A new study reveals the role the locus coeruleus plays in learning, behavior, and mental health.
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.
Anterior cingulate cortex neurons project connections to the superior colliculus. The superior colliculus carries out reflexive movements. The study finds the purpose of the ACC neurons connections to the SC is to over-rider the SC when executive control is essential.
Brain mapping study reveals memory engrams are widely distributed throughout the brain, including among regions not previously realized.
Rhythmic bursts of activity in the prefrontal cortex reduce variability as an animal focuses on a task.
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.
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 new computer model shows the beneficial effects of deep brain stimulation arise from how it interrupts the cycle promoting runway beta in a circuit loop between the subthalamic nucleus and striatum.
Structural and functional coupling in visual areas of the mouse brain can be detected at sub-cellular resolution in vitro.
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.
Just one protein situated on the synapse can profoundly alter how some neurons communicate and implement plasticity.
In both human cell and mouse models of Huntington's disease, RNA from mitochondria was misplaced within spiny projection neurons. The stray RNAs, which looked different to cells than RNA derived from the cell nucleus, trigger an immune reaction that can lead to striatal cell type vulnerability.
