Paying attention alters how the brain allocates its limited energy. As the brain uses more energy to process information we attend to, the less energy is supplied to processing outside our field of attention. Read More

Electrophysiology
Electrophysiology research articles can cover research involving whole cell patch-clamp recordings, voltage clamping, current clamping, multielectrode arrays, EEG, brain machine interfaces, field potentials, neural prosthetics, deep brain stimulation, synaptic plasticity and other work.
Common green apple flavorant farnesene enhances nicotine reward in mouse models. The flavorant is also rewarding on its own. Researchers say with or without nicotine, flavored vapes, especially those containing farnesene, pose potential neurological risks, including addiction. Read More
The act of remapping an area can be mathematically modeled as probabilistic reasoning in rodents. Read More
High resolution imaging reveals the human cerebellum is 80% of the area of the cortex. The findings indicate this area of the brain likely grew larger as human behavior and cognition evolved. Read More
A new human brain atlas features 250 structurally distinct areas, each based on the analysis of ten brains. Over 2400 brain sections were digitalized and assembled in 3D to create the new map. Read More
A new study provides evidence that hearing is the last sense to go during the process of active death. Many people become unresponsive during the final hours of life, however, EEG data revealed the dying brain responds to sounds throughout the final moments of life. Read More
Researchers synthesized 3D fuzzy graphene on a nanowire template to create new material for photothermally stimulating cells. Read More
Glioma brain tumors alter the function of astrocytes, possibly contributing to seizures many brain cancer patients experience. Astrocytes encasing gliomas exhibit different molecular signatures based on their proximity to the cancer cells. Those directly touching the cancer cells become elongated and swollen, mimicking the astrocyte's response to other epilepsy-related brain injuries. Read More
The anterior lateral motor cortex appears to play a significant role in context-based decision making. Read More
GABA can selectively regulate the excitability of neurons. Read More
Increased potassium currents were responsible for hyperactivity of CA3 neurons. When exposed to potassium channel blockers, the hyperactivity disappeared. However, when exposed to lithium, the drug not only reversed hyperactivity but reduced potassium currents at the same time. The findings strengthen the case that potassium currents play a role in bipolar disorder. Read More
Researchers define the proteome of neural stem cell niches and the entire set of expressed proteins. The findings shed light on key regulators of neurogenesis. Read More
