Propofol, the commonly used anesthetic, alters and controls the dynamics of the brain's rhythms. The findings can help doctors better monitor patients under anesthesia with the aid of EEG.
Huntington's disease may progress to advanced stages as a result of degradation of the cells' health maintenance system than due to the increased disease pathology itself.
In visual working memory, the brain immediately transfers the memory of object shifts by re-encoding the memory among neurons in the opposite brain hemisphere.
New studies are set to explore how gene expression alters the brain's response to drug abuse, and to screen for genes that could help brain cells withstand Parkinson's disease.
