Soccer players who feel anxious at the thought of kicking a penalty kick and who miss the goal show more activity in the prefrontal cortex. Overthinking the shot, researchers say, could play a role in missing a goal. Read More
Researchers have implicated alterations in the balance of two chloride ion channels in the cognitive deficits associated with schizophrenia. Inhibiting transporter activity with bumetanide reversed some of the cognitive symptoms in mouse models of the psychiatric disorder. Read More
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. Read More
Peripheral and brain markers for fear differ in a hormone dependent manner between males and females. Read More
Corporal punishment may detrimentally harm brain development, a new study reports. Previous studies have revealed links between spanking and psychological problems, including depression and anxiety. The new study found children who experienced spanking as a form of punishment demonstrated greater activation in areas of the prefrontal cortex in response to fearful stimuli. Read More
While the effects of hallucinogens to treat mental illnesses are being researched, little is known about the neurobiology of those who dabble in psychedelics for recreational purposes. A new study reports "psychonauts" have distinct behaviors, including taking a scientific approach to documenting their experience with hallucinogens, compared to more recreational users. Read More
Infant children whose mothers experienced neglect when they were young showed altered brain circuitry in areas associated with anxiety and fear response. Read More
Gene expression patterns in four regions of the prefrontal cortex are distinctly different in those who have been diagnosed with PTSD compared to those who have not. Major differences were seen in interneurons, which inhibit the immune system and microglia in the central nervous system. Findings shed light on why women are more likely to experience PTSD and compound a link between post-traumatic stress and a dampening of the immune system. Read More
Focusing on gene changes as a result of epigenetic processes, such as aging, researchers were able to reverse elevated levels of harmful genes associated with memory deficits in Alzheimer's disease. Read More
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. Read More
Study concludes one reason we may make unwise decisions is our preference for a positive outcome. Read More
A dynamic interplay of different brainwave frequencies, not dedicated networks, governs how the brain acts to a novel surprise and downplays predictable stimuli. Read More
