Brain activity refers to the various functions and processes carried out by the brain, encompassing everything from neural firing and electrical impulses to chemical neurotransmitter exchanges. This activity is the foundation of all cognitive and physiological functions, such as thought, emotion, movement, and the maintenance of homeostasis within the body. Brain activity can be measured and analyzed using various techniques such as electroencephalography (EEG), which records electrical activity along the scalp, and functional magnetic resonance imaging (fMRI), which detects changes in blood flow within the brain to map neural activity. These techniques help scientists understand how different parts of the brain work and how they coordinate complex behaviors. The study of brain activity is crucial for advancing our knowledge of neurological and psychological conditions, enhancing treatments, and even developing interfaces that connect the human brain with computers.
Study shows psilocybin induces dynamic brain connectivity, linked to profound, ego-altering experiences, potentially beneficial in psychotherapy. Researchers have discovered that psilocybin, the active compound in…
According to recent research, your brain is awakened by a stress transmitter more than 100 times each night. You wake up. The alarm clock says 02:56….
For some people, walking can boost brain function For a very long time, people have believed that when walking and a task are combined, both…
The nervous system depends upon the tightly regulated spatial and temporal communication that occurs between neurons at specialized connections called synapses. Chemical signals called neurotransmitters,…
MIT neuroscientists have uncovered a cellular pathway that allows specific synapses to become stronger during memory formation. The findings provide the first glimpse of the…
A new study by a team of University of Pennsylvania neuroscientists shows that precisely timed electrical stimulation to the left side of the brain can…
MIT neuroscientists have found evidence that the brain’s ability to control what it’s thinking about relies on low-frequency brain waves known as beta rhythms. In…
When you enter a room, your brain is bombarded with sensory information. If the room is a place you know well, most of this information…
Roughly, one in a hundred adults has problems with speaking fluently. Not much is known about the causes of persistent developmental stuttering, which is the…
Steak or ice cream? To make the choice, the brain assigns a value to each option. For example, at dinnertime, the steak may be ranked…
A new study from MIT provides evidence for an alternative timekeeping system that relies on the neurons responsible for producing a specific action. Depending on…
New research from Yale University reveals that the laminin alpha 5 molecule is crucial to the maturing of the adolescent brain. For a decade, the…
According to MIT neuroscientists, the existence of “silent engrams” suggests that existing models of memory formation should be revised. Learning and memory are generally thought…
A new study from Yale University shows that glucose levels are reduced in the brains of individuals with obesity and type 2 diabetes compared to…
New research shows that electrical stimulation can quickly — and reversibly — increase or decrease executive function in healthy people and change their behavior. Robert…
In these short videos, researchers use a glass brain and pulses of light to show how information flows between different regions of the brain. The…
New research from MIT reveals that memories are formed simultaneously in the hippocampus and the long-term storage location in the brain’s cortex. When we visit…
MIT neuroscientists identify the brain circuit that drives pleasure-inducing behavior in a brain region thought to be linked with fear. Scientists have long believed that…
