A team of researchers from the Florida State University College of Medicine has found that an amino acid produced by the brain could play a crucial role in preventing a type of epileptic seizure. Temporal lobe epileptic seizures are debilitating and can cause lasting damage in patients, including neuronal death and loss of neuron function. […]

What do the toxins from arrow-poison frogs, puffer fish and scorpions have in common with drugs against epilepsy? The answer is that they all affect the ability of nerves to transmit electrical impulses by affecting the ion channels in nerves. Ion channels are small openings in the cell membrane of nerves that open and close […]

Our thoughts, feelings, and movements are controlled by billions of neurons talking to each other at trillions of specialized communication points called synapses. In an in-depth study of neurons grown in laboratory petri dishes, National Institutes of Health researchers discovered how the chattiest of some synapses find the energy to support intense conversations thought to […]

Every region has its place in the brain. However, it has been unclear why brain regions are located where they are. Now, scientists at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) and the Forschungszentrum Jülich have defined two main axes along which brain regions are genetically organized, stretching from posterior […]

How many “listeners” a nerve cell has in the brain is strictly regulated. This is shown by an international study led by the University College London and the universities of Bonn, Bordeaux and Milton Keynes (England). In the environment of learning neurons, certain processes are set in motion that make signal transmission less exclusive. The […]

New research at Washington University School of Medicine in St. Louis helps illuminate a surprising mind-body connection. In mice, the researchers found that immune cells surrounding the brain produce a molecule that is then absorbed by neurons in the brain, where it appears to be necessary for normal behavior.

Hard skulls help protect our brains from physical injuries. In addition to a tough outer shell, brains have internal defenses, including a powerful shield called the blood-brain barrier that defends brain cells from substances in the bloodstream that are toxic and dangerous to nerve cells. If the blood-brain barrier is breached, then health problems arise. […]

Tracking the passage of time to the second is critical for motor control, learning and cognition, including the ability to anticipate future events. While the brain depends on its circadian clock to measure hours and days, the circadian clock does not have a second hand.

The brain region that according to the researchers is responsible for detecting differences between your understanding of others’ thoughts and what you think yourself is called the temporoparietal junction. This brain region is often less active in people on the autism spectrum. After re-assessing other findings from 35 years of Theory of Mind research in […]

Dynamic networks that specialize in the transmission of information generally consist of multiple components, including not only primary processors, like computers, for example, but also numerous support applications and services. The human nervous system is fundamentally very similar—neurons, like computers, process and transmit information, sending molecular signals through axons to other neurons, all of which […]
