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 dynamic interplay of different brainwave frequencies, not dedicated networks, governs how the brain acts to a novel surprise and downplays predictable stimuli.
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 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.
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.
A new study reveals the complex architecture of a decision-making circuit in the brains of C. elegans that prompts them to forage for food or stop once a source has been found.
Findings support modern thought that neural networks store information by making short-term alterations to the synapses. The study sheds new light on short-term synaptic plasticity in recent memory storage.
Researchers reveal how neurons set up and sustain the vital infrastructure that allows for seamless neurotransmission.
Rhythmic bursts of activity in the prefrontal cortex reduce variability as an animal focuses on a task.
Structural and functional coupling in visual areas of the mouse brain can be detected at sub-cellular resolution in vitro.
Brain cells snap DNA in more places and in more cell types than previously realized in order to express genes for learning and memory.
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.
